Borong BR6508 helicopter (49" long, swash plate control, 2.4ghz, 3.5ch., DVR camera
Hi everyone, I have a Borong BR6508 helicopter that Iíve been flying and thought I would try a thread on the Borong BR6508 helicopter.
I have been flying my Borong BR6508 helicopter for several months now and the BR6508 has proven to be a great 3.5 channel helicopter. I have learned a lot things about the BR6508 helicopter and have posted some information below that may help other BR6508 helicopter owners/flyers.
I also started the thread so that flyers of the Borong helicopters can share information and ideas on things such as adjusting the helicopter, post tips on setups, post about modifications, talk about flying the Borong helicopters, post videoís and photos of Borong helicopters, have a question on BR6508, post about things that you would like see upgraded on the Borong helicopters, post about best places to buy parts from, etc..
Also any input or updates by the manufacture (or a company representative) of Borong helicopters is also welcomed.
In this post I have;
1} created a list of features found on the BR6508 helicopter (and transmitter).
2} created a specification/technical data list on the BR6508 helicopter and transmitter (also includes how the controls work information).
3} created a list of interesting things found on the BR6508 helicopter and transmitter.
4} created a mini review on my BR6508 helicopter and flying it.
5} posted some photos of my new BR6508 helicopter at the very bottom of the post.
List of features found on the BR6508 helicopter (and transmitter)
1] The BR6508 helicopter is the first 3.5ch. coaxial helicopter in the 130cm size range to use swash plate control on the lower blades (controls the forward and backup flying of the helicopter).
(The BR6508 helicopter is also unique in that the lower rotor uses slightly longer main blades to help maximize the swash plateís control over the rotor system).
2] The BR6508 helicopter comes equipped with a high technology, reliable working 2.4Ghz transmitter and receiver (has strong anti-interference, double layer protection built in and has no signal drops).
3] The 3.5 channel BR6508 helicopter comes equipped with a transmitter that has real working trim buttons and several other extra control features built into the transmitter and helicopter.
4] The BR6508 helicopter comes equipped with an actual Li-Po battery.
5] The BR6508 has an unique geared transmission system for powering the main rotors.
6] The BR6508 uses a 2 piece (lower and upper) frame design. The lower frame can be removed from the upper frame for easy access to the transmission gears and lower rotor system. (The 2 piece frame makes the helicopter easier to work on and easier to take apart)
7] The BR6508 uses aluminum side plates for a light weight and strong frame. Also looks great too.
8] The BR6508ís plastic parts are made of a durable, strong plastic.
9] The BR6508 uses heavy duty blades on the main rotors. The blades are large in size, strong, very durable and have swivel limiters built in. The swivel limiters are designed to keep the main blades far away from each other so as to significantly lessen the chances of having a blade strike while flying. The BR6508 helicopter is able to handle good amounts of rough maneuvering and still keep on flying.
10] The BR6508 can be bought with optional micro DVR (video) camera pre-installed. (The DVR camera can take both videos and photos).
11] The BR6508 is a nice looking and well proportioned looking helicopter.
12] The BR6508 helicopter has future upgrade potential (The BR6508 helicopter and transmitter show hints that the BR6508 helicopter could easily be made with 4.5 channels (with side to side flying control) by the Borong factory.
13] The BR6508ís battery compartment is located on the underside of the helicopter and is easy to access. The battery compartment is large and roomy (has lots of room for using a larger size mah Li-Po battery).
14] The BR6508 helicopter is an easy to fly, super stable flying helicopter.
Below are some specification/technical data on the BR6508 helicopter and transmitter (Also included is information on how the controls work)
Note; The information below should be pretty accurate, but if anything needs changed or updated, I will update the information as it comes along.
Helicopterís Name ---- Borong BR6508 helicopter. (2014/ 2015 model was used for all information provided below).
Manufacture Name ---- Borong Factory (Borong is the name on the BR6508 helicopter box).
Unconfirmed but looks to be the Borong website (BR6508 helicopter); http://n.tyxtoys.com/EN/ShowProduct.aspx?ID=5
(Once on the website, to see links to other Borong helicopters, click on the Model Toys Factory name at top of the BR6508 page).
Note; According to several websites (that sell Borong parts) the manufacture of Borong helicopters has been around for several years. The company also makes other smaller Borong helicopters (and Quadcopters) including a 55cm long 4 channel Borong BR6808T helicopter.
BR6508 helicopterís claimed Length (includes main rotor/tail blade swing out) ---- Referred to as 130cm size on the front of the BR6508 helicopter box and by sellers. (On the side of the BR6508ís helicopter box the technical data chart has the BR6508 helicopter listed at being 1250mm in length).
Actual measured running length of my BR6508 helicopter ---- 1232mm or 48.5 inches (measurement includes main rotor blade and tail blade swing out).
Actual measured body/structure length of my BR6508 helicopter ---- 1200mm or 47.25 inches long (measurement was taken from the tip of the fuselageís nose to the outer lower tip of the landing leg on the tail end).
(Note about the BR6508Ďs size when compared to other large size helicopters. Size wise the BR6508 helicopter is actually slightly larger than other helicopters in the 125cm -134cm size range. The BR6508 uses a slightly shorter tail boom length with the swash plate controlled rotor system, but in actual stature the BR6508 is a slightly taller and wider helicopter than even the 134cm size helicopters).
BR6508 helicopterís Height ---- Listed as 40cm tall on the BR6508 helicopter box
Actual measured height of my BR6508 helicopter from the ground to the top of main rotor shaft ---- 40.8cm or 16.1 inches.
The measurement was taken from the bottom side of the landing skids holders with the helicopter resting on the ground and doesnĎt include the foam rubber grommets on the landing skids. When including the rubber grommets the helicopters actual height measurement is 41.5cm or 16.35 inches.
BR6508 helicopterís Width ---- Listed as 22cm wide on the BR6508 helicopter box.
Actual measured width of my BR6508 helicopter ---- 18.4cm or 7.25 inches.
Note; Measurement was taken from the widest part found on the helicopter itself (the landing skid holders). The measurement was taken from the outside edge on the landing skid holders with the helicopter resting on the ground and doesnít include the foam rubber grommets on the landing skids. When including the rubber grommets the helicopterís actual width measurement is 19.3cm or 7.6 inches.
Flying weight of BR6508 helicopter with 2000Mah Li-Po battery ---- 2.8 pounds (Unconfirmed at this time but that weight should be pretty close).
BR6508ís Upper Main Rotor Diameter (A blades) ---- 67cm or 26.4 inches (Actual measured size).
BR6508ís Lower Main Rotor Diameter (B blades) ---- 69.3cm or 27.3 inches (Actual measured size).
[Note; On the BR6508 helicopter the lower main rotorís overall diameter is 2.3cm (.9 inches) larger than the upper main rotor diameter].
Transmitter frequency used for BR6508 helicopter ---- 2.4Ghz frequency. (Powerful and has no signal drops)
The transmitter has automatic electronic code locking so that two BR6508 helicopters can be flown independently in same area at same time by two different flyers (using two Borong transmitters) without any radio interferences.
Note though that according to some seller websites in China the ads claim that several BR6508 helicopters can be flown in the same area at the same time by several flyers with the Borong BR6508 transmitters (unconfirmed at this time but possibly true).
Transmitter control range of BR6508 helicopter (Claimed maximum safe control range)---- From available information found so far, the rated control range is claimed to be 100+ meters out (328 feet) and 60+ meters up (197 feet). (Note; I have seen a couple Chinese websites listing the control range as far as 150 meter out and over 80 meter up, but that information could be a translating error on those websites or it could be the very outer maximum range of the transmitterĎs power).
Transmitter Controller modes ---- The BR6508ís transmitter has two mode settings (mode 1 and mode 2). The BR6508 transmitter comes from the factory set on the mode 1 setting and the mode setting can easily be changed to the mode 2 setting by holding the LED light button in for several seconds until a beep is heard.
Transmitter channels ---- Listed as 3.5 Channel on box and by sellers. For the most part the BR6508 transmitter is much like a 4 channel transmitter and has fully functional joysticks, trim buttons, and has several other control buttons.
Note about the mode settings described below - On the BR6508 transmitter the throttle is permanently set to the left side joystick and can not be switched over to the right side joystick with the mode button. Also the modes descriptions below are only applicable with using the BR6508 manual and the way the manual describes the modes. The modes listed below are only describing a mode being change and shouldnít be confused with regular RC modes configurations.
From the Borong factory the transmitter is preset to Mode 1 - The transmitterís left side joystick is the throttle and controls the climbing, lowering and hovering of the helicopter. The transmitterís right side joystick controls the forward and backup flying (fore/aft cyclic) of the helicopter and controls the left and right turning (yaw) of the helicopter. (Note; This type of mode configuration would normally be called Mode 4 on other RC transmitters)
When set to Mode 2 - The transmitterís left side joystick is still the throttle and controls the climbing, lowering and hovering of the helicopter, but will now also control the left and right turning (yaw) of the helicopter. The transmitterís right side joystick will now only control the forward and backup flying (fore/aft cyclic) of the helicopter. (Note; This type of mode configuration is called Mode 2 on other RC transmitters)
How many trim buttons on the BR6508 transmitter and what their used for ---- On the BR6508 transmitter there are (4) trim type buttons and three are used for fine tuning the joystick controls. The 4th trim looking button located just to the right of the throttleís joystick is non-trim able and rather its button is used for controlling the BR6508ís optional DVR (video) camera.
The BR6508 transmitterís main control features;
1. Transmitter power button - Turns transmitter ON/OFF with a beep. When transmitter is turned on a large blue color light will be displayed near the top/center of the transmitter. The transmitter also has low battery warning and the same blue light will start flashing when the AA batteries are low on power.
2. Left side joystick - Is the throttle for climbing, hovering, descending, Also works for left/right turning when set on mode 2 setting.
3. Right side joystick - Is the joystick for forward/backward flying, Also does left/right turning when set on mode 1 setting.
4. Led light button - Turns the LED lights OFF/ON. Also the same button is used to change the transmitterís mode setting by holding the button in for several seconds.
5. High/Low power button - Used to change the forward/backup speed of the helicopter from a slower speed to high speed.
6. Camera button - Used to turn the DVR cameraís video recording ON/OFF and used for taking photos.
7. Trim button below throttleís joystick - Trims the left/right turning movement of the helicopter when on mode 2 setting.
8. Trim button just left of the forward/backup joystick - Trims the forward/backup movement of the helicopter.
9. Trim button just below the forward/backup joystick - Trims the left/right turning movement of the helicopter when on mode 1 setting.
Using the BR6508 transmitterís control features;
A] The transmitter has a button for turning the LED lights OFF/ON on the helicopter (located at top left on the transmitter). By default the LED lights on the helicopter will come on upon turning the transmitterís power on and can be turned off at anytime by one quick press of the light button.
The light button is also used to change the transmitterís mode settings. The mode setting can be easily changed by pressing in and holding the light button in for several seconds until a loud beep is heard of which will change the transmitterís mode setting (the mode setting can be changed from Mode 1 to Mode 2 and back again).
Note; It should be noted too that whenever changing the mode setting on the transmitter that the trim settings will also be effected. Once the transmitterís mode has been changed to a different mode setting, the trim buttons may also need to be readjusted upon flying the helicopter for the first time after the mode change.
B] The transmitter has a camera button for controlling the micro DVR (video) camera on the helicopter (located just to right of the throttleís joystick and looks like a throttle trim button). A quick push up one time on the camera button will take one photo (with each push up on the button the transmitter will beep once and take a photo). One push down on the camera button will start video recording (the transmitter will do a longer beep upon starting of video recording). To stop video recording push the camera button down once again (and the transmitter will do a longer beep once and stop the video recording). The cameraís videos/photos can be easily uploaded to a computer by using the USB cable (one comes with the Borong helicopter) and plugging the small end into the back of the DVR camera and plugging the other end of the USB cable into the computerís USB port. The recorded video/photos can also be uploaded by removing the micro SD card from the side of the BR6508ís DVR camera and installing the micro SD card into a SD card adapter/reader for uploading them directly onto a computer.
Also whenever using the USB cable to upload the videos/photos to a computer, the BR6508ís Li-Po battery doesnít need to be connected to the helicopter. Upon connecting the BR6508ís DVR camera to a computer with the USB cable the DVR camera will automatically receive power from the computer for the uploading process. Also a blue color LED light will light up on the bottom of the camera showing that the camera is getting power and is ready to start the uploading process.
Note; depending on viewing angle the blue color LED light can generally be observed from the sides of camera or seen reflecting off the surface underneath the helicopter saving time of actually having to pickup the helicopter up to look at the blue LED light directly.
How to check that DVR camera is recording once the camera button is pushed on the transmitter;
First set the throttleís joystick on the transmitter to the OFF (down) position (Note; Use extreme caution and never touch or move the throttle during these next procedures). Next turn on the power on the transmitter. Next carefully lift the helicopter up overhead (or off to the side) so that the bottom of the video camera can be seen. (Note; Always make sure to lift and hold the helicopter so that the main blades are totally clear and leaned away from the body and face). Next carefully turn the helicopterís battery power on by using the ON/OFF switch on the helicopter. Upon the helicopterís power being turned on a little blue LED light will come on (at bottom of camera) showing that the DVR camera is powered up and ready to start recording. Next on the transmitter (be very, very careful to not touch the throttle) push the camera button down once (it will beep and start the video recording) and a little red LED light will also come on at the bottom of the video camera and will stay on during the video recording. (Note; Whenever the little red LED light is on means that the video camera is recording a video).
To stop video recording, push camera button down once again (a beep will be heard) and the camera will stop recording and the little red LED light on the bottom of video camera will go off.
Also anytime the camera button is pushed up once for taking a photo the same little red LED light on the bottom of DVR camera will quickly flash on/off once for each photo taken.
(Note; To prevent videos uploading file error always stop each video recording by using the camera button on the transmitter before turning the power off on the BR6508 helicopter. The reason is that by stopping the DVR camera recording by using the helicopterís ON/OFF power switch can cause that particular flights recorded videos to not be saved properly onto the micro SD card and can result in possible lost of that flightís recorded videos).
C] The transmitter has a High/ Low power setting button (located at top right on transmitter). The BR6508 helicopter has two levels of speed for flying. The purpose of the two different levels of power is that when set to the low power setting, the low power setting will limit the helicopterís forward flying speed and backup flying speed for 1st time flyers.
(NOTE; The low power setting is the automatic default setting on the BR6508 transmitter. The BR6508 transmitter will automatically default back to the low power setting once the transmitterís power is turned off. To fly the BR6508 helicopter on the high power setting; the High/Low button must be pushed each time the transmitter power is turned back on).
Also it should be noted that the High/Low power button only changes the forward/backup speed of the Br6508 helicopter. The BR6508ís throttle and takeoff power will stay the same regardless of the power setting selected.
Below is a quick visual method to verify which power setting the transmitter is set on before flying the BR6508 helicopter;
First set the throttleís joystick on the transmitter to the OFF (down) position. (Note; Use extreme caution and do not touch or move the throttle during these next procedures). Next turn on the power on the transmitter. Next with the helicopter resting on the ground turn on the helicopterís power by using the ON/OFF switch. Next on the transmitter carefully push the forward/backup joystick to the full forward speed position (the joystick position for flying the helicopter forward at full speed) and hold it there. While holding the forward/backup joystick in the full forward speed position, next push in on the High/ Low power button until a beep is heard and observe how much the servoís arm moves upward (by looking in from the back right side of the helicopter, also make sure to stand clear of the blades). The servoís arm should of move up to a higher position when the High/Low power button was pushed and a beep was heard. The higher up arm position means that the transmitter is now set on the high power setting. If still not sure about the power setting, just repeat the process by pushing in the High/Low button again while holding the forward/backup joystick to the full forward speed position. Once the transmitter is set on the high power setting the servoís arm will be able to go higher up and will now have a longer throw movement.
Also once the transmitter is set on the high power setting, the servoís arm also gains more downward throw movement for more backup speed whenever the forward/backup joystick is pushed all the way downward.
D] The transmitter has a blue colored power indicator light (located towards top center of the transmitter). Upon turning on the transmitterís power a blue color power indicator light will come on and the transmitter will beep once, meaning that the transmitter has good battery power and the helicopter is ready to fly. If the blue light is flashing means that the battery power is low on the transmitter and that the batteries will need to be replaced or recharged.
E] The BR6508 transmitter has (3) fine tune trim buttons. One trim button is located just below the throttle joystick, One trim button is located just to the left of forward/backup joystick, One trim button is located just below the forward/backup joystick.
F] When a trim button is pressed to one side or the other and held there, the trimmer will run through itís range of setting while beeping on each trim adjustment movement as it goes along. Also when running a trimmer through itís settings and beeps, the trimmer will make a different type beep whenever the trimís center position is found. Also whenever the trimmer reaches the maximum end limit of the trim adjustment, the trimmer will make a different louder sounding beep tone. Each trim button can also be fine tuned by quickly pushing the trim button once for making a smaller (one beep) adjustment.
Batteries size used in the BR6508 transmitter ---- The BR6508 transmitter uses (6) AA size batteries (Rechargeable type AA batteries can be used).
Mechanical method used to make forward and backward speed on BR6508 helicopter ---- The BR6508 uses a servo and swash plate to control the thrust angle of the lower main blades so that the helicopter can fly forwards and backwards.
Mechanical method used to climb, hover, land the BR6508 helicopter ---- The main rotors rpmís is controlled with the throttle so that helicopter can climb, descend, hover.
Mechanical method used to turn the BR6508 helicopter ---- The upper and lower rotors rpmís can be varied by using the turning joystick so that the helicopter can turn left or right.
Mechanical method used to keep the BR6508 helicopter pointed straight ahead ---- The BR6508 helicopter has an electronic gyro on the PCB board that automatically modulates the upper and lower rotors rpmís so that the helicopter will hold straight when hovering and so that the helicopter can hold a stable straight line when flying straight ahead (also helps the helicopter to fly straighter in shifty air).
Motor size and type used on BR6508 helicopter ---- (2) 540 motors (according to the BR6508 helicopter box). The motors are large in size and each motor housing measures in right around 50 mm tall x 35mm diameter. The BR6508 motors are brush type and make strong power.
Battery size and type used in BR6508 helicopter ---- 11.1 volt, 2000mah Li-Po (3 cell) [Note; The BR6508ís helicopter box says that the BR6508 helicopter comes equipped with a 2200mah battery, but apparently itís a print error on the box since all new BR6508 helicopters thus far are coming equipped with the 2000mah size battery].
Li-Po Battery weight ---- The BR6508ís 11.1 volt 2000mah battery weights 5.25 oz. (plus/minus .05 oz.)
C rating of the 2000mah Li-Po Battery (Continuous discharge rating) ---- Actual C rating of the battery is currently not known (But when using size and weight as a rough gauge the stock battery is around a 15C-20C battery in build).
Average Battery charging time according to various websites ---- Around 180 minutes. (Note; I have found that my BR6508ís 2000mah Li-Po battery requires close to 4 hours (when fully discharged) to fully charge it up again when using the stock 500ma (.5 Amp) battery charger. (Recently Iíve been using an aftermarket 1 amp charger and it will charge the stock 2000mah battery in 2 hours).
Note; In my above description fully discharged means that the battery power is down to the point of where the helicopterís power starts to fade quickly requiring more and more throttle to stay up and the helicopter has to land.
Flight time of BR6508 helicopter on fully charged battery ---- Various internet sellers list the flight times as being around 7 to 8 minutes. (Actual Factory claimed flight time is not known at this time).
[Note; With my BR6508 helicopter the flight times are averaging right around 5 Ĺ minutes with the stock 2000Mah Li-Po battery].
Plastic type used on BR6508 helicopter ---- Some suppliers/sellers advertise the BR6508 plastic as being ABS. (Unconfirmed at this time). The plastic is strong and durable though.
BR6508 helicopterís main frame side plate material --- Aluminum.
Colors available ---- Red color is currently available. A couple of websites have listed a Blue color as an option (But not confirmed at this time if the Blue color is or will be an option on the BR6508 helicopters).
Manual that comes with BR6508 helicopter ---- The manual that comes with the BR6508 helicopter only shows a 2.4GHZ Borong helicopter in general and has very basic information, but is still helpful for 1st time flyers. The manual also shows side to side flying (sideways flying) control information for a 4 channels control helicopter. (Note though that the BR6508 helicopter doesnít have an actual 4th channel control yet and maybe the manual information is a hint to whatís to come in the near future on the BR6508 helicopters).
The BR6508 helicopter also comes with a basic assembly instruction colored page (with parts list) and a printed paper showing basic how to use the DVR (video) camera.
(Unfortunately the Borong company has no contact information or website listed in the manual, or on the instruction/ parts list page, or on the DVR camera page).
There are two options of BR6508 helicopter being sold at this time;
1] The BR6508 helicopter can be bought with a DVR (video) camera already installed on the helicopter.
2] The BR6508 helicopter can also be bought without the optional DVR Camera.
Some features of the BR6508ís DVR (video) Camera;
The DVR camera can take both videos and photos (all videos and photos are taken in color).
The DVR camera comes with a 2G micro SD card installed. (the class of card is not known at this time, but a good guess would be itís a class 4 card).
Records videos at 30 frames per second.
The DVR camera records in very good color and detail for itís super small size.
Videos play pretty smooth without any real noticeable frame freezes, skips, excessive wallowing from vibrations, etc..
The camera can record good videos even in lower light situations such as cloudy days, late day, etc..
The cameraís videos can be converted easily with a video converter for putting them on DVD, You tube, etc. (Free video converters can be downloaded from the internet that work well for converting the BR6508ís videos).
The videos are 640 x 480 frame size (according to a video converter). Note; According to Windows media player the converted videos are listed to be playing at 720x480 frame size.
The videos also look good even when watched at full size on a computer monitor or on large TV.
The DVR camera isnít HD, but the DVR camera does take pretty decent quality videos for its size.
The DVR cameraís video coding ------ (M-JPEG)
How to upload videos/photos from the DVR camera to a computer using the Borong USB cable; With the helicopterís power turned off (I also unplug the helicopterís battery) first plug the small end of Borong USB cable into the back of the DVR camera. Next plug the other end of the USB cable (the large end) into the computerĎs USB port with the computer turned on. Upon connecting the DVR camera and computer together with the USB cable the bottom of the DVR camera will display a small blue LED light meaning that a good connection is made with the computer and that the DVR camera is now communicating with the computer. After a couple of seconds or so of being connected to the computer the DVR camera will automatically display a dialog box (pop-up box) on the computer screen. In the dialog box select and click on import pictures and videos. (Note; Depending on device setting and which dialog box opens automatically, might first have to select and click on ďOpen folder to view filesĒ to see the import pictures and videos dialog box). Once import pictures and videos dialog box has opened, type in a folder name and then click on the import button to start the uploading of the cameraís videos and photos to the computer.
How to manually erase the micro SD card during the uploading process; If the cameraís import settings havenít been set to automatically erase the micro SD card after each importing, the micro SD card can be erased manually by selecting the erase after importing box located towards bottom of the import pictures and videos dialog box as the videos/photos are being uploaded. Note though that the erase after importing can only be selected if the uploading process runs long enough for it to be selected such as during a longer video or multiple photo uploading. By manually selecting the erase after importing box the micro SD card will be totally erased immediately after the uploading of the videoís and photoís is completed by the computer.
How to set the import settings to automatically erase the micro SD card after each uploading; The import settings can be set to erase the micro SD card automatically after each upload by clicking on import setting located at bottom of the import pictures and videos dialog box and then selecting the always erase from device after each importing.
How to remove micro SD Card from DVR camera; The micro SD Card is easily removed from the DVR camera by pushing in lightly on it with a finger until a click is heard, then release the finger pressure and lightly pull on the micro SD card to remove it.
How to install micro SD Card into DVR camera; The micro SD Card is easily installed into the DVR camera by lightly pushing the micro SD card in with a finger until a click is heard.
Note; When installing the micro SD Card into the DVR camera (with the BR6508 helicopter held upside down), the brass electrical contacts end goes in first with the brass contacts facing in towards the battery compartment of the helicopter. Note that when looking at the side edges of the card that the smooth side edge of the micro SD card always faces towards the back of camera when installing it. In other words the latch part of the card will face towards the front of the DVR camera when installing it.
How to access DVR camera software with computer; Can access a couple of basic folders - video and photo folders. (Currently not known if more is accessible and will update the information here when known).
BR6508 helicopterís top speed (estimated) --- Around 5 to 8 mph (with transmitter set on the high power setting).
The speed posted above is a rough estimate and was estimated when flying my new BR6508 helicopter on calm air days.
The BR6508ís top speed can vary depending on whether the BR6508 helicopter is flying with or against air movements.
Note; By making an adjustable control rod to fine tune the swash plate and making one other small modification I was able to increase the top speed on my BR6508 helicopter (now its around 11 to 14 mph) and I will post more information about it in a future post.
The BR6508 helicopterís flying ability in moving air --- The BR6508 helicopter has the capability to fly in breezy air (can easily hover and steer in moving air), but the helicopterís forward motion will come to a stop when attempting to fly against anything stronger than a barely noticeable breeze (a rough guess would be around a 5 mph breeze).
Note; When I added a little more speed into my BR6508 helicopter as mention above my BR6508 also gained a little more forward and backup moving power for flying against a slight breeze.
Approximate price of a new BR6508 helicopter (includes transmitter and optional camera) ---- Around $140.00 - $170.00
Note; Since the BR6508 helicopter is rather new to the market and market availability is somewhat limited at this time, the BR6508 helicopter prices can vary widely depending on where the helicopter is bought from. Also as more sellers begin to sell the BR6508 helicopters the prices should come down some in the future.
Where parts can be bought for the BR6508 helicopter ---- At this time eBay generally has one or two sellers selling the BR6508 helicopter parts. There are also several other internet websites selling the BR6508 helicopter parts, but at this time donít have any information on them. As the BR6508 helicopter gains flyer interest, more places to buy parts from should become available on the internet and eBay in the near future.
Below is a list of interesting things found on the BR6508 helicopter and transmitter.
1] The BR6508ís transmitter has a nice wide base so that the transmitter will stand up easily. The wide base on the transmitter comes in handy when sitting the transmitter down in a limited space area and lessens the chance of it tipping over.
2] The BR6508ís 2.4G transmitter doesnít use the old style telescopic antenna. The BR6508 2.4G transmitter uses a small internal antenna of which makes it much easier to move the transmitter around without snagging an antenna on something and breaking the antenna. The BR6508 transmitter is powerful for its size and the little folding black plastic antenna on top of transmitter is actually only used for looks (the actual antenna wire is only about 2 inches long and is totally concealed inside the transmitter itself).
3] The BR6508ís transmitter has (2) molded in holes on the top back part of the transmitter for attaching an optional handle for carrying the transmitter by hand. (Unfortunately from what I have seen so far none of the BR6508 transmitters come supplied with the carrying handle. Hopefully in the near future the BR6508 transmitters will come with a carry handle already attached on it for easy hand carrying). Regardless of having no carry handle thought the BR6508 transmitter is pretty easy to grip and hold onto from the sides due to the unique rounded sides and the backside having a nice deep-set (sunken in) design and the sunken in shape around the joysticks. On the front of the BR6508 transmitter it also has a small center pin (or nub) with a hole in it for hooking on an aftermarket strap so that the transmitter can be carried with the flyers neck.
4] On the BR6508 transmitter both joysticks are fully functional and the transmitter actually has many working features similar to a 4 channel transmitter. The way the BR6508ís transmitter is laid out and operates gives the impression that a 4th channel control could easily be added on by the Borong factory so that the helicopter can be made to fly sideways. Currently though the BR6508ís PCB/receiver board doesnít have the extra socket for a 4th channel control, but the PCB board does have an extra socket for adding more LED lights onto the helicopter.
[It would be great to see a 4 channel version of the BR6508 helicopter (so that the helicopter has sideways flying) become available from the Borong factory of which would give flyers two great options to choose from when buying the BR6508 helicopter].
5] The antenna wire on the BR6508 PCB/receiver board is only about 2 inches long and doesnĎt touch anything on the helicopter itself. Itís really great that the antenna wire is small and not visible on the outside of the helicopter of which gives RC helicopters a more realist look and makes working on the helicopter much easier too (no long antenna wire to deal with).
6] The transmitter itself has an on/off switch for the LED lights (A really nice feature to have so that the LED lights can be turned off and on at any time, even while flying).
7] The transmitter gives off a beep whenever the transmitter is turned on. The transmitter will also give off a longer beep whenever a video or photo is taken. Its also great that the BR6508 transmitterís buttons will beep upon each push so as to let the flyer know that the button is working and doing its job.
8] The joystick used for the throttle on the BR6508ís transmitter doesnít use those problematic binding/safety resets.
(I personally really like this type of throttle setup since it is a much more reliable system and eliminates the chance of the transmitter automatically shutting the power off on the helicopter while its flying). I have done 70+ flights with my BR6508 helicopter so far and the transmitter has worked 100 percent perfectly. The main thing though is to always double check to make sure that the throttleís joystick is set to the OFF (down) position before turning on the power switch on the helicopter.
9] The BR6508ís main blades are large in size and each blade has two molded on swivel limiters located at the bladeĎs root area. The molded on swivel limiters limit the bladeís swivel angle resulting in the blades staying much farther away from each other whenever they swivel back. The swivel limiters work great at preventing blade strikes from happening allowing the BR6508 helicopter to handle faster, more aggressive maneuvers without the fear of the main blades hitting each other while flying.
10] The main blades on the BR6508 helicopter have unique raised hubs molded in around the pivot holes on each blade of which results in more precise fitting main blades. Also the pivot bushings are plastic and molded onto the blade grips of which gives the pivot bolts a bit of adjustability on tightening them. The blade grips/holders work well and do a nice job of limiting the up and down play in the pivots resulting in nice, well fitting main blades.
11] The BR6508ís main rotor blades are large in size, very durable and have strong leading edges. The blades also have a nice wide airfoil shape that help stiffen the blades and works great for maximizing thrust. The BR6508 helicopterís blades are well made blades and are very resistant to impact gouging, very resistant to chipping and very resistant to breakage.
12] The balance bar on the BR6508 helicopter is extra heavy duty for durability and the bar is made in a special oval shape to reduce air drag when spinning. The main part of the balance bar is made of a stout, flexible plastic of which improves durability and lessens the chance of the balance bar causing damage to the blades in a crash or tip over. The balance bar itself is attached to a well made, nice looking aluminum mount on top of the inner rotor shaft. The aluminum mount is removable from the inner shaft and can be removed from the inner shaft by using an Allen wrench and loosening two small Allen (hex) bolts. The aluminum mount also has an aluminum top hat (a thin red color disc) screwed onto the top of the mount that helps protects the balance bar linkages and helps limit the balance bar from over pivoting.
13] The BR6508 helicopter uses a sturdy walled steel tube for the outer rotor shaft. The .0325 thick wall on the outer rotor shaft allows for deeper screw penetration by the lower rotor hub resulting in a good secure anchoring of the lower rotor hub to the outer shaft. Also the upper main gear is held onto the outer rotor shaft with a brass collar and the brass collar has two screws that screw directly into two small holes on the outer rotor shaft. The setup works great and the two screws prevent the main gear from ever slipping on the outer rotor shaft. The lower main gear that attaches to the inner rotor shaft also uses a similar setup except that the inner shaft has notches for the screws to lock into so as to prevent the main gear from ever slipping on the inner rotor shaft.
14] The BR6508 helicopter can be purchased with the optional DVR (video) camera. The video camera is super small (might be the worlds smallest) and actually takes pretty nice videos for its size. Also the cameraís lens can be manually adjusted (swiveled) to look straight forward or adjusted downward somewhat for different camera recording views. The BR6508ís camera can also be uploaded to a computer (using the supplied Borong USB cable) even with the helicopterís battery unplugged. The DVR camera also has a micro SD that can be easily removed for uploading videos or for replacing the micro SD card.
15] The BR6508ís motors are extra large in size and make strong power. Both motors are identical and have their pinion gear mounted in close to the motorís housing so as to have minimal shaft over hang. By keeping the motor shaft over hang to a minimum makes for an excellent rigid motor to gear setup.
16] I have found that the BR6508ís motors barely get warm even when flying non-stop during a 5 minute flight. The BR6508 motors are heavy duty and each motor has several air cooling slots on their housings and internally built-in fan (paddles) to help keep air moving through them. (Note; Even though the BR6508ís motors are just beginning to get warm after a 5 minute flight, I have found that the BR6508ís 2000Mah battery is being pushed pretty hard and can heat up pretty good. I have found that the BR6508ís stock battery can provide a little longer flight times when flown for about 3 minutes and then land to allow the battery to cool down for a few minutes before finishing the battery with the last few minutes of flight).
17] The BR6508 helicopter uses an unique step type gear reduction system for powering the main rotors. The large main gears are made of a heavy duty looking plastic and look to be well made. The smaller plastic gears (that mesh against the pinion gears on the motor shafts) are backed up by thin brass gears that are laminated to one side on both small plastic gears. The thin brass gears are attached to the side of the small plastic gear with two small screws and was probably done this way to add strength to the teeth of the smaller plastic gears while at the same time helping to hold the weight down on the gears. A secondary reason too (for having the laminated brass gears) may have been to try to help limit the gear noise on the BR6508 helicopter of which is pretty distinctive. Overall though the gear system looks to be a well made and strong setup.
(On my BR6508 helicopter after 70+ flights the gears have proven to be durable and are still working like new).
18] The Borong company uses a nice quality, very durable plastic on the BR6508 helicopters. The plastic on the BR6508 is strong and is very resistant to cracking.
19] The BR6508ís transmitter works excellent and flawlessly. After 70+ flights with my BR6508 helicopter, the BR6508 transmitter has worked great with 100 percent no problems or signal loses. I have found that the 2.4Ghz BR6508 transmitter works excellent and has been 100 percent reliable. My BR6508ís transmitter hasnít had anything break on it and hasnít had any power or control issues.
20] The BR6508 helicopter has a very nice LED light setup and has a very bright LED headlight. The BR6508 also has (5) LED lights on each side of lower frame. The BR6508 also has a (5) LED light strip that runs under the tail boom and goes from the fuselage boom mount back to the wing mount located at the middle of the boom.
Its also great that the PCB board has an extra LED socket so that flyers can add an extra LED light (or bar set) onto the BR6508 helicopter when needed.
21] The BR6508 helicopter has lots of space in the battery compartment (a much larger mah Li-Po battery will easily fit into the compartment and still have space left over). The large battery compartment also works great for tucking in the Li-Po battery wires so that they canít be seen from the outside of the helicopter.
22] The BR6508 helicopter has excellent lifting thrust/ takeoff power. The BR6508 motors are powerful and can develop lots of blade thrust instantly.
23] The BR6508ís DVR camera is super small and flat shaped and only weights a few grams. The camera is located in a good protected area on the underside area of the fuselage (mounted to the frameís body) and is easy to access. Also the camera can be easily removed from the helicopter by removing (4) little screws and unplugging one small power wire.
(My Mini review) - After 70+ flights hereís my impressions of the BR6508 helicopter and transmitter.
When starting the 1st flight with my new BR6508 helicopter, one of the first things that I noticed right off was that the BR6508 helicopter has strong takeoff power. To make the BR6508 takeoff, about half throttle was enough to lift the helicopter off the ground and hover it. Applying heavy throttle at takeoff will make the BR6508 helicopter jump off the ground instantly and climb at a very fast rate. For itís size the BR6508 helicopter has excellent lifting power and can climb fast when needed.
When flying my BR6508 helicopter I have found the BR6508 to be a really smooth flying helicopter. With the BR6508 helicopter perfect throttle control isnít critical since the BR6508 helicopter has an excellent ability to hold its flight height consistent making for easy flying. One reason that the BR6508 helicopter holds the flying height consistent so well is that the throttle response of the BR6508 is fast (able to make quick height corrections) and that the large motors tend to hold a bit of momentum of which helps to keep the helicopter from losing height as fast whenever the throttle is backed off a little too much. I also found the BR6508 helicopter to be a super stable flying helicopter and the BR6508 doesnít over react to the joysticks movements of which makes the helicopter very easy to control.
The BR6508 helicopterís forward moving speed isnít super fast, but the BR6508 does fly forward in an easy to control, very stable and smooth fashion. When accelerating from a hover position, the Br6508ís helicopter has a very controllable acceleration and can respond instantly to move forwards or backwards when needed.
The BR6508 helicopter is also easy to control when making minor hover corrections and when doing smaller more precision type corrections. The BR6508 helicopter is so controllable that I could land my helicopter on virtually the same landing spot (and can even land on a small 14Ē x 14Ē patio table) with a bit of gradual movement maneuvering.
When it comes to hovering the BR6508 helicopter, the BR6508 has a super stable hover ability and can hold its hover position with ease, often times with little to almost no counter steering input needed to keep it there.
Another thing that I noticed when flying the BR6508 helicopter is that the steering is quite smooth and progressive which makes controlling the direction in which the helicopter is flying rather easy. With the smooth progressive steering the BR6508 is easy to control and doesnít have a tendency to over-steer or become squirrelly, even when making a fast turning correction. When flying along and making turns with my BR6508 helicopter, I could actually fly the BR6508 helicopter around with nice smooth arching type turns (kind of like a car driving around a bend). The BR6508 helicopter also has a very strong turning power and can be made to turn quickly, can be made to turn tight, or can be made to spin around in place quickly when needed.
When it comes to the BR6508ís 2.4Ghz transmitter, the BR6508ís transmitter has worked flawlessly for controlling my BR6508 helicopter. After doing over 70 flights with my BR6508 helicopter the 2.4Ghz system has worked great, has been 100 percent reliable and has had no frequency drops (not even a sputter). Even though I havenít really put the BR6508ís Ghz system to a long distance test, I have often flown my BR6508 helicopter as far away as 200 feet out and around 150 feet up and have not had one glitch or sputter. The Br6508ís 2.4Ghz radio system is definitely a strong and reliable system that really inspires confidence when flying a helicopter. The joysticks on the transmitter have good progression built into the joystick movement of which makes controlling the BR6508 helicopter easy. The transmitter buttons all worked great and will beep whenever pushed so as to let you know that they are working and functioning. The joystick trim buttons also worked great and will beep during each push of their buttons. When using the trim buttons, they can be quickly pushed once for a one beep fine tune adjustment, or the trim button can be held in longer for a larger multi beep trim adjustment. The trim adjustments can be done while flying or on the ground.
When it comes to the flight times I have been getting with my BR6508 helicopter, I have found that whenever flying my BR6508 helicopter nonstop I get right around 5Ĺ minutes of flight time with the stock 2000Mah battery. I also found with my BR6508 helicopter that flying it with 2 shorter flights (by using a 4 or 5 minute rest in between those flights) that the stock batteryís flight time was extended by about 30 seconds or longer. I think the reason why the flight times got better with a few minutes of rest in between the shorter flights was that it gave the battery time to cool down a bit in between flights. With the Stock 2000Mah battery I have found that the large BR6508 helicopter really stresses the stock battery pretty hard resulting in the Li-Po battery becoming borderline hot when doing a nonstop flight. The stock 2000Mah battery that comes with the BR6508 seems to be a good quality battery, but the battery does give indication that itís a bit undersize on C rating for the large size BR6508 helicopter. The stock 2000Mah Li-Po battery works well for flying the BR6508 helicopter, but nonstop flights do push the stock batteryís limits heat wise.
The good news is that larger mah batteries can be used and work great on the BR6508 helicopter (see my no. 8 paragraph further down).
I also have found it pretty amazing too that even after 5Ĺ minutes of non stop flying with my BR6508 helicopter that the BR6508ís big motors are just starting to get warm to the touch. The BR6508 has some really large size motors (a type of 540 motors according to the information listed on the BR6508 helicopter box) and they are powerful and handle the weight of the BR6508 helicopter with ease.
When it comes to the DVR (video) camera on my BR6508 helicopter, the micro size DVR camera actually works very well for its size. Even though the camera is incredible super small and has a camera lens about the size of the tip of a ball point pen, the BR6508ís video camera actually takes pretty nice quality videos, even in low light situations. On my helicopter the DVR camera took some pretty nice quality videos, but for individual photo taking the photo quality was of lower quality (more grainy or fuzzy) than what the video quality is. Overall though I feel that the camera works really well considering that the BR6508ís DVR camera is most likely a 1st version, new type of micro DVR camera. I also really liked the unique way that the micro DVR camera is mounted to the bottom of the BR6508 Helicopter. The super thin DVR camera is mounted in an excellent location on the underside frame of the helicopter that is well protected, while at the same time allowing easy access to it for plugging in the UBS cable or removing the micro SD card. Also another nice feature of the BR6508ís DVR camera is that the cameraís lens housing can be easily and instantly finger adjusted to look more straight ahead or angle downward to about 45 degrees for a slightly different recording view.
To sum things up, I have found the 3.5ch. BR6508 helicopter to be a really great helicopter that is actually well made, easy to fly, super stable flying, very durable for its size, runs great, never falls out of the sky, has a very reliable 2.4Ghz system, has a great working video camera as an option, is pretty easy to work on, has strong takeoff/climbing power, and is a really fun to fly large size helicopter.
P.S In the next post below I have posted some things that I did on my BR6508 helicopter that may help other BR6508 helicopter flyers.
Below are some photos of my new BR6508 helicopter and its transmitter
Joined Feb 2011
Below are some things that I did on my BR6508 helicopter that may help other BR6508 helicopter flyers;
1. I made a little pull tab on the battery holder tab so it can be removed easier.
I made a little pull tab on the battery holder tab by using a 1Ĺ inch long piece of clear scotch tape and then stuck one end of the tape (about Ĺ inch or so) onto the flat front side of the battery holderís plastic tab. I then doubled the other end of the tape back onto itself leaving about ĺ inch of the tape stick out for a pull tab. By making the little pull tab on the battery holder tab makes the battery holder tab easier to grab onto and easier to remove from the helicopter. Also the screw itself can be left in the hole of the battery holder tab during the tabís removal from the helicopter. The little pull tab also makes it easier to guide the battery holder tab back into the slot of the battery compartment (with the screw in the tab) so it can be tighten down with the Phillips screw driver.
2. Before flying my new BR6508 helicopter for the 1st time, I checked all screws on my helicopter to make sure they were tight.
On my new BR6508 helicopter I did find three screws that were slightly loose on the aluminum side plates. I also found that two of the pivot bolts/nuts on the main blades needed tightened a little more and I tightened them also.
On my BR6508 helicopter I was able to tighten the blade pivots down perfectly so that there was zero up and down play on the main blades.
3. When putting the tail boom on the BR6508 helicopter always make sure that the (2) little metal pins that hold on the upper support rod are pushed in all the way into the plastic mounts.
The metal heads of the little pins must be pushed in so that the head of the pin goes in all the way between the little plastic nubs on the plastic mounts. Failure to push the pins in all the way can result in the pins falling out of the upper support rod.
On my helicopter as a failsafe measure I also cut two thin pieces of black vinyl electrical tape (about 1/16Ē wide x 2Ē long) and wrapped both upper support rod mounts so as to cover the head of the pins. By wrapping the mounts with the vinyl tape covers the heads of the pins and totally eliminates any chance of the pins working loose while flying.
4. Before recharging the BR6508ís Li-Po battery I always let the battery cool down to room temperature after each flight.
I have found that the BR6508 helicopter really stresses the stock 2000Mah battery causing it to heat up considerably, especially when doing a non stop flight. I always let the battery cool down to room temperature before connecting it to the battery charger.
5. Before removing the servo from my BR6508 helicopter for the first time; I first completely removed the aluminum side plate (with the servo attached) from the helicopter and then removed the servo out through the back side of the aluminum side plate.
The reason for removing the servo this way the first time around is because the clearance slot (for the servoís power wire) on the aluminum side plate is a little tight and can cut into the servoís power wires if the servo is pulled straight out from the outside of the helicopter.
Hereís how I removed the servo for the first time from my BR6508 helicopter. I first removed the BR6508ís plastic body/fuselage from the helicopter. I then disconnected the servoís control rod from the ball joint on the swash plate and then completely removed the servoís control rod from the servo arm. I then unplugged the servo wires from the PCB board. I then removed the screws from the aluminum side plate and removed the aluminum side plate from the helicopter with the servo still screwed onto it. I then removed the (2) little screws on the servo retainer and removed the servo retainer. I then lightly pushed and wiggle worked the servo back out through the backside of the aluminum side plate.
Once the servo was removed from the aluminum side plate, I then used a little round needle file to lightly radius the inside/outside edge of the servoís mounting hole on the aluminum side plate. By lightly rounding the square (sharp) edge from around the servoís mounting hole on the aluminum side plate helps the servo to slide in and out much more easily without catching on the plateís edges. I also raised the clearance slot on the aluminum side plate (just above where the servoís wire will come through) by about 2 to 3 mm. By making the clearance slot a little taller allows the servo to be removed much easier from the outside of the helicopter the next time (no need to remove the aluminum side plate the next time around) and the servoĎs wires will have the extra clearance needed to easily come through without catching on the aluminum side plateís edge.
6. The little screw that holds the thin aluminum red disc (or top hat) located on top of the rotor shaft should be checked for tightness after every couple of flights or can be kept tight by using a low strength Loctite thread locker.
On my BR6508 helicopter the little screw holding on the top hat had a tendency to work loose every couple of flights or so no matter how tight it was tightened. I permanently solved the screw loosening by using a micro drop of a low strength Loctite thread locker on the threads of the little screw. By using the low strength Loctite thread locker the little screw stays tight and the little screw can still be removed with a Phillips screw driver when needed.
7. On my BR6508 helicopter I added 1.25 ounces of weight to the inside bottom of the body shell/fuselage (up near the LED headlight) to compensate for a slightly tilted back swash plate alignment.
Upon flying my new BR6508 helicopter for the first couple of flights I noticed that my BR6508 helicopter had a tendency to drift backwards on takeoffs and a tendency to drift backwards when hovering. After a little trim adjusting on my BR6508 helicopter I soon realized that the drifting wasnít due to the BR6508 helicopter being tail heavy, but rather that the servoís metal control rod was made a hair short at the factory resulting in the swash plate being slightly bias (leaning a couple of degrees or so) towards the rear of my helicopter. I first tried compensating for this by adjusting the forward/backup trim button on the transmitter so as to add in more forward trim to the helicopter. While adding in more forward trim did stop the drifting back on takeoffs and hovering, I also noticed that the servoís arm was now centering up too high from its correct centering point with the new trim setting (with correct centering the servo arm should be pointing straight outwards). Since the servo arm was now centering up higher, the servo armís upward throw (movement) had become shortened of which was causing the helicopter to have little forward speed, while at the same time the helicopter had about doubled itís backup speed.
I then did a quick temporary fix by adding 1.25 ounces of weight onto the front of my BR6508 helicopter of which allowed the servoís arm to be adjusted back to correct center (the extra nose weight was helping to counter the tilted swash plate) so that the helicopter would trim out better. By adding the weight to the front of the helicopter helped eliminated the back drifting on takeoffs and hovering, and also added back more forward speed to the helicopter.
Its interesting to note too that by adding on the 1.25 ounces of weight onto my BR6508 helicopter that the extra weight had no real noticeable effect on the helicopterís takeoff power, flight time, or the performance of the helicopter. During the flight tests I even flew my BR6508 helicopter with 3 extra ounces of weight on it and the BR6508 easily handled the extra weight with no problem (like the extra weight wasnĎt even there).
(UPDATE NOTE; Since that time I have made an adjustable control rod for the servo arm /swash plate on my BR6508 helicopter. By making the control rod adjustable allows the swash plate to be easily fine tuned to a proper alignment. By adjusting the control rod/swash plate I was able to put more forward moving speed back into my helicopter and no longer needed to use the extra 1.25 ounces weight in the nose of the helicopter. In the near future Iíll do a post (with photo) on how I made the adjustable control rod for the BR6508 helicopter.
8. Using a larger mah Li-Po battery on the BR6508 helicopter not only gives the helicopter longer flight time, but also boosts the takeoff/climb speed of the helicopter.
Recently on my BR6508 helicopter I also started using a 2800mah Li-Po battery (with a 35C rating) and the flight times have increased to over 7 Ĺ minutes (with lights and camera on). The large Mah battery has also boosted my BR6508 helicopterís takeoff and climb speed even faster than it already was (The BR6508 can do really fast takeoffs for its size).
Even though the 2800mah battery that Iím using is about 1.3 ounces heavier than the stock battery, the larger Li-Po battery really works great on the BR6508 helicopter since it increases the flight time of the helicopter, boosts the takeoff/climb speed of the helicopter, and the higher C rating battery runs a lot more cooler than the stock battery. The higher C rated battery handles nonstop flights with no problem (even after a 7 Ĺ minute nonstop flight the battery is only getting warm at that time).
Also, I wanted to mention too that the 2800mah battery fit right into my BR6508 helicopterís battery compartment with lots of room to spare (and without any compartment modification and without any balance adjustments). On my helicopter the way I secure the 2800mah battery to the inside of the battery compartment was I put a strip of Velcro on the bottom end of the battery and put a strip of Velcro across the top edge of the front cross member (of the landing skids) at the entrance of the battery compartment. I did it this way on my helicopter since it gives easy direct finger access to the Velcro so that the battery can be easily separated from the Velcro and removed from the helicopter, and since no modifications were made to the battery compartment the original battery can still be used just as before.

I see that my BR6508 post is starting to generate lots of interest, including non-coaxial flyers - 229 views and growing.
Below is a photo of my BR6508 helicopter flying in a little breezy air.
you have put a lot of effort into documenting this for the benefit of anyone who has one of these. Well done. If something like this was done for each heli it would be an amazing resource.
It's obvious you really get a lot of enjoyment from it and that's what matters the most in a hobby.
I haven't actually read anything about them previously so don't know how popular they are, but anyone who does have one should find t easily with a google search. Hope you continue to get more folks viewing the thread.
By the way, disregard the derogatory comment from the resident troll who contributes nothing to the forum.
Nice writeup. I did notice that you say you fly until "the helicopter’s power starts to fade quickly requiring more and more throttle to stay up". I just want to caution you that LiPO batteries do not handle complete discharge well. Unlike NiMH and NiCd batteries, you can't fully discharge LiPO batteries without damaging them. The general rule is to only use 80% of the battery's capacity, i.e; on a 2200 mAh LiPo you can safely use 1760 mAh without damage. The best thing you can do is to time your flights, but if you can't , at least plan to land at the first sign of power loss. Your batteries will last much longer if you do. If you decide to continue in this hobby, a good balance charger that will tell you the mAh put back in the battery is a must.
Above all, have fun and happy flying!!

Hi Everyone, (Also thanks to Mono and norcalheli above for their helpful input).
I have posted a couple photos below of my BR6508ís video camera and how small it is. The actual size of the camera itself located inside the plastic housing is only about 1/3 of the actual housing size, most of the plastic housing is so that the camera can be mounted to the helicopter and for making the lenses view angle adjustable.
The camera itself works great and takes pretty good videos when considering its size and its apparently a new design of camera.
The BR6508 camera is pretty unique looking and I thought I would post pictures of it so others can see what it looks like.

Just some notations;
about the BoRong Camera. I was unable to find any way to have the device record the actual date and time. Each picture or video is recorded as 09/08/13 and around 1:00am+, with time varied to 2:am+.
It must be a driver issue.
I notice that the limiter stops on the rotors prevent blade strikes, but also, in a crash they help transmit a lot of torque down the rotor shafts allowing things to get broken internally. I don't have much flight time, but have a lot of crash /repair time. I have 2 of those little Syma S107 heli's and notice that they don't have the limiters, so blades swing free. I've crashed that thing countless times with no damage ever. So, I'm guessing it's a design preference.
Yes, the BoRong can really haul the mail. Very powerful on take off. I really like mine, even though so far iv'e spent more time repairing it than flying it, all do to my own inexperience.
Mine was damaged upon receipt, but I had no idea what I was looking at so was trying to fly it with damaged parts. It's a good idea to check photos of new ones to compare how things are supposed to look.
Ray, does the 2800 battery connector match up with the stock one on the BoRong?
I for one, would be very interested in seeing a picture of your adjustable linkage. My Heli does the same thing, drifting backward.
I now have a safety device attached to my Transmitter, to prevent accidental Spool-ups.

Ok, so a couple nights ago, around midnight, thought I'd check the linkage on my 4 ft long Electric RC helicopter.
It was on my desk and I had the cowling off. Just got out of the shower and I was tired. So I turned on the Controller and the heli and watched the linkage go up and down as I worked the controls.
It looked like I was going to have to remove a control arm on the heli and it would take a long screwdriver to do it.
So I reached across the desk for the desk for the screw driver and accidently hit the throttle lever into the Full Power position.
Needless to say the Heli took off immediately, SMASH!! right into the ceiling and there it stayed, hovering up against the ceiling, while I was in Shocked/Amazed mode. The rotors span well over 2 feet so i didn't
want to lose any important body parts. I jumped up out of my chair, grabbed the landing struts and pulled it down off the ceiling.
I was finally able to reach around to the other side of the heli and turn off the switch.
Now there is a safety device installed on the throttle, a very large rubber band, holding the throttle down.

A notation on Trim Buttons for the Bo Rong BR6508;
# of Beeps per trim Button
Aft < ==== 11 Center 11 ==== > Foreward
Sideways Left < ==== 11 Center 11 ==== > Sideways Right
Turn Rotation Left < ==== 62 Center 62 ==== > Turn Rotation Right
At times I have counted 12 beeps instead of 11, OR 61 Beeps in stead of 62.
Sure wish I had known this when I first got it.

Welcome to the forum and thread
In your first post above (the question bout the BR6508 video camera being able to record with an imbedded date and time), I too have found that the BR6508 video camera doesn’t record with an actual date and time on the videos. I could be wrong, but I was thinking maybe it can’t be done since the camera itself doesn’t have a self contained internal battery.
I think I have found the year and time thing that you were describing by right clicking on a downloaded video file and left clicking on properties, but the created and access dates on my video properties are similarly incorrect, but the dates are different than yours with the same variable 1 am to 2 am time. I could be wrong, but I think those dates and times are just to show when the video file was created onto the computer. But then again they are showing a wrong date. I have been unable to find a way to correct them though and generally just type a date in on the file when downloading the videos.
So far the only time I have come across is the play back time (length of video) when playing the video back on my Microsoft media player.
Of course though, having an actual imbedded time and date on the videos would really be a nice to option to have in the BR6508 camera software.
About the battery I’m using, it's a 35C Lion Power battery (bought it on eBay) and it came equipped with a Deans connector (the same type as the BR6508 battery connectors), so it will plug right into the BR6508 connector. The 2800 mah battery gave my BR6508 an even more powerful, faster takeoff/climb speed, the battery runs a lot cooler (just warm after 7 minutes of flying), and also gives my helicopter over 2 minutes more of flying time before its down to 11.1 volts.
When considering an aftermarket battery for the BR6508, I would recommend buying one with a 35C continuous rating or higher so as to help hold battery heat down (a cooler running battery will help to extend battery life).
About the limiters on the main blades, I personally haven’t had any reliability issues with the restricted swing back of the main blades.
I have found though that the BR6508’s geared rotor system is very tough (heavy duty and well built) and can with stand a lot of crash force. For the most part, as long as the helicopter’s rotors isn’t running into a solid object with lots of power applied, the BR6508 rotor system seems to be able to with stand a considerable amount of impact.
I now have over 100 flights on my BR6508 helicopter, and so far luckily my BR6508 hasn’t suffered from any bent shafts, stripped gears, gear wear, or broken blades (the blades are very strong, also very dent resistant).
The lower blade pivot pin (on the hub) is the only part I‘ve broken so far, I broke one of those when trying to land on too steep of a hill, and the helicopter rolled down the hill several times.
I must say though for me personally I have owned 3 or 4 other helicopters, and in my case the BR6508 helicopter is by far my most durable, reliable helicopter I’ve ever owned.
About the throttle; Always be really careful and only turn the helicopter’s power on when your 100 percent sure that the throttle is set to the off position on the transmitter.
I’ve never had a problem with an accidental throttle up, but I can see were it could easily happen. Once the transmitter trim is centered I always turned my helicopter's power off whenever I was going to adjust the servo's control rod or the arm on the servo, but your rubber band idea is a good extra step preventive measure.
About adjusting the servo arm (lever), I have found that repositioning the servo arm will help the drift back, but only works some what good since it will limit’s the servo arm movement for making maximum forward speed.
An adjustable control rod works much better and eliminates drift back on takeoff and helps to maximize the helicopter’s forward speed. I will post a photo of the adjustable ones I made soon.
By the way, excellent information about number of beeps on the transmitter. I haven’t counted them on my transmitter, but that information will be helpful to BR6508 flyers when testing or adjusting the trim on a BR6508 transmitter though.

Great information. I have this whole thread in a Word Doc. I will be ordering one of those batteries ASAP. Pretty sure I degraded mine. A couple times I thought I was supposed to run it down before charging and that doesn't appear to have worked well.
Just recently having trouble getting off the ground and flying time is down to about 2 mins.
Just another notation.
Measured Battery Volts after flying: 11.05v
Measured Battery Volts after charging: 12.32v
When I got a new servo arm, noticed the holes were too tiny for the linkage rod, so I used a tiny flat-head jewelers screwdriver to drill it out, since I don't have a drill bit that small. That worked ok.
Yes, I can vouch for the durability. One of my first flights , unaware of shipping (or pre-owner)damage, the heli struck a tree top about 100 ft up. That was a nose dive smash and the heli should have been beyond repair. But with only some parts damaged, I fixed it.
Thanks again for the info. Looking forward to your linkage mod.
