Hey all,
Have my first setup planned out, but haven't flown FPV before and i wanted to be sure i have everything i need, so i thought i'd post my list.
I'm pretty good at LOS and i've flown a sim for a while

Diatone gt-m3 - figured i could lower the rates a bit until i feel confident on it

spektrum dx6 - already have it

longbow mini dsm receiver - only one i've found that fits, if anyone has a recommendation for a longer range receiver that fits i would love to hear it!

Eachine VR D2 Pro goggles - on sale right now, any recommendations for boosting range with vtx?

850 maH 3s and 4s battery - what do i charge these with?

The Patch Antenna For DJI Cendence Remote Controller

Since receiving the DJI Cendence I have seen the question time and time again asking is it worth using the DJI Patch antenna compared to the standard omnidirectional sticks and what benefit does the patch antenna give. Because of this I decided to do some tests to try and show the difference between them and see what was one was actually better to use as well as get some data on how directive the patch is as well.

For more info on the Cendence remote or the Inspire 2 or to order see
DJI Cendence http://click.dji.com/ABwjVqd-Sl9O9-w...0012&pm=custom

A Closer Look at the Patch

As you can see the patch is not just a simple passive antenna, while it has 2 RF connection it also is connected to the CAN port on the Cendence remote, because of this something to note is that the patch antenna also has firmware onboard and its important you update it when you update the remote, this is easily done by connecting the antenna to the remote before you update via DJI Go 4 or the Pilot App.

Looking inside the antenna it’s self you will find there are 2 identical PCB antennas, these are backed by a screening sheet with the logic controller board mounted in the middle. its important to ensure you have the antenna facing the correct direction as this screening sheet at the rear will block all signal from getting through so the antenna should be mounted with the smooth flat face pointing forward

Just finished my 1/4 scale, 1933 Pietenpol Aircamper. It started as a vintage, House of Balsa "in the bones" project that I got from my good friend Billy. I saw a lot of potential in it, so I decided to take on the challenge of finishing it. I covered it in Ceconite, pinked & stitched it all (with Poly Brush), and filled the weave with water based Polyurethane. I then finished it all off with Rustoleum rattle cans. I've got a OS Max .91 four stroke hiding under that balsa 4 banger! The air for cooling flows through the "fake" oil cooler mounted on the front of the "engine" & out through the empty rear of it. Here's some pics:

In case you were wondering where I came up with those cool little "spark plugs"...........there just wood dowels, turned down on my lathe, painted white, striped, laying a brush down against the white while turning in my lathe, all in with a drilled out lock nut, finished off with a miniature brass stud & nut. Pretty convincing, huh? Building the "woody" 4 banger was actually more fun than the plane!...Continue Reading

First quick test and edit of my first video footage of the super fast XJB 145 flying around a bike track and filmed with a Quelima SQ12 HD Camera. I am sure I didn't get to 100mph but it sure did feel like it! Boy, this drone is fast and definitely an upgrade from the ViFly R130.

💨 100 MPH 💨 Quelima HD Camera Bike Trail Speed Test with XJB 145 drone under 250 grams (Adobe Edit) (2 min 5 sec)

The Quelima SQ12 HD footage is not bad for 30fps although there are some dropped frames and a black sun due to the cheap processor but for £10 it's not a bad camera.

I think the XJB 145 deserves a runcam split mini but the frame may need to be changed first. The Quelima SQ13 and Hawkeye Firefly are in the same category as the SQ12 so they are not worth the extra bucks in my opinion.

Music: Mixes by Gramatix

Equipment used: HGLRC XJB 145 Drone under 250 grams https://www.banggood.com/HGLRC-XJB-14...
Quelima SQ12 HD Camera (like the Hawkeye FireFly Micro Camera) https://www.gearbest.com/automobiles-... (the Quelima SQ13 like the FireFly is out now on GearBest
Jumper T8SG https://www.gearbest.com/radios-recei... Original SQ12 footage modified using Adobe Premier Pro editor Betaflight 3.2

How to update or remove the date/time stamp on the Quelima SQ12: The camera will write a text-file to the sd card (20150101235530 / yyyymmddhhmmss) that can be corrected with a text editor. If you don't want the date timestamp to appear on your video simply change 'Y' to 'N' (No) and save to sd card.

The new S1 Pentium from JJRC is one of the mini self righting boats in their S series which includes three very affordable 14 inch boats of different styles. The S1 is currently available for only $36.99 Click me to order.

The Pentium with its red, and white color scheme, immediately jumped out at me as a great looking little boat for running in pools, ponds, and other small bodies of water.

These little water cooled boats are powered by a 370 motor, and a 7.4v 600mah LiIo battery. They have fully digital proportional throttle, and steering, and the steering duties are handled by a micro 3 wire servo. As the title suggests these boats are also self righting, so there is no need to rescue a capsized vessel. Simply apply a quick blip of forward to reverse throttle, and the boat will roll itself upright, ready for more action.

All three models, S1, S2, and S3 are complete ready to run packages, that include everything needed to run your boat, except for 4 AA batteries for the radio transmitter. For safety, these boats also feature a low battery warning beep, and a weak signal warning beep that sends the warning back to the radio so that you know when you're getting out of range, or the battery is getting low.

Check out the pictures, and videos. Please don't hesitate to ask any questions. Stay tuned for running video coming soon.

Happy Boating!!

First run

Hello & Good Day to All!

I badly need your help how to trace the problem in my power supply HP ESP135 Model: PS-3601-1C. The status is like totally dead but the 2 power capacitors are getting voltage of 300VDC. Shorting the output pins 6,8,10 in this case does not help.

Anybody has a good knowledge about this power supply? I need the Schematic Diagram please?

Thank You and Best Regards,

Picked up a cheap 250 CFX that needed a bit of a going through. Motor had tired bearings and squealed like hell in idle up and several other little gremlins tweaked feathering shaft, slight tweak in the tail tube and sloppy feathering shaft bushes. Chassis / servos / canopy all mint.

Motor - ran okay just sounded terrible in idle up, had a high pitched squeal out it went, pulled it down and yup both bearings notchy as hell and showing signs of wear on the shaft - time for a replacement.

In with a Turnigy 2627 - 4200kv. went up one size on the pinion - 13t to counter the minor drop in Kv value 4500/4200 x 12t = 13t and went with a steel lynx gear - nice. The Turnigy motor comes in a nice plastic case with plug ends, shrink-wrap and a spare main shaft and a couple of 0.5M pinions - 11 and 9t.


Initial run up was nice, then down the park and the main motor esc gave up....... this is the third blade 2 in 1 I've had smoke the main motor circuit, had a 200 SRX go, then my 230S went out and now this one in the 250 CFX. No warning fine one minute - stop the next and the ESC is smoking hot......... I'm figuring they are crappola quality wise in the main motor circuit components........

Another aspect I really hate in the 230 and the 250 is the mule kick these esc give on start up. this is why so many people have hassles with these things tipping over on spool up.......... I did my own 2 esc...Continue Reading

The next round was simply a race around two pylons. Phillipe's model was fitted with a LiPo the size of a young house-brick and he proceeded to win his round. He said that it was just a question getting into a rhythm. I fitted a 2200 4S LiPo to my model and took off, waited for the MC to announce the start of the round and opened the taps. The model shot forward overtaking many of my competitors. Funnily enough a three-channel trainer is more difficult to fly accurately at high speed than a four channel model because it's constantly trying to correct itself. On one circuit it went into all sorts of unwanted gyrations leading to a cry of "Oh la!" from the judge standing behind me, but I recovered it and got into Phillippe's rhythm, turn, slight opposite rudder, level wings, turn, slight opposite rudder etc etc. The Contest Director announced over the PA that we had one minute to go. I don't know whether I was winning but I was not aware of many models getting past me but suddenly my model slowed. I called a landing, "Pas d'electricité!" and put the model down on the runway. My judge told me that I had passed 23 pylons in four minutes. An expert with a really fast model can pass 40 or more pylons in the five minutes alloted to the round but I am no expert, however, I was quite pleased with Boris's performance.

I knew beforehand that each round of La Coupe Des Barons lasted for five minutes and I knew that I could get eight to ten minutes out of my...Continue Reading

-I tuned my Saito FA-56 with a Xoar 13x4 wood prop. I would have used the 12x6 but i nicked it with the tacho ...lol dumb

I may post the retarded .56 video but i yapped too much. So i included a lackluster picture in this here high-energy blog

Also, i got the .56 down to a reliable 2300rpm idle yesterday. Not bad.
So now i need to make a better video!

-I learned how to do the backflip start. You may want to try it if conventional flip starting gets tiresome. After priming for 2-3 revolutions, it seems to work on the .56

-I just got an FA-62 but work was NUTZ today otherwise i would have run it.

Right now i am sitting on my wishing it was not dark

Tuning up the Valiant on the porch, gluing this twisting that with my little guy, wife inside watching whatever wives watch when in possession of remote.

Big ass bee emerges from house crevice.

Minding his own business but a bit too close for comfort. Maybe a friendly, maybe a hornet, don't know my insects, have to engage.

Not looking forward to clapping this mother to death, that's a lot of bee goo, but bee is armed, hovering menacingly on private property uninvited.

That's a bad move in the Constitution State, bee.

Tell wife to get the boy inside, wife shuts the door, they stare through glass as I draw my seaplane with one hand, set the throttle mix to insecticide rates with the other hand, aim toward bee's vicinity, and,...

Foooop! 330W vacuum guillotine at a 7 inch pitch restores peace to the porch.

Engage throttle cut switch, locate and collect bee debris for photo, give baby and lady the all clear.

Bee squeezed out a few transmortem shakes, decapitation wounds prove fatal. Debrief wife who concedes "that was cool."

Quickly explain death to three year old, son offers Mister Bee posthumous apology followed by an improvised at-sea burial. Flush lever pulled by child, "Byebye Mister Bee!" as bee swirls down into the great unknown.

Judge that boy exhibits appropriate amount of empathy for bee, no red flags, top off episode with a tall cool Budweiser.

This is the Unboxing, Build, Gameplay Demo, and Review for the new HEXBUG Robotic Soccer Arena. This kit allows you to duplicate FIFA World Cup Soccer action with RC Robots following your commands.

HEXBUG Robotic Soccer Arena Unboxing, Build, Gameplay Demo, and Review (9 min 19 sec)

Here are the review notes for this International Soccer simulator:

- The set comes with two great looking HEXBUG Soccer Bots and radios, including the batteries for both of them.
- The HEXBUG Soccer Arena looks great and goes together easy.
- Each Robotic Soccer Player is quick and nimble, very similar to the HEXBUG BattleBots kits I have reviewed recently. They most closely move like HEXBUG versions of BattleBots Tombstone & BattleBots Minotaur.
- The HEXBUG Robotics kick action is strong and predictable.
- Both HEXBUG Soccer Players are customizable so you can set up any World Cup Matches you desire.
- The magnetic soccer ball acts a lot like a real one.
- Up to four players can join the fun at a time.
- You do not need to be an RC expert to enjoy these toys. The learning curve is short and they are still fun as you get a feel for how they work.
- The small radio was surprisingly easy to use for its size.
- Kids of all ages can enjoy it, even big kids like me!

- The infrared radio range is limited and you must point the radio at the HEXBUG Robot Soccer Player for them to work properly.
