X-3D Brushless Quadrocopter, general quadrocopter, x-ufo discussion PART 2

With the Poll - X-3D Brushless Quadrocopter, general quadrocopter, x-ufo discussion hitting over 2,500+ posts ... I think it is time to split the thread group again ...

Part 1 showcased the X-3D Brushless Quadrocopter and this thread should continue on as a support thread of discussion . See below for the recap.

There is a planned successor to the X-3D gyro board to be available soon ... info here ... http://www.asctec.de/main/index.php?...g=en&cat=hobby

Some interested parties have asked "how much soldering is involved with this kit"?

The power taps for 11V and 5V were soldered to the X-Base at +5/+11V and FET #1 and #2 locs ... all have connection holes along the rim of the board to solder to.

The LED mods were also soldered to the X-Base ... two wires X 4; The LED strips were also soldered together to one connector

then 4 X-BLDC communication wires plugged into each esc to the X-Base;

all electronic components are pre-populated on surface mount boards ... all boards plug in ... X-3D gyro board & X-ACC accelerometer add-on.

All programming is done via USB comm cable to a computer running X-Control software.

The X-Base solder points are small so a magnifier helps.
Some interested parties have asked if this particular quadro can be used for Aerial Video Photography ...

This quadro is designed to be more of a Ferrari in fun flight performance.
Answers to most general questions can be found in the previous threads ... I compiled a collection of links here ...

The new craft is no longer a toy but a professional flying machine. It uses four brushless outrunners motors (called X-BL) which are connected to the high-performance brushless controllers (called X-BLDC) which where developed for the needs of a multi-rotor system. Due to the high speed attitude controller running at 1kHz and the very good power to thrust ratio of about 4:1 the X-BL is a perfect trainer for acrobatic helicopter flying. It shares the advantages of the mechanical simplicity and robustness with all other quadro-, and multicopters. No complex swashplate and head assembly to worry about. Here are some pics of the completed X-BL Quadrocopter (with beta X-BL motors ... the current X-BL motors are mono-tone color and more powerful)




It is currently sold as a DIY Kit Project where the key components of the X-3D Gyro Board, X-Base Main Board, X-BL Brushless controller and motor kit, X-CSM Frame, X-Propellers, USB Interface, Tx and Rx will be available separately. This DIY Project will require some minor soldering of the X-BL, Rx, power connector, and LEDs to the X-Base Main Board. With the flexibility of supporting different Receivers, any 6-channel Transmitter or higher can be used to control it.

Quadrocopters operate on the principle of using two pairs of counter rotating fixed propellers. Controlling the rpms of each individual motor by a microcomputer allows for ascend/descend, turn right/left, tilt forward/back, or roll left/right flight characteristics. In that respect, it is a little easier to fly than a conventional RC helicopter.

Features
Sensors
X-3D and X-Base use a three axis acceleration sensor (X-ACC) as absolute angle reference in pitch and roll
Compatibility
The well known X-3D heading hold mode remains fully functional. Loops, rolls in any combination and all tricks are still possible. Your user defined settings are still compatible! The Ext1 function (which can be trained in with the X-Base e.g. on channel 5) is used to switch to the X-ACC mode during flight.
Precision
The X-ACC mode estimates the absolute pitch and roll angle with an ultra fast data fusion. The RC sticks set the absolute angle!
Put the sticks in the middle and the UFO will come back to a horizontal level within the measurement precision. The X-ACC mode is perfect for very precise indoor flights and for beginners to get in touch with flying a UFO.
Dynamic
The unique three axis compensation enables the X-ACC UFO to fly highly dynamic maneuvers with excellent precision and gives a safe start for dynamic 2D aerobatic flights.
Safety
Close or far away: The X-ACC ensures that the UFO is always controllable. This is increasing the safe maximum flight distance. In case of an reception loss the UFO comes back to the horizontal level and descends slowly.
Future investment All potentially upcoming X-Base upgrades will be able to use the X-ACC as well.
Compatibility The X-ACC works with brushed motors as well as in brushless UFOs.

Note: Can be used to stabilize for Areal Video/Photography Platform

First X-ACC impressions here ... http://www.rcgroups.com/forums/showp...postcount=1315

Receiver Options

Option 1 (recommended method)
X-ACT 35MHz, 40MHz, and 72MHz (72MHz Receiver will be available ???)

- DSL protocol one simple plug in cable mating with the X-Base
- Programmable functions through the X-Base
- Designed and modified for the X-BL
- Calibration done via X-Base with X-Control PC software

Option 2
PPM Receiver

- Freedom to use any receiver with special downloadable firmware version.
- Any 4 channel PPM receiver may modified to work with the X-Base
- 3 wire connection soldered to through hole pads on X-Base (Power, Ground and PPM serial signal)
- Up to 8 channels decoded from PPM serial signal from any 4 channel receiver
- Corresponding matching Rx/Tx Crystal

Note: Many using the Berg 4L mini 4 channel receiver procedures follow link
http://www.rcgroups.com/forums/showp...&postcount=140 and http://www.rcgroups.com/forums/showp...&postcount=137
and mine here http://www.rcgroups.com/forums/showp...&postcount=582 ... I kept the pins in place to be able to use the extra 5V power/ground pins for other things like LEDs and CAM.

NOTE: If you remove the pin pads, you can introduce more problems on the board traces.

Transmitter Options
- Any PPM Supported Professional Transmitter will work using ACRO standard settings
- Recommended 6-channels or greater (Some folks are operating minimally with 4-channels)

Misc Details
Additional things needed to get the X-3D Brushless Quadrocopter off the ground

It definably feels allot more stable and responsive and the sound of the props minus the brushed gears is awesome. Even with the quick stock frame mod it came out the hole level and strait.. I dont really see a dramatic power increase tho, or it seems it doesn't accelerate that much faster. I hope this is because its been in acc mod. Or maybe even a dying lipo pack, Iv been using the same one since day 1 and its starting to get a little puffy. Ill change up the acc1 to hh1 and see what results that gives. I noticed this with the brushed motors allso, Cant remember if it i noticed it befor or after the installation of the acc board.▲▲

Congrats ... that is great news! ... now we know that the united hobby hacker motors work ... you should be seeing a 3-4x power difference when you start playing with payloads ... X-ACC mode does add a little bit of a drag when flying around since it is compensating for self-leveling ... please post some pics ... btw, what did you end up doing for the X-BLDC to X-Base communication cables?

Thank you I used the data cables from digi-key, they were about a half inch shorter than the one that came from the shop but they seem to work fine. the wires snap into the connectors easly no cremping needed.
All so, one of the motors doesnt spin as freely as the other 3. Not sure what to make of it. Doesnt seem to affect the controll of the quad, but im wondering if that mite have something to do with the acceleration drag i think i got. Maybe the controllors make the motors rev up only as fast as its slowest motor to maintain controll? I got a new spar. I may swap it out.
Ill post some pics tomarrow. Thxs for all the help guys, I like it!

The X-Base uses what's called DTC (Dynamic Thrust Control) which essentially limits your power output to all motors in effort to match the limits of the weakest motor in the bunch. This is what makes flight more stable than the Chinese mobo, but also you suffer a performance penalty if one of your motors is underachieving. There is a good chance this is what you are experiencing, as you should see a sizable increase in power going from brushed to brushless.

One other thing to make note of is that I definitely noticed that it took more stick to get get into the air than with the brushed setup. This was because the brushless software was made with a linear throttle curve whereas the brushed version used a parabolic curve making it seem as if it took off with less power. On the high end of the stick however, you should see a sizable difference in static thrust skewed towards the brushless setup. With the brushed software, you'd get quicker response off the line, but the top end was much weaker.

The sound of the BL is awesome, isn't it?

@Chessman21 ... this is really very good news ...can't wait for the photos showing how you modified your frame to accommodate the motors ...

@saturnine .... DTC Dynamic Thrust Control .... this is way cool... if I knew this from the beginning I would have switched to the X-base from day 1 .. it would have added few hours to the lifespan of my 1st set of brushed motors

Thanks

Khaled,
My recommendations that have worked well for me:
1. Load the X3d [*.ufc] firmware first (it can be attached to the x-base or not at this point) After removing the bootloader pin and rebooting, load the parameters [*.ini] that you desire in each 1-4 window (i.e., beginner or VACC, or advanced, etc.; if you have an ACC module, then make sure the ACC parameters are in the ACC 2 and 4 positions, Hint: the ACC parms will have an PITCH/ROLL/height_d angle of "0") note: The gyro data stream on an x3d loaded with xbase firmware will not work unless the x3d is mounted on the xbase and power is on.
2. Load the X-Base firmware [*.xbs]. After flashing the firmware, remove the bootloader pin from the xbase and reboot. Then cal your TX and ACC if you have one. Check the motors for the proper position on the arms and that they are turning in the proper direction. Adjust by dragging from the right window to the arms of the graphic if required. The first time you drag to arms that have ESC's assigned, it will clear two arms. Then drag it again to the proper arm and both cleared arms will be filled with the correct ESC address.
3. Load the XBL firmware if required [*.blc]. Make sure you don't have the boot loader jumper on the X-base or X-3d when doing the XBL firmware (ESC) flashing. Be sure to select all on the left window that you want to reload. This can be finicky. If it can not find the motors/ESC's when you first do the search, first close the X-control app, then cycle the power off/on on the quad, and try again. If it still can't find them, remove 3 of the four black/blue I2c wires and cycle power back to on and try again. If you load the "music" you may or may not get a "finished" prompt. It loads these very quickly, so just cycle power on the quad and you will see that it has flashed the music anyway.

Note: The X-Control is "usually" pretty good about telling you what to do next, or what the problem is. Make sure you read it closely when you do an action and do read the processor response window at the bottom. The common mistake most folks make is to forget to click the correct tab when doing a firmware or parameter update. Not clicking on the proper tab will get you the "not connected" or "can't find" response. Just click on the right tab and you will be back in business
Hope that helps!
Cheers,
Jim

Heres a few pics, I havent done any agressive flying, this is basicaly just a tester, the motor is bolted onto a plate thats "hot glued" to the stock motor holder seems to hold but i dont trust it !00%, I dremeled the suport shafts off the props and hot glued them inplace to catch the 2 of the four grooves that are made onto the rear shaft adaptor that came with the motors. And why are we waiting for new or beter software for the acc/bl config? Whats it not doing now that it could do? Seems like it flys like the brushed acc setup to me.

Is there any way to bolt the plate to the stock motor holders too? ... the vibration generated by the motors could cause the hot glue to wear over time.

Looks like a good mod ... but switching from brushed to brushless, you should be noticing more power than you are seeing ... was thinking of using something (maybe CF plate) like that to extend the distance on the X-CSM arms to accommodate the bigger Hacker style 20-22Ls and larger 10X4.5" props.

moti is using those hackers on his brushless DF ... http://www.rcgroups.com/forums/showp...postcount=1418

Yea i think i can get a bolt/nut were the stock motor gear sticks out, im gonna work on that and maybe a thin strip of gorilla tape around the power wires just behind the motors just incase they come off so it doesn't put any stress on the esc boards.

Question: About this 3-4 times the power, i changed out the motor that didn't spin as freely as the others and I didn't really tell a differ in the acceleration. My battery pack is a 1050mah "12c continuous 20c in short burst" and i have hh1 loaded with the "beginner" setting. Think either one of these scenarios may be the reason i don't see the dramatic power increase?
