This is a discussion to focus the feedback and support of ardupilot on the PixRacer board from AUAV.co.
We believe that all teething problems encountered are now resolved and so we recommend people load Copter-3.3.4 which is available for all multicopters through the Mission Planner's (and other GCS's) Install Firmware screens. Note that because regular Pixhawks are still on Copter-3.3.3 the install icon may show Copter-3.3.3 but rest assured, Copter-3.3.4 will be installed (you can check the version by looking at the very top of the Mission Planner).

A lot of test today with pixracer...
My motors (emax 2205RS) doesn't react well. My little quad is unflyable.
Trying to adjust pitch/roll PID, no effect at all. Seems better by increasing INS_GYRO_FILTER (20 -> 120 )
Better but still unflyable.
I will try to remove oneshot125 and I will make a test.
Change oneshot125 (=2) to oneshot (=1), no diffrence. My 210 still oscillates...
I have increased setting PWM output dither to highest in my esc, no difference.
Tried to change a lot PID parameters but still the same..., it can't take off :(
Anyone can help me?
Thanks
Arducopter 3.4 RC1
In my opinion you did a wrong Esc calibration .
Try to calibrate Esc by single one manually by the radio receiver.
Hi,
I've tried 3 ways to calibrate my esc:
- First in oneshot125 (parameter in pixhawk =2) : calibration just don't work with 3.4RC1
- Second : directly in BHELI , ok it works
- Third in oneshot (parameter in pixhawk =1), ok it works
With "damped light' mode : Simply don't fly, too many wobble... with a lot time passed to set PIDs...
Without "damped light' mode : I can take off, but it's like a big boat with a lot time passed to set PIDs...
My conf:
Frame : 210 mm
Esc : DYS 30A , Bheli 14.6
Motors : RS2205 emax 2300kv
Props : DAL v2 5x4x3
Pixracer : original mounted on damper
Firmware : 3.4 RC1

What are your PIDs? For smaller quads you really have to turn the default PIDs right down, trying dividing them all by 2, if that's not enough then by 4. You may have to edit the parameters directly to bypass the minimum's set in the tuning screens.
Hello,
I have tried many combinaison : at first P= 0.08, I = 0.1 D=0.004, unflyable to many wobble
And now P=0.01 , I = 0.05 and D = 0.003 , these paramaters allow me to take off... but just take off, after it's like a boat ... and crash. :-/
It's not my first copter, (2 on arducopter, 1 on cleanflight, 1 on openpilot, 1 on betaflight), but it's first unsetable... 3 hours of settings on pixracer :-/

It's a little out of date for 3.4 but really, really good read from the righteous dude that wrote most of the control code for arducopter.
Thanks :)
