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).

I can't verify it works because the connection to mission planner is unstable.
USB connection timeout (with or without external power), and a telemetry radio connection (with external power) stops retrieving params at "get compass3_offset_y "
The ESCs did not initialize. The safety switch light stopped flashing after a short time.
Without mission planner I can't diagnose it any further or complete the setup.
Thank you for your efforts I'll try Ardupilot Copter on the pixracer when the bugs have been ironed out. I wouldn't feel safe flying a large hexacopter with the dev version of AC on pixracer.
Luckily I have 6x APM's and 3 other pixhawks to fly in other models while I wait :-)
Hi Michael,
That sounds like a bug I pushed a fix for just before I pushed the fix for the Hexacopter.
I can understand not wanting to fly the dev version on a large vehicle. Perhaps you could try it with props off at some point just to let us know if it is behaving correctly?
Cheers, Tridge
Hi Tridge, I tried AC3.4-dev (4529028c) and AC3.4-dev built 20160513 07:41 they both work on a hexacopter.All motors run as expected.
Telemetry was stable (USB and radio) and the safety switch functioned as expected.
The current issue is compass calibration. The pixracer found 3x compasses and numerous compass calibration attempts couldn't reach a concensus. My preferred method, the office chair method, produces quite good torroids around the cardinal axes albeit at different scales and offsets.
I'm looking foreward to AC 3.4 when it goes gold.
Thank you for your efforts. Good luck with OBC 2016.
Hi Andrew, Could you please notify here when the issues will be fixed. I have the same problems with ESC not starting and no COM link after few seconds.
I will be more than happy to test it on the bench. I am not confident flying my drone with this version ether and I am too unfortunate to get broken dev versions every time I try to test them. So far PX4 beta is working for me, but I am more familiar with MP and APM and hope that it will work eventually.
Thanks!
I will try AC again in about a week with props off. I am really keen to fly this hex, it has been a 6 month project and the recent weather has been conspiring to prevent a full test flight.
Thanks for your efforts. It is appreciated.
I've noticed that if using class 4 SD card and enabling full logging, the board works until the first reboot. after a power cycle the board won't boot. the same card works great with a pixhawk and full logging enabled, it also works fine with pixracer and the default log bitmask value. Changing SD card to class 10 fixes the issue.
Thanks for the suggestion. I haven't changed the logging detail. But I am running a class4 card. I'll get a class10 to eliminate that as a possible problem.
Thank you so much. I really appreciate it.
Is it just a matter of setting:
RC5_PARAMETERS - RC5_FUNCTION to 37 (motor 5)
RC6_PARAMETERS - RC6_FUNCTION to 38 (motor 6)
and the - RC_MIN / RC_MAX PWM values?
or is there more config required to describe how many motors are on the vehicle?
+100 on that! About half a year ago I suggester starting to work on DJI canhub support, so we could use DJI gimbals with pixhawks... It shouldn't be too hard, partially because there are a few libraries with DJI CAN...
