First of all, my X-UAV Clouds (Pixhawk 1), Volantex ASW28 (Matek F405 Wing) and Mini Skywalker (F4 pro bus) fly well with AP 3.9.2 stable.
With a SkyEye from HK, I have flown with Arduplane more then 150 times. Last flights with a 3,9,2 beta version without problems, the crash flight yesterday then with 3.9.2 stable:
I have no idea why the Pixhawk after a short time did not respond to any inputs in FBWA. Only remarkable: very windy and after booting the plane was rocking for several minutes on the ground in the wind until arming. On impact SD card jumped out. However, datas were recorded until shortly before the impact. Unfortunately, I did not switch to manual mode in time. Compared to other flights, I’ve only noticed the difference between the different pitch parameters (AHR2.Pitch / ATT.Pitch) so far.
Faulty ATT.Pitch in FBWA causes the crash ?
@Tridge: Can that be the reason for the failure?
