Hello to all,
I would appreciate your help with this weird crash we had with a Bormatec Maja plane with arduplane 3.7.1 in a Pixhawk.
We checked everything before take off, and launched the plane in FbwA. The aileron control did nothing and plane flew in a very large radius circle and we couldn't change cruise. Then we switched to RTL, the plane gained altitute as expected but it flew away from home, still in the same large radius circle. In RTL mode, however, a slight movement of the roll joystick produced a sharp turn, like a very sensitive "nudge". Throttle control was also weird, with constant changes of throtle, it finally crashed.
Looking at the logs, it seems that navROLL in telemetry logs and desROLL in datasflash roll are always zero (exact zero), even when trying desesperately to steer the plane in FbwA. After the crash, the ailerons moved ok with the transmitter joystick in manual mode, but did not move at all in FbwA.Any help to understand what happened will be very much appreciated. We have tried to fly this plane three times, everytime it crashed in a new, unexpected and weird way, I don't mind the crashes, but I would like to learn why!!!!
Thank you very much in advance,
Adolfo.
