Hey I’ve got some logs from yesterday of a pretty nasty crash that we saw with our Foxtech GAIA 160S hexacopter. We have it equipped with a Pixhawk 2.1, HERE 2 Gps, etc.
The drone was experiencing some high-ish winds (gusting to maybe 15mph at most) while we were flying it. It made the drone fly turbulently enough to cause us to bring it back down below the tree line where the winds were lower. We then flew it out from us maybe 350 feet. At this point we saw what appeared to be a motor failure and a copter trying its hardest to stay in the air. It was yawing wildly and I saw no hope of getting it back in Loiter mode so I switched to RTL at which pointed it fell out of the sky.
We were able to recover the drone but surely suffered close to $10K in damages. Looking at the logs I see RCOUT C7 peak and C8 drop to the bottom. In my mind this would indicate that C7 died but pixhawk was begging it to keep spinning and C8 shut off in response. C8 is motor 2 which should be a the 9o’clock position on the drone and C7 is the motor at the 3o’clock position on the drone. (I would need correction here if I am wrong about that).
I would just like a second look at the logs for someone to confirm that is indeed the case and would also welcome any speculation as to why this happened. Of course we want to repair this drone and keep flying but would like some assurance we are stopping it from happening again.
