Hey guys,
So, I had a crash a couple of months ago and broke one of my arms. Now, I've waited for two months to finally get the replacement arm and fixed it. But now, when I tried to test fly it, the quad keeps falling out of the sky for no reason. The distance is always different, sometimes 100 m and sometimes very close (in the video its about 5 m). I didn't change any settings in Betaflight, and this quad was flying fine for two years with my settings. The motors don't get hot, and I don't see any physical damage to the drone. Nothing is touching the props. I have the blackbox file attached with my latest test flight dvr video.
Just after the quad disarms, you can see that rxSignalReceived and rxFlightChannelsValid are still 1 and that failsafePhase is still 0. So, the flight controller itself isn't seeing a failsafe condition. It looks like it just disarms for some reason.
Does anyone know what could cause this? Thanks!
