Hoping to get some expertise on deciphering my logfile after a crash of my trust 3DR Y6 on flight #106. I interpret a radio signal loss failsafe causing a near inversion of the craft near the ground and a correction to upright attitude before impact but still enough vertical speed to cause damage. I’ve had plenty of failsafes usually causing the desired RTL behavior, which I often interrupt with a loiter command and then resume flying.
The logfile shows a very aggressive roll upon failsafe RTL, causing the momentary inversion near the ground. I can’t quite explain it.
This is a RTF 3DR Y6 using DragonLink UHF contro, with gimbal, GoPro, minimOSD. Using APM Copter 3.0.1. It is my usual flying field at about 1400’ elevation. Range was about 500’. Altitude 10’ AGL. Flight was a mix of loiter and altitude hold, with the failsafe RTL intervening. Battery life was 6 minutes into a 10 minute proven flight duration.
Log attached. Any help is greatly appreciated!
