I was testing out my quad on my 3rd actual flight and had a ‘fly away’ type situation that I think was caused by a combination of GPS glitching and a geofence RTL setting. While flying very close LOS, I had GPS failsafe disabled and geofence settings enabled. The wiki states that in that situation a loss of GPS lock will disable the fence settings. Before the flyaway I noticed GPS lock dropping in and out with no affect. According to the logs, I had multiple GPS glitches and then a geofence initiated RTL. Surprisingly, the quad sped off away from home at an altitude less than the fence setting. As it almost hit a nearby tree line, I quickly switched modes back to stabilize and immediately throttle dropped the quad the 15-20 ft.
Is my understanding correct? Is the response from the quad as expected? Thanks for the help.
