vtx failures and receiver failsafe
Two close calls and a crash.
Reception of the analog 5.8GHz FPV feed has been my main limitation. Vegetation and humidity seem to affect it greatly. I've tried to learn the areas where reception is good enough to fly and remain within those bounds but it's not always consistent and orientation of the drone plays a role as well. On two occasions this past month I lost reception completely.
In the first case I dived hoping that at a lower altitude reception would return. When a noisy image from the drone tumbling came back I switched to "angle" mode and recovered.
In the second the sun had yet to rise, the sky was clear and reception seemed excellent. I wandered a bit too far to a bad transmission area and lost the signal, dived and again switched to "angle" mode. I seemed to have recovered and thought I had put the drone back into "acro" but it was in "horizon" mode. I drifted to an area above trees and slightly behind myself again losing completely signal. I descended in "angle" mode and just as I was entering the trees I regained reception and pulled up. I was lucky to recover.
Unfortunately the last flight did not end that well. This time it was not the VTX reception. I was descending, no more than 40 feet up and maybe 40 feet almost directly infront of myself with virtually no obstructions when the 2.4GHz FrSky XM+ receiver on the drone lost reception and triggered an unexplainable "failsafe". Motors stopped and the drone dropped onto the asfalt infront of me. The camera lense popped off. There were multiple cracks in the frame and the LiPo was damaged. I was able to find and reattach the lense. The camera, VTX, receiver, flight controller and motors all seem to work. Parts to rebuild are on the way.
