Yesterday I launched my drone as usual, aiming to fly around and get some nice footage. Prior to flying away I did all checks - it was holding position, and also it was showed correctly on the map via telemetry.
However, suddenly telemetry reported lost gps lock. So I switched into stabilise mode and tried to land the drone. It was rather hard, due to the lay of ground. So when telemetry reported that gps lock was recovered, I switched consequently into PosHold (didn't actually hold position despite HDOP 0.8) and then RTL. When it got to RTL, the drone just started to fly straight away. The last command it DID get was LAND (confirmed by telemetry). But it continued flying away straight into the sky.
The last reported position was waaaay away from me and absolutely not in the direction it was flying to.
Search failed, so as a result I lost it together with my camera and gimbal. Apart from being somewhat very sad I'm puzzled: how come it happened?
It was using tested settings on Copter 3.3.3, I had the system (and GPS) working flawlessly for half a year (checking telemetry after each flight). None of failsafe triggers worked (I had fence, radio and battery enabled and working before). Now what I guess here is that it all might have failed cause it was set to RTL - and the drone might somehow got my home position jinxed. However, it doesn't explain why it didn't LAND when receiving such command.
Also, telemetry link died at the same time with radio link, which is very strange, cause radio has a way better range
Does it mean that pixhawk is no better then the old DJI NAZA? I've been a fan of 3DR for almost three years, but this flyaway saddens me greatly. Also, that's lost money.
