Please help finding the issue. Some more informations:
Tarot X6 airframe
Tarot 5008 motors
T-Motor S45A ESCs
Pixhawk 2.1 with PX4 flight stack
Take off in Position control mode. I was hovering a few meters above the ground, testing pitch and roll reactions to tune the PIDs.
The ESC got in fire while flying, the prop slowed down and the copter started to lose altitude while yawing. I had to find a good place to land as soft as possible, fortunately it seems I had just the ESC burned and its motor is a bit harder to turn.
