Hello,
I have a pixhawk driving my mini hex.
Today, as it was flying the motors just stopped and it fall from the sky (~2m).
There is no visual damages, however it can not take off anymore. Arms as usual, but upon giving some throttle the motors stop spinning and it disarms.
I tried motor test via mission planner and two of them, on a throttle >20% showing same behavior - start spinning and immediately stop, disarming (or maybe restarting the board).
I am not sure how to start troubleshooting - look in motors, ESC or in the borad.
Pleas help!
