Electronic Speed Controllers Burned Up

[Chris Thomas]

Per my post below my drone was upside on the ground and running. I could not get it to turn off for about 45 seconds. During this time two blades were broken and one Electronic Speed Controller began smoking. When I took the drone apart there was a wire off of the ESC which was smoking and I soldered it back on. When I powered up the drone the ESC I soldered and another one burned up.

I have ordered two new ESC's but now I am wondering if the two brushless motors were damaged when they were on the ground and the damaged motors caused the ESC's to burn up? My thought is that the ESC cooked because the motors where not spinning but that the motors may be okay. Any guidance on this would be appreciated. Thanks.

Hi yes normally the motors are ok the ESC will go over its amps if a motor is jammed , they do make ESCs that have a jammed motor cut out
