So I have a f450 Naza with the DJI 2212 motors with 3 lighting hobby 30a esc and 1 Quadkopters 30a esc.
Since few days I'm noticing that during arming the motors, the one connected to the QK esc sputters at startup and has a few seconds delay before spinning.
Today after 4-5 flights when I powered up the Quad and did the arming process sparks were seen from the motor and also smoke from it. I turned it off and inspected it, the motor was very hot and the esc was warmer as compared to the others. The motor wouldn't spin freely as others, it appeared jammed.
It seems that the motor has burnt off? Also has the esc been damaged as well since it was warmer than the others. I have a 600mw vtx power input from the same esc points if that's relevant.
Help will be appreciated. Thanx
