I'm having the same problem. I went to the track today for a practise and managed to short circuit the wiring for about a second. Never done that before, and certainly won't do it again.

So I corrected the battery connector and plugged in and switched on. As soon as I switched the switch, smoke started appearing from around the esc area. I decided to come home to sort it out.

After testing it home, it appears to have developed a severe case of cogging. I haven't run this set up before, so not sure if my wiring blunder has anything to do with it or not... At first it was just a bit rough - it would appear to take about half a second to decide which way to spin the motor. I've read lowering the gearing helps, but it won't turn without a pinion!

I have a sphere tc esc and nosram storm evolution 10.5 motor and also get the red and orange lights if a hold full throttle for a few seconds.

Any help gratefully received. I don't know whether it's the motor or esc.

Cheers,
Barry
