hello all,
I have a Castle sidewinder esc with 4600kv motor that has just gone on the fritz. My problem is when I put the car in reverse, the car does not move. Forward works as does the brake. I have noticed that the esc flashes RED rapidly, when full reverse is applied. I have tried calibrating it a couple of times but it still has the same problem.

Any ideas on how to fix my problem?
thanks
