I just bought a used Novak C2, and it has started making a strange popping noise. Under full throttle (which actually feels like about half throttle) the popping happens about every 5 seconds. The closest thing I can compare it to is a backfire
. This is the first ESC that I've owned with a power capacitor. Maybe this is a sign that it's fried? Any other ideas? I'm using a stock motor.
(Sorry if this is a stupid noob question; searching for C2 doesn't work.)
