I think I got my motor shutting down problem solved in my Copperhead R/5150. The EPA on my steering servo was way off. I adjusted it and put a 12T pinion on it. Yesterday I ran four packs and had no issues. This was with my SCTE converted to an e-buggy. So far temps have been good. If the temps start to get too high what should I adjust? Also if the esc gets too hot will it shut down before it frys?
