Hello, I have the castle creations sidewinder sct combo in my hpi blitz. I loved it at first, but realized that compared to most other people running this motor (dont care much about esc) I am getting very low performance. Yes I have checked on gearing, settings, and of course the voltage. (most were running 2s lipo). When I am at the local indoor offroad track, I cant even clear the triple at the end that even brushed slashes are clearing. I have never over heated the motor and the esc has never actually gone into thermal shutdown to my knowledge but I have had nothing but problems from this esc. It randomly shuts down and turns back on, it stopped making the noises at the beginning (when you turn it on and stuff). And so on. I did manage to kill the origional motor that came with the set. I sent it in to castle and they said that it would cost more for them to repair it than it would to just send me a factory refurbished one. So that is exactly what they did. A few days later I got it in the mail in a retail box. Plugged in fine but didnt make the noises. I know that it is possible for a bad esc to kill a good motor. Should I just send in the esc and motor?

I run on 2s lipo and 7 cell nimh. gearing for the track is 19/88 I think. I may sound stupid and my spur is just big. Should I change my spur before sending it in? I would guestimate the speed with that gearing to be about 20-25mph if that. I have seen this combo do wheelies with this truck out in the street when I first got it. Now, it just kind of stutters a bit then kind of ramps up to speed. It doesnt have that low end torque that I was hoping for and have seen when I first got the combo. But I think I had an 83 spur when I first got it. So maybe that is my problem.

Any suggestions?
