Hi there,
Just picked up the SP Short course master and plugged it into my Losi XXX SCT. I have a Tekin Redline 17.5 motor in there and after getting everything all soldered up and running it, it just seems very slow. It might be gearing (23/88) but it just sounds like the motor isn't spinning up to it's highest RPMs. Seems like it was faster with the RTR combo that had the same spur but a lower pinion. Is there some setup issue that I'm missing?

Thanks.
