Rustler vs. Rustler

I was running 19/56 before and at times my motor was getting on the hot side but ESC and Pack was nice and cool. I was going to run the 21t I got with teh 56t spur but it would not mesh properly, too tight. Maybe I will get a smaller spur and try it with the 19t and 21t and see what it does as far as temps and stuff. I would just think if I was undergeared it would be really torquey down low or am I wrong?

Def undergeared then. Gear up. It sounds counterintuitive, but it will work. My medusa was undergeared at first, was slow and wouldn't wheelie. Geared up a few teeth, then it was a whole 'nother motor. Fast, mega-wheelies, very impressive. The motor needs a certain amt of load before it will make alot of power. Shouldn't really get warm either.

Thanks bud glad to hear that! For example today, I ran a whole 2s pack through. Temps were: ESC: 78, lipo: 108, motor: 138. Then I ran my 3s pack and temps were: ESC: 85, lipo: 98, Motor: 168.

I was keeping an eye on my temps the whole time. Disabling the punch did help some it seemed. I will now gear up to 19/56 and see. Once I get my 54t I will try that with the 19 and 21t pinion.

Thank you all for the advice. Have a nice weekend!
