What was your motor temp when you tried A123 + 7.5R @ 32mm rollout?
If it is already hot, then you should re-gear for sure.
I would suggest to aim at about 28mm rollout to start. (so use 19 pinion)作者: tekin 時間: 2010-8-20 20:50
i use 94/20, but i don't know that is ok or not???
c-hing, what's gear ratio do you suggest??

this means for 1 motor revolution, your car will travel 30.7mm
note:
when you use foam tire, usually refer to rollout
when you use rubber tire, usually refer to FDR作者: tekin 時間: 2010-8-20 22:55
