I really need some help on gearing my touring car right. My car is Yokomo MR4TC SP (internal ratio is 2.2)
All my pinion and spur are 64dp
I have set my car to 25t x 108t (spur) , i found there is no top end speed at all.... I tried 27t,19t,15,12t motors
then I tried 33t x 108t, I feel the acceleration is great, but the top end is still lacking.... my friend's 27t motor set-up can beat me on straight ;(
Ok, I bought new set of pinion from HPI 40T(pinion) 90T(spur), going to fit it on my 12x1T reedy ti motor.
I can feel it's gonna be faster , but then I read from web forum... wrong gear may damage motor because Overheated.
Can any expert tell me how to gear a car to go fast without damaging my motor,etc?
Please please help !作者: oej 時間: 2008-8-14 19:00
