the track is 95x38. i will be running a kc 19turn motor with a darkside slider car. just looking for a great ballpark guess on the spur and pinion for this set-up.

thanks

ok ok i should know

ok i know i should know this but i have never heard of roll-out. we just always used ratio's, when getting a gear set-up. can someone get me the spur and pinion teeth number so i can get close. the motor is a kc 19 turn.

thanks

Gearing depends on tire size when it comes to foam tire racing.

roll-out

ok... how do you figure roll-out? but most of my tires are around 2.15 diameter.

 

[Mr.Wolfman]

Roll out is how far the car will travel with one revolution of the motor. This takes into effect your tire size and gear ratio

diameter of tire x pi (3.141) divided by gear ratio= roll out.

having two axles with a 2 tooth difference (say 118 and a 120) will let you dial in when your tires wear down.
