[brian s]

need to know what gearing to use on a mad rat running a 13.5 novak brushless

31 or 32 I run a 10.5 on a 28

On th e mad rat you will have a 86 spur try to take the 80 of the x pro

[brian s]

spur is an 80t, will try a 30 and see what it`s like. thanks for the info.

Im using 78/27 with success on a medium indoor track. So the 27 or 28 would be good for the 80T

Where did you find the 78?
Did you use an AE or kyosho?
