rooster crawler combo

[jer0219]

Picked up a rooster crawler combo with the 55t motor. I would like more wheel speed, any recommendations? What would be the largest pinion that would fit with the stock spur on my scx 10.

I run a 20T on my 55 Turn, It has enough wheel speed and is still crawlable.

shulda got the new novak 45t insted unless you already had it but try a smaller spur gear like 76t and 23t pinion
