T-maxx Custom Truggy Chassis

[suicideneil]

Given the lack of additional gear reduction from a tranny, you will need a fairly large spur and small pinion (any 6 spider center diff will be great).

Based on some rough mathes, a normal emaxx geared for 40mph uses 62/24 + the tranny; with just a center diff and the motor pinion, 52/12 gives about the same result. I would suggest using the calcultor to play aropund with your gearing options based on what a normal t-maxx would need to be geared at to achieve a certain speed....
