A question was asked on another forum, as to wether or not anyone makes a single speed conversion for the Revo. This sparked my interest, so I figured out the gear ratio's that would get me closest to a truggy's final drive ratio.

I did some reverse engineering, and machined a part that replaces the 2nd gear primary clutch. It is a direct drop in, no mods required, and we lose some weight. First gear is removed completely.

I actually machined a whole bunch of them after doing some R&D. PM me if you are interested.
