would be cool, but most people dont realize that a 2 speed on a nitro is for accelleration, I found this out when everyone was hooplaing about that one time, I have a 2 speed truck and couple 1 speed trucks, the 2 speed truck out accellerates my 1 speed trucks big time, if i were to put a better motor in it it would probably also beat them out on the top end too. Although You could gear up your truck to have a large second speed gear and make it top out. or you could get a shumacher menace which has 3 speeds, and I am assumming that it takes a long strip to get to use the 3rd gear.
