i am the perferct candidate to answer this question.. i own 2 revos and a hyper st. the Hyper is a TRUGGY so it only has one speed. It pulls like a raped ape out of the hole. If you arent going to race,just go head and get a REVO. my stock revo 3.3 just about loses to the hyper in a drag race. My hyper has the Sirio .23 and it flies. My other Revo with the sirio .27 takes it out only because it is a 2 speed. Make up your own mind if i had it my way i would own one of everytruck in production...
