Hi there I have this truck but I cant coment on the differences as Ive never had a revo but the truck is excellent its really powerful.Ive looked through my instructions and cant find a two speed trani in them under the optional parts listing. The truck is easy to maintain and clean.One word of warning! make sure your LHS has a good supply of parts or has good ordering from hotbodies as Ive had trubble getting parts.I live in the U.K so parts might be easier to get if you are in the USA. Hope this helps in your decision.
