I already have the 2.5/1515 (1700kv) on 4s its a bit slow (20/51, maxx/gorilla tranny w/1/8 buggy diffs) I know mike makes a 22 and 24 pinions, on 5s its awsome with the same gearing. I like the 2200kv motor for 4s racing, My track runs RC Pro rules and that will allow me to run my electrics in nitro. Whoever said that speeds to match Nitro's is correct, my 5s powered revo is just too much for the track, it accelerates faster than my V-spec 8T, which is very impressive for a .21 truggy
