yeah, i know what you mean... himoto was in a rc site last year and they said these speeds were "tested"... so who knows...?? USING 100 FEET MARKS AND A STOP WATCH MINE DID CLOCK IN AT APROX. 60 - 65 MPH (thats with 30% nitro, high performance air filter, no body, and warmed up.) i dont think anyone not even redcat knows exactly but i just gave the speeds himoto gives and they sound pretty reasonable....
