Like he said though with the ek4 roll over, if u want punch for the same price, get the .18 sirio motor for the tmaxx, itll be much faster and torqier.
CaseyDDR,
Will the 18 sirio work with the original EZ start on the T-Maxx or is it a PS engine? Does not really matter to me but one of the big selling points for me was the electric start on the T-Maxx, would be cool to keep it if I change motors.
