I agree with you misshydro ,but sense I am racing for the first time and this RTR class is brand new and they still have a lot of bugs to work out I,m willing to run the Elam stock for now. I bet they would still let me run if I put a .18 in it ,but I just paid 300+ dollars for this boat so I want to get my moneys worth out of this engine be for I go and spend money just to keep up with the other guy.
