im trying to put a dtx .18 on a friends rustler. his traxxas 2.5 engine died and im trying to put my evaders dtx .18 on it but the flywheel is too big. i tried to look at the manual to see how to remove flywheels but they dont say. im going to trade flywheels on the two and im wondering how to take flywheels out.

thanks.
