Just wonder if have a problem with nose diving off jumps? I have an LX1 also with ezrun150 and workig on a new motor since the last one the motor screws stripped. I am also running the nylon spur which is a 51 tooth and 13t pinion. Also, i fear my motor mount is bent forward after a hard crash that stripped the screws.
Did you need to space the motor mount up for the spur you run?
