Just picked up this truck in a trade and need some advice.He says all it needs is a connecting rod but i think it needs a piston too and i found this other part that is broke also.This is my first nitro truck and i know very little.Is it worth trying to fix the current motor or should i try to find another.And what else can i put in for a motor.How good is this vehical compared to others out.Hear are some pics.
