On the car engines Davis deserves a lot of credit he now has a high strenght rod I believe for Traxxax bushed both ends oil holes a call or e mail to him will confirm the exact engines
even if you never convert the engine to diesel this is a great upgrade. Its really nice when a needed product is developed to solve a problem

This is not the first time he has done this he has had a high strength HD crank for years to solve the snapped cranks in the cox which saw lot of use in mouse racing
and a new one in in RanD for the cox also martin
