This is the engine I won the O’Donnell Off-road Championship with. What is interesting is that through a broken diff that was binding the drive train at a big race, I had what seemed like no power, so I kept telling my pit man to lean it out ( main event ) and he did so… until it got very hot indeed. It got up to over 400 degrees and was still running well. We thought it would have trashed the engine but we were wrong. With NO rebuild at all, that is the very same motor that won the O’Donnell. Now that same motor has won AGAIN, the RD Logics Off-road Championships in the Expert Truggy Class. These motors are so well made and such quality it is just amazing.
