thats the thing with the dynamite .12SPD compared to the O.S. .12 Cv-R. So close in power it was really available traction. Any stadium truck cant really use more than 1hp. It may with some heavy front ballast and battery pack upfront and some very large monster truck tires (like masher 2K's) and very tall gearing. Even then its almost too much power for a ST.[&:]
