For a second I thought about not posting my 4 gear results because I wanted to keep my advantage a secret. But then I came to my senses and wanted to spread the word, because this is something that will benefit racers soldiering on with their SC10 4x4's and what's good for one truck is good for the entire RC community. The SC10 4x4 has one big advantage the Tekno and Losi's can't match, which is it's light weight. Some say this is a disadvantage, and under certain conditions maybe so. But for me on a indoor track it is the perfect truck, and with the center diff and motor rotation issues fixed it is still very competitive.
