Small's not a problem. You extend it and give it wider arms. The RC10T was originally a buggy too, remember? So has every truck in the RC10 series, including the SC10. What'd they do? Made it longer and gave it longer arms. Insta-truck.
It would be kind of nice to see the whole 2wd ST series go CORR-style, but that would mean that a lot more companies have to hop on to get it done. Losi would have to put down a serious offering, as would Kyosho, and the other large names in the 1/10th 2wd ST class.
It would be cool, but I really don't see it happening any time soon. I'm seeing the SC10 more as a cash cow.
