I did some checking on the AE forums and the general idea is that the drivetrain is to tight from the factory. So,I did a small mod with a dremel to remove the front belt tensioner and it rolls MUCH easier now and I relubed the drivetrain. And then I installed a custom aluminum heatsink so hopefully this will do it.

@bondonutz--I'd honestly hold off on the purchase until AE fixes the drivetrain issue,there's no way in he'll it was supposed to be that tight.some people are converting the more efficent RC18B series into an SC,maybe there is a possibilty? But if your ok with fiddling with it to cool it down and a motor change,I'd say go with it (for some reason BL SC18 don't heat up?) but other than that I've beat the ever loving piss outta mine and it takes it like a champ!--Josh
