ok, I picked up an RC10 the other day used, that's all I know.. it came with an AE .15 with a pullstart on it. I immediately bought an OS .12 cv to put in it, I've finally got the clutch assembled and bolted it to the chassis, but it don't look to me like my bump start box is going to fit in the little slot, what did I miss on my pullstart/nonpullstart conversion?
