Mike, Get With Kris Flynn. I think he's selling a nice kit to put a motor on an OS lower. I have a UL-1 motor on mine with an adapter my neighbor made for me. If you don't buy his kit, at least buy his collett. I'm also running the UL-1 ESC.I wanna build a FE VS-1 what parts do I need to put a motor on it?
