I think it is designed around the *junk imo* inrunner/gearbox setup, but you can put an outrunner on the stick with a special mount... Personally I would wait on the edge and watch some videos, listen to what people think about it, because as advertised, it will have a higher wing loading than the mini funtana, which imo, is a fat pig... however, the video of the mini edge looked alot better 3d'ing than the mini pigtana...
