I am noticing that the majority of the latest E-machines are designed around inrunners and having run both as well as maintained both (I mean removed and greased an inrunner) I can not comprehend why anyone even considers an inrunner. The savings in efficiency are so trivial as to be meaningless to the average RC pilot. So let the "flaming" begin:
Why do you use an inrunner?
Outrunners are better, no?!?
Keep it nice and remember its only a hobby
