Since I started upgrading my electric ships to brushless power, I've bought nothing but outrunners. I have two AXIs and one PJS. So, that should tell you that at the very least, I think they're good. There may not be much talk about outrunners here, but there's plenty in the 'electric motors, gear drives, and props forum', and there's even more in the power systems forum on rcgroups.com. Look around; you'll find plenty of info, you just have to dig.
