How's the proportional break work? Doesn't allow the prop to free wheel and maintains a constant rpm I assume?

Aside of the geared/outrunner power, the problem I have with the outrunners is what do you do if you should have a problem. From what I can tell they're all sold through retailers that don't have the facilities to handle repair work. Not all problems have to do with the gear boxes.

Did you see any of the cyclons in France, observations?
