Outrunners supported/held by the shaft?

[zeropointbug]

I think I might have to just spill the beans, because I am still trying to work out a few design issues in my head before I can even CAD it. The issues are mainly due to not knowing exactly how the outrunner in question is put together and a couple of 'assembly' unknowns.

I'll be on later to post a a simple drawing of it, and explain how it work... we may as well do this together!
