You can turn your prop 1/2 revolution before it catches?

It shouldn't do that.

prop or internal?

Hard to say without seeing it.

I wouldn't discount the spun hub. There is a lot more force being applied to that area at WOT than what you are putting on it by hand. I have one with a spun hub that I really have to pry down on by hand to make it slip but you can't run it on the motor above 1/4 throttle before it slips.
