Direct Drive to Diff E Revo Build

[Matthew_Armeni]

Maybe I'm wrong, but doesn't a Centax clutch work like that? Or is it the balls themselves that apply the direct force on the clutch? I know that it uses balls set in a concave hole so when the flywheel spins the balls are forced outward but the shape of the hole they sit in forces them forward as well. What I don't know is if they touch the bell or touch something else that in turn touches the bell. Any thoughts?
