So I have seen some shooters from overdrive that work by winding a cord around an axle to draw back a spring or tubing. Then they lock in place via many different methods (locking pin, winch, ect.)
My question comes about the release. When you release the mecanism, does it unwind the motor? Or, is there some sort of clutch mechanism that lets it slip so that you don't lose force from winding the motor? If so, what is it?

Thanks in advance.
