Uni-UAV ~ Power Train - Overrunning Clutch

Notes:

Overrunning clutch for Rotors will be required. The requirements for it are the motor seizing, or speed controller locking up or free-wheeling.It looks like placing an overrunning clutch in the driven gear of the Intermediate Reduction (on x-shaft between final reducers) should satisfy all.

Overrunning clutch for Propeller may also be required between the Speed Controller and the Propeller; to be available during speed controller lockup high-speed flight. However, being a UAV this may not be required; or, by being available it will allow the craft to safely return by rotors alone.
