9x4 Reverse and Pusher Electric Propeller

This Master Airscrew MA0940NEP 9x4 prop is an aftermarket reverse/pusher item specified for electric RC airframes with rear-mounted motors. The model marking shows diameter and pitch and indicates its reverse rotation application versus a conventional tractor propeller.

Before fitting, check that the prop mounting method matches your motor shaft and spinner arrangement, confirm ESC and motor rotation settings, and check for sufficient clearance to fuselage and control linkages. Balance the prop to reduce vibration and protect flight performance and on-board electronics.

Operational notes: fitting a reverse/pusher prop can change airflow and thrust around the airframe; expect to retune control throws and throttle response following the conversion. Carry out progressive ground checks to validate motor and ESC performance and to confirm the aircraft reacts predictably.

What are the key compatibility checks for shafts and spinners?

Measure your motor shaft and verify the spinner or adapter will secure the prop correctly; ensure the chosen mounting method supports reverse orientation and does not contact the airframe when installed.

Any balancing and pre-flight checks you recommend?

Static-balance the prop, secure fastenings, confirm correct rotation at low throttle, and perform short ground runs to check vibration and clearance before flight.
