Reverse-Orientation 9x4 Pusher Prop for Electric Models

The Master Airscrew MA0940NEP 9x4 propeller is designed as a reverse/pusher accessory for RC electric setups. The designation communicates size and the reverse mounting orientation suitable for rear-mounted motors rather than standard tractor installations.

Fitment checklist: ensure the spinner or adapter fits your motor shaft, confirm ESC-controlled rotation is correct for reverse operation, and verify there is clearance to the airframe and moving linkages. Perform static balancing to cut down on vibration that can affect handling and electronics.

Tuning advice: switching to a pusher configuration alters thrust distribution and the airflow over tail surfaces; plan for iterative throttle and trim tuning after installation. Conduct incremental power runs on the ground to check motor temps, ESC response, and overall handling before extended flights.
