Master Airscrew MA1160NEP 11x6 Reverse/Pusher Propeller  [MA1160NEP]

Aft-Facing Electric Propeller Guide

This 11x6 reverse/pusher propeller is intended as an RC-scale replacement for electric model aircraft that use pusher or aft-facing prop configurations. The construction and blade form are targeted at common electric model layouts where rear-facing mounting is required by the airframe.

Installation notes: confirm hub fit on your motor shaft and install the correct mounting hardware, check rotation direction and blade orientation for reverse or pusher installations, and ensure adequate clearance to the fuselage and tail before the first flight. Use thread-lock on metal fixings if vibration warrants, and carry out standard safety checks for prop mounting and pilot separation distances.

Tuning role: this propeller affects thrust, motor rpm load, and airflow over tail surfaces in pusher arrangements. When selecting motor KV and pairing an ESC, factor in how an 11x6 pitch will influence target rpm and battery current. Balance the propeller before use to reduce vibration, and perform measured throttle checks to verify motor and ESC temperatures remain within acceptable ranges.

Practical advice: if a spinner or shroud is fitted, make sure prop clearance is adequate and trim spinner bores precisely. In pusher installations observe efflux interactions with control surfaces and the cooling airflow to motor and ESC; adjust mounting or add deflectors if required to maintain effective cooling and predictable control response.
