Master Airscrew MA07550NE Electric Series 7x5.5 Propeller for electric RC models  [MA07550NE]

Electric 7x5.5 propeller overview

This Master Airscrew MA07550NE propeller is an RC-scale replacement part aimed at electric model aircraft and similar electric-powered models. The writeup focuses on practical use, safe installation checks, and how the prop fits into basic performance tuning without claiming specific motor or hub fits.

Role and tuning: a 7x5.5 propeller is used to balance thrust and efficiency for small electric models, trading top speed for usable low‑to‑mid throttle response. In practice this prop helps you match motor and ESC choices to flight behaviour, and is commonly used when adjusting gearing or motor KV for a desired thrust profile.

Installation tips: inspect the prop for damage before fitting, ensure the mounting hole and spinner or prop nut match your shaft and hub, and check blade clearance from airframe surfaces. Before first flight perform static spin checks at low throttle, then balance the prop on a prop balancer or equivalent method to reduce vibration that can affect bearings and electronics.

Maintenance and safety: replace the prop if you find cracks, chips, or delamination. Secure fasteners to manufacturer torque recommendations for your model, and avoid overloading the motor by using props outside the motor and ESC capability.
