7x5.5 Electric Propeller for Electric RC Models Master Airscrew MA07550NE  [MA07550NE]

7x5.5 Electric Propeller Overview

The Master Airscrew MA07550NE propeller is a replacement RC part intended for small electric model aircraft and other electric-powered models. This section covers practical use, basic installation safety checks, and how the prop fits into general performance tuning without claiming specific motor or hub compatibility.

Role and tuning: a 7x5.5 propeller is chosen to balance thrust and efficiency on small electric models, trading peak speed for stronger low-to-mid throttle response. In real setups this size helps match motor and ESC selections to desired flight behaviour and is commonly used when changing gearing or motor KV to achieve a preferred thrust profile.

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

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