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

Summary: 7x5.5 Electric Prop

The Master Airscrew MA07550NE is supplied as an aftermarket replacement propeller for electric-powered model aircraft and comparable electric models. The following notes focus on correct use, straightforward safety checks for fitting, and how the prop interacts with typical performance adjustments without stating specific motor or hub compatibility.

Role and tuning: choosing a 7x5.5 provides a middle ground between thrust and efficiency for small electric models, favouring usable low-to-mid throttle responsiveness over raw top speed. In practice this size is useful when adjusting gearing or motor KV to refine the overall thrust curve.

Installation tips: examine the blade edges for damage before installation, make sure the mounting bore, spinner or prop nut is compatible with your shaft and hub, and confirm clearance from airframe parts. Perform a low-throttle static run after fitting, then balance the prop on an appropriate balancer to cut vibration that can affect bearings and on-board electronics.

Maintenance and safety: discard the prop if you detect cracks, chips, or delamination. Tighten fasteners to the recommended torque for your model, and do not use propellers that exceed the motor and ESC ratings.
