Propeller Features and Use

The Master Airscrew MA07550NE propeller serves as an RC-scale replacement for electric model aircraft and other electric applications. The text below highlights practical fitting advice, safety reminders for installation, and the prop's role in general performance tuning without specifying motor or hub fitment.

Role and tuning: a 7x5.5 prop offers a compromise between thrust and efficiency on smaller electric models, tending to improve low-to-mid throttle response while limiting peak speed. Model builders often select this size when changing gearing or motor KV to refine acceleration and cruise characteristics.

Installation tips: check the prop for cracks or deformities before fitting, ensure the bore and spinner or prop nut match your shaft and hub, and confirm blade clearance around the airframe. Conduct a low-throttle static spin upon installation, then use a prop balancer or similar to reduce vibration that could impact bearings and electronics.

Maintenance and safety: replace the prop if you observe cracks, chips, or delamination. Fasten using the torque values recommended for your model, and avoid fitting propellers that push the motor or ESC beyond their safe operating limits.

Packing

  • Packaging varies by retailer; check the product listing for details on included items and accessories.

What difference does a 7x5.5 make to flying?

Switching to a 7x5.5 generally yields stronger midrange thrust and smoother throttle response, at the expense of absolute top speed. It is a common choice when pilots want more usable power for takeoff and manoeuvring.

Which balancing method is recommended?

Many builders use a simple static balancer first, trimming high spots or adding tiny weights as needed. After bench balancing, complete a low-throttle run on the model to confirm vibration levels in-situ.

When should I replace this propeller?

Replace the prop if you find visible cracks, chips, blade distortion, or any sign of delamination. Also change the prop after an impact that could have weakened the material, even if damage is not obvious.
