Electric Series 7x5.5 Replacement Propeller Master Airscrew MA07550NE  [MA07550NE]

Electric Propeller: 7x5.5 Details

The Master Airscrew MA07550NE is offered as a replacement propeller for electric model aircraft and other similarly powered RC models. The notes below concentrate on safe installation practices, routine maintenance, and how the prop influences basic performance tuning without asserting specific motor or hub compatibility.

Role and tuning: a 7x5.5 blade profile aims to deliver a practical mix of thrust and efficiency for smaller electric models, improving low-to-mid throttle response while limiting maximum speed. Model tuners commonly use this size when altering gearing or motor KV to refine the thrust curve to their preference.

Installation tips: inspect blades and the centre bore for damage before fitting, confirm the spinner or prop nut and bore fit the shaft and hub, and ensure adequate clearance to the airframe. After fitting perform a low-throttle static spin, then balance the prop using a balancer or equivalent method to minimise vibration that can affect bearings and electronics.

Maintenance and safety: discard the prop where you detect cracks, chips, or delamination. Follow manufacturer torque guidance for fastening, and do not operate the prop if it pushes the motor or ESC beyond their rated capability.
