Master Airscrew MA0635 GF Series 6x3.5 Fixed-Pitch Propeller  [MA0635]

GF Series 6x3.5 Prop Overview

This Master Airscrew MA0635 GF Series 6x3.5 propeller is a fixed-pitch RC prop built for small electric park flyers and foam models where a practical balance of thrust and efficiency is wanted. The 6x3.5 designation is a nominal diameter and pitch reference for matching motors and airframes rather than a promise of specific performance on any single model.

Fitting is straightforward on compatible prop hubs and adapters: make sure the prop sits centrally, secure it with the correct nut or adapter, and follow the motor manufacturer's recommended torque for the spinner or prop nut. Verify rotation direction and spinner clearance before the first run.

From a tuning standpoint, the 6x3.5 tends to trade maximum speed for steadier low-to-mid throttle thrust and smoother response when compared with higher-pitch props. Use it during a prop sweep: change pitch or diameter in small steps while recording motor RPM, ESC temperature, and flight feel to identify the best compromise for your setup.

Pre-flight checks should include a static balance check, a visual inspection of the hub for cracks, and confirmation there is no warping from impacts. Replace the prop immediately if any damage is found to avoid unpredictable handling or excess load on the motor and ESC.
