APC AP0938SF PROPELLER 9x3.8SF Electric Slow Flyer Propeller  [AP0938SF]

Slow-flyer propeller for electric models

This APC AP0938SF propeller is an RC-scale spare designed for electric slow-flyer models where low-speed thrust and smooth response matter. The 9x3.8 designation identifies the diameter and pitch that influence thrust and motor loading, making it suitable for gentle cruising and basic training flights.

Fitment and orientation are straightforward: mount the propeller on the motor shaft following the rotation arrow, confirm the prop seats flush against the hub or spinner, and secure it with the model’s existing fastening hardware. Always check for adequate clearance from the airframe and control surfaces before powering up.

In tuning terms, the 9x3.8 size trades a bit of top-end speed for improved low-RPM thrust and propeller efficiency on slow-flying setups. If you adjust prop size or pitch, reassess motor load and ESC settings to keep temperatures and current draw within safe ranges for your electric system.
