APC AP07038WSF Wide-Blade 7x3.8 Propeller for Electric Slow Flyers  [AP07038WSF]

Slow-Flyer Propeller Overview

This APC AP07038WSF propeller is an RC-scale replacement part built for electric slow-flyer aircraft. The designation shows a 7x3.8 diameter and pitch with a WSF wide-blade form intended to prioritise low-end thrust and stable slow-speed handling rather than fit a specific airframe or hub.

Installation follows the usual procedure for model aircraft props: remove the old prop or adapter, slide the APC prop onto the motor shaft or adapter, confirm the correct rotation direction, and secure with the original nut or retaining hardware. Check that the prop seats concentrically on the shaft and that there is adequate clearance with the spinner or cowling before the first power run.

On trimming and setup, a wide-blade slow-flyer prop will reduce top speed but boost static thrust and control at low RPMs, making it well suited for scale flying, training sorties, and smooth handling requirements. Verify static thrust, watch ESC and motor temperatures during initial flights, and balance the prop before use to minimise vibration and wear on bearings.

Maintenance recommendations: inspect blades after any hard landing for nicks or delamination, rebalance if you change the spinner or hub, and replace the prop if you detect structural damage. Always perform a mounting hardware safety check prior to every flight.
