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

Designed for Low-RPM Stability

The APC AP07038WSF propeller serves as a replacement component for electric slow-flying RC aircraft. Its 7x3.8 size combined with the WSF wide-blade profile focuses on delivering strong low-speed thrust and predictable handling rather than matching a single aircraft type.

To fit the prop, remove the existing prop or adapter, place the APC prop onto your motor shaft or prop adapter, confirm the rotation orientation, and secure with the factory nut or retaining device. Make sure the prop sits concentric to the shaft and that the spinner or cowling does not contact the blades before the first run.

In flight tuning, expect more low-end thrust at the expense of top speed; this makes the APC AP07038WSF well suited for relaxed scale flights, basic training, and operations that require steady low-speed control. Measure static thrust during initial setup, keep an eye on ESC and motor temperatures, and balance the prop before installing to reduce vibration.

Care and maintenance: check blades for chips or delamination after impacts, rebalance if you alter the spinner or hub, and replace the prop if structural faults appear. Regularly inspect mounting hardware as part of your pre-flight routine.
