APC AP08038SFP 8x3.8 Slow-Flyer Propeller (Reverse/Pusher Compatible)  [AP08038SFP]

Slow-flyer propeller summary

This APC AP08038SFP propeller is a replacement part for electric slow-flyer RC aircraft and supports reverse (pusher) or normal rotation installations. The 8x3.8 marking specifies diameter and pitch suited to low-RPM, low-thrust flight commonly found on trainers and scale slow-flight models.

Fitment is straightforward on airframes that accept an 8-inch prop and matching hub; always confirm shaft diameter and thread pattern before fitting. Typical installation involves removing the spinner or nut, sliding the prop onto the shaft in the correct orientation for pusher or tractor use, then securing with the original washer and nut or a suitable prop adapter supplied by your model.

Tuning and handling notes: on slow-flyer rigs the propeller strongly affects climb rate, throttle response and stall characteristics rather than top speed. When changing between standard and pusher configurations check motor cooling clearance and balance the propeller before flight to minimise vibration that can impact servos and airframe components.
