8x3.8 APC AP08038SFP Electric Slow-Flyer Prop - Reverse and Pusher Use  [AP08038SFP]

Overview for low-speed propellers

The APC AP08038SFP propeller serves as an RC-scale replacement for electric slow-flyer models and can be mounted for reverse (pusher) or conventional rotation. Its 8x3.8 size denotes a diameter and pitch combination tailored to low-RPM, low-thrust flight envelopes typical of trainer and scale slow-flight craft.

Installing this prop is simple on models that accept an 8-inch diameter and compatible hub; check shaft diameter and thread type before proceeding. Installation generally requires removing the spinner or nut, placing the prop onto the shaft in the correct orientation for pusher or tractor use, and fastening with the original washer and nut or an appropriate prop adapter.

Handling and trim notes: in slow-flyer setups the propeller influences climb behaviour, throttle feel and stall onset more than top speed. If you swap between standard and pusher layouts confirm motor cooling clearance and balance the propeller to keep vibration low and protect servos and structure.
