APC AP08038SFP PROPELLER 8x3.8SFP ELECTRIC SLOW FLYER REVERSE/PUSHER  [AP08038SFP]

Slow-flyer propeller overview

This APC AP08038SFP propeller is an RC-scale replacement part intended for electric slow-flyer aircraft configured as reverse (pusher) or standard rotation setups. The 8x3.8 designation identifies the diameter and pitch appropriate for low-RPM, low-thrust flight regimes commonly used in trainer and scale slow-flight models.

Fitment is straightforward on models that accept an 8-inch prop diameter and matching hub mounting; confirm shaft diameter and thread pattern before installing. Installation typically involves removing the spinner or nut, sliding the prop onto the shaft ensuring correct orientation for pusher or tractor use, and securing with the original washer and nut or prop adapter supplied by your airframe.

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