APC AP11038SFP propeller 11x3.8SFP electric slow flyer reverse/pusher  [AP11038SFP]

APC 11x3.8SFP propeller overview

This APC AP11038SFP propeller is an RC-scale accessory designed for electric slow-flyer model aircraft configured in reverse or pusher orientations. It is intended to help pilots tune thrust direction and balance for low-speed flight regimes common to trainers, sport models, and scale slow-flyers.

Use this propeller only on model aircraft with compatible motor shafts and prop adapters. Before flight, mount the propeller securely, ensure correct thread direction for pusher or tractor mounting, and balance the blade assembly to reduce vibration. Check clearance to airframe and control surfaces when installed in rear-mounted pusher positions.

In tuning, this prop contributes to thrust distribution and pitch response; small changes in prop selection or mounting position can affect trim and elevator authority at slow speeds. Perform incremental tests and use proper safety procedures during ground runs.
