APC AP11038SFP 11x3.8SFP Propeller for Electric Slow-Flyer Reverse/Pusher  [AP11038SFP]

Mounting and fit notes for APC 11x3.8SFP

This APC AP11038SFP propeller is an RC-scale accessory intended for electric slow-flyer model aircraft arranged in reverse or pusher layouts. It helps adjust thrust vector and balance for the low-speed flight regimes typical of trainers, sport models, and scale slow-flyers.

Fit this propeller only to motors and hubs that match the prop adapter and shaft specifications. When installing, confirm the correct thread orientation for pusher or tractor mounting, tighten securely, and balance the assembly to reduce vibration. Verify clearance from the airframe and control surfaces when used in rear-mounted locations.

In practice, this blade affects thrust distribution and pitch response; modest changes in prop choice or mounting position can alter trim and elevator feel at slow speeds. Carry out stepwise checks on the ground and follow accepted safety procedures during initial runs.
