APC AP1103 Propeller 11x3 RC Aircraft Propeller  [AP1103]

11x3 RC Propeller Overview

This APC AP1103 11x3 propeller is an RC-scale replacement part intended for electric fixed‑wing models that accept an 11x3 sized prop. Its role is straightforward: provide the correct diameter and pitch to match motor and airframe setups where an 11x3 prop is specified.

Compatibility depends on the model's accepted prop diameter and hub fitting rather than brand names, so verify your motor shaft, prop adapter and retaining hardware before installation. The prop should be mounted on a matching adapter or hub and secured with the appropriate nut or collet used on your motor.

For setup and tuning, use the 11x3 designation as a reference for expected thrust and top speed tradeoffs, then confirm motor and ESC temperatures under load and balance the prop before flight to reduce vibration and wear on bearings and mounting hardware.
