APC AP20011E 20x11E Electric Propeller for RC Models  [AP20011E]

20x11E Performance Electric Prop

The APC AP20011E is a 20x11E electric propeller intended as a replacement or tuning option for electric-scale RC models. The designation shows diameter and pitch and the electric marking, and the blade profile is optimised for model-level thrust and efficiency rather than any full-scale application.

Fitting is simple for models that accept this prop form factor: mount the prop to the motor shaft or the prop adapter that came with your model, verify correct rotation direction for the motor, and secure it with the matching nut or retaining system used by the prop hub. Always perform a static balance check and a short run-up at low throttle to confirm there is no excessive vibration. If you detect vibration, remove the prop, clean the mounting faces, and rebalance before flying.

When used for tuning, a 20x11E changes static thrust and cruise behavior compared with other diameters and pitches; swapping pitch will alter torque demand and RPM for the motor and ESC, so monitor current and temperature during trials. Use this prop as a direct replacement or in stepwise tuning changes, recording motor and ESC readings to keep components within safe limits.
