20x10.5E Wooden Propeller for Electric Models - Bolly BLW20105E  [BLW20105E]

High-precision wooden propeller for pattern flight

This wooden RC propeller follows the Bolly BLW20105E specification, sized 20x10.5E and styled for pattern and sport electric aircraft. It is sold as a single replacement blade for aircraft that require a 20x10.5E propeller and where shaft and spinner compatibility are confirmed.

Installation notes: check spinner and shaft fit carefully before installing, confirm blade rotation is correct for your motor, and use the correct hardware to secure the prop. Balance the propeller using a reliable balancer or supported method to keep vibration low and protect onboard electronics.

Flight tuning: switching to a 20x10.5E wooden blade will alter the propeller load and aircraft response relative to other sizes or materials; expect changes in RPM and throttle feel that will require trim adjustments and possible ESC calibration. Use incremental testing to settle on the best setup for your model.

Storage and care: inspect the blade for splits, chips, or glue line failures before each flight, store on a flat surface away from moisture, and avoid exposing the prop to rapid temperature swings. Replace any prop showing damage to maintain safe and predictable handling.
