Electric RC Wooden Propeller 20x10.5E (F3A Pattern) - Bolly BLW20105E  [BLW20105E]

Balanced wooden prop for electric RC models

This wooden RC-scale propeller is made to the Bolly BLW20105E specification, measuring 20x10.5E and optimised for F3A pattern and sport flying. It is intended for electric model aircraft that accept the 20x10.5E size and is supplied as a single replacement blade for hobby use.

Installation notes: verify shaft diameter and spinner clearance before fitting, set the rotation direction to match your motor, and secure with the correct nut and washer for the airframe. Always balance the propeller on a dedicated balancer or supported axle prior to flight to minimise vibration transmitted to the airframe and onboard electronics.

Tuning role: fitting a 20x10.5E wooden propeller will change prop load and throttle response compared with other sizes or materials; expect altered RPM and throttle feel that influence trimming and motor/ESC thermal behaviour. Introduce this prop during stepwise testing when adjusting motor and ESC settings to reach the desired handling.

Care and inspection: inspect for cracks, chips, or delamination before every flight, store flat and dry, and avoid sudden temperature or humidity swings that can warp wooden blades. Replace the prop if any damage is found to preserve predictable handling and protect the motor and airframe.
