Bolly BLW20105E Wooden Propeller 20x10.5E Electric (F3A Pattern) — Wooden prop for electric RC aircraft  [BLW20105E]

Wooden propeller for electric RC

This is a wooden RC-scale propeller offered under the Bolly BLW20105E designation, sized 20x10.5E and styled for F3A pattern work. It is intended for electric model aircraft that accept a 20x10.5E propeller size and is sold as a single replacement part for hobby use.

Installation notes: confirm the prop matches your motor shaft diameter and spinner clearance before mounting, set rotation direction to match the motor, and secure using the correct nut and washer for your model. Always balance the propeller on a dedicated balancer or by supported method before flight to reduce vibration transmitted to the airframe and electronics.

Tuning role: changing to a 20x10.5E wooden propeller alters prop load and response compared with other sizes or materials; expect differences in RPM and throttle feel that affect trimming and motor/ESC thermal load. Use this prop as part of stepwise testing when tuning motor and ESC settings for desired flying characteristics.

Care and inspection: check for cracks, chips, or delamination before each flight, store flat and dry, and avoid rapid temperature changes that can warp wooden parts. Replace if any damage is detected to maintain predictable handling and to protect the motor and airframe.
