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

Durable wooden propeller for electric sport models

The Bolly BLW20105E wooden propeller is a 20x10.5E blade crafted for F3A-style pattern and sport electric aircraft. It is supplied as a single unit and intended for models accepting the 20x10.5E dimension, providing the characteristic damping of wood construction.

Installation tips: confirm the prop bore matches your motor shaft or adapter, check spinner clearance at full rotation, and secure the blade with suitable nut and washer. Always balance the prop before flight to reduce vibration that can accelerate wear on bearings and airframe components.

Effect on handling: a 20x10.5E wooden prop will change the aircraft's prop load and throttle response relative to other blades; expect differences in RPM and current draw that affect handling and component temperatures. Adjust trims and monitor motor/ESC temps during initial flights with the new prop.

Care recommendations: examine the blade for chips, cracks, or delamination before every session, keep the prop stored flat and dry, and avoid exposing it to rapid heat or moisture changes. Small cosmetic nicks may be sanded out, but any structural damage warrants replacement.
