20x10.5E Propeller for Electric Sport and Pattern Aircraft - Bolly BLW20105E  [BLW20105E]

Wooden 20x10.5E prop for sport and pattern models

The Bolly BLW20105E wooden propeller is a 20x10.5E blade created for electric model aircraft used in sport and pattern flying. It is provided as a single unit and intended for models that accept the 20x10.5E size, offering the feel and damping typical of wooden props.

Mounting advice: ensure the prop matches your motor shaft or adaptor size, confirm spinner clearance during rotation, orient the blade for correct rotation and fasten with the appropriate nut and washer. Balance the prop before flight to limit vibration that can affect airframe rigidity and onboard systems.

Tuning impact: changing to this 20x10.5E wooden prop will affect thrust, RPM, and current draw compared with other pitches or materials; anticipate changes in climb and throttle response and re-trim the model accordingly. Conduct progressive test flights while monitoring motor and ESC temperatures.

Inspection guidance: check blades for splits, chips, or loose laminations before every flight cycle, store on a flat surface away from moisture, and replace any prop that shows structural deterioration to keep handling predictable and avoid damage to the power system.
