Bolly BL3L1107 11x7 Wooden 3-Blade Propeller  [BL3L1107]

Bolly BL3L1107 Beech 3-Blade Propeller Overview

This Bolly BL3L1107 is a three-blade wooden propeller sized 11x7 designed for RC-scale aircraft applications. It is offered as an aftermarket wooden prop suitable for models that accept three-blade hubs, delivering a different thrust curve and a scale look compared with two-blade options.

Installation emphasizes correct hub seating and secure mounting: make sure the prop sits flush on the spinner or hub, tighten the prop nut to your airframe manufacturer's recommended torque, and confirm shaft alignment. After fitting, perform a static balance check and remove small high spots to reduce vibration prior to flight.

From a tuning perspective, this wooden three-blade can modestly shift thrust and response; beech blades often dampen certain harmonics and show predictable wear. Use the Bolly BL3L1107 when testing pitch changes, matching prop choice to motor and gearing, or when you want a lightweight, cost-effective prop for scale or sport flying.
