Bolly BL3L1007 3-Blade 10x7 Wooden Propeller for Electric Models  [BL3L1007]

Wood Laminate Propeller Guidance

The Bolly BL3L1007 is a laminated hardwood three-blade propeller in 10x7 size, intended for electric models that accept 10x7 three-blade fittings. Laminate construction brings predictable stiffness and a traditional scale appearance instead of the ultra-light feel of composite blades.

To fit, ensure your hub or spinner accepts a 10x7 three-blade assembly, confirm correct rotation, and secure using the appropriate spinner or nut for your shaft. Always check alignment and clearances around the cowl and fuselage before powering up.

Balancing and careful trimming are essential. Use a static balancer, correct tiny heavy spots by sanding the rear face only, and re-evaluate until the prop is balanced. Note that small changes in blade mass affect motor load and vibration, so run a brief power check to confirm temperatures and handling after installation.

Safety guidance: remove the prop when handling batteries or doing setup, inspect blades for cracks or delamination before each flight, and replace at the first sign of structural failure. Use the correct nut or spinner diameter and threadlock as recommended by your airframe.
