Three-Blade 12x6 RC Propeller Bolly BL3L1206  [BL3L1206]

The Bolly BL3L1206 is a three-blade hardwood propeller tailored for RC scale and sport aircraft. The 12x6 stamp denotes diameter and pitch; three blades influence thrust distribution and the prop's acoustic signature relative to two-blade designs.

Installation follows standard practice: mount onto the model's prop shaft, secure with the existing prop nut or spinner, and confirm there is adequate clearance from the fuselage and undercarriage. Ensure everything is tightened to eliminate play before flight.

Balancing and minor tuning are key to performance. Check the prop for cracks or loose veneers, and correct static imbalance through careful light sanding on the heavy blade. Balanced props reduce vibration and help maintain reliable handling and motor longevity.

Provided as an aftermarket spare part for RC aircraft, this prop should be used on models with matching hardware and within safe operating parameters.
