This Bolly wooden propeller is an RC-scale 14x8 three-blade unit intended for model aircraft where a wooden prop is valued for its finish and the option to trim blades. The three-blade arrangement affects static thrust and rpm compared with two-blade props, so swapping blade counts will alter handling and power delivery.
Fitment is generic to RC model aircraft prop hubs that accept three-blade props; confirm your prop adapter, spinner clearance and prop nut type before installation. Install with the correct hardware, tighten incrementally and verify there is no contact with the spinner or cowling.
Prior to first flight perform static and dynamic balancing and remove small heavy spots by careful sanding at the blade tips, then check balance again. Store wooden props in a dry, stable place to limit warping and inspect for cracks or chips on a routine basis.
