ABSTRACT:
A method and apparatus to balance propeller blades including, but not limited to, those used on model aircraft provides relocation of the propeller's center mounting hole to the propeller's center of mass by installation of appropriate eccentric bushings into the center mounting hole, and preferably into an oversize center mounting hole that has been created in the propeller hub. Both spanwise and chordwise propeller balance can be made with this eccentric bushing method.
