Normally propellers are multi-blades but the simplicity of a single-blade propeller fits well on motorized gliders, because it permits the design of a smaller aperture of the glider fuselage for retraction of the power plant. The counterbalanced teetering mono-blade propeller generates fewer vibrations than conventional multi-blade configurations.
Propellers typically consist of multiple blades, but a single-blade design is suitable for motorized gliders as it allows for a smaller fuselage opening for engine storage. Additionally, the counterbalanced teetering mono-blade propeller generates fewer vibrations than typical multi-blade configurations.
