UniCopter ~ Power Train

Overview:

A self-contained assembly? See Assembly for potential configurations.

Some of the following pages have information on the old lighter UniCopter and must be revised.

NOTE: ~ The final gear arraignment may not be possible. The Flettner, Kellett and Kaman final reductions have the pinion gear above the crown gear. In other words the angle between the centerlines of the gears may have to be the other side of 90º.
