B300

DESIGN: UniCopter ~ Power Train - Reduction - Primary

Outside Helicopters

Helicycle:

B.J. Schramm feels that the engine firing impulses are isolated from the transmission by V-belts. He also feels that a cog type belt is too stiff. Note:- He is probably referring to a 2-cylinder engine also.

UniCopter

The primary reduction will be by V-belt, as is done by the Robinson R-22, Schweizer 300 and Helicycle. This will reduce the transmission of engine vibration and allow for a simple soft start.
