This new propeller system from Eddie Weeks will not only allow the pilot to change the pitch of the propeller during flight, but it is the only full reversible pitch propeller available for a 100cc gas engine. This will allow maneuvers never seen before on giant scale aircraft. Also tests are underway with the Futaba GV-1 governor to have a true constant speed propeller. It costs $650.
