Rotormast V-22 Osprey – Part I

I was a Marine in the 70s, and had the good fortune to be assigned as an Avionics technician on the AV8A Harrier. I was responsible for the maintenance and repair of the "Autostab system" which while not officially an autopilot, was there to help the pilot maintain safe hovering flight. As a result, any modern model that can transition from hover to forward flight, (and back), is going to get my total attention! Not to mention that the V-22 is the current state of the art deployment method for Marines in the field. This model was a must for my interests and passions!

Tom Mast invested four years into the engineering and testing his V-22 scale model and then formed Rotormast, LLC to distribute this machine. Tom's knowledge of tilt rotors comes from his career as an engineer at Bell Helicopter in Texas, where the full-size V-22 is designed and built.

O.S. Engines 55HZ-R

The HZ-R shares the exact same specs as the popular 55HZ-H but adds the OS Demand Regulator System (DRS) at the fuel inlet to supply fuel based upon the engine RPM. The DRS uses crankcase pressure coupled with a check valve to pressurize the fuel supply creating a high-pressure system that provides constant supply of fuel, unlike like fuel systems that utilize muffler pressure that change as the tank drains.
