New Engines, New Instruments from MW Fly and PAT Avionics at AirVenture

Oshkosh, WI – MW Fly will be introducing a new line of Aeropower engines rated from 115 to 150 horsepower at AirVenture. Developed and manufactured in Italy, the new engine line is water-cooled and features electronic fuel-injection, integrated reduction gear, dual fully redundant ECUs.

The engines also include new engine-monitoring instruments developed by P.A.T. Avionics. The HSA-M engine health status annunciator provides comprehensive information on engine temp, oil pressure, fuel pump, battery, generator, and ECU health. It even tells the pilot when the engine is ready for takeoff.

According to Tony Watkin, President of Bush Caddy: “The new MW Fly geared and fuel injected engines with their powerful Health System Annunciator by PAT Avionics are a prefect option for our aircraft.” The Canadian aircraft kit maker is the first company to offer the new engine and instruments in North America.

PAT Avionics has also developed a new PROP-M electro-hydraulic prop governor that automatically sets prop pitch for best performance in all flight phases for experimental aircraft. If preferred, the pilot can select manual override for prop settings.

MW Fly engines have already been successfully mounted on a number of experimental aircraft and rotorcraft in Europe, Russia and South Africa and have proven reliable and efficient. The engines and instruments will be on display at AirVenture at booth 459. For more information visit and
