What You Should Know About the MWFly Engines from Italy

Guido Fantini offers a detailed look at the MWFly four-cylinder aero engines being shown at Sun 'n Fun 2024. Available in two displacements (2.3 and 2.6 liters) and with or without a prop-speed reduction unit (PSRU). This two-valve-per-cylinder isn't based on any automotive design, but has been purpose built for aircraft in Northern Italy. It also features liquid cooling and redundant ECUs for the fuel injection and ignition. The gearbox, when fitted, has its own oil supply and can be fitted with an electronic valve to permit the use of a hydraulic constant-speed prop. The non-turbo version weighs less than 200 pounds with a gear reduction drive.

I was watching a 1950's movie and it was about an aircraft mechanic smuggling counterfeit bills. The engine in the movie was a 6 cylinder air cooled that looked exactly like the engines we use 75 years later. In 1950, flathead Fords were the hot setup, look how far car engines have progressed.

Looks to be a very well thought out design. 2 hp per Cubic inch is incredible. Water cooled and 4 main bearings. Those Italians love their fast engines. Great price too.

I am following this company for few years. Believe is a great solution. They are selling aeronautical specific engines since 2011 with more than 300 engines sold ! The great range of options from 100HP to 240HP (Turbo) practically allow the installation on most kits! What you guys know about this engine ?
