In 1994 METALWORK was founded by eng. Guido Fantini and eng. Stefano Marella. They are both are graduates of the Milan Politecnico in Aerospace Engineering. The goal of the company was to produce an engine for the L.S.A. (Light Sport Aviation) market.
The U10 engine project was started in 1995, which was a two cylinder 1000 cc engine 70CV. The project was presented in 1995 to the Light Sport Aviation show in Bassano (Italy) and then to Aero in Friedrichshafen (Germany) in 1996 gaining much interest. In 2003 it was set aside as the market had shifted towards more powerful engines.
In 2003 the B20 project commenced, a horizontally opposed engine with a displacement of 2000 cc / 2 liter. The project continued with great strides thanks to the experience gained during the U10 project and soon became the B22 with 2.2 liter displacement. The first flight tests were made in 2006. In 2011, after more than 2000 hours of bench testing and numerous hours of flight testing the engine had reached good reliability, making it ready for commercialization.
These engines are available in sixteen (16!) standard versions with power from 100 HP up to 155 HP, four cylinder horizontally opposed (boxer) direct drive or geared, left and right rotation, tractor or pusher, weighing less than 85 kg (187 lbs).
MW Fly Engines have been developed specifically for use in light aircraft and are manufactured to the highest standards. Standard equipment on their liquid cooled engines include an integrated oil tank, a dual ignition and fuel injection system, thermostat, water tank with pressurized cap, electric starter with relay, an alternator of 350W, shock absorbers and all sensors needed for the EMS system.
There are basically two engines regarding displacement: the B22 with 2.2 L and the B25 with 2.5 L. Each has a direct and a geared drive option, the geared version is available with two different gear reduction ratios. The A version is 1:1.731 and the B version has a reduction ratio of 1:1.958. The B gear version runs the crankshaft of the engine to a bit higher RPM (4700) for more power.
Below the common specifications of the basic engine models the MW Fly produces in their factory:
