In case you missed us at Oshkosh this year, I thought some of you might be interested in a picture of our MW Fly powered Sonex.

Hope you like it.

Looks nice, but what’s the go with the tiny intake for cooling in the cowl?

They are liquid cooled engines. If you look at the lower cowling you can see a large rectangular cutout for the radiator. I talked with them at Oshkosh. It is a very cool engine with fuel injection and a fadec. The down side was that they were in the 20k+ price range not including things like the prop, engine mount, cowl etc. They do meet the 200lb weight restriction specified by sonex.

Hi folks, thanks for the interest.

The engine is the B22d, ungeared, 100 hp. We remapped the engine to put out 106 hp and rotated the air intake pipes back and down in order to fit (almost), the Sonex cowling. There is a little bulge on the top with a small NACA inlet in it for the FADEC unit. Cruises is 118 knots, top speed 126 knots. These numbers were on day which was pretty close to standard atmosphere and at a gross weight of 1150 lbs. I think we could use about 2 inches more pitch on the prop but otherwise the performance is not bad. Climb at full gross weight of 1150 lbs is about 950 fpm. At aerobatic weight it is about 1150 fpm.

Note for Brett, the little intakes serve almost no purpose. Although they do allow in a small amount of cooling air. As the engine is totally liquid cooled, the prime reason for them being there is to allow access to the pins in the piano hinges holding the cowling on

Note to Keith, the weight is a little bit over what the folks at Sonex would prefer. We pulled the engine in as tight to the firewall as we could. When empty, the center of gravity sits right on the forward limit so any weight we add moves it aft. All in, including prop, spinner, all accessories and fluids we are about 223 lbs. This is an installation we wanted to do as we are fans of the Sonex and one came available in our area. At this time it is not an installation supported by Sonex. As a result, we tend to refer to the plane as the “City of Milan”, as an homage to the engine’s place of origin and out of respect for the good people at Sonex.

Cheers!

Here is a little video clip from back in May. GVNZ at our home base in Carp, Ontario. 150 mph on the clock. It is turning out to be quite the little hot-rod.
