Mitchelwing U2

Basic UltraLight Motorized welcome to the world of low-budget flying

This flying wing looks sometimes expensive. But the basic model is not!

Clearly visible is the wing configuration: flying wing, wingtip rudders, elevons. (Permission to use picture from Richard Avalon of U S Pacific)

U S Pacific describes the U2 as:

"The U-2 has high quality wood and aircraft fabric construction. The pilot sits in the wing, under a bubble canopy. This keeps him out of the weather and maintains the aircraft's sleek, streamlined appearance. In winter months, solar energy entering through the canopy comfortably warms the cockpit. In the summer the canopy may be removed and a fairing can be mounted.

The outer wing panels of the U-2 fold up along the main wing section, exactly like the B-10. This allows for the dimension-downsizing necessary for transportation via truck or trailer. At the launch site, it takes less then 15 minutes to prepare it for flight.

The U-2 is comfortable in front of a 20 horse power engine and together they weigh in at just over 300 lbs. But if higher performance is a goal, this aircraft can certainly entertain larger engines. Design features provide a stress factor of +/- 6 G's. Electric start and foldable prop can be added to make the U-2 a truly remarkable soaring machine.

Don Mitchell felt that the basic U-2 design could be home-built by the average airplane buff in about 350 hours, with perhaps another 100 hours required for the paint job, interior appointments and other conveniences not essential to the plane's flight characteristics."

Using a small engine, you can use it as a motorized glider. (Permission to use picture from Richard Avalon of U S Pacific)
