Basic UltraLight Motorized welcome to the world of low-budget flying
This flying wing looks sometimes expensive. But the basic
model is not!
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
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."
