Dyke Delta JD II
The Delta has retractable landing gear and the wings fold up and
over the fuselage for easy towing—no trailer required. The engine is
a 180 hp Lycoming O-360. Cruise speed is about 170 mph. The
windshield extends all the way up over the pilot's head which
affords excellent visibility. Airframe construction is largely
welded steel truss with a fibreglass skin attached with flush blind
rivets. Notice the shape of the upper surface of the fuselage—the
fuselage provides significant lift! More than 400 Dyke Delta plans
have been sold and there are about 45 flying today with another 15
or so still in active (or semi-active) construction.
