The
Extra Flugzeugbau
EA300 is a
two-seat aerobatic
monoplane capable
of Unlimited category competition. It was
designed in 1987 by Walter Extra, an
award-winning German aerobatic pilot and
built by Extra Flugzeugbau.
Design of the
Extra 300 was based on the Extra 230, an
early 1980s monoplane having a wing made of
wood. The Extra 300 has a welded
steel tube
fuselage covered in aluminium and fabric.
The mid-set wing has a carbon fiber
composite spar and carbon composite skins.
A symmetrical airfoil, mounted with a zero
angle of incidence, provides equal
performance in both upright and inverted
flight. The landing gear is fixed
taildragger style with composite main legs
and fiberglass wheel pants. The powerplant
is a fuel-injected
Lycoming AEIO-540
which produces 300 horsepower (224 kW).
The first
two-seat Extra 300 made its maiden flight on
6 May 1988, with German type certification
following on 16 May 1990. The single seat
Extra 300S flew on 4 March 1992.
The Extra 300 is
stressed for ±10 G with one person on board
and ±8 G with two. Some Extra 300s are
certificated in the Experimental Category in
the U.S., while others are certificated in
the Aerobatic category.
