The
Extra 300S
is a purpose designed, unlimited aerobatic
competition aircraft. The
Extra 300S
is one of a handful of types capable of
competing effectively at international level and
one of very few to have achieved a US Federal
Aviation Administration Standard Category
airworthiness certification. It is the
culmination of nearly twenty years of design and
construction technique development by its
designer, Walter Extra.
The
airframe, designed and constructed to cope with
loads of plus and minus, makes optimal use of a
range of materials in its construction. The wing
and tail are built of state of the art carbon
and glass fiber composites while the fuselage
uses steel tube in a construction method used in
aircraft manufacture for more than eighty years.
The wing skins are supported by wooden ribs
attached to a pair of carbon fiber wing spars.
The fuselage is covered in a combination of
glass fiber panels and synthetic fabric.
The
300S
differs from the 300 in having a single seat,
shorter span wings and more powerful ailerons,
while retaining the same powerplant and basic
fuselage. Extra 300S are stressed for +10/10g
flight with a single pilot, have additional
transparencies in the lower sides of the
fuselage below the wings for pilot visibility,
and a single piece canopy.
