| History
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 fibre 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 fibre wing spars. The fuselage is covered
in a combination of glass fibre panels and synthetic fabric.
This aircraft was designed and built in Germany and purchased
by Tom Moon for national and international aerobatic competition.
Tom won the Australian Unlimited Class Championship in
1999, 2000, 2002 and 2003, after winning several first
and second places in previous NSW, Victorian and National
competitions. The aircraft can be seen regularly at the
Temora Aviation Museum Flying Days.
