Paul Andronicou Extra 300S Aerobatics

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.
