=== Extra EA-Series ===
The Extra Aircraft company designed several aerobatic aircraft based on the early experimental EA-230 and EA-260, followed by the FAR-23 certified EA-300 series (EA-300, EA-300/S, EA-300/L, EA-300/200, EA-300/LT, EA-330/LC, EA-330/SC). The company introduced the Extra EA-400 in 2001. This is a cross-country airplane with many exclusive features including carbon fiber construction, pressurized cabin, high strut-less wing, and a seating for six.
The EA 400-500 was introduced as a derivative of the EA-400 replacing the piston engine with a Rolls-Royce Model 250-B17F/2 turboprop producing 450 horsepower (340 kW) and driving a MT-propeller 5 bladed propeller. Walter Extra flew the first Extra500 from Germany to Oshkosh, Wisconsin to illustrate its range and capabilities. The most recent changes to the aircraft come from Avidyne with their latest glass avionics
, Entegra R9.
