Extras, Extras seems like all you see is Extras. 25 years ago aviation pioneer Walter Extra made history by flying an aircraft that literally changed the aerobatic world, not to mention the industry. It was 1981 when the manufacturing engineer and German champion pilot completed and unveiled the first EXTRA to the world—the EA-230. Over the years, Walter Extra and his select team of engineers have built and certified seven different aircraft, making the most significant aircraft design breakthroughs in a generation. Today, pilots around the world consider Extra aircraft a superior choice. The order of invention of the Extra is: EA-230, EA-260, EA-300, EA-300S, EA-300L. The numbering system is the horsepower of the 6-cylinder Lycoming Engine. The original Lycoming 540 cu in engine put out 300hp. Now it puts out 330 hp, but the name of the aircraft has stayed the same as far as Walter Extra is concerned. Some pilots have named their planes Extra-330, but that is their own designation. 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.

The EXTRA 300L is a two-place, low wing monoplane powered by a 6 cylinder, 540 cubic inch, 300 HP Lycoming engine. The propeller is three-bladed and made of lightweight composite materials designed and built by MT of Germany. The EXTRA 300L is FAA certified in the acrobatic category and can be flown to plus or minus 10 Gs. With almost full-span ailerons, the roll rate on the 300L is greater than 360 degrees per second. This, coupled with the high G rating, makes it one of the most agile two-place aerobatic airplanes in the world. Top speed is 250 miles per hour. The secret of the strength and agility of the 300L lies in Extra's advanced design concept utilizing high strength, lightweight composite structures. The wing spar is made from a carbon fiber/epoxy material that assures a large safety margin even at 10 Gs. The skin of the aircraft is more than 90% composite allowing for a high gloss surface finish and a very low value for parasitic drag.
