American Champion Xtreme Decathlon

The American Champion Xtreme Decathlon is the most powerful version of the 8KCAB Decathlon family, introduced in 2012 as a two-seat fixed conventional gear aerobatic airplane for training and competition flying. It uses a 210 horsepower Lycoming AEIO-390-A1B6 engine driving a 76 inch MT composite propeller, which needed redesigned, longer main landing gear legs. Other changes from the Super Decathlon are a new airfoil-section tailplane with 10 percent more area, clipped wingtips and greater aileron effectiveness. The manufacturer certifies it for plus 6 g and minus 5 g and lists a shorter wingspan of 30.9 feet and a service ceiling of 20,000 feet.
