Ultra-powerful, high performance, frequently experimental and homebuilt Muscle Biplanes are flown in aerobatic competition and in airshows. Featuring high power-to-weight ratios, strength, reliability, and rugged designs the biplane offers the pilot a high degree of safety. 

Biplanes may be out of fashion. There is no doubt that uncommon pilot flying skills are put to the test mastering precision aerobatics in these machines. For this reason all those who fly recognize and respect accomplished biplane pilots. For akronauts who build and fly biplanes the personal challenges and rewards are beyond comparison.
