The One Design is a single seat aerobatic monoplane specifically designed for aerobatics (recreational and competition). The DR-107 came about when monoplanes began to take over aerobatic competition. Dan Rihn decided to design a new aircraft to create a new class for the IAC (International Aerobatic Club). From there, the One Design was born, an aircraft that the pilot can build at a relatively low cost and fly competition aerobatics. The DR-107 One Design soon began proving itself with its high horsepower engine, fast roll rate and the ability to sustain very high G-loads.
