In 1985, the wings of a full-scale Cessna 207 aircraft were retrofit with Turbo Wing® Technology.
The plane was flown more than 100 times with significant results. Testing showed that the technology produced:
Level flight capability on rotors alone
Wing stalling non-existent
Lift per-shaft horsepower applied to rotors approximately 120 pounds per shaft horsepower at speeds as low as 30 to 35 mph
Excellent stability and control at all speeds, including high "Angles Of Attack" flight.
