Hello

I always wanted to know why we dont see any large pattern planes the fly with gasoline engines. I know that a 50cc would be to big to comply with rules but it would certanly make a great plane for practice and people that do not compete. A 30cc should come under 2m and 5kg and would keep operating costs low. I know the ys 170 is a great engine but it is expensive and at $25-30 for a gallon of fuel the operating costs increase dramatically compare to gasoline.

Happy Landings
