All I did was tweek the Origanal version a little. I made is so it flies more scale. Slower turning, slugish pitch and more wieght. It flies compably similar to the real one I have seen fly before and it looks pretty omising flying in the distance. Its good landings since I have test landed it several times with extreme success. Its fun to fly and is perfect for formation fly in the 3D sim. Perfect for escort flying too. It flies about 220 mph. about roughly scale speed as the real ones flew too. Have fun.
