This plane is the foam electric var. of the Ultimate bipe. As such it enjoys better weight, scale and performance. It's at home in training new pilots in aerobatics of all levels even on low rates. It will afford the beginning pilot the ability to easily learn and practice scale flight and aerobatics. On high rates the advanced pilot's tastes are easily satisfied through all levels of his skills (aerobatics and 3D). Try it and see if you don't agree. There's a panning pilot cam on F4 for the cock pit aerobats among us. 'Hope you like it!
