my first tri-plane had to be the famous Fokker-DR1, very hard plane to land, landed once on sand out of lost count trying to land this plane, i have intergrated my 12 cylinder radial engine into the fuselage to make it look like the DR1, the plane levels out at high speed, 160+ mph, nice flight control, i did have the perfect shape on the tail, had to change to create a better yaw stabillity, the tail still swings a bit, this p[lane is famous for the german pilot known as the red baron who was feared by most pilots who come up against him, i cant see how a small plane with such a large wing placement and vertical yaw control can even fly, this plane has bugged me for about 3 days trying to get the flight controls balanced, ive got plane to the best i can for controllabillty
