I am basically outgrowing my Hanger 9 Alpha trainer. I can do just about anything the plane can deliver, and have run almost 3 gallons through her. I am currently building a SIG Hog Bipe as my second plane, but it's gona be a while before she is done. I have been thinking about removing the dihedral from the Alpha trainer to give me better roll rate, and performance and prepare me for the flight characteristics of the biplane. Has anyone removed the dihedral on this plane, and has it helped?? Or am I just better off keeping the wing the way it is??? Let me know your feedback.
