Steve, I expect this is due to the high degree angle of incidence of the wing. The high angle helps to keep the coupe co-ordinated in a turn as the
"high wing" looses some lift (and drag), and accompanied by differential aelirons, therby resulting in coordinated flight. In a two control coupe, you just let it flop around. In an Alon, you might be able to control it somewhat, by use of the rudders.???? On the retractrable coupe - the angle was reduced considerable, and the wings redesigned to accomodate the retractable gear. Some ultralites have excessive angle of incidence, which alllowed turns without rudders. I think that makes sense. Harry 93530 Blacksburg, VA.
