Yes the D VII is draggy and low powered (don't know about the relative wing incidences), and I understand and can do coordinated turns. My question is why the seemingly backward differential works.
My buddy flew the airplane all afternoon yesterday and it looks much more "coordinated" with the reverse differential. Just doesn't make sense to me!
Good chance the reason it works is because of what Dick has mentioned. Draggy and low powered really does cause the wing to need to create more lift. And it does it with AOA. And we really don't know for sure what shape the ailerons are in for effective work. But our models usually are not dragging about. So they're usually not going into the turns like this one is.
There is one thing we can assume. If it is working, it's doing it by either lessening drag over what was a higher drag situation on the outboard wing, or increasing drag over what was a low drag situation on the inboard, or both. Those are what caused the problem in the first place.
