Rock,

To your post #10, I'll stick by Jim T's description. Except for some very small, intentional stab trim angles built into the models of a very few CL stunt fliers of National and World Class caliber, stunt models are rigged with 0-0 incidence (decalage, whatever you wish to call it.) To get a lifting AOA, the wing needs a very slight pitch "up" in the direction of the required lift. The entire model makes that pitch rotation. Elevators and interlinked maneuvering flaps contribute, yes, to achieve that net "positive" AOA.

The reason it is not evident to onlookers, except that it looks different when the model is flying inverted, is that CL stunt models are capable of dozens of g's lift. Proportionally more, even, than the RC 3D and "Fun Flyers" since one objective in flying a high scoring CLPA pattern is to maintain velocity as nearly steady as possible.

With that capability at the extreme, 1.0 g flight clearly needs very little AOA - but it needs some!
