HI SHERM172K! The change in AOA is diagramatical only, in practice when your flaps are deployed you should be able to fly around level with LESS AOA than if you were flapless. Try coupling the elevator to the flaps with a 10% mix and see how you like it, take note of how much better your plane can track through consecutive loops, and if you like doing spins your plane will hang in the air better. I have never seen this control sceme do anything but good on aerobatic models, I use it on everything from a GOLDBERG ULTIMATE to my little scratch built fun fly planes.
