Here is a cool manuver to try. Just make sure your airplane is built well.
Go up high and at idle give these comands. full right rudder at idle speed. Full up and right ailoron. Let the plane spin several times and then slam full throttle with right rudder still and down elevator with right ailoron. It will throw the airplane in a crazy spin. I have done this with a Magic and another small plane that someone designs at our field. Try it and let me know what it does with your plane.
