In case anyone is interested, I flew this plane today...and it ROCKS!!! And the airfoil REALLY WORKS!!! Solid as a rock and suprisingly stable at full speed. Not a click...repeat...not a single click of trim was needed!!! Loops are so hard it chases it's tail, and actually retains forward motion while on it's back (Full pull). With conservitive stick movements, it flies great conventionally, and no hint whatsoever of any flex or flutter. Inverted is also very conventional. Where this plane really shines is slow flight. With throttle managment it can be slowed down to walking speed, and brought in for a perfect 3 point nose high Harrier landing with no forward motion or roll out. What a blast! I can't thank you guys enough (especially for the "stepped airfoil" link) for giving me the ideas for the funest plane I've ever flown. At a cost of less than $10 and an hour and a half to design and build it, the effort "in" compared to fun in return should be illegal! What a blast! If anyone's interested, here's some more on the plane
