RE: ACE foam wings
I would like to make a comment about the Ace wing. It does fly well but It has a bad tendancy to snap out inverted. I actually do not like this aspect but it is a lot of fun when you know how to use it. If I were designing a small plane\airfoil, I would either go symmetrical or less camber than the Ace airfoil to give better inverted flight. I have been out flying my simple ultimate all afternoon and it is a good example of this. It does not like to outside loop unless you keep the speed up and are gentle with the elevator. It was intetresting because I had just flown my Kaos and then the Ultimate. Big difference! The Kaos just has a better section I believe. At least for my tastes.
