RE: Ace Foam Wings
I have built combat style models using the constant cord wings for CL. Because they have a lifting airfoil they will turn much better inside loops than outside but if you allow for about twice as much down elevator as up you should be able to fly them. They make a fun sport model if you stick to inside loops. If you want to you can even use the tapered wings to make simi-scale profile WWII models but will probably want something like the Norvel 061 for power if you use them full length.
