RE: Balsa vs. Foam
I make 3d parkflyers out of balsa and carbon. I also own my first foamy (ultrafly furious). The Foamy flyes alot slower and is better at hovering having less enertia then the wood built aircraft. The wood one is better for precision flying with 3d, it snaps far better and easier to keep on track. I would get both for when i dont have the two i miss the other one.
