I see some foam planes are just that, foam and some have reinforced parts with carbon fiber etc. I was about to buy a 3D Buddy Edge 540 but then started looking more into the reinforced foam planes plus cheaper priced.............thoughts on them compared to stick built? I just don't want a wimpy flexable planes thats shot after 30-50 flights with minimal physical "abuse". The Great Planes models look pretty good..............I do outdoor flying, thanks!
