The only one I built I had a wing tube set up for a two piece wing of my own design, it worked out great for me. Then I let my friend/basic instructor fly it and he started doing big loops and flat spins with it. The wing folded on a flat spin. Yes, I was ticked off!! It's just a big floating glider with some small power up front, not an Extra or Sukhoi. I built it for those after flying days so I could just sit in a chair and watch it float around, I would like another one but that one was the only one I built. Any good micro servo is OK in this plane. Unless you plane on stunting it a lot??
