RE: FOAMIE WIND LIMITS?
In my opinion, you can fly any of the low wing planes in lots of wind....it just depends on your skill and how much you want to fight it.
Personally I like a little wind. It makes it fun for hanging it on the prop. And it makes you fly the plane. For 3D, as little wind as possible. Its a pain to hover when its gusting.
Ideally, no more than 8-10 mph for a depron plane (youll be fighting it though). If your flying a styrofoam formed plane such as a formosa or something simular. It should cut through the wind like any balsa plane should.
