RE: First Fancy Foam?
My only suggestion is to keep it light. Basically use components comparable to the recommended components in weight. When foamies are light they fly great, the heavier they get the worse they tend to fly. I love foamies they are a blast. If you can handle ailerons, I don't recall the Goldberg Eagle II off hand other than I know it's a trainer, then on low rates most foamies will be fine. I have a Fancy Foam Ultimate kit here, it's a very nice kit.
I have not yet been able to fly it, but I just finished a 3D Foamy Advantage bipe. I think the 3D Foamy planes fly a bit better due to their G-Force wing design that incorporates a bit of an airfoil, but that only seems to effect traditional flight. In 3D flight the G-Force wings don't seem to matter as much. The Advantage I just built is not currently available as I recall, but the pics will show you the G-Force wing design and the very rigid design of their planes. I have pics in a thread on page 1 of this forum, just look down a bit lower than this thread.
Check out [link]http://www.3dfoamy.com[/link] before you buy. I think you'll be pleasantly surprised at their offerings. The Super series of kits are a good bit bigger at 45" wingspan, but only a little heavier and they handle wind better than most other foamies.
Good luck and have fun. Foamies are great.
