RE: Yak 55 3d flightflex or U Can Do 3d flightflex
I wouldn't buy either. I've flown them both, and they do not fly very well, and contrary to what you would think, they aren't very durable either. The fuse sometimes rips when it bends, and will need repairs, which just keeps adding weight. They are just a frustrating experience. You'd probably be better off looking at a regular foamy, they fly better, longer, and are more durable.
