Ryguy - Yeah, I've flown it about 7 or 8 times this week since finishing. I think it's great. It flies like it's on a rail. I keep in mind that it is a lighter version of some 13 oz foamies and not as rugged, but I think the Extra is a great flyer. I don't know anything about how the Cap 580 is doing, but I've caught wind of the same feeling - it flies badly. The Extra cruises on little throttle, hammerheads perfectly, knifes are bad, and rolls are crisp. I was wondering if the ones like the Flatana with the mid-wing knife better and how they track too. So far - so good.
