This is REALLY a strange concept, hardly resembling a "helicopter", looks more like autogyro (or gyroplane). However, I wanted the minifigs and the price was good :) The final build is very compact, so definitely looks smaller than the Airship. Also, the whole foundation of it is made ENTIRELY of metallized silver pieces, I've never seen so many in one place in my life! :D There isn't a single grey piece in the set - everything is metallized silver. All in all, the set turned out to be much more interesting than I hoped.
Wings are a poor decision design-wise, though. They are bending under their own weight pretty fast and thus don't look that good.
Despite the plastic quality is lower than Lego, all Winner's minifigs ARE AWESOME. I love cyborgs (or pirates), and the "good guys" are not that simple, too!
