Classic Curvy Copter, not that special to be honest, and not even that fun to solve. It introduces - along with the helicopter Cube - a feature called «jumbling» which is a totally other way of swapping pieces from a face to the other one(s), but still: the colors are not that beautiful, it doesn't turn smoothly enough - or, at least, not good enough to avoid you swearing - and overall once you solve it... You solve it. I personally don't find it that attractive, but it's kinda unique so I suggest you give it a try.

Very good Curvy Copter. It comes lubed but in some cases you have to adjust the tension (remove the corresponding axis piece to reach the screw).
