This is my variation on Adam G. Cowans excellent helicopter cube. In this version, the cuts are curved so that the orientation of the internal centerpieces can be seen, making the puzzle much more difficult. The rotation of this puzzle is very smooth and stable. It is a great looking addition to your collection as well as a nice solving experience.
