The Curvy Copter is a variation on the Helicopter Cube. The cuts are angled in order to reveal the otherwise hidden centerpieces, which also creates the beautifully curved face pattern. Revealing the centerpieces makes the puzzle a bit more difficult as they need to be oriented correctly for the puzzle to be solved.
Just like the original Helicopter Cube, the Curvy Copter jumbles, enabling combinations which would otherwise be unattainable due to parity restrictions to be reached.
