The octahedral equivalent of the Curvy Copter II.
The name reveals the puzzles nature. Its axis system is geometrically identical to that of an edge turning hexahedron. The pieces are identical to those of the Curvy Copter II. There still some differences in solving: The corners of this puzzle have a visible orientation compared to the faces of the Curvy Copter II to which they are equivalent. The faces of this puzzle have no visible orientation although the corners of the Curvy Copter II have. There are more slight differences for the other pieces.
Since this puzzle has the same axis system as the helicopter cube (and its relatives lik the Curvycopter) it share another property with it: It allows jumbling moves.
Face to face distance: 57 mm (standard 3x3x3)
