This is the Helicopter Skewb puzzle, which is a combination of the Skewb and Helicopter Cube puzzles. This puzzle has two very unexpected properties: it is possible to turn the Skewb puzzle by 60 degrees and still make Helicopter Cube moves, and it is possible to jumble the Helicopter Cube and still make Skewb moves. By using these and normal moves, it is possible to scramble this puzzle in to very hard to solve shapes. However, once the puzzle is restored to a cube, it can be solved using only Helicopter Cube moves.
This puzzle has a mechanism that builds a Helicopter Cube on top of a spherical Skewb core. It rotates very smoothly and is perfectly stable.
Please note that buying this will only get you the plastic pieces for building a Helicopter Skewb. You will still need to supply your own stickers (regular www.cubesmith.com stickers are good), screws, springs and washers. Alternatively, you can buy fully assembled and stickered puzzles from me for an extra fee. Please contact me at email@example.com for this service.
