Unbandged Helicopter Skewb

This is the Unbandaged 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.
Unlike the normal Helicopter Skewb, this puzzle has some unbandaging (similar to the Curvy Copter plus) which makes it even harder to solve. You can also buy the regular (bandaged) Helicopter Skewb.

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.If you order this model, you will get a DIY kit of the plastic parts needed to make this puzzle. You will need to supply your own screws (M3), stickers and springs for assembly.
