The Curvy Copter plus is a Curvy Copter puzzle but slightly unbandaged so more moves are possible. It is similar to the Crazy Comet puzzle by Oskar van Deventer.
When jumbling the normal Curvy Copter you are quite constrained. Not only does the unbandaging of the Curvy Copter plus produce an even more interesting and beautiful face pattern, it also makes the jumbling feel less constrained. Solving this puzzle is extremely difficult, it can make amazing and confusing shapes. The Curvy Copter plus is the same size as a regular Curvy Copter puzzle.
Buying this will get you a DIY kit of the plastic pieces in either black or white. You will need to supply your own screws, springs, washers (M3) as well as stickers (www.dr-sticker.com). Alternatively, I can sell you an assembled copy directly for a small extra fee. To order an assembled puzzle or if you have any questions, please contact me at firstname.lastname@example.org
