I would love too see this puzzle mass produced - as would many other of your viewers I'd suspect! Yet again, another wonderful puzzle from Eitan - fabulous!

I'm thinking about approaching some companies.

Wow. I never even considered how the lack of an edge piece on the curvy copter 2 could complicate the solve. I always assumed it was just a CC3, but without edge to guide you. I was wrong :)

That insight at the beginning just exploded my brain.

In fairness, the insight came from (take a guess!) Brandon. He wrote something about it briefly on TP. Hopefully I helped flesh out more fully what he said (plus it's easier to see what's going on looking at a physical puzzle). But I agree, it's so cool to think of how just changing the shape of the puzzle can change something like that.

Awesome. Gotta love this wonderful community of nerds we have!

It never ceases to amaze me the uses you can put the mighty corner piece series to. I could never have worked out how a corner piece series would apply to an octahedron.

Fascinating puzzle

Oof, those 4-move setup sequences for the corner wings are going to do me in. Lots of opportunities to accidentally re-scramble. 😂

I was right. My third corner wing placement took a wrong turn, and I ended up starting waaaaay back at the corners. 😭 I'm back at the corner wings again now, and I'm being more careful. But gah, it's hard to set things up!

You think the 3-4 move is hard? Apparently the method Brandon (and Julian) were talking about had setups of 10 moves...

Could you give me a hint about how you came up with the 14-moves series to solve the edge wings? I wish I could find my own😂

Well, first of all, pcubes is your friend. I'm assuming you have it but if not, you should get it. Let me know if you don't know what I'm talking about. I will often use pcubes and just experiment and see what does what. However, in this case, there are two interactions you can have when you turn two adjacent edges. In one, the two edges are "opposite", eg L and R, and the only piece intersecting are the corners. (In other words you can just use LRLR to 3-cycle corners). The important thing is that on the L and R edges, the wings are untouched. On the other hand if you did, say, LBLB, you find there's an intersection of more than just corners, in fact, every piece type interacts, so this one is no use. OK, so I'll look at the LRLR. As I said, on these two edges, the edge wings are untouched. However, notice that on the front edge, the upper edge wing has been changed, but (and this is the key) nothing else on that front edge has been touched [apart from corners]. So the theory then is to move that changed edge wing out of that position and store it somewhere else. To do this I do BFB. What this does is move that "changed" edge wing to the lower spot, and put a new eedge wing in its place. Then we undo the LRLR by doing RLRL, and finally we undo the BFB by doing BFB. The reason we get a 3-cycle is that the key move of BFB, which changes the position of the affected edge wing from upper to lower on that front edge, does not affect anything else. That's the way any commutator is created. AS another example, the corner piece series on a cube. U R U' L' U R' U' L. The U R U' puts a different corners into the UBL position. Before, the cube was solved, but now, the left face has one (and only one) piece which has changed. So we move this corner out of the way using L'. Then we undo the moves. We undo the U R U' by doing U R' U', and then undo the L' by doing L. Essentially the same thing as on the ETO. I realise this is a long answer but it's hard to explain things in writing. If you need me to make a short video I can.
