Yes to both questions lol. To be honest this puzzle is pretty simple if you can solve the helicopter cube, which is tricky, but not extremely difficult to figure out by yourself.
And There are 189 puzzles on gelatinbrain, and I've solved ~50, so yea, there's a lot I can't solve
Edit: Solving this (at least with my method) is almost exactly like solving a megaminx while knowing how to do a 3x3. There are some differences, but it's pretty much just an expansion.
Thanks, but it isn't as cool as it seems. Try giving this puzzle a try, and try to make some headway. If you can get this, then the CopterMinx isn't that hard.
