Hi all, I'm starting this thread because I need a little help finishing the solve for my Ultra-X puzzle.

So far I have reduced it to a super x, and solved the super x portion, the only problem is that I cant figure out an algorithm to cycle the middle of the triangular faces (2x2 corners) without messing anything else up. Any help would be greatly appreciated. Below is a pic of the puzzle in it current state.

I'm not sure what would happen but you could try a corner 3 cycle for the 2x2x2. That would probably mess up the rest of it, but I think you should start with the 2x2x2 and then work on the Dino and Shallow Helicopter Cube parts.

I think this cycle need quite a long alg, because to solve them one must use 2*2 turn thus breaking the edge and center pairs. In my opinion, solve these 8 triangle parts first then pair up the center parts so that they could be solved with only dino turn(maybe the hardest step I guess,a 3-cycle is easy to find, but I do not know if it's enough) . Next pair up the edge and finally solve all with rainbow method. I do not know if there will be some special situation, so I cannot promise the success.

I agree with the others. Solving it from deepest elements to shallowest would work best. Does the 2x2x2 create parity for the dino pieces?

Where did you get the ultra-x?
