I've just tried to find the Youtube video, but no luck so far.
Basically, you just undo the three hex bolts at the truss apexes locking caps on the secondary end and remove the top cap section and truss ball joints, undo the Dovetail which is bolted to the secondary ring, and rotate the ring 90 degrees then do everything back up. It does not fall to pieces
I'll continue to search for the video because it's well explained there.
