I assume they were designed to unify by design as, well, that'd make more sense than them falling and happening to assemble into the Megazord, but at the same time it's not clear how/why/when they learned to form the Megazord. During the battle as things became more and more overwhelming I was wondering when someone (Zordon, Alpha, whatever) was going to tell them to "press the little red button" to form the Megazord.
I cannot greatly speak for the original show, but my recollection from it, aided by what I remember of the toys, but it seemed the Zords assembled in a way as to be "clear" on what vehicle was which part of the Megazord. With this Megazord it seemed like a lot changed and came out of nowhere in order to form the body of the Megazord, sort of the same problem the Transformers have with huge pieces of mass going/coming from nowhere.
Along those same lines, how did they know how to operate the Zords? It didn't ever seem to part of their training and it couldn't be they only learned once they were in them while in their armor because they had to learn a couple times how to do things, so when did they figure out how to drive them? And Alpha shows them off to encourage them and what's-his-face is able to just hop in one and drive off in it? Huh?! No locks on the door? No need to have the keys for it or a passcode to start it? No remote ignition lock-out from the main ship? He can just get right in and take off?
