The new AT-ST is an improvement over the 2016 release (75153) so far as details, but it still lacks hip and ankle joints that would allow it to actually be placed in a sturdy walking pose. Sure, you can bend the knee, but the result is a little awkward and unstable. This isn't a large or heavy model, and the Exo-Force ratcheting joints would suffice and allow for improved articulation. Or ball joints using the friction extenders. I don't know why they won't evolve this design, and pretty much the design of all their bipedal walkers, to have articulated hip joints, but they've been making their walkers like this for over twenty years and it just doesn't make sense to me why they show no interest in improving. Not the best, and not good enough. Too, like pretty much every System AT-ST set, this model seems to only accommodate a single driver. Again, with the advent of the UCS AT-AT looming, I would have hoped that associated Hoth sets would have changes to improve their accuracy to source. Guess not. My tone probably comes across as dour, but honestly, I'm more disappointed. I'm absolutely enthralled with the UCS AT-AT, and intend to get a copy- it has been the number one set on my Star Wars wish list since they obtained the license in '99, and I couldn't be more pleased with how well it turned out. I was fearful that the legs would be static, like the UCS Hulkbuster or the Ideas Voltron, both of which were exceedingly disappointing for that reason. So, the fact that they can be adjusted is fantastic and proper, especially in an $800 set. more to the point, LEGO is a multi-billion dollar, or kroner rather, annual earning company. They possess all the necessary resources, i.e. money, equipment, and extraordinarily talented people, to create new and improved joints for all sorts of applications, but for whatever reason, it is the one set of elements which seems to benefit least in improvements or additions. Given the number of mecha and creature sets they release, one would think that'd be an area they'd strive to improve in versatility, strength, and variety for all sorts of apps, but the reality is quite the opposite. That said, I do have to acknowledge that the new Constraction-like Iron Man set for 2022 has new socket joint bricks, similar to this: I'm cautiously optimistic that the new piece will have greater friction, negating the need for the friction extender piece which was designed for the Hero Factory line to compensate for unaided socket joints' low friction and subsequent inability to bear much weight without drooping or collapsing. It's something I've been hoping for, as the friction extender, while very useful, has the drawbacks of extending the length of the affected socket joint by one stud length as well as raising the profile around the said socket requiring more buildup around the joint to cover it, if need be. Too, sometimes they'll pop out of the joint they're reinforcing, due to the lower friction of the original socket. In short, it was a band-aid fix that LEGO employed years after the standard Technic ball and socket joint had been developed and the tolerances thereof established before they really started making larger models with them and realized that they lacked the requisite strength. But again, they have the resources to improve this deficiency, and all related joint deficiencies, and I continue to hope they will eventually. I really, really hope they'll revisit the Exo-Force clicky hinges and make some stronger versions that can bear more weight. Finally, a new System brick with an adapter to fit this as well as a Technic bit similar to this that will fit it and allow for ratcheting motion. Both would revolutionize what is possible with mecha and creature builds. Pretty please with cake, make these LEGO.
