Honestly the entire figure has some rather bizarre design and build quality choices. For example the biceps are very tight but the tolerances are such that folding up the arms for jet mode forces the forearms away from the shoulders slightly which means the wing assembly has a much harder time remaining tabbed in place and holding the whole mid section of the jet together. And then you have the friction hip joints for swiveling forward and back which until tightened with some material are weirdly too loose to properly support such a heavy upper body. So his stability is somewhat limited until you do that. But then you get to the knees which are so insanely tight folding up the legs to get them nicely tabbed in is a little more difficult than it should be. Meanwhile the head-gun canon is a two piece assembly, for... no reason at all. Like I can't even fathom why on earth it had to be a head and a gun barrel and wasn't molded solid or glued together. And the shoulders are designed in such a manner they bump in to his back parts unless you move them out the way. I still like Jaegertron a lot, he's a tonne of fun and looks visually really freaking cool. But from top to bottom I don't understand how his design ended up the way it did when their are seemingly a tonne of obvious solutions to all of his minor drawbacks. It feels like it was done by some new hire designer and this is his very first project as apposed to a seasoned designer like cassy or grif, but I'm pretty sure they both had a hand in him.
