I'm so glad I'm not burdened with extensive knowledge of aircraft technology. I just look at the pics and think "cool toy, I want one".
Don't get me wrong, I want the toy to be the best it can be, but I'm convinced Yamato would make the legs skinnier if they were able to. We haven't seen the battroid pics yet. Maybe when we see it in battroid mode we'll all praise Yamato for making it look so damned anime accurate.
