I'm on the fence w/ Bandai's YF-21. I have four of the Yamato YF-21's. While those legs were insanely skinny on the Yamato, the fighter makes up more for that. If anything, I wish the main landing gears had a stronger lock-out mechanism (you know what I mean if you roll it backwards). If the joints were more secure and perhaps the legs heavier - as in metal, heavier, it could be perfect, or perfect enough for me...I wonder if metal legs would if affect the CG in battroid on a Yami-cadia one if it was to happen.
The Bandai version seems a bit clumsy looking in fighter tp my eyes.
If the landing gear was sturdier and better engineered, on the bandai, it might begin to sway my stance and start thinking about grabbing a few. The landing gear would be a start, but the Bandai one would have to dramatically raise the standard.
