Guess the anime Screencap: Revisited

I'm not sure how much of a bigger hint there you could give since you've already presented us with a picture of some of the actual robots in the show.

The problem with non-Gundam mecha shows is that if you've watched a couple episodes of a couple of them, you're unlikely to remember them. In my case, I watched anime in Hong Kong when I was young, so the name of the show was translated, and since I was incapable of reading hiragana or katakana letters at the time, I have no idea what it's real name is. That problem applies here, except I don't even remember the Chinese name, I see the feet, the plane, the robots, they all look familiar. But having seen so many random episodes of random mecha shows, it's all kind of a blurb.

Jam it back in, in the dark.
