How is that a bootleg Jetfire? Between the VF-1A inspired head (rather then the VF-1S head that Jetfire had) and the various markings (including Skull markings and UNSpacy kite logos) it is clearly a bootleg Macross Valkyrie. Yes, it has red fast packs, which might seem more Jetfire-ish, but bootlegs are often known for having wonky colors.
That'd be like identifying these as bootleg Jetfires:

They're not made by Hasbro or Takara, the coloring is all wrong, they're a different size then the original, and they have different heads! (Oddly, though... where as usually, bootlegs feature simplified molds, these are kind of the opposite.) This "Yamato" company had some balls doing such blatant Jetfire rip-offs!
Without the obvious Macross-ish markings, or if it had a more VF-1S-like head, or if it came in packaging that tried to look like Transformers packaging, I'd go with calling it a Jetfire bootleg. But looking at that, I don't see anything that says Jetfire to me. Even with the red fastpack. I just see a cheep knock-off Macross Valkyrie.
