Yeah, so checking the pics more carefully, it looks like they are reusing a lot of VF-171 parts.
As a result, there's a lot of things that are not lineart correct for the VF-17.
It's missing the VF-17's dual micro-misille launchers on each shoulder.
It's got incorrect VF-171 dual micro-missile ports on the inside of each lower leg.
Lower legs are way too skinny.
I'm sure there are other areas that are not lineart correct also.
