Yeah, it's a Hase kit, I forgot to say that. Well I know that you can get a weapons kit, but I thought that some of these kits came with the Super and Strike Packs, and missiles like the VF-0 comes with its FAST Packs. If I'm under a rock, it's because I've never built a 1/72 Valk, just those tiny 1/144s from Macross 7. And on the kit's instructions, it doesn't quite say that you can bore out the holes to place pylons on them.
FYI, you need to buy the weapons pack for pilots and munitions. You cannot however buy the fast packs separetly, if you want those you have to buy them as part of the super or strike VF-1's.
