The one packaged in Battroid mode is the original VF-11, weak hips and all. It does not come with the FAST packs, but the FAST packs can be attached to it. The VF-11 that comes in fighter mode is the recently re-released version with FAST packs. The hips on this one are rock solid (knock on wood).
I second that! Don't worry, you didn't jinxed anything.
That by far the most durable and easiest to transform valk toy
compared to my YF-21 FP (not that my YF-21 FP got wrecked or somethin').
