Well... Damnit. I was playing around with my new Jetfire. I had a lot of trouble getting him lined up properly in jet mode -- nothing would peg in right! However, I got it close enough and kept playing. Then, while taking him apart for Prime, I noticed the foot wasn't articulating the way I wanted. It just would not sit flat. ... and on further inspection, the pin/joint for the foot is broken. Snapped clean through. It looks like the pin was drilled or inserted wrong. The other foot locks into place like I'd expect. Whelp. Back to Amazon you go.
