Nice! The arms have that weird double-joint, in the instructions they have a photo to explain it, that's how odd it is. I'm surprised you have trouble with the back panels, my guess is you're not flipping the part ahead of it up first as that's what I ran to, otherwise pretty easy to do IIRC.
JT -- I transformed SS from bot mode to jet without instructions a few days ago. (Proud of myself -lol). The arms folding underneath were the trickiest part I thought. The back panel with the top fins didn't want to go down, but it barely goes into place now.
Pretty much that's it, Bran doesn't have a CELLPHONE, if you can believe it! Los Angelino without a cellphone may as well be a Martian. :D He'll be at the Transformers panel probably though, and is doing our 5:30 get together.
Crunchy, fig & all other CC attendees -- I'll be at the con all of the days. (not long sun. though, dunno yet). Hit me up. Text or otherwise. Hmmmm....how to get a hold of Figrin Bran? Hold a sign w/his name?? :p
