Yep, I've already opened him up. Got him standing next to his two mates - Thrust and Ramjet, in my display cabinet.
I love the toy and my only gripe with it is the positioning of the wing under his arm - it makes it difficult to pose his arms because it kind of gets in the way.
I'll post some other pics soon when my Unicron arrives next week. Then I would have finished off packing both of my cabinets.
Sorry for the slow reply guys; spent the night with the wife and new baby so had no internet access. As you may have already guessed, he wasn't a local purchase so don't go crazy searching for him. I bought him off an online shop about 3 weeks ago. When / if you have the opportunity to pick him up, you won't be disappointed.
