You can see some TF parts in there. But for the most part--at least in regards to the outer shell--that's new work. T-Rex looks awesome! Almost exactly how it looks in the cartoon.
Fantastic, this looks even better then the (1980's)scratchbuilt store display that I saw on auction in the spring. It seems to dwarf d*mn near every (dino)bot/con made....
The only thing is that the "wings" are a bit lower on the back in robotmode(seen from he gallery), but that doesn't detract from the awe inspiring aspect of this bot.
thats fu#king awsome. Totaly unexpected. I havn't looked here for a while and now swoop + grimlock on this huge scale. I can't tell whats in it either.
