This was actually a re-release of the much earlier Plarail C-12 using a AA battery and much more resembles the real thing. The earlier renditions of the C-12 by Plarail used 'C' sized battery's and because of that they had to make the model engine much fatter. You can see the earlier renditions in Ucwepn's video here where he shows 3 of them. I didn't know until the re-released C-12 came out that the real one wasn't fat like the earlier versions. I actually like the fat ones better as they look more 'Beastly' LOL.
