I have just recently returned from 5 months travelling around the world with my girlfriend so havent touched this model until now.
The other day I got all the moveable bit animated and recorded a quick playblast to show what it can do. The link is below. (please excuse the awful camera work, have never moved a camera before!)
Hopefully I will have time now to start getting the whole tank moving around, I was thinking of trying to composite it onto a real road eventually, it will need someone to drive it though!
Let me know what you think.
