We've just added a conversion kit to our webpages to make our popular 15mm scale Siler Superheavy tank an anti-grav tank, adding considerable zip to the enormous Concrete Beast!
It's code TTC-2014 and is a straight drop-fit into the hull, crafted by the great Mark Mondragon for his handsome original design of our Siler Superheavy Tank kit.
Seen above are the pieces in the conversion kit. You'll need the Siler kit (available separately) to upgrade it to anti-grav status.
To read some in-universe background for the Siler mobility upgrade, check out this blog entry.
