>>8629007i just realized that i never posted the pic of the built thing.
Its a nice kit, but its rather small and the tracks do not run perfeclty.
It has a "hand of god" wheel at the back of the vehicle to elevate the gun.
Besides the tracks my major complaint would be that the clutch of the bricks for the gun, or rather the technique how it is built, is rather weak.
But that is more an issue if you are playing with it and not really a problem if its standing on a shelf.
