This allows you to drive the cannon to the ideal location, before hinging down the legs and bracing for firing. You can also hinge up the front of the legs, as there are wheels underneath the cannon. I like it somewhere in between sideways and forward, a position similar to the one on the box. The legs of the artillery cannon can be hinged in and out. He has a printed 1×2 tile for controls, mounted on a clip connection. I think the only thing needed to make it more accurate is to lengthen the cannon barrel, but other than that it looks good! There is one seat for a controller, as seen here.
