nice design on the catapolt!! I like the way you used the "space" cockpit to hold the 2 x 2. I to was wondering if the string detaches or just unwinds. I would have thought that the pressure might break it.
Might I make a susgestion? Not sure historicly, but most of my catapolts are pulled by horses. They seem a good way to get something that heavy around. I noticed that there are two "arms" down on the sides. Guessing they are for men to push it. Maybe you could use some sort of hitching on it... anyway just a thought
here are two ideas...
Long, long ago. In a galaxy far, far away... THERE WERE CASTLES!!!!!
