A big ship I made in Gmod, mostly using wiremod, and a couple PHX models. It goes up, down, forward, backward, turns, and drops 4 bombs all controlled with WASD, shift and the spacebar while you're sitting in the cockpit (You can see all the wiremod stuff for the controls on the back of the seat). As you can see there's a screen on the inside that shows the render target camera that follows on the outside behind the ship, and for the video I used a camera to show directly underneath when I drop bombs.
Right now I'm working on some manned turrets to go on top of the two sides, the seat will pivot around in a circle and hopefully I get get them to be aimed with the mouse.
