> game controller to steer sub People keep picking on this point, but if you have a backup controller, and a safety system that is independent of the controller (I've heard the sub had a way to resurface without the controller), then it's fine. (You also need to make sure you won't do a 360-backflip-barrel-roll if the controller firmware has a bug.) Bought your interior lights from Harbor Freight? As long as there are multiple independent lights, as well as a safety system to resurface that doesn't require lighting, then it's fine. Of all the cut corners, the game controller isn't what killed them. Unfortunately, they cut corners on the hull too, and there's no backup for that.
