Lvl 5 Railgun
This is my flying crab sniper. I've gone through a couple versions, with this this being the final one. This bot is quite versatile. It has rudders in place of wings, so you can quickly fly to where you want to snipe, and then it has crab legs to provide a stable sniping platform. This bot is able to take a lot of damage and still be able to move. In the event that the legs get shot off, you are usually able to fly easily enough to get back to base or a medic. The rudders tend to be the last thing shot off. Oh, and since its so tanky and heavy, if you fly straight up, it'll stall. So don't do that.
