Flakattack - Bane of the Plasma Bombers

About a month ago, Freejam released a weapon to help counter the current "OP" build: The Tesseract. It's a brick of the lightest blocks in the game, which still had high health for their weight, making it maneuverable and tanky. 

The weapon is a two-barreled flak cannon that shoots one projectile every half second. When the projectile gets close to a robot that is not touching the ground, it explodes, usually doing a great deal of damage.

So since the release, I have tried it out on a few robots with varying success. My first bot is a semi-triforced tank with two cannons.

It works quite well, and I'm satisfied with it. However...I thought I'd take it a step further, and make one of those guns fly.

Now this was tough to get right. The flak cannons are very heavy, so it takes a lot of rotors to get this thing off the ground. It can sort of fly with the big rotor and two other smaller ones, or all four small ones, so a couple of the small rotors are mostly there for redundancy and extra maneuverability.
