Awesome laser tank is awesome!! Gotta fix it, though. A prismatic laser/microwave/etc. beam emitter is a natural choice of weapon for a hover tank. Hover tanks can't use cannons with a lot of recoil, since they aren't in contact with the ground and will be knocked back extremely violently with each shot in absence of ground friction. Rocket launchers, missiles, or even a recoilless gun could work, but prismatic beam emitters are far more impressive. Your work is pretty good, keep at it!!
