Top: classic turret mounted, manually operated M134 similar to one found on the black hawk, middle: front or side mounted minigun similar to the A-10 front mounted or C-130 side mounted and sticking out perpendicular to aircraft, bottom: underwing similar to AH-64D gunship.Please note that in order to achieve barrel rotation, two rotators are used. The rear one is always rotating counterclockwise and front one clockwise. They canel each other out until FireGuns is pressed, which means front rotator spins opposite direction. Due to how they work, rear one must be mapped to an activation group, otherwise the barrels will spin constantly. If that activation group is pressed they spin as well. If your craft has all activation groups already used, you may experience issues like uncontrolled barrel spin.
