This thing can go on land and water. It has 2 machine gun turrets and one anti aircraft turret (with the cockpit on it.) To use the turrets you must first activate the pistons. For the first gun turret; activate 2 and extend the turret first, then click 1 to activate the turret. For the missle turret; activate 4 and extend the piston then click 3 to engage the turret. For the second gun turret, click 6 to extend the piston and 5 to activate the turret. To activate the rocket booster (allows you to travel over water and help you on uphill climbs) click 7. All of the turrets use trim and VTOL for motion. Have fun with this thing and feel free to edit and re-upload.
