to drop the Anti-tank turret, use activation group 6, wait for the box to get reasonably far away from the plane, then press activation group 5. you can either land the plane, or just let it crash. wait until you hit the land or water, use the Trim bar to open the box, when landing on land make sure landing gear is out until you open the box. When you want to use the turret, deactivate group 8, and you can use activation group 7 for rotation, and activation groups 5 and 6 for elevation. Make sure activation group 7 is off when using elevation. both turret rotation and elevation are controlled with trim. them rounds are numbered 1-4 activation groups. use the Vtol to control the cylinder, you will figure it out when you use it in 3rd person.
