I downloaded Keyesystem's K-2 AA gun and added the P-51 Mustang installed in the game. This created a fun minigame. You have four shots (detachers 1-4) to blow up the Mustang. Press six to throttle up the Mustang and take to the skies for a triple challenge- remote-control the plane, while trying to control the gun, while trying to shoot down the plane. I do not own either of these marvelous machines, I have simply combined them in an ingenious matter for a great game. Use VTOL to move the gun up and down and use roll to turn the gun. I believe they control the plane in the usual fashion, but I am not sure. Use detacher 6 to detach the plane if you want to try the extra challenge. Good luck!
