1. Host a server. (Single player is k)
2. Spawn a Warthog. (Or any other vehicle with a good turret that you like)
3. Type /getid on the turret.
4. When you see the random numbers, memorize/write them down. Just make sure you can know them.
5. Spawn a stunt plane or biplane.
6. Type /getid on the plane.
7. Rememorize this ID, too.
8. Type 2ndID.mountObject("1stID,1-4");
I think this should work. I've always tried stuff like this, but my console hates me. :c
