Can't Touch Ground

They should take off & do everything except for the animated gear displaying. Not all 3rd party aircraft are suitable for use as AI wingmen or opponents. The best option is to create AI Only Drones for use in missions. My tute might interest you. http://www.simviation.com/lair/AI%20drones.htm

If they don't perform properly in AI you can tweak the AIR file or use one from a similar default aircraft.

The problem with 3rd party aircraft when starting missions is that you cannot be unit 1 in a formation.  If you start 2nd or 3rd then all the planes will take off from the runway, if you go first then the other planes sit on the runway.

As mentioned earlier they all turn up when you warp to the next waypoint but that is no good if you don't plan to hit X
