hi rcafmad,
I haven't installed this one yet. Are you installing a driveable vehicle (which is set up in the aircraft folder and the game thinks it is an aircraft taxiing everywhere) or what Airfighter55 calls an AI vehicle (which is a normal vehicle installed in the vehicles folder and does not have all the m3d cockpit files for the gunner, etc)?
If it is a driveable version, then you should have all the usual files which an aircraft has. You should have an xdp file, a cfg file and air file, textures, model and sound files.
If it is a vehicle you just need textures, an m3d, and an xdp file.
The xdp file itself will tell you whether it is a vehicle or an aircraft.
HTH,
