I am trying to find a Mustang P-51. I downloaded one from the "http://rcp.cside.tv/Rc_hp2/fms/Metasequoia_e.htm" site.
I am not sure what I have actually downloaded, as I am unable to open the plane in FMS. Have I actually downloaded a plane or just the plans of a plane? Do I need to create the model myself or am I able to find a plane that I can fly in FMS?
I would really appreciate any help.
