This was another of those XPlane10 planes without cockpit (they had the 2D old one), that I had to make for XPlane. Still it is in XPlane 11, and it was worked by me in PBR matterials, but I suppose it is still inside, because is good for using it as AI plane, and in refuel missions. 
As said, it was always a shame not build the 3Dcockpits of these guys, but I totally understand that if they were not going to be deep in systems, then the ammount of time and work spent in them where going to be totally wasted.
