Isaac. Welcome to the world of SB4. You won't see much in the way of livery for it, plus a lot of Paper airplanes. Ya gotta ignore it. I have played with the tutorials and loaded liveries, but since the maker of SB4 is no longer around it is what it is. I have said this before on the several forums we have about this same thing, I run SB4 as FSINN KILLS MY FRAMERATES so bad I cannot "fly" with it. SB4 has the decent frame rates I can use.
If you want to look at the others on line you need FSINN. I look at it this way, when I am on line with VATSIM I am usually to busy to look at the others. I only see them at the airports.
Particularly look at the instructions for setting up the settings on all your planes - not just these FSINN models but ALL your planes.
Whether you get a hit on one of your models will depend on what is being sent by the other person through their SB or FSINN. You don't have a lot of control there except through some default mappings (for non matches, I think) you can set in FSINN.
Wisdom begins when you finally realize someone else is in charge of the universe.
