I think I have to agree, I do already have Simple Traffic and am uninstalling the FSTraffic as we speak and asking for a refund. I sent them a bunch of questions and issues but we will see what the response is after the weekend.
Note that the best place for feedback and questions about the new layout is the New Forum Software section.

Please forgive me and disregard my last entry. I found how to view the entire aircraft.
I just need to be patient and explore the site more thoroughly.
I'm actually liking this site more and more each time I visit.
Thanks for all your hard work.
Use the FS9 forum here.
I will admit this, if you are coming to FS9 now, it'll be more difficult to find all the add-ons. Some are simply gone or download links are dead. Members here may be able to help out with certain add-ons you cannot find. On the positive side, there are quite a few payware add-ons that have been released for free still available. I do also run a lot of payware in mine that is still payware.
Have a play with FS9 and do some digging, ask questions in the FS9 forum.
If you find you are not enjoying yourself you can always switch back to FSX.
Both FS9/FSX can happily exist on one drive. Install as you have suggested, C/FS9.
Most importantly, have fun!
