Yosser,
Welcome to SimV. This is a great place to share your interests in aviation and MSFS. Certainly there are a lot of helpful, friendly, and knowledgeable people here. Like yourself, I am a bit new here, too. But, I have discovered a few different things, though, over the past month or so, and I would like to share just a couple of ideas that may help you out.
1) If you are requesting an aircraft for use, there is a specific forum for that and it can be found here:
http://www.simviation.com/cgi-bin/yabb2/YaBB.pl?board=aircwnt2) All of the forums have various guidelines "stickied" to the top of the forum to help you know where and how to start a thread. A well written thread in the right place is the best way to make sure you get the help you need.
Good luck with your aircraft search, and, again, welcome to the SimV forums. I hope you stick around and take the time to read through the forums and get to know people. I think if you do, you will find that SimV can be a great place to learn and to share.
All the best,
~Darrin
EDIT:
See what I mean about knowledgeable and helpful people! Before I could even get this long-winded post off, Pete beat me to the punch and got you going in the right direction. What wonderful people we have here!
