The RC Groups thread cited by helo36 is a good one, do some searching, there are also others. Taking the required photos and stitching them together is the same for all the sims so good info can be found in threads for AFPD and G3 as well.

There is a very good automatic stitching program called Autostitch, a free demo version is available at www.Autostitch.net. Autostitch does have difficulty rendering featureless blue skies or ambiguously cloudy skies (conditions frequently found at flying fields) and under those conditions (only) it tends to render incomplete panoramas. Nonetheless it is a painless and useful way to explore the stitching process and a good place to start.

I typically have used the Panorama Tools based programs Autopano_SIFT, then Hugin, and finally Enblend. Hugin does the lion's share of the work and Enblend does the masterful blending together of all the images. These are not easy programs to use but they are freeware... A tutorial by R.B. Park is probably the best single source that I know of for getting you started in using these 3 programs (Autopano-SIFT, Hugin, & Enblend) see http://rbpark.ath.cx/photography/pan.../tutorial.html

Park walks you through using each of the programs and also provides links for where each program may be downloaded, plus additional information regarding equipment, etc. In other words it's a pretty good one-stop start up tutorial which any panorama novice should find very helpful.

Here are links to a couple of forums addressing panorama photography more generally... http://www.tawbaware.com/forum2/index.php
