PILOTO:
Welcome to your new addiction! If you're like most folks, the first few weeks online are going to be very fun, but also very challenging. You'll get shot down a LOT, and your mental health will be helped if you accept those virtual defeats for the learning experience that each offers. Film all of your encounters, and watch them over and over again, using the "Film Viewer".
If you haven't already advanced beyond the absolute basics, you might enjoy the video clips that I put here:
http://www.TechVideoReview.com/FlightSimMovies Look in the "Aces High" section
I created those videos for a group of Boy Scouts that wanted to use Aces High to study for their "Aviation" merit badge. They start out VERY basic, on the assumption that viewers have absolutely no background in flight simulation and that they know very little about computers. They advance to the secrets of gunnery and squeezing the most out of your computer setup for each airplane. I hope you find them useful.
In addition, the advice given in prior posts is excellent; most people find it helpful to fly offline for a few days before they face the online masters.
I hope this helps!
