I can't recommend this highly enough: http://www.condorsoaring.com Be sure to check out the videos on their site to get a feel for the fluidity and realism. This simulator is simply superb. The flight dynamics are the best I've seen yet. Even spins seem realistic. It simulates ridge, thermal and wave lift. Cross country tasks can be set and flown. You can fly online with other pilots. There is a choice of standard class, 15m class and open class ships to fly as well as the fully aerobatic fox. I hope to upload some of my own videos as well as some better screenshots soon. On the minus side, there isn't a demo version you can download and try (are they mad?) and the scenery, nice as it is, is limited to an area in Slovenia. Update: since I've being flying tasks online, the sim has taken on a whole new dimension. It's a great way to learn for more experienced pilots as well as have a bit of fun and competition.
