There's also crrcsim, which is free and open source and has really nice physics. It works well with my Taranis X-Lite and a USB cable. It's only for LOS, but it's the best LOS sim I've ever played, and the wind in it is *really* nice.

I've just installed AccuRC 2 because of the fixed-wing stuff in it, but there's no FPV in fixed wing yet, which is a bummer. They're working on AccuRC 3 right now, which will have much better fixed-wing stuff in it. Fortunately, it's a free upgrade if you've bought AccuRC 2. Alpha testing is supposed to start soon.
