Realflight G3 and Aerofly Pro Deluxe are very good simulators. I use them both and learnt to solo on my own with no crashes ( well maybe some hard lardings ) on parkflyers. The planes in AFPD are very precise and flies far too easily as if they riding on rails in the sky, which might lull an inexperienced pilot into a false sense of security but otherwise its great fun. G3 is a little bit more unforgiving and the planes need more stick corrections as they fly especially if you dial in some wind. One of my fun things to do is pick the most twitchy and snappy plane, use the editor to transplant in a monster engine and now you have a screaming fast hotrod plane that will give you a real workout on the sticks.
