RE: Quality Free Simulators?
The latest Real Flight is awesome, I think is 5.7
You can change the wind apeed and direction, the sun's position and several different fields.
It has a lot of airplanes and helis.
About the $180, it is worth it. It installs in 5 minutes and runs perfectly 100% of the time.
Figure you can fly day or night, rain or shine, snow or sleek.
If you crash it, hit the red buttom and presto a new plane, even full of gas and turn on.
It also have a section of videos of pros teaching you advanced maneuvers.
I always practice a new maneuver at the computer until I master it then I try it at the field.
