This flight simulator has been created by pilots to accurately model very light aircraft and hot air balloons.

The program is designed to simulate the flow of air both around the aircraft and over the ground, and so accurately models the effect of warm air flows for gliders.

The graphics are very good for a game of this cost and size. There are plenty of add-ons available from the Micro Flight website once you have purchased the full verson.

The demo version is limited to the supplied aircraft and maps, and only plays for a limited time.
