This simulator is free downloadable from Android market. Is very cool for on the go RC flying on sim. Earlier version used to hang now it is rock solid.

Has two fields. Plain ground and a slope soaring field. Simulation and wind effect on the slope soaring field is realistic for glider slope soaring.

Many models can be downloadable. It even has a helicopter.

Guys with Android multi touch can down load and enjoy. Joy sick is on the touchscreen.

You can snap shot your sim vedio and record your flight video. You can even add additional flaps and other apart from the usual four.

Uploading some of the snap shots

Simulation is very realistic you can see the control surface moving with stick input. The crash simulate is also very realistic like clear view simulator.
