It doesn't. No helicopters. Graphics aren't as good, sound effects are laughable, the physics engine allows planes with no landing gear to ROG (!!) and support from the manufacturer is... well, minimal.

It's better than FMS, though

The sailplanes and trainer (Sig LT-40) modeled are very realistic. There's a Zagi-400 model included as well - it flies exactly like the real thing. Except for the ROG thing. Hehe.

*And* its only $10 bucks if you have a joystick already. If not you'll need a TX interface - check with simblaster.com.

I bought a copy to loan to people that are interested in learning to fly, but can't always meet me for lessons. Its certainly good enough for that.
