RE: E SKY Simulator
Do this: Purchase the Esky controller(make sure you get the 2007 version it is USB 2.0) (I got mine on ebay $25 shipped) then purchase the Clearview [link=http://rcflightsim.com/]FlightSim[/link] . It's only $30.00 the graphics are excellent and the aircraft parameters are adjustable so you make the birds as unstable as you like. FMS blows, it's like commodore 64 all over.
I have used this combo and I'm a new heli pilot since mid january and I'm already doing FFF. A far way from excellent but having fun.
check it out,
