This is the newest, latest edition, G4. It's the best and most popular RC Simulator software on the market http://www.realflight.com/ It comes with the USB Futaba controller. If you want to learn how to fly RC Helis from beginner to expert, this is IT!! It also has lots of RC planes as well along with quite a few beginner and more advanced flying fields. Expansion packs are available also but there is PLENTY of aircraft in this package to keep you busy for a long time I bought it for the Helicpoter sim and it REALLY works great. I'm just spending more time with the real thing and no longer fly simulator. Everything is in as new, perfect condition. Costs $200 new, I'd like $125 for it shipped within the USA.
