That is aeroflypro deluxe. You can get it at www.aeroflypro.com . Its a really great sim program.

1 thing I wanted to mention is that I did those snaps on 3D rates with HUGE throws for demonstrative purposes, that is so you could clearly see what the surfaces are doing in the video. In reality you should not use near that much elevator and aileron throw. The rudder you might use a pretty good bit to really get the plane to snap. The rudder and elevator are really the key, too much and you get too deep and the snap is hard to control, too little and the plane does not stall enough to autorotate.

That being said, on that plane, since the surfaces are so small you are going to need all of the elevator and rudder throw you can get out of it to get it to snap. The more tailheavy it is the easier it will snap, but the worse it will fly.
