I have bought G2 a two months ago and 10 or 20 hours on it has REALLY improved my hovering, rolling circles and harrier rolls. The stock plane don't 3D, you have to download modified planes. My favorite is the 330 competition on the Realflight dowload site. You can modify any plane to fly 3D too well to be realistic.

I have watched the Aerofly videos and it looks almost TOO easy. The I don't see the planes dropping a wing etc.

I have not flown Aerofly but from all the comments it seems to be the best choice.

I wish they'd put out a free 30day trial, I'd like to compare it to G2 before I plunk down another $150.
