I used the g2 sim and when I trained, I was taking off and landing on the first day, and did 7 solo flights on the second day ( of course on the second day, there were no trainers or anyone at the field yet) and did not crash

. I was told it was the fastest training they have ever seen and I contribute it to the sim. The main thing is to put in lots and lots of sim time before trying the real thing and the other suggestion of using some wind will help greatly.
