I have only seen one pilot and was told by a friend of another that were able to pretty much be able to fly a plane after just using Real Flight. My instructor loaned me real flight G-nothing and when I was still teaching I loaned my students RF #2 but I picked the plane and had them doing exercises on it after a day of instructions at the field. I like a combination of both flight training and the sim. I have also found age makes a big difference. A 13 yer old will learn to fly a bunch faster then a 65 year old. Kids have been around joy sticks most of there lives. I had a 12 year old and a 60 year old learning to fly at the same time. The kid could solo in one day, the 60 year old took a couple months but a lot of that is fear. The 60 year old understood the price of the gear, the kid didn't care. Funny thing, when he had to buy his own gear he was a lot more careful and started to show nerves.
