I learned to fly using the free flight simulator FMS. I got to where I could fly around inverted, and consistanly land on the runway. Once I finally got my plane in the air (LT-40) not once did the instructor have to take over the controls in the normal flying process. The instructor was still a huge help in performing the the first 4 or 5 landings. They were all deadsticks due to the clunk being stuck in the front of the tank. I think I soloed on my third or fourth day at the field, thanks to FMS.
