Although there is no substitute for the real thing, I made a dramatic improvement in my flying after using RealFlight. It took the fear of falling out of the sky from me. I was able to try tricks and spins and slam the sticks in the corners to see what would happen, obviously without the risk. I was afraid to try that for real since I didn't know what would happen and I had no idea how much time I'd have to save it.

When I got to the field, I was more confident that if I tried a flat spin, and let off the sticks, I'd have plenty of time to save it (assuming I tried it 3 mistakes high).

It was truly a night and day difference for me. I went from flying in circles with a 3D plane to actually trying things it was made for.
