I would have to say that FMS definitely helped me learn to fly. I had a good friend who passed away around six years ago, he was an R/C aircraft nut, I spent allot of time watching him build and fly his models, but at the time due to finance I was unable to get involved.
Four years ago I was looking for a new hobby, it was a toss up between karting and R/C aircraft.
I decided that I wanted to learn to build the models as well as fly them so I brought a trainer model and began building it.
In the mean time a friend that owned a bike and model shop asked me to have a look at a flight sim and usb transmitter that a guy had dropped in trying to sell.
I took it home and had a play, it turned out to be FMS, I decided to purchase it myself, on the CD was a link to this place and with the help of ggunners, I started to build my own models for FMS.
I must have had at least a thousand flights on FMS before I got my trainer finished. I joined one of the local clubs and took my model out to learn how to fly the real thing.
On my first flight my instructor took of and handed me the TX, I flew around for a while, I remember the instructor commenting on not having to do much. I handed him the TX and he landed.
The second flight was much the same, except after a couple of circuits the engine died, I was way out over two paddocks and fences about 300 - 350 metres away from the strip and quite low. I began a glide back to the strip, my instructor had a bit of a panicked look on his face and asked if I was going to give him the transmitter back to which I answered, no I'm fine. I flew the model back to the strip and made a nice landing on the strip finishing up a few metres away from us, claps and cheers from all onlookers.
I went solo on my 5th flight.
If it had not been for FMS this would have never happened, I still use FMS to learn new things and often practise knife edge, slow rolls etc.
