I tried FMS when I first started three years back. I couldn't fly a full minute without a simulated crash. I couldn't find the runway. Really disapointing. Then I got my trainer, and an instructor and although I was really slow, something about an old dog and new tricks I guess, I finally soloed. that was a couple years back now. I've crashed a number of planes now, none of them jumped up and got back on the runway for another take off

.
Just yesterday, I stumbled across the FMS cable, so I fired it up again. I can't fly a full minute without a simulated crash. I can't find the runway. Really disapointing. HEy, I said that already. Nothing changed on the PC. I'm better on the real field.
Learn to fly the real model. Cross winds, distractions, wind direction changes, gust, sun, clouds, Birds. all the things that make up a flight don't happen on a simulator. Doing predictable things is one thing, but handeling unpredictable ones is what makes you a pilot. That and the knowledge that your plane isn't going to suddenly show up on the runway just after a crash, but is going to take several hours of work to get it there.
