The problem with a simulator is, who's there to let you know when you've done something wrong?
Something as simple and basic as flying behind the flight line. No simulator will prevent this but most if not all clubs have rules against it. Then there's the guys who seem to think they're still flying control line as they turn around and around as they fly their plane around and around in a circle. No simulator will say, "Hey! You're screwing up! Do it this way!"
It's far too easy to develop bad habits when you rely on a simulator unsupervised (no instructor) to learn to fly. Then at some point you'll have to un-learn those same habits. And that's not so easy. So get with an instructor, learn to fly the old fashioned way. Then use a simulator to practice the right way you've been taught. Basically keep your thumbs limber.
Full size aviation uses simulators the same way. As aids to learning but not as the sole source nor initial source of instruction. New pilots get one on one instruction with an instructor sitting next to them before they ever touch a simulator.
