Get an instructor. Flight sims aren't very realistic but they are helpful and you'll learn faster if you use one. But I wouldn't put my money on being able to go out and fly an R/C plane just because I mastered a flight sim.
Keep in mind that if your planes hits somebody or damages someone's property you'll be on the wrong end of a lawsuit.
