If you really have no access to an instructor then get all the practice you can on the SIM and do not try to fly until you can takeoff, land, fly towards you on the SIM and do it all without thinking about it and crashing.

Sims cannot replace the real thing but they do help especially with orientation.

NOw to what you are going to here allot of. Try to get some instructor training if at all possible, there is more to flying than just put the plane in the air. You have tuning the engine, checking for loose or broken pieces on the plane, and all the little things to know about on how and whya plane flies. You can read and fly sims all day long but the one on one instruction from a instrucor cannot be beat

Whatever way you chose, please always remember to think safety first, both the people and surroundings around you and yourself. R/C planes are allot of fun but can be extremely dangerous, even the smaller electric park fliers can do some serious damage to fingers, toes, eyes, etc...

I am not trying to turn you off from flying, but I am just trying to get you to think about safety as your first priority

Learning to fly on your own can and has been done succesfully
