Avoid the frustration/humiliation of teaching yourself, and seek an RC instructor who will recommend a plane, motor and radio combination that they use and are experienced with; chances are that you will love this hobby if you have a successful/satisfying early experience.

Full scale knowledge does help tremendously, but one has to learn the orientation from outside the plane, and your eyes will be the only sensory input. That is a little different.
I came from a full scale background (my whole family flew, and I had about 40 hrs when I started flying RC at age 21).

I also tried to get my brother into RC about 20 years ago: now he is a guy who flew professionally for a south pacific airline, flew aerobatics in a CAP 10, and flew a real P-51 see pics) he owned at that time. I built him a trainer and trimmed it, and having no buddy box, gave him the transmitter with the airplane up high. He did great keeping the model level for the first 2 turns, but after the 3rd turn, with the (typical) reversed controls of the plane facing him, he ended up inverted, and "bailed" by pulling right into the ground!
The whole flight lasted about 1 minute. He had "frozen" instead of giving me the transmitter. He never tried again.

I hope you have a great time in this hobby!
