To re-iterate a few of the above suggestions:

Don't buy anything until you visit the club and hopefully line up an instructor and see what he uses. As Grey Beard said, some instructors actually supply the trainer, at least for the first few sessions. Visit the club, see what people are using and what plane(s) they recommend before you buy. If you run out and buy a plane that happens to use a different transmitter protocol than your instructor has access to a buddy box for, you're pretty much out of luck without investing additional money.

Instructors are volunteers and quite frankly I'm not sure they need to be very good teachers or your best buddy either. The biggest thing early on is to get stick time (and a lot of it) without the risk of crashing every 15 seconds. The minimum an instructor needs to do is take off and land for you, and to be able to save the plane from crashing while you learn the basic control movements and develop some muscle memory. Anything else is gravy. Most instructors will be far better and teach you safety, setting up the plane, trimming, basic aerodynamics and aerobatics (eventually), etc but my point is that you don't need the RC equivalent of the Teacher of The Year at first, nor should you expect it.

And, you have to invest the time to learn. Unless you're naturally gifted (or young), you need to be getting several flights a week in until things start clicking. Once a month is a waste of your and your instructors time.
