Gee, when I was being taught to fly, we didn't have but one stick, or should I say one button. Once for left, then once for right, and if you wanted the same direction again, we would double click the button. Yet this was in 1962. All kidding aside, the ruder and throttle are very important. Learning to use the rudder in order to make corrections during take off and landings, as well as correcting for cross winds, will come after the basics of R/C flying have been mastered. As a full scale piolot, you already know how to use the rudder. There is no substitute for stick time. Get all the stick time you can, no matter who the instructor is. The main thing is to get comfortable in the air. I have had the joy of teaching many kids and adults how to fly R/C, and until they are ready to depend on the rudder, I tell them that the rudder is only used for corrections on the Ground. Good Luck.
