The most common way of teaching people to fly is elevator/ alerion, but most simple trainers use rudder / elevator control due to the diheadral in the wing. Some models fly better if you couple rudder and alerions together by adding a little rudder with alerion input, and example would be a piper cub, generally any plane that is " short coupled" or the nose is rather stubby benifits from using a coupling mix of rudder and alerion. But seeing or reading that your flying a alerion equiped model, just stick to alerion and elevator flying, but on landings and take off, switch to rudder/ elevator control. The reason being that most people tend to forget about the rudder after having thier hands at alerions, but the alerions aren't going to help you when the wind is not blowing directly up the runway, this is where rudder is most effective for you, instead of banking the plane, you can yaw it into alignment for a landing. I don't know how many people I've seen crash because they blame the wind coming across the runway causing them to catch a wingtip on the ground, it could have been avoided in the first place if they used the rudder more and didn't depend on alerions for directional control all the time. So plug away at it and you'll be ready for the real thing, just remember, the plane can be rebuilt in 3 seconds in a simulator, but the real thing has no reset button and it makes you know that the first time the instructor says " It's all yours"
