You MUST learn rudder use if you're to survive in this hobby (unless your're rich), because right from the beginning you must steer that airplane on the take off run before you're up in the air, and if using a tail dragger, you must compensate engine torque with opposite rudder, then you must use it when flying, and almost always while using ailerons (and not necessarily to the same direction), and then when landing, you must use rudder to align you plane with the runway, there is almost always that crosswind to compensate for, then you must taxi back to the pit area, and guess what is used?
For a beginner I recommend going to the field when nobody is there, but you and your flying buddy, and just taxi your airplane around, as if it were a car, you don't have to have the wings on, but do cover the fuselage opening so no exhaust from the engine can mess up its inside, and make sure you can master turning that airplane when it is coming towards you, it must be an automatic thing, if you do this, you'll be a great flyer for the rest of your life, if you don't, then you better learn to become very rich ( $$$$), as you'll be destroying most of your airplanes, 26 years experience here! Do it! Do it!
