All really good pilots use rudder. All crappy pilots ignore it. If you want to be a good pilot, learn to use the rudder for takeoff, landing, coordinated turns, controlling direction, aerobatics, and a whole lot of other things you haven't done yet. If your instructor isn't using or training you with the rudder, look around for another instructor until you find one who can show you what it's for and how to use it. It's there for a reason! good luck!
