Hermie
I am OLD to flying. I learned to fly in a PA28 in 1975 when it was 12 US dollars an hour to rent the thing with gasoline included.
I've taught in the PA28
I've flown many planes.
Get a new instructor. Get a copy of the book, "Stick and rudder" and read it until your eyes are blurry.
Any time you fly, you should be using a combination of ailerons and rudder to make the plane fly correctly, not just rudder. Why do you think the plane has ailerons?
Mind you, the instructor may think you are using too much ailerons, but then he should say: Look Hermie, you are over controlling. It only takes a little bit to get the plane to do what you want it to.
So please, either clarify things with your instructor or get a new one.
I applaud your choice of the cherokee series of planes to learn to fly in.
