Don't worry mate - Don't let turbulence or anything trouble you! Just relax.
My instructor was excellent on my first lesson, I did everything except land, although I was a little tense at first.
After a touch and go, we established level flight and he made me sit back and leave the controls alone. Neither of us touched the controls for about 30 seconds, after which I applied some trim to maintain level flight.
This showed me how balanced the aircraft is, and that all is required is small, smooth adjustments on the yoke.
Try it!
I recently had my second lesson, and already I have a nice relaxed grip on the controls, and I almost landed!
Good Luck,
Mike
