Welcome aboard - you are gonna have so much fun it will be some of your best memories of life.
Can't say enough how important it is to choose a reference point well out in front of the machine.
After that it is like riding a bike. A noisy, vibrating, hot, uncontrolable bike but a bike all the same.
I agree that you have to be gentle on the cyclic - if you can see it move it is probably too much. Pressure not movement.
Easy to say - hard to do- "Use the collective to adjust your altitude. Use the cyclic to control your position over the ground. Use the pedals as necessary to control aircraft heading." I can still hear my instructor "Outo Al" in my headphones. Of course he would then place one finger on top of the cyclic, one on the end of the collective and do a flawless hover pattern saying: "It is not, as I am demonstrating, half as difficult as you are making it!" I still can see the dings in my old helmet where he used to hit me with his clipboard - all in fun of course! Great guy! 30 years later we are still in contact.
If you find you are trying to squeeze toothpaste out of the cyclic try placing the stub of a pencil between your index and little fingers with the other 2 on top. When you tense up the pencil will hurt your fingers and you will relax your grip. Unless you are a glutton for punishment! - I have seen this work a lot. In the old non-PC daze a cigarette worked even better - as long as it was the student's cig and not yours and he cleaned up all the tabacco from the floor after the flight.
