My advice would be (for what it's worth) to have a very calm and friendly conversation the next time you go to the field before you guys put the plane in the air. Explain to him that he has you flying so fast that you are behind the plane and it bothers you. Give him a chance to understand your feelings and adjust to them. If he is unwilling to adjust to your needs then start looking for another instructor. Don't let him run you out of a fine hobby. And HE needs to adjust to YOUR NEEDS, not the other way around.
