nellycopter, I don't suppose that eddietcapt was your instructor by any chance? Or are you one and the same?
1000's of hours don't neccesarily mean a better instructor.
Find an instructor with the knowledge, skill and ability to teach well. Also, believe it or not, dynamic take-offs every time and low level arse-ing about aren't just what helicopers are about.
I personally feel that if you wish to be a professional helicopter instructor, then you should hold at the very least, a CPL level qualification.
