RE: 9C for beginner
Unfortunately I can't help you with the wind challenged students. I don't have any of those. I'm not bragging about my skills as an instructor, it's just when you learn to fly in Oklahoma you learn to fly in the wind. our normal days are usually too windy for a lot of other pilots. A normal flying day will have the wind 10-20 mph, and we don't consider it being too windy until it gets 25-30 mph. So by defualt they learn to fly in the wind.
