At UND, we have a lot of people who do the tailwheel course and then they think that they are the god of taildraggers. Sadly, every year, a UND student will drive out to Crookston MN and take their Champ up and nose it over. A lot of the tailwheel pilots here at UND, dont have very much practical tailwheel experience and arnt really qualified to teach.
I feel that if someone wants to be a tailwheel instructor, they need a minimum of 100 hours in tailwheel airplanes. At that point, you know the inner workings a little better. You can read the winds better and have more feel and finess. Also, your confidence level is up there a little more. Students pick up on your confidence. If you're not confident in the airplane, how can your student become confident? Anyways I'll get off of my soapbox now.
