This is my favorite place on RCU. The beginners. This is the place that makes these forums worth while. Teaching or learning. Out at our field or some field in ANY PLACE USA. I don't seem to find much difference. To me the model aviation field has always been a place to go share my love for aviation. A place to relax and put the rat race out of my mind. Sharing the hobby/sport has been a labor of love for me. This is how we are currently doing things. We have two intro-pilots. They do just that, introduce folks to the hobby. Then there is my flying buddy and I. We will help any AMA member that may need or want our help. There is two of us for several reasons. Ronnie can get along with some folks and not others. I can get along with some he just can't adjust to. It is strange how that works. The younger kids really like Ronnie. The older kids take to me. One of the things we try to keep in mind is it takes all kinds. We both try our best with the older guys or those that have a problem learning. The OP ask how to handle the guys with flawed planes? We have our system and I promise it has flaws, but we do the very best we can.
I would like to say for the record. All you people that do your best to give the best advice you can. THANKS!
