And, after having read the whole thread (wow!) I do want to clear up that this is not a "club or outlaw" or "instructor or self taught" thread. This is about dealing with guys who have completely unrealistic ideas about how RC flight works and plan to do something that is 99% likely to result in a destroyed airplane at the very least. Yes, there is the element to the one jerk who thinks that he's entitled to a free place to fly and free instruction (probably free help repairing too) but mostly I'm curious on how, as a representative of the hobby, to handle guys that have the wrong idea about what they should do.

Update: I talked to jerk guy again today. He's already traded off that Cessna for another EDF, a Banana Hobbies F16. He wants to swap it with me for a cheap CP helicopter which he'll destroy in about 5 seconds. I kinda want the F16, so I'm wondering how forward I should be about his plan to self teach heli flying? I did tell him what my experience was and did explain that it's a whole 'nother ballgame compared to his coaxial which he, of course, flies extremely well. I find this guy unlikable enough that I actually want to set him up to fail. Is that un-Christian of me?
