I know that one reason that I don't respond is that some of the questions I'll see over & over, and that "somebody else" will surely answer it. I read a post just today about instructors & the help that they give, and I believe that one person said that only three out of twenty people stay with the hobby because the others are probably just curious. I'm sure we all run across some curiousity seekers who want to know "how much" and "how difficult" things are in the RC airplane world, and if it's too much or if they feel it's too difficult, they move on. I'd like to say " Thank You " to RC Universe and to the moderators for all the time they put in for this great hobby of ours. I know it's helped me quite a bit.
