I have yet to I back my FC 40, the reason being, I am totally in the dark as far as programming ans setting up electronic devices. I must admit, some of the posting's I have read here, make me wonder, if I would not be better off with a regular remote controlled helicopter. Then the second question is, if I achieve a modicum of proficiency, will I soon regret not stepping up a grade or two. The bottom line, I am totally in a bind, and notice a lot of members here have made ingenious workarounds, which are totally out of my realm. At least back in my photography days, there were, seemingly, unlimited sources of books available. Thank you!
