This is a Work in Progress
As another neat Shug video, it's cool.
As an educational video to show to prospective field landlords, I think it's both incomplete and too long. I see about a minute of footage that you could work in, and not, in my humble opinion, anything for an opening shot.
If your goal is really to show people "this is what it means to
you to host our club", I think you need to start with some sort of a summary shot -- I want to give you a number of suggestions, but I keep coming back to showing an overhead shot of someone flying. Getting a quadcopter pilot interested in the overhead shot is an idea, but I almost think that an animation would be better -- a shot of a real plane would give you a hard to see, fast moving dot, where with an animation you could show a larger than real plane, a heavy black line for the "lines", etc. Someone on Stunthanger has an animated GIF for their avatar that would be nearly perfect, except it doesn't show a full lap.
I'd follow that with the scene of you hooking up the lines and then cut to your handle, but with a voice-over (and maybe a caption) explaining that "control line" means that the airplane is always tethered. Then maybe go from there about stunt, sport, etc. Like a newspaper article, I think you want to put a summary of of the whole video into the first 15 seconds ("Control line is fun, safe, educational, and it'll make the plants grow!"), then go on to present things most-important first, so that if the viewer clicks off in the middle you've still managed to transmit something useful.
I don't want to tear you down or discourage you -- just to encourage you to put yourself into the head of someone who's never seen CL and probably has RC-based misconceptions about it.
