RE: Flew a electric control line
We have found that the electrics are MUCH less intimidating for a newbie or a possible RC convert than a glow engine - even if the glow is only a 1/2A. (By the way, a TD powered Clown on 25 foot lines would screw ME into the ground!).
You can set the electric for a very short flight and the pilot doesn't have time to get too dizzy or to have turbulence get things too out of shape. Plus, you can get a bunch of flights out of a single charge (come to think of it, that is how I learned to fly RC way back when - with an electric powered sailplane that I just launched and landed as many times as the battery would let me before it needed to be charged).
If the trainee is a true Newbie, he (or his parents) doesn't have to learn how to operate a glow engine, which is a whole separate learning curve from just learning to fly.
Congrats on your success -
