Sincraft,

You have me beat with the partial electricity and running water. You guys have to get really good to peg the landings on a too short runway. Your club would beat most of my guys in a landing contest.

I have a redneck solution to the 3 channel parachute launch. Use an open cockpit and dump the chutist by flying inverted. Not very elegant,,,, b u t.

More realistically though, some of the sailplane guys use the same channel to serve as a dual purpose control. Release of their tow rope (string) is accomplished by making the release activate at the extreme end of a chosen servo movement.
