I used to worry about having to walk out and find my tow line in that scenario. We fly at a sod farm and I can't leave the line out if it goes. Turns out I usually don't have to go find it as the glider brings it back hanging off his nose!

Sorry for not completing my earlier post.

Your right about releasing from the tug, but once the tug rolls and dives to the ground 
for the next tow it is usually too late. Even if the tug pilot (which is usually what I'm 
doing) catches the non release the poor sailplane is already getting ready to "crack 
the whip". With larger sailplanes, 6+ meter, it isn't too much of an issue as they 
usually out weigh the tug. It only takes once though, and that's too many times..

What's the problem - doesn't your tow master have a release in his plane? I have one in my tug - and I ain't afraid to use it!

That's all good, but the only thing I would stress is to use a
"good" hi-torque servo on the tow release. You should not skimp on
the release. I've been doing this Aerotow stuff for a while and have
seen



John,

Our tow master insisted on testing all tow release with a 20 pound
pull on a fish scale. If you can't  release with 20 pounds load, he
will not tow you.

I forgot what servo i sued on the Duo, but it passed the test. It is
a high torque one.
