I would imagine that having the winch at the glider end and running the
wire/rope/whatever through a pulley would create a lot of drag and wear on the
part of the line that runs the full length of the strip to the pulley. Given
your average Aussie dirt strip the wear rate might be unacceptable. Normally
the wire is only on the ground for the ground run and initial climb.

One reason I can think of is if the winch is at the glider end of the runway
it is an obstacle to landing aircraft.

AH, O.K I thought it was all at one end - so what's stopping you from using
the pulley system at the end with the winch at the glider?

That is of course the retrieve winch , not the launch winch.

Subject: [Aus-soaring] Auto-tow launch info
I had quite a few inquiries about the auto-tow system
(it's sold) so I thought I'd put the info for the
yahoo pulley launching group here. There is some good
info on pulley launching for anyone considering this.
http://groups.yahoo.com/group/pulleylaunch/
If you'd like to talk to someone local who's using it
Boonah club in Qld have built and used an auto-tow.
Cheers,
Greg.
