I have just got a couple of graupner high start pulleys for our club as hand tows can be hard work when the breeze is very gentle
does anyone know how much longer the line should be when using a turn around pulley

do I need to go as for 200m or with the ground distance be a lot less that the height ?[attachimg=1]

I don't really understand the question tbh. What are you using now?  High starts with bungee rubber?

And you want to use hand tows instead? With mono line?

The other way round?

Sorry I got confused by the words high start.

As far as I know in F3j when they use two man tows they don't double the line back to the model like you do with a winch. I don't know how far beyond the turnaround they go though.

Ask an f3j pilot or something (barcs).


As far as I recall there is no increase in line length. The idea is to reduce the effort of the towing person. I know when we were towing up gliders in Kent Interclub in the 90's the tow man placed the additional pulley over the line, plonked himself on the ground and held on for dear life as the tow man went towards the pilot. In general they were towing up balsa/plywood gliders and because of the increased speed were kited up quite quickly so did not lose too much of the line length.
Hope this helps.

When We used the two man tow at Timperley club, the line length was double that of a one man tow, as a result the two runners were up by the launch point, as this made communication between pilot and runners easier and possibly safer, with not having two guys down bottom end of the field with an out of control model hurtling towards them!
Please ensure the stake it well and truly anchored in the ground!!
