Re: RES: [ksurf] Fully sheet out kites

Yes and No

The front lines were on sliders like this but the sliders were much longer.
About 3 feet. They ran from the front attach point to the leading edge near the
2nd struts. If the center strut is no 1 then the struts on either
side of center are number 2. So in Sheet out position it was almost like
holding the leading edge. Near full depower.

This idea looks pretty cool though. If they are right - that it lessends drag
during turning and sheeting in - then it might be worth doing. I'll have to try
it on an old kite.
