Hi,
in the 70's i made a train of Georges kites, 7 in total, 6 with a span of 4m and the manlifter had a span of 7m.
one send one of the 6 as a pilot kite, at about 150m you have the first stop for the nr. 2 to anchor, every 40m a stop to anchor the other 4.
the pull is enormous. the man lifter is send up the line last it had a trapeze chair and bridle control, to pull up or slide down.
It was very tricky, we needed always 4 to 5 guys for the set-up, and only managed a couple of successful flights/manlifts. 80kg lift was no problem.
This was also done with Cody's (more successfully)
