Here I am limited to 60m unless I notify the aviation
authority (which I don't want to do), so I thought about
using 2 or even 3 kites in a row each at 60m, spaced maybe
100m or so.

Trying this cheap and simple single line parafoil

 https://www.amazon.co.uk/gp/product/B00LZWGKMY

It says "stable and accurate flight".  Well my experience is
different!   I think the winds are a bit too strong and it
quickly becomes unstable.   Next experiment will add two tails.

I've got to give this cheap kite a good try, because the next
size up is £50.   It seems to have plenty of pull, enough to
lift a thin wire, just need to make it stable...

If I can get something to stay up for more than a few minutes,
I might try some LF transmission.  That could be entertaining.
