Making Flying Lines

Last week I gained a better appreciation for good flying lines.  I'd been flying these airplane kites on some 80lb test spectra sport kite lines, and they flew well in 15-20 mph winds but didn't seem any faster than my wife's parafoil in lighter wind, so I ordered a roll of 20lb test Tuffline XP fishing line and made up a set of 100 foot lines from it.  When I tried the airplane kites on that line, they went a lot faster and the flying area expanded greatly, although there was some line stretch when the plane flew through the area of maximum power directly downwind. 

Why the big improvement?  The speed of a kite depends on its lift to drag ratio, and with these small airplane kites, the lift isn't much compared to even a small parafoil or delta kite, but the line drag can be quite high if you use large diameter lines that are recommended for those kites. 

I recommend white or yellow, 20 lb test for light wind or small kites and 40 lb test for higher wind or bigger kites.

Here's an example of the fishing line:

Here's the knot that ties them to line connectors.  So far, it has worked fine. (click on knots):

Here are some connectors.  I use medium or large ones:
