I had another play with the Flexiwing kite today. I have hooked it up to a Penn Squall 40 Lever drag with approx. 6-700 metres of 60 lb braid.
I went out to have another go at tacking the kite, by attaching some drag to one wingtip at a time in the form of a part of a plastic bag. Without going to extremes, I was getting 45 degrees either side of downwind, without using weights or the Skyhook.
The next thing to try will be some weight on the wingtip along with some more drag, or maybe playing with the bridling on the drogue.
The wind today was around the 15 knot mark, and the the kite is definitely capable of taking much more.
