I like this line of thought @PierreB
Makes me want to go and check back over my soft kite data.
But Iām sure the rigid blades made a lot more power because of their speeds.
Also
I had a single skin kite (flysurfer Peak5) flying waaay past straight up over my head today
Just come back in from leaping/running/kiting up and along the ridge of hills ā¦ The wind blowing onto the hill gave huge lift. Was getting flung around a fair bit. Fun
