I haven´t weighted it yet, too big in volume for our kitchen scale...
Quite light for the size with skytex 27g/m² on the skins but not super light due to 40g/m² ribs.
Hehe yes, and it steers rerally direct and turns good (for the size) I wasn´t bold enough to do a loop on the beach in 10 to 15 knots today but tomorrow in the water I´ll try one. So really light wind hydrofoil with start loop should work fine once learning to foil
Probably also fitted more towards small race-ish front wings but will try with the 633 when i can ride.
The billow looks like in the computer so I´m quite happy. Also there is some tension in the leading edge and the wind pressure doesn´t causes dents or bulging in the front part of the billow, so its good. Of course if you had more prototypes one could aim for lower billow values to see where the boundaries are but when you only have one try better to be conservative and run a bit more which seems to have worked.
Yes there´s defenetly more lift coming from the profile, which has more than one reason I think:
-Increased billow on top (more camber)
-More camber in profile (1,7 to 2,03%)
-higher AR so more eficcent wing better L/D
It does fly far towards the wind window but it does not fly way above your head and beyond so you get a stiff neck like on pure race kites.
That´s also due to the lower projected area/higher arc shape so the tips not really help much for the lift being more vertical. But because of this it turns better and that´s more important especially in light winds for me than the last degree of upwind angle.
Stability seems to be good so far. It is higher AR and you see the tip rolling in and going out a little bit 5-10cm from time to time you see on most high AR kites but it did not collapse and there were quite some gusts and holes. I also did the running downwind towards the kite test trying to outrun it and it drifted nicey with me. Of course it was also more like the high end wind today and the picture will change when barely flying in 5 knots or so lets see.
Tomorrow test on the Surfboard and then the wind will also be more east off a high forest so it will be the true stability test tomorrow.
