Hi,
I'm going to try and 3D print something similar to the slingshot glide space skate, not sure what profile to use (I'm aiming for 2.5 degrees positive AoA - then shim to 3.5 if needed) any advice or thoughts? I want super fun, easy to carve, easy to learn new things on, get me through the gusts and lulls.
Space skate is 1,500cm area, I prob won't go that large, my current front wing is 600 sq cm, so maybe around 900 to 1,000 sq cm?

Few notes:
- For kitefoiling at 200lbs the 1000 sq.cm is probably as big as you need to cover both lightwind and regular freeride.
- 20mm profile thickness of 683s as opposed to 25mm of 633 allows to fly faster
- swept back, arrowhead leading edge shape will allow to avoid seaweed collecting on the wing
- higher AR gets you more stable setup - infinity 76 is about same area as H4 space skate but is a better wing

Very interesting. I didn't understand your profile comments, could you link to the profiles you mean, please
I'm struggling with my turns and switching my feet. Turning feels sluggish. And I'm so crap at switching my feet around. Do you think the gull-wing shape promotes a bit of agile-turning?

Basically I was saying the 20mm profile thickness is just enough for universal kitefoil wing with very decent lowend.
I think gull-wing shape doesn’t make much difference, and it’s rather more important wing features like area, profile thickness and AR. Maybe winglets have a bit of effect too.
As of turns - fly the kite, that’s the key.
