Re: How to turn a hydrofoil - and what is YAW ?

Hi Peter. Thanks for taking these efforts. Clear Explanation. One comment.... I would think the term YAW doesn't come from aviation as it is also used in the maritime environment. Since boats are around a couple of thousand years longer than planes it must originate from our beloved environment. odM...

Re: cant reach full depower

Assuming you are on a TT: When dealing with more power from the kite: 0. Possibly (I dont know your weight) you want to depower/trim the kite a bit when you notice the pull from the kite is on the upper end of what you can handle comfortably. 1. Bend you knees and get your ass and weight closer to t...

Re: US National Park Service seeking public comments on whether or not to allow kitesurfing

Do you have any data about the effects of kitesurfing on birds/ wildlife? This is what is needed. Opinions are not enough. COWI has done a 50 page literature review on the studies investigating the relation between kites and bird disturbance. GKA has this document. I suggest you contact them for it...

Re: Shoulder Replacement

What kind of shoulder replacement are you getting? A reversed total schoulder or a normal total shoulder. Most people won't be able to regain complete range of motion (90-140 degrees instead of 180 degrees). Depowering could be a problem. I'm not clear what motion he loses, but can he switch from a...

Re: G10 wing replacement for fragile carbon

I’m not sure the Gong AOA would help. I owned one. Their stab is asymmetric wing at 0 degrees, best I could measure. While other foils I’ve owned had stabs with symmetric foils at angles up to 3 degrees to make lift. FYI Gong foil is on sale for 799. It’s a good foil. I wish I still had mine. Can y...

Re: Removing struts to convert to single strut Kite.

C type kites are not the best types to convert IMO

This is how a 14m Waroo 2008 behaves with two struts less. See my post above for what I have done.
Yes, the kite flutters when turning or depowering. No, that is not a problem.
