Wow! Everything is invented nowadays!

Yes, I think the Voyager Light-Speed is the only one, at least I know of :thumb:

Most or all others are quite low AR, compared - and feels like that too in every way, both good and bad :wink:

Thanks Dave, so FRX is only kitefoil or is it also windfoil ?

Re: Delta Hydrofoil's George Hradil talks foil design and the future of the sport

What is FRX ?

If you google Neil Pryde and FRX very close to nothing pops up...

Can imagine it could be a foil one design class, but kitefoil or windfoil (if correct that is) ?

Re: Rear Stabilizer Wing

A symmetrical rear wing profile will work just dandy :thumb: Especially when a bit experienced, as then you dont want it to pull down much anymore, as this will give the kanguroo effect instead of a balanced foil that dont go up nor down at changing speed. I have got several symmetrical rear wings o...

Re: Top speed of a Moses 633 SUP wing combo (the Onda)

Peter, do you tend to associate larger/slower wings with beginner riders and pushing the race wings as a pinnacle of foil development for “experienced” riders? Because nether Gunnar Biniasch nor Greg Drexler are beginners and they can ride either but both like large wings for freeride. Ability to g...

Re: Top speed of a Moses 633 SUP wing combo (the Onda)

I thought it was variable amount of lift at variable AoA. Then at certain AoA lift decreases, a stall. Some wing designs, thus curve is falling drastically and deep, like cliff. Other wings the curve is more like a hill. The cliff curve is difficult to recover from, the hill is easier. Very true. E...

Re: Going from Short Mast to Long mast Advice

But as said before, pretty sure now, the misconceptions to one or the other side comes between those who can accept a slight touch(down), and those who can not, thus VERY different likings appear :naughty: [/i] I wonder how long will it take me to get good enough to hardly never touch down, when I ...

Re: Top speed of a Moses 633 SUP wing combo (the Onda)

slowboat is spot on, with a kite the stall speed can not be "claimed" - makes no sense at all. If one should use a scientific claim that could be used, it should be the polar max lift coefficient for the whole setup (actual wing not profile so also induced lift loss included) which is a unitless val...

Re: Going from Short Mast to Long mast Advice

I hardly never lean back (that is for racing only), I lean forward in tight turns like surfers in lay down bottom turns, and this is the "holy grail" for me and what it is all about very often. But of course, when turning back on the wave (like a cutback) I lean back - and again - length is needed u...
