I went to the starboard website and saw a message that with the wing 800 changing the angle of the stabilizer you will take off with a wind of 5 knots. I have tried it with wing Horue XLW and soared from 8 nodes(as promised by the manufacturer). With an 800 starboard wing, you can't fly at 5 knots. this is stupid.

Note: the 115 Plus fuselage is supplied with six angle spacers ranging from -2 degrees to +1 degree. The recommended Tail Wing Angle Spacer for the RacePlus is -1.5 degrees or -2 degrees:
-2? for wind speeds of 10+ knots (recommended default angle)-1.5? for wind speeds of 8-9 knots -1? for wind speeds of 7 knots-0.5? for wind speeds of 7 knots -0? for wind speeds of 6 knots +1? for wind speeds of 5 knots

Hi antonmik,

did you try to foil with that setup? No? Then why do you know that it is impossible. It's a race set-up, used with high-efficient big foil-sails. Now take that, put a light rider with good pumping-skills on the board and of you go. They don't claim: Flays in 5 knots with a 100kg rider and 5.8m sail without pumping. Anyway, what is your point?

Earlier in my foil career, I owned the Starboard Alu GT with the 800 wing. One day in light air that I entered a lull where the water was almost glassy. I was able to turn downwind and catch a puff of wind that was maybe 9 knots (ripples, not even a white cap) and keep on going. That was the coolest thing - literally chasing the wind. 70kg on a 7.7 for stats. So, yeah, for a skilled lightweight rider with a 9.0 or bigger foil sail (e.g RS:X/PWA types), I don't doubt it at all.

If you want to see how good the really good guys are in light air, a frequent forum poster:

He's on a 900cm wing (Loke L) but he also weighs, iirc, around 80-85 kg.

I think you have to find the best angle shim by trial and error. Figure out what works, and use that. The next foiler will probably use a different one. Don't overthink this. Just try it.

The LP FRS foil also comes with a set of stab cradles that offer a range of down angles. By trial and error, I figured out which one I like, and use that all the time. My other LP-foiling friends use a different one, which works for them.

Nice thing about this sport. Trial and error is a lot of fun.
