  1. Foil board for next Olympics

    No LEIs? Not very open
  2. Flysurfer Speed 2 19m - mixer issues

    No, the line lengths must be equal, with the bar in and the depower rope tuned to the correct length...which is 40cm. https://flysurfer.com/downloads/download-info/line-plan-speed2-19-0/ Most likely Chook, you did something -- like adjust B before C, or not load up the lines enough when tuning... Another thought Lofty -- if you're using the FDS (5th line) make sure there is ZERO load on it, at all trim settings and however much load the canopy is under. FS bridle lines under the least amount of load shrink the most. I used the FDS on the SA for a short time then went back to FLS because it's basically a PITA to tune the FDS bridle lines to correct lengths relative to the kite's bridle. And makes a spectacular mess when you release and can't relaunch. When I got the S3 21, I was initially disappointed at the lack of power relative to the S2 19, but the Triple Depower made the S3 a far more useful kite and eventually, I got the hang of flying it and accessing the power. EDIT: just checked that link -- I don't remember 3 pulleys a side on the S2, and that brings to mind that the Silver Arrow was actually a Speed 2.5, and IIRC that means the mixer and a few other things was more like a Speed3. FS went through an annoying phase of making small changes and releasing a kite in a size or two with updates, before standardizing across the range. Check your mixer and measure to be sure.
  3. Flysurfer Speed 2 19m - mixer issues

    I had a Silberpfeil (S2 19 Deluxe) for a couple of years before I got my Speed 3 21. Don't remember details (does it have ring lines on the tips? Or was that just the Psycho3?) but I'm sure the basics apply... Your profile is wrong -- you've either tuned out the reflex so there's no shape to the canopy itself to stop it over-flying, or the bridle has shrunk to the same result: bad profile. 1. Make sure your bar is actually tuned, including the right mount of throw on the depower rope. I'd do the tune right up to the bottom of the mixer, so include the pigtails. ... The mixer adjusts the profile of the wing. The assumption with a zero test is that the bridle lines haven't shrunken terribly, or that your SPL (the mixer pulley line) is still within spec. 2. If you haven't replaced the SPL, you should. IMO make your own, use light dyneema <2mm (can't remember the sizes) and make it 10cm longer ie. Speed3 SPL are 100cm and 120cm, so make them 110cm and 130cm. Check the line plan for the Speed2 though. Nice eye splices and a Brummell, and a Zacher knot for the knot end. [There's also a trick that works by adding a second knot the C-line -- there are threads at kiteforum about it, I think foilholio is the author. I think that's about returning throw to Z but never bothered with it... check it out and add the second knot now -- you'll need to add about 5cm to the uncut length.] 3. Mixer text to zero, fly it. Don't forget to line up A and Z, then do C first, not B, because adjusting C adjusts B by half. If it still isn't right, try: 4. Long mixer test. (this is IIRC) Get the line plan, work out the differences between A1 and B1, B1 and C1, C1 and Z1. It's something like 10cm, 20cm, 40cm. Secure the TOP of the mixer, stretch out the bridle lines and compare A1 and B1. Measure and make a note. B1 and C1 -- measure, note. C1 and Z1 -- measure, note. The differences should be the same as the differences in the line plan, within like 10%. If they're not, add a pigtail to C above the pulley -- IIRC. I forget this bit exactly, there's threads on KF again with the details. Fly it. If that doesn't help, then you're going to have to meddle with the mixer. ... In all reality, the S2 was a simple-minded beast that always had a tendency to overfly. And a foil isn't a tube, if you let it shoot to the zenith, it's going to overfly. Maybe you're just over-reacting to it's natural character ... and being too heavy handed on the bar.

    This is on a Facebook group, "Kites for SALE .... USA + Canada" ... might be able to work something out with someone we know in the area.
  5. Naish Foil Board

    Is a whistle the same as a hum though? We're using them interchangeably but I think they're unique. The Alpine is a definite hum by the character of the sound, and the DA would just start humming at a certain speed, like a switch was thrown. My whistle grows in volume with board speed, and probably speed into the wind, I'd have to concentrate. There are mounting holes in the plate, I wonder if they're the source. It's really almost non-existent, very quiet -- unlike the DA or the Alpine. Now I think of it too, the Alpine is a Tuttle mount on a Spots board...
  6. Naish Foil Board

    I was thinking more differences in water pressure at different depths, and how they might travel. My foil's TE are noticably squared, the front thicker than the rear. Tape would be good for free ride but I doubt the racers would countenance it I think the relative stiffness of the fuselage matters too -- wouldn't stiffer transmit more "sound"? "Rumbles" are the turbulence in the water I think, and the trim difference between wing and stab feel similar but more rearward to me... So where is the whistling actually coming from?
  7. Naish Foil Board

    That's very interesting too. You stuck the tape to itself past the trailing edge? Basically just longer and thinner trailing edge, eh. So are you going to thin out your trailing out to a point? Or just slim it down some more?
  8. Naish Foil Board

    That's interesting. I wonder if it matters that the article is talking about vertical surfaces rather than horizontal, and surfaces that are much further apart than kite foils are... 5 or 8 is going to lead to cuts when you kick the foil under water. I think I still have scars from kicking a stab last year. I think my name pops up because I've asked questions and commented on my experiences, rather than offering anything useful Searching images for "axis kite foil" used to turn up my photo in first spot, but now for me it's the end of the second row This topic is interesting to me because I've ridden two different foils of one brand, and one has whistled like a steam train, the other has been completely silent. We've got a guy with an Alpine foil that whistles so loudly you can hear him literally hundreds of meters away. He's swapped the wings and it still whistles. Another guy with the same foil is silent. Why? Is the whistling related to vibrations, or is that something else? Both my Axis foils are smooth as silk through the water, but the kite foil would squeak softly if I loaded it up in a carve, and the S-series has a gentle whistle when running flat out. Neither are as bad as the Alpine, which is bloody loud. So I think it comes mostly from the stab, or interaction between stab and water flow around mast and stab. Is it vibration you're feeling too, or just the sound? With the tape residue on the other wing, it was feeling like I was driving over shingle rather than any noise...
  9. What's everyone's go to kite in patchy light wind.

    That trend came and went in a hurry -- pretty sure the hint is in the name: SUK
  10. What's everyone's go to kite in patchy light wind.

    Been there done that. Oh, still doing that. Just with a smaller kite You could try SUP foiling in summer. I'm almost tempted, except for the lack of waves.
  11. Naish Foil Board

    Square of the trailing edge? I had tape residue on my other wing, and I could feel that make sure everything is smooth...
  12. What's everyone's go to kite in patchy light wind.

    You mean, like a Sonic 18? Or a Sonic2 15? Did my collection of Speed3s not count or something The difference in the wind needed between riding the 21 (or 18) and switching to the 10m was just a couple of knots. The difference in fun, much greater. The gif down there is a GPS trace of how I like to foil. That's not going to happen in 6 knots ... heck there's not even rideable swell till 12 knots.
  13. What's everyone's go to kite in patchy light wind.

    Been there, done that, got the badge for long-distance swimming it's just not fun. You can't ride at the kite, cos it stalls and a foil just noodles into the water. So if I can't foil with the 10m tube, it's just not worth the candle. Even then, the bottom end is still a bit ho-hum sometimes.
  14. Bye Dad.

    Sorry to hear that. Best wishes
  15. What's everyone's go to kite in patchy light wind.

    Oh, didn't notice the forum this was in. Still, if I have to use a kite bigger than 12m, if rather not, no matter the ride. And yes I have ridden a buggy. Why do you ask?
