    Naish Foil Board

    Adding the shims made the ride go horrible, so took them off. They probably also added some nasty flow separation. @Kamikuza, your comment of don’t try and lean forward rather move your COG forward, makes no sense. Perhaps we are saying the same thing, when I say lean forward, I mean shifting my body forward which then shifts the COG forward. Yes I know simply pushing down on the front foot does nothing to balance the board out because the COG has not changed. At the moment the biggest helper for me was to reduce the kite size now that my skill level is better, that way I can depower more once the board speed goes up. Launches are a bit harder but I have the knack of that now. Also a kite with good upwind capability helps greatly to body drag out past the breakers in the surf. By the way, those FlySurfer Peak 4’s have caught my attention, some of the local foilers here in Christchurch New Zealand are using them in the surf with rediculously small kite sizes. Anyone try the Born Race Stars for hydrofoiling?

    New no wind toys.

    The first video of the one wheeled skate board, wonder how many face plants happen when the leading edge of the board digs into the pavement. Ouch.

    Soul on Waves

    Nice @Pari. How does it compare to the Speed III and Lotus IV? How many knots of wind were you riding in, surfboard, twin tip or foil board?

    Born-Kite StreetStar

    @Randy, nice of the car users to not use the car park, err um your personal kiting play ground . Nice spot by the lake.

    Naish Foil Board

    Adding the tape to the trailing edge of my stabilizer wing initially stopped the whistling and vibrations, but gradually started coming loose, which attracted grit and gave overall a rough surface finish. The result was that the hydrofoil slowed down and became prone to stalling. The stalling was evident by riding along nicely, as speed increased I needed to put my weight further forward, putting high loads on the stabilizer wing, then a sudden pitch forward without the wings exiting the water. So it was time to remove the tape and fix it permanently by filing in a sharper trailing edge. In the above example from "The Principles of Yacht Design" figure 6.3, I went for option 5, with the exception of instead a knife edge a 0.5mm radius. I figured the finite radius would be more wear resistant, more robust to the edge breaking off and friendlier to the rider (besides I do not push my feed on the wings to kick them out). I cut a bit into the underlying ply wood, so had to re-coat with West System resin, let it cure, then file, sound down for a smooth finish -- no humps. Then used wet and dry sand paper. Finally, used some cut & polish for buffing up car paint jobs. The front wing was getting a bit dagy as well, so mixed up some resin with filler, then got the same treatment as the rear stabilizer wing. The wings felt smooth to the touch. Gave it a burl yesterday in the surf. Straight away noticed the nice swish feel, so parasitic drag was significantly reduced. No more rear stabilizer stalls and usual speed was restored. Still finding trouble at the higher speed that I can not lean further forward to balance out the board to keep lift constant, hydrofoil exits water and I go for a swim. Will try some shims on the stabilizer to tilt the trailing edge up to get more down force -- currently at zero degrees. Also have in mind to make a new front wing, same method as the rear wing (plywood, hand shaped, covered in fibre glass), making the front wing a higher aspect ratio than the one that came with the Naish hydrofoil.

    The Distraction - Time Lapse Video and Music

    Thanks Mark. Will be on holidays in a couples of days, so more time for compositions, plus will be able to use my new audio to USB device for better recording sound quality. @bakersdozen, how is it going on your front with music?
  7. Haven’t posted in while been busy more with music compositions, but still kiting and slope soaring my gliders with my son Zachary here in Christchurch. The Distraction by Norman Freund https://youtu.be/0exNctKqQkc Special thanks to my son Zachary for helping out with the time lapse pre-processing and advice during the music production. No I have not switched to LEI’s ha ha, some one else kiting in the beach scene. Hey @bakersdozen, thanks for putting me on to the Reaper DAW (Digital Workstation). Takes a bit to get used to it to feel free enough to be creative with it. I tried putting the video together with Adobe Premier Elements, very clunky, wrecked the quality, too slow …. . So I thought why not try the video editor that comes with the music DAW, Reaper, hey not bad. Cutting up the video segments and synchronising with the music phrases is simple in Reaper since your composition is already there with all the cues and midi notes. The video quality in Reaper is good too. Hope you like it. Music only copy on Soundcloud at: https://soundcloud.com/norman-freund/the-distraction Regards, Norman Freund

    Low Wind Racing

    Hmm so I wonder what happens when the wind picks up, I can just imagine the foot pedals churning around wildly ready to mash your feet up. Perhaps they have a coaster mechanism like in push bikes.

    A hard day at work

    Ya, well some people have no sense of humor.

    Power Kite Line Sets

    line load is proportional to kite area, is proportional to the square of apparent wind, then the various proportionality constants depending on the kite design. For power kites, in my opinion ultimately depends on how much the kiter can hold down on load regardless of wind condition and kite size/design, hence why kite manuals say for typical 70 kg rider .... . For non-power kites, they usually will have an upper design limit on max wind speed, hence they would also state the line strength needed. So does a table exist to cover all kites — no. Dynamic similarity can help you though, so pick a similar kite with known limits on wind speed and line strength and you can figure out the strength needed for your kite, assuming we are talking about non-power kites, or pick a line strength based on how much you think you can hold down.

    Good one Joel, next they will look where the UBS plugs in.

    Best Kiting Food

    So @plummet was right ... want to loose weight and be healthy? Ditch processed breakfast cereals and ice cream. I used to have weat bix + cereal (out of the box) + bannana + 1 prune for breakfast, and other times the odd ice cream — then I weighed 73 kg. No more ice cream, breakfast now very simple: rolled oats boiled in water, add a little skim milk, add one spood full of home made unsweaten yugurt — after about 2 months my weight is down to target of 65 kg. You would be amazed on the amount of sugar those factory made and delivered in cardboard boxes cereals have in them. The first week of the change in diet, had me looking at the fridge often, not any more. The porridge lasts me longer than the previous diet — great kiting food.

    Lightweight Buggy rims

    I’ve experienced the same geometric wobble on my plastic MBS landboard rims, three of them perfect, one has the wobbles. Fortunately for me I do not go fast enought where it matters.

    If you are lucky @goshen might give you some lessons, he is located in Geelong, one of the best landboarders/kiters in Melbourne, he used to run Kitepower in Geelong some years ago.

    Hello. newbie Q bout depower kites-

    Great to hear you got s landboard. Ok so if you are new to landboards, you now have two new skills to master, board and kite. For the board, find a grassy hill and practice some down hill runs with board only, get you used to steering and balance. Also learn how to power slide so you can stop, but for the first hill not too steep so no power slides needed. As some one else said learn to go with the flow, so, if the kite suddenly pulls you forward, don’t fight it, squat down and leap forward to take the tension of the lines, then keep on riding.
