  1. Someone mention my name .... sniff sniff .... . Hi Pari, Sorry you lost your job, quite a lot of us got shafted recently. Unstable times. Joel is right, stress analysis is my professional speciality. There are methods and software tools to predict and design for stress, there are however some perhaps uncomfortable truths. So you have the geometry and material — good start. To predict the stress response (will it break), you need to know: 1) material stiffness, if it is composite, stiffness in various directions and the interaction of them. 2) material strength 3
  2. Hi Renato, Southerly Buster here. Joel is right I have built nasa kites from 0.75m^2 up to 9 m^2. Must say they are one of the most challenging kites to fly. It is usually the trailing edge that begins to flutter if nit enough backline tension applied, too much and she flies backwards. They are just for giggles kite or for pure down winders. They have very poor upwind er um no up wind performance. If the nose is collapsing I would say too much tension on the bridle, not the front lines but the bridle. Did you sew in those little straps on the nose underside to the top of the nose? That plan yo
  3. Good move Joel. So this .org will run in parallel with the FaceBook Group I assume. I like the revamped look, putting pictures of members on the various forum section headers.
  4. I was lucky enough to be working for an essential service when the COVID19 lockdown commenced here in New Zealand, so are still working and earning money. Have not been kiting or flying my RC gliders for a few months now, have been putting my efforts elsewhere, now concentrating on my music productions. Funny 7 years ago when I started making videos of kitesurfing etc., looking for music to go with it, vids got silenced for using copyrighted material (oops, then switched to a paid service) and thought, why don’t I write my own music — not so easy. But I have been steadily working on music com
  5. @andy666, things over in my neck of the woods are fine, road traffic greatly reduced as no one is supposed to be out driving unless directly to/from work for essential workers or to get essential supplies. A lot more people out walking the suburbs to try and break up the monotony of staying at home. The intension of the lock down is, when it commenced who ever was in your house that is your cell, no wandering off to other people's places, all people outside of your cell keep at least 2 metres away. Working at a Pet Food factory, I am an essential worker, so business pretty much as usual for me
  6. As I gaze over my crystal bass, I see the 730 report, a quaint timber shack on a quiet beach side on the East Coast of Australia, a flickering of a small kite out side, the camera pans into the door. It's like the Tardis, a museum of Peter Lynn kites. A sewing machine in one corner and the odd collection of boards and buggies in the other. Andy then appears and explains how the collection came to be. Nice Video Andy. From FlySurfers to PL Arcs, a strange fanscination with the odd ball kites. I still have my FARC16m and fly it on occasion, though sadly at the moment they are all tucked awa
  7. Simple, the leading edge is facing down hill and that is where the apparent wind is coming from. Wings do not fly well backwards. Gravity pulls you down hill, that is what generates the apparent wind.
  8. Board and rider in action on an inland lake, lake Coleridge, South Island, New Zealand. Was a good day out, very light winds about 5 to 6 knots, powered with my FlySurfer Lotus 18m^2. Was amazed how smooth the ride was compared to hydrofoiling in the ocean.
  9. My SpeedWeek 2009 and 2010 are still going strong, a bit faded though. They were the orange ones. Ya so 11 years usage and still holding up, must be the colour .
  10. Any one notice he twisted the bar around to reverse of what we usually use on land when he was flying down the hill, i.e. kite facing away from him? Good find Joel.
  11. 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
  12. 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.
  13. 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?
  14. @Randy, nice of the car users to not use the car park, err um your personal kiting play ground . Nice spot by the lake.
  15. 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 th
  16. 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?
  17. 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 trie
  18. 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.
  19. Ya, well some people have no sense of humor.
  20. 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
  21. Good one Joel, next they will look where the UBS plugs in.
  22. 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 t
  23. 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.
  24. 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.
  25. 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.
