Never has a video cost me so much in time and expense. I hope its not a total waste of yours.:)

Giving the Chrono 11m a fly in 3-5knots 5DB4CCBE-DAC4-44AE-9C62-A94816A14EBD.MOV

If there's no wind, you can get squashed like a bug by a giant mad max toilet plunger. Or surf.

I have the 19mtr Speed 2 "Silver Arrow" The line lengths are NOT equal on this kite!!! Now I was flying this quite a while ago but.... i'm fairly sure I let the front lines out 90 to 100mm on their adjustment above the trim (if you have the Flysurfer bar) or make pigtails for the kite end. I made the very same mistake when I got mine. I tuned/shortened/adjusted them back to even line lengths before I flew it at Yeppoon and it was a pig to fly with no power. Stopped a few kilometers up the beach and spent some time shifting it back to it's original setting, where it was when I got it and away it went. I had been corrupted by my Ozones equal line lengths. and just as Kami says gotta be light on the bar. That's pretty tough as it's heavy as hell and takes the whole universe to turn 180 degrees even with a 800mm bar. I would run out of bar movement in the buggy and would just tent pole the bar!!! (grab a handful of rear line and lock it down onto the bar towards the centre to get more throw on that line. (A maneuver shown to me by @gannet to get my Ozone R1's to almost propeller on the spot without fluttering or the tip folding in. You can hear me commenting to Gannet at the start of this video on its maiden flight. (Before shifting the lines "back"? out.) The first frigging dog in the video bit me on the leg that day. The bitch of an owner didn't even say sorry, so I dropped the kite down low, went slowly along "tea bagging" the dog and let it chase me 5 kms up the beach. Last I saw of it it was lying panting under a palm tree out of the heat while it's owner walked the beach whistling it for an hour or so. Didn't see them for the rest of the month I was there.

I'll let you fly them in Kingston mate!!!! I bought them last Saturday evening.

Thanks guys, and appreciate those who came to the funeral. The morning before the funeral I dressed Dad with the family and he went wearing his Extreme Kites Buggy T-Shirt underneath his suit It has gone from being very real and being incredibly hard, to just a surreal feeling of emptiness. My kiting gear is still stored at his place, so it's a bit raw at the moment to go load up the buggy on the car without him to go for a kite. The aim is to enjoy Christmas then get back in the buggy in the new year, and have a big gyros.

I've got a 6 and 9 . Love the 6 but 9 doesn't suit as they are for sand dune only buggying and want a faster turn speed. Dunes are tight here. I'm going to trade 9 back for a 4 mtr. As far as power, awesome. Low end grunt is good. Good wind range and depower. Been using modded PL singles for a couple of years but now want depower.

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.

I’ll come up with some proposed dates and we can see which suits the majority of people who want to go.

No. Speed 3s don't count As I said, each to their own. I enjoy bottom end foiling, sea being pond like and having it all to myself as it takes a different skill set. I don't want to have nothing to do mid summer living next to the beach just because I only want to use a 10 lei.

Hi guys great forum I am stoked to b here amongst people who know their stuff coz I am a newbie. I aspire to jump in sand dunes n mountain board on the beach. I have been learning with an ozone 1.6m trainer and recently a p Lynn 3m hornet which I scared my newbie self with lots power. So I have a question please, about depower kites- how much of a kite's power is lost when u sheet right out? They look so manageable compared to a fixed line kite? I Think I want one thanx

New single skin kite from Ozone for 2019 called the "Explore". It will be available in 4, 6, 9 & 12m and looks to be aimed as direct competition to the FS Peak. Manufacturer's blurb: "The new Explore by Ozone has something to offer for everyone. Consistent pull through the wind window, instant de-power, minimal upward lift, relatively slow flying speed, and damage-resistant single surface design make the Explore an amazing kite for entry level and intermediate riders. Advanced riders can push the boundaries - tight and dynamic or slow lazy loops can navigate difficult terrain while excellent drift allows riding down slopes without worring about the kite. For experts the lightweight design means it can fly in very light wind, allowing you to work the low end efficiently without having to worry about keeping the kite in the sky. The proven Re-Ride System means you can land the kite quickly and safely." I was thinking of getting the 12m Shaman 2 as a low wind engine but it looks like I'm going to have to wait a bit now. https://ozonekites.com/products/land-snow-kites/explore-v1/ https://vimeo.com/293139314

@Grants - @kneebusteris located in Darwin. Road trip straight up for you guys!

Newest build. A Mesh called Winter jacket (Because the wind goes right through it.)

It is VERY possible that I got it wrong me being an old fart. As I did have to readjust back to where they were when I purchased it. (Second hand but in mint condition) Cheers for that Kami.

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.

I have only flown a speed 2 once, but yeah, they do pull like a truck. It’s what they are known for. The mixer test only compensates for variation in the mixer. It does not compensate for stretch/shrink in the other bridles. (Normally shrink or the rear bridles) i would try restretching the bridles to return them to their original length. There are instructions online on how to do this. Good luck.

Yep, i tend to agree with a Trampa deck. Maybe it's a bitsa board, or an old style Trampa when they had similar matrix trucks to MBS. I also can't tell from the wheels. Anyway, looks solid enough. A bit of rust clean up or new kingpin bearings and should be good to go.

My first "buy" from Gumtree and this week I will obtain an un-used Prism Nexus Stunt kite. Couldn't say no to the $10 price tag! Thank You @Bill who will "do the deal" for me (might not be un-used by the time it gets to me - go on...have a fly) Proper Job!

Some years ago we rode under a super moon! I have a video somewhere. It would be handy to use lights + a red light on the rear of your buggies as its hard to gauge on a moonless night whether someone is hurtling towards you or not.

Just noticed that Extreme Kites has 3,999 members as of this evening.

4000! - @Jacob Wilton makes the 4000th member of Extreme Kites! Welcome to the group Jacob!

4 stack of 6' Flexifoil Powerkites. A 6' version of these. (These are a 10' stack.)

Love it! Love it! Love it! Soooo many new angles. And it looked like you were moving pretty fast. My son has a Fusion and I know how much can be involved with editing. Well done. You've set the bar very high. Sorry to hear about our camera.

Vertical or horizontal makes no difference as gravity makes no difference here on the formation of the vorticies, and it is the vorticy formation alternating between either side of the foil that causes the vibration. Surfaces being further apart, yes agree. I thought about this too, there must be some sizing effect going on. If you zoom in close enough there will always be a blunt end of the trailing edge. I suspect the characteristic length would be the boundary layer thickness. I expect the above article was an A to B comparison, same foil size, just alter the taper angle. So at some point a blunt end would make no noticable difference. Agree some of these sharp edges look nasty for rider safety. Reckon the blunt hard trailing edge plus the relatively soft tape I used is a good solution, just a mater of find tape that lasts long enough. Helicopters use a special tape for the leading edge for abrasion resistence ... hmmm. Yes the tape was double backed onto itself to creat a thinner trailing edge. At the moment I am thinking, don’t mess with the foil, just use tape, main motovation is rider safety against cuts. The tape lasted well for one session, will see how long it lasts. Longer term solutions would be tapes with heat activated glue applied to the resin coating. I suspect if the foil wing and mast were made of a very heavy highly damped material with zero vibration transmision you would not hear the wistling. Apart from the very low frequency vibrations that one would definitely feel through your feet, the high pitched frequnecies may be more noticable depending on the stiffness and mass of the mast and board, if the whistling frequency excites one of the natural frequencies of the mast and board, then it would be clearly audible, like a sounding board of a piano.

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?

I applied some tape to the trailing edge starting on the top side level out extending beyond the trailing edge by about 2mm fold over and stick to the bottom surface of the foil. Humming gone (which I could hear and feel). The tape is very sticky, I use it for reinforcing my foam gliders, sticks like sh@#$/ $# on a blanket. Did not come off during the light wind session 6.6 to 9 knot wind with 18m FlySurfer Lotus.

Some googling, reading and applying some engineering common sense .... There appears to be a lot of “wive’s tales” and snake oil surrounding the source of the humming, but also a lot of good information out there. From my reading it appears the shape of the trailing edge is the most important aspect to reduce or eliminate the humming. As the two flow streams from the top and bottom sides of the wing come together at the trailing edge, where the vorticies peel off is the important bit. If they peel off consistently on either the top, middle or bottom then no vibraton; if they peel off alternatively between the top and bottom surfaces, this causes a vibration and this is what the hum is. From a Yatching design book, there are some guideliness to reduce or even eliminate this vibration, see below for extracts and source of the book: What I have is a rounded squared off trailing edge — not a favourable shape. So what I need is some thing like option 5 or 8. The fibre glass is wrapped around a shape like option 1, so as not to expose the wood underneath the fibre glass protective layer, I need to add some fairing to the trailing edge to make it one of the more favourable shapes, but also ensure I don’t make it too sharp to avoid cutting myself. Thanks @Kamikuza for the suggestion, it lead me to find the above information. By the way your name appeared in some of the searches . Looks like a lot of other foilers experience the same problem. Also one suggestion was to apply some tape to one side of the trailing edge to stop the fluctuatin of where the vortices peel off, might be a quick way to see if this is where the vibration problems come from.

Thanks! As the tide recedes the beach is naturally split in two down its entire length separated by a river of standing water. On one side its super smooth, fast, safe and free of obstacles which of course makes the entire experience as dull as dish water. On the other side however, its full of stones and parked kites, line sets and dangerous pilons, barking dogs and windsurfers giving me the finger. Happy days. Synchronise the wobbles to the music? Behave. xD

Thanks! You assume right my good man. The camera captures in 360. The rest is in post ( Adobe Premiere ), although the included Fusion software will hold the horizon for you, or let you chose your own Yaw, Pitch and Roll. Once you have selected those axis in three dimensions, everything then rotates around that point. Clever stuff! A very low tech solution for mounting the camera was used in all my shots. At first I used a thin steel rod as I thought it would cast minimal shadows, however it gave a noticeable bounce as seen in the video. I later discovered a broom stick gave super steady results and I learnt how to hide shadows in Adobe from YouTube videos. Regarding your picture, the broom stick was pushed into the end of the center strut before the kite was inflated. Once inflated, the bladder holds the stick rock solid. The stabilisation comes from sensors inside the camera that continuously record all the tiniest shakes and vibrations as data. That kite footage cost me my camera. Glad you appreciated it. xD Thanks! And thanks again, my mission was to stump you. You are not alone. The Fusion uses two lenses, one on each side of the camera, both are slightly off-set from one another and both record 180 degrees onto their own SD card. You then import the footage into the Fusion software which then stitches together the footage from both cards and in the process hides the camera's selfie stick giving the impression that its floating in mid air.

Great video, lots of contrasting camera angles. Though would have been nice for the camera wobbles to be synchronised with the music beat . Those rows of pilons on the sand must be annoying.

Too true!

Really impressive @RedSky. At the risk of embarrassing myself because I know nothing of the tech and don't know if this even exists but it looks like footage was shot from a drone on a programmed wireless tether?

oh mate, I missed them by that much. I phoned the lady this morning and they are Gond. hope someone here bought them, that has gotta be the gumtree deal of the year.

wooho!!

Sea trials are complete, took the board out into the surf with the home made rear wing today. Took some shims along just in case the zero angle of incidence needed adjusting. The lower angle worked to my favour, lifting later but at speed needing to be less forward on the board, so was more managable to control pitch at higher speeds. Gave a nice stable flight. There was a hum though, will need to investgate possible causes. And the rear wing did not break, ya hoo. After the sea trials: (No fairing added between wing and fuselage, might be the cause the the hum. Counterbores applied to the wood were a neat flush fit, but when the glass was applied, the precision was lost, so this might also be the cause of the hum by way of turbulence. All final brush strokes of paint applied in the stream wise direction, to avoid roughness in the wrong direction. Highly approximate, but I remembered the frequency of the hum, then when I came back to my car, by memory I sang the same hum and used the stroboscope on my mobile phone to measure the frequency. 146 Hz, rather low frequency. Foil thickness distribution was "eye" balled, so maybe there are some parts of it causing too negative a pressure, leading to cavitation which also might be the reason for the hum. The wing feels reasonably stiff so would not have thought the hum was due to the wing being too flexible. Oh and pumping the board works better now, used this once standing with kite to get the board quicker up to speed.

Sound great, it will be nice to meet up with you guys finally for a kite and some beers.

Welcome @alison melia The amount of de-power depends very much on the kite. Some do more than others. You should find as a rule that high aspect kites will give a greater range of power adjustment over lower aspect kites. Good to see you are slowly moving up to a bigger kite each time, a great way to progress. The skills you learn can be moved along as you get bigger and bigger kites. You will also find that the smaller kites move far quicker than the big ones, so if you are gaining skills on a small kite, you should have little problems going to a bigger one. The big kites move slower, and as a result produce power the same way. The small kites move quick, and produce power quickly, and are often the kites that catch you napping. For jumping wait till you have a bigger kite. 4+m kite. It will have more "float" (softer landings) rather than a smaller kite which will have more "pop" (faster lifting), but pop doesn't work on the way down, only on the way up. Depower kites are bigger than fixed bridle kites for the same power. So an 8m depower may equal a 4m fixed bridle kite. Again it depends on the two kites (high aspect, low aspect, race kite, etc). Where are you based? We might have a forum member close by that can give you some pointers or even a go on some of their kites. Hope that's help a little.

This January at Kingston in South Australia I was on my Chrono 18m2 in bugger all wind. In Yeppoon QLD at Easter I ran my ELF 18m2 Joker 7 kite. A quick video of @gannet trying it out one afternoon. Even the butterflies were overtaking us down wind that day.

Do it! book it in now. I've done 11 in a row and there hasnt been a dud yet.

Hey peeps. Just wondered what else you guys do for fun? Anyone have as short an attention span as myself? Kite skates to kite buggy to kite surfing to kite foiling and now this......it's just getting silly. Lol

From the man himself: http://www.kiteforum.com/viewtopic.php?p=1032882#p1032882 The thread got a little confused - I think someone was asking about the ring where the front lines connect (at the V), then folks started talking about the bridle connections. So Armin is talking about bridle connection ELC vs ring vs knot here. He seems to suggest making knots will reduce the breaking strength (makes total sense), but Kami (and I) have suggested pigtails, so that shouldn't be an issue. I still like the tiny rings best, but dang are they expensive.

God I’m an idiot. I was thinking you meant the little connection lines at the canopy

I was going to use them for clouser eyes but you're welcome to them. PM your postal address

Replace the pigtails with some nicely DIY ones, spliced from 3mm Dyneema. ELCs are best when they're lost at the beach.

Flysurfer web shop. Or just buy some thin bridle line and make your own. http://www.emmakites.com/index.php?main_page=product_info&products_id=444
