  1. I find the tops should be about 6.5 to 7.5 inches further out than the bottom as a good baseline. Some people will go further out, depends on handles and flying preference, but the above is a good baseline. I don't believe there is any merit in going less than that on standard equipment unless you like to hold the handles at the bottom or something really obscure. I pretty much use one of two knots on my top leaders which cover me from light wind to overpowered. When handing off to someone who wants to give this flying thing a try, I will usually drop only one knot back on the top for them to make it a little easier, but that's usually only when I'm on my heavier brake setting in lighter wind. Failing that scenario, I leave it right where I fly and give them the handles. Once you show someone how to launch correctly the setup is not a problem.
  2. I also use them as backup beach stakes (after cutting it back from where it broke) Not often I use it, but it happens
  3. And there you go .... variance across the same anatomical structure resulting in different outputs, but with a consistent principle. That principle is what lets one pick up any handle and find neutral and know you only ever need move a single knot. I've played (at length on each iteration) with different handle bends, foam thicknesses and foam position (among other factors), and each has their pros and cons. Where I feel I have a leg up on most is that I am aware of the differences and what I gain and lose on each variance of the possibilities. From there I can pick which one I feel is the best mix for me. Truth be told, I'm actually in the process (have been for a few months) of circling back to where I started to revalidate things against the knowledge I believe I have gained through the process.
  4. I have made a number of leaders since that thread, and different handles have different adjustments depending on when they were made. I set my neutral based on flight characteristics not a specific number. Once the neutral has been found, I am at the most efficient setup for my hand and body structure and moving 1 knot either way will account for environmental variables. This way I can pick up any setup from anyone with any handle, and as long as the top leaders are long enough, I will find my happy neutral based on the handling within a few minutes. As far as upright hovers go, I prefer to be able to hold the hover without having to constantly pump the kite constantly (assuming there is sufficient wind force) but I do want as much brake as possible for more precise control. I have never had any trouble maintaining speed (positive or negative) relative to others around me with the exceptions of those who fly too little brake and have their kite running wild all over the sky with little control.
  5. As a rule of thumb.... Light wind ... heavy wind .... I don't move more than 1 knot on the top leaders, and that's almost exclusively only for strong winds. Overly strong wind aside, the setup for most efficient and effective use of the air pressure is the same for normal or light wind - this is sheer physics. If you move more than a single knot either side of your average setup then I would question the setup to begin with
  6. Valid, but given the tensions and observations I saw and the frequency I felt ... unlikely. Curious indeed
  7. Hi Mark The kite flew evenly and without any asymmetric tendencies, with the exception of that pulsing coming down the lines. While I am capable of adjusting for a fair difference if something is out, I never felt like I was compensating for anything and the kite tracked as straight as any other. I have a decent understanding of what is happening on a Rev sail, but I suspect you are far more knowledgeable than me on the science of aerodynamics so it would certainly be interesting for someone like you to take a look at this ... even if only for curiosity sake. The trailing edge was definitely not fluttering and the origin was in the sail itself as opposed to the edge. I did notice one or two odd creases that don't exist on the B/Pro sails but nothing was rapidly moving in flight that pointed to an obvious answer. It was curious to me, which is why I got additional opinions to make sure I wasn't imagining things. I didn't spend hours on it because I don't plan on owning a NYM, but if you get your hands on one and figure it out I'd certainly like to hear about it.
  8. @makatakam Seems to be hit an miss from what I've seen (see my response to Kent above). The reason I got on the handles at WSIKF was because I wanted to verify what I had heard with my own experiences and not take the word of others. I couldn't tune it out and in one instance it was almost exclusively on the right side of the sail. We were on the beach so I wasn't able to strip the frame and do left/right comparatives. I know I flew the 3-vent when the vibration was on the right hand side, and if memory is correct the other sail I flew was a 2-vent model. I know I did not fly the standard or 1-vent model at all.
  9. Absolutely Kent, no offense taken Mark (Air-4-ce) has not had this with his team NYM sails when I last spoke to him about it and I know others have also been fine. I have seen mentions of it before and the 2 sails that I tried out at WSIKF both suffered this problem. One of the sails only suffered this almost only on the right hand side. I looked it over, made sure everything was setup and tensioned right and even got a second and third opinion with no luck. I stood under the kite while someone else flew so that I could look at the filled up sail in motion (the vibration doesn't exist while stationary) and there was no trailing edge flutter at all. From what I saw on those sails my assumption is that there is probably some excessive slack that can creep into the sail during sewing that only becomes apparent once the sail is loaded and assumes it's wind filled shape. I am not sure if frame choice has any impact on this or not as I only flew with the frame that was in there when I got handle time. Some slippage in panel layout during assembly could also explain why you can get a different feel left vs right as well. This would only become apparent in flight and would not be visible during assembly. Again, that is just my assumption based on my limited hands on time in combination with the experiences I have heard from others. Not everyone experiences it and I suspect many don't know or don't care about the sensation - those who's sails I tried either didn't realize it was odd or didn't care about it since the kite flew fine for them. I fly Pro sails so I know every sail is the same as every other sail. If the way the 3-vent loads doesn't bother you and the potential vibration isn't an issue for you then the NYM is a competent sail and by all means one should feel free to go right ahead and purchase it safe in the knowledge that we'll all still fly with you and you'll do just fine in team flying and we'll all have fun. I'm certainly a believer that Rev should put out different sails for different preferences. We already have the B/Pro, Polo, NYM and now the Diablo sails that will all load differently and have different flight characteristics (load, rotational speed, tracking, etc). I personally would love the see Bazzer and JB given freedom to improve the Pro (there are definitely some refinement possibilities) as well as develop something above Xtra and below standard in the 1.5 platform. In the end you should fly the sail that makes you happy depending on whether your priorities are aesthetic or performance based ... we're all going to get together and have fun regardless

    Full sail for sure .... Once the wind is up I switch to the mid vent with 3 wrap frame - a little venting goes a long way to making me look smooth and sharp

    Just remember that low wind flight is dictated mostly by pilot ability and equipment makes up a small percentage of that equation. I use the heavier frames regularly back home because I have to fly on shorter lines and get some strong wind, but when I'm in the USA with longer lines I don't need it very often.
  12. Just to add to the above and clarify... The NYM is the latest/greatest produced by the Rev factory (some may say the B is the best factory but that's a different debate), whereas the Pro is the top of the line and hand made by Bazzer Poulter. As Kent alluded to, there is a lot of things that go into a Rev that make for a more naturally refined experience which may or may not be worth the money depending on what you want from a kite, the level you plan to fly at, your style of flying, how much you want to push the limits, etc. Like all revs in the line up, they all fly pretty decently (yes people, that failure to do something is probably your fault .... lol) but there are subtle differences that do make a difference to characteristics and performance. One thing I will mention about the NYM sails that I have spent time on (two different ones) is that there is a constant vibration coming down the lines from the sail despite not hearing any trailing edge flutter and I could not tune it out. On one of the sails it was almost exclusively on the right hand side and only subtly there on the left. I have spoken with other who have also experienced this (some sold the kites because it was not something they could live with) and others (very experienced pilots) who have not experienced this at all ... so your experience may vary. Despite that oddity the kite does still fly and I was able to adapt and make it do whatever I needed to do with it. Granted, I was not pushing the limits since none of the NYM that I flew belonged to me, but it was functional in what I needed to do. For me, the 3-vent punches the heart out of the engine with the location of the inner vent (personal preference) and the vibration are too big of an issue for me and I prefer the quality and natural precision of the Pro series. Will the Pro, NYM, etc make you fly better .... absolutely not ... but once you know how to fly properly, then the details start becoming relevant.

    @MisterNixter If you can hold the 4 basic hovers and have basic flight control then you're ready to get in line - it will only help accelerate your development

    WSIKF 2015

    There's always team flying going on .... I don't fly 32-26 hours each way to fly by myself ... LOL
  15. Got your PM and sent you email
  16. If you got your B2 from Gareth he should've passed on my contact details to you... If you prefer someone physically in JHB then contact Jacques for hands on time. He's down the south coast this weekend (I'll be seeing him - probably Sunday) so you'll need to check with him when he's back in GP since he travels for work.

    WSIKF 2015

    Prep the beach and weather for me ... I'll be there on the 14th or 15th
  18. Assuming the Rev lines are LPG, Shati or something similar ... you would find the power kite lines much thicker and with different properties. Those line characteristics will have a much bigger impact than length. FYI ... I regularly hand off my rev on 50' lines to interested people and get them going without any major issues. Difficult (as opposed to steep) learning curves are usually the result of not having the right information which results in difficult setups, objectives and methods. They could also be the result of a poor environment to learn in. I'm going to find out which one of those is my problem regarding dual line when I get together with JB at WSIKF. He's either going to confirm that I'm not very bright when it comes to duals or that I'm on the right track and my local conditions just don't support it very well
  19. I generally fly 30' or 50' at home with occasional 80' should I find myself at a suitable location. When I go to the USA to fly I usually am on 120' lines with everyone else. There is a very slight delay in response time from the kite due to the need to take up any additional line drag, but you would have to have a well educated hand capable of detecting small differences in timing and feel. If you're newer to flying a rev then you probably won't notice the slight difference. The kite doesn't travel any faster or react any differently compared to longer lines, it's just that the distance from one side of the window to the other is shorter so you move through the various zones of pressure 'quicker' due to them being smaller. Basically, everything is the same except for the length of the lines
  20. The ninja will be making a return...
  21. I fly my Flexifoil power kites with brake tension like my revs. Any 4 line kite will have more control with tension on all 4 lines
  22. Much easier to back off an inch (MAYBE two) from my setup when I give them the handles and not say a word. When you start, everything is just as 'difficult' and anything else since it's a new skill .... teach them correctly from the start. The only time anyone has struggled with this is due to low wind (and slacking brake will further reduce pressure/control) and I generally have people flying unassisted within the hour.
  23. Glad to see I'm not the only one who feels the current sleeves are functionally lacking and well below par.
  24. Also be aware of what your chosen environment will do to your wind, or lack of wind. Some locations will look cool, but the wind will be messy, turbulent and switch directions on you every few seconds. Learn the environment and it's conditions while you build the skills. Once you have the skills for that then any environment is game.
