Hi, perhaps someone here can give me some tips with the relaunch of a Nitro 5. I used my 12m in light winds (+- 12knots) on the weekend, and 9 times out of 10 could not get the kite to roll over onto a wing tip for relaunch bu pulling a steering line. When directly downwind, on its leading edge, the kite generates a significant downwind pull as well, powered or de-powered. When pulling a steering line (even grabbing above the line attachment point) the kite starts to rotate into the relaunch position and then stops. The only repeatable way to get it to relaunch was to get it to roll over onto its back, but the only way I could get this to happen was by standing in the shallows and taking four or five quick steps (almost running) towards the kite.

If I look at the kite when it is downwind on its leading edge, the point where the front lines attach to the spider bridle is quite a distance above the leading edge (off the water). So pulling the front lines just causes the kite to move towards you in a parallel fashion to where it was before. I reckon a 5th line would do the trick, but is it necessary? Any tips would be much appreciated.

I've just watched a video showing a light wind relaunch of a Nitro 1 - . I tried the one steering line/other front line technique, but I did not grab enough front line, I'll have to try that next time. Also another thing I didn't even think about was the reverse launch. You can backstall the Nitro 5 quite easily, so a reverse launch should work-I'll have to give that a try as well.

U may have been in conditions less then 12kts or the bar may be out of tune. Check bar first, if it is tuned then conditions may be less then you expected. I've relaunched in 12kt conditions on 12m nitro5 with no problems. If wind falls below 12kts then reverse launch is your best option. There are many good videos on reverse launch. Basically pull both back lines hard while kite is downwind LE down. If wind is super weak you may need to pull in with a couple of hard pulses to get kite high enough to turn it over in the air. Once kite is in air release one of the back lines, the kite will then turn and shoot up, brace for the pull and you are good to go.

Just saw ur second post. The nitro5 didn't backstall even when I tried. Definitely check your bar tune. Having said that there are a couple more factors that can cause issues. Were you flying in the rain? The added weight of soaked material can affect flight. Also if this is your first couple of sessions on the kite, double check to see if there is a twist in any of the bladders. My 12m came with a twisted bladder and caused some funky flight characteristics. It was an easy fix.

Thanks for your response. One of the first things I did when I got the kites was check the line lengths, all lines are the same, so no problem there. It wasn't raining, and no twisted bladder either.

My way to relauch the nitro in lightwind conditions: Bar fully depowered, pull in both frontlines until the kite rolls into belly up postion, then pull one steering line to catch wind with the tip.If the kite stands up carefully let got the frontlines and start. Never successfully made a reverse lightwind launch on my nitro4 ... Nitro V4 is a bad lightwind starter, looks its the same one the V5.

Oddly enough, I had the same problem with my 12m v5 too. Except I felt the wind was stronger about 15mph and going down wind with a current in the same direction made it difficult. Normally in the past I would sheet the bar out to the stopper ball and pull on one line to relaunch. I found this version of the nitro relaunched better sheeted in to the chicken loop then pull on one line for relaunch. Try it.

I tried with the kite powered and depowered on the cleat, bar fully sheeted in and sheeted out with both cleat settings, still the same result, the kite refused to roll onto a wing tip. I think the source of the problem lies with the spider bridle attachment point, it is quite a way off the water. The kite has to pivot around this point, and the kite is exerting pressure above and below the pivot point, and therefore requires a lot more wind to roll it over. Next time you have your kite in the leading edge down, downwind position, have a look at that. I think a 5th line would solve the relaunch problem by giving the kite a rotation point that is at water level, but this is adding complexity. Pulling on the 5th line would allow the kite to easily roll onto its back. Maybe pulling a couple of meters of safely line (with the single line flag-out option) and pulling on the opposite steering line would also work, but that would limit your relaunch to one side only (not a problem in open water) and also you would have to be careful of line wraps.

With regards the wind strength I was trying to relaunch in, it may or may not have been 12 knots, but it was regardless enough wind to park the kite without movement once it was relaunched. If the wind is strong enough to park a kite wherever you want in the wind window, it should relaunch in that wind without problems.

Relaunching a kite in light wind conditions can be tricky. I have had to swim in several times as I always seem to crash my kite on my outside tack :cry: . The best method to relaunch the nitro is the one in the video. Pull the opposite front line as the outside line your pulling depending on which way the kite is closer to launching. I suggest to practice these techniques in shallow water in light wind before it happens in the deeps of the ocean with current. When winds get marginal I try not to go on too long of tacks and also always keep the kite flying so it doesnt fall out of the sky in the lulls. I usually have to self rescue a couple times a year so I'm always prepared for a swim in light winds. I also always like to ride with a friend as they can grab your board and help you out if things get hairy.

Maybe, this is an issue with the spider bridle?.. Anyone tried flagging out on stronger winds?
