 Sat Sep 15, 07 12:22 pm Problem with 9M Waroo inverting after crashing?? |
 |
|
Just finishing up my first season kiting; what a great sport.
Getting to that stage where I am crashing my kite again (trying moves/tricks/jumps) but having a frequent problem of the kite inverting after hitting the water; bridles cross behind the wing tips. Eventually with enough pulling on lines I can get the bridles free but the kite is literally passing through the front bridle to free the lines. I eventually get kite flying but always with the result that the outside wingtip lines have crossed with the center lines. Then have to head back to the beach, land the kite and undo the lines. First time I thought it was a fluke but after 1/2 dozen times its becoming a pain.
I don't think it is a inflation issue; I have a guage an pump the kite to 7-8psi.
Any tricks or words of advice on how to prevent this happening? (Yea I know don't crash the kite...). Seriously is there one set of lines to pul verses another of something to do immediately on impact?
Thanks |

| I'd like to suggest something but I can't really picture what's going on, regardless I've never heard of this happening before. Can you draw a picture of it? Is it an '07 Waroo? |

I'm not certain on this, but it seems like the Waroo is supposed to be pumped up to more like 10 psi? You might want to check on the Best forum though, before you pump it up that hard. Also, what year is it? If it's an '06 you should probably have Airtime do a reinforcement on the LE... |

No good at drawing pictures but imagine that you have your kite rigged on the beach with the line out in front of you. Now take the kite and pass it between the two front line doing a complete 360 degree forward rotation and set the kite back down. Your back lines are not cross with your front lines.
Or from the other end take your bar and pass it through the front lines above the depower strap and then lay your bar out. Again the lines will be crossed.
When the kite is falling the kite loop foward doing the same thing and you end up with crossed lines.
FYI its a 2007 Waroo. |

Not sure if this will cure the problem but I don't think it will hurt...
Pump your leading edge rock hard. 10, 11, 12 pounds; should "ping" when you flick it with your finger. You should just about be standing on the pump when you're done. Waroo's need to be pumped HARD!
When you crash first thing you want to do is push the bar all the way away from you and pull the depower strap a couple of inches. Then rotate your bar until the lines are uncrossed going to the kite. (bar is upside down now). As the kite rotates on the wing tip to relaunch rotate the bar to keep the lines straight and get back to normal.
If the kite has landed with the leading edge facing you try to figure out which outside line to pull to swing it around to get it facing straight down wind again then go through the relaunch procedure.
If the kite has landed on it's trailing edge you need to be quick and swim against the pull of the kite to keep it from rolling over and crossing the lines. The best way out of this is to reach up and grab the 2 center lines at the mouse ears and yank in about 3' of line. Keep tugging just like when we were kids flying a regular kite and you should get a hot launch straight up. Make sure your hands are not wrapped through the lines when doing this!
If the kite is rolling on top of the water it's going to get the inner and outer lines crossed. This happens more in easterlies as you tend to float towards the kite and the lines get slack. Learn to backstroke.
Good luck!

No question that the slack lines are part of the problem as its when I crash the kite while heading toward the kite fast and have slack lines (riding waves, doing toeside turns or jumping) that this problem occurs.
Are you sure about pumping the Waroos to +10psi !! I already had one Waroo blow a leading edge (an 2006) and it was at far lower pressure than that!
Thanks for the suggestions |

The pressure you see depends on the accuracy of the gauge, but yeah, I pump mine to 11 all the time. I have a 2006 9m, 12m, and 16m, Waroo with a LOT of riding hours on all of them (200+ hrs each on the 9 and the 12) and I always pump them this hard. I haven't had any problems with any of them.

I've noticed that when learning a lot of people will crash a kite but continue to ride their board using their momentum. This typically brings you closer to the kite and slackens the lines (allowing your kite to roll or invert).
Make a conscious effort to just fall into the water as fast as possible if your kite goes down. That will help keep tension on the lines and prevent the kite from rolling. Better yet, if you are still riding the board after the kite goes down, lean back (upwind) and try to put even more tension on the lines before you fall. |

Tension on the lines is key, as everyone has said before. If you're riding and the kite falls out of the air, edge away from it as hard and as fast as you can.
As far as leading edge pressure goes, I test mine by putting it up on a tip then trying to push the tips together a little bit. You want it to put up a lot of resistance, because that's how stiff the kite's going to be in the air.

I would not go as high as 10psi. I had a 9m 2006 that I had been pumping to 7 and was told it would perform better at 10. I started pumping to 10 and within a few sessions my leading edge blew out on a hard kite fall.
8-9psi has worked well. The only problem I encountered was deformation (flattening) of the kite in high winds. But you can learn to prevent this by sheeting in to hold the kite in bow form. 2007 Waroos fix this problem but the kite doesn't fly as nicely as the 2006 (imo). Wait for 2008 if you're thinking about upgrading. |

It seems that some 06 waroos have some serious stitchign issues and if you pump them up rock hard the seems start busting. I have a 5 and 7 meter 06 that have stitching issues so I don't pump them up hard - however, I also have a 9M waroo that is an 06 and I pump that up way hard and I have had absolutely no issues with stitching. Just my two cents. |

Ahh, I hadn't heard of the stitching problems. Mine are all '06's and I don't see anything letting loose on any of them. I've been pumping them rock hard and still no problems.

The offical word from Best and their reps was to pump it very hard, and that would prevent the kite from flexing/inverting which is what does the most damage to the stiches.
When you pick it up on the beach it shouldn't flex or bend at all. |

Ditto that! I pump my '07 9m & 13m rock hard and have never had an issue! I also must add that I have had my fair share of wipeouts.   |

Great post; The comment about continuing to ride the board after the kite falls is right on in my case. I just sort of coast in slow motion until I sink. Its kinda fun but clearly results in slack lines.
Did it twice today on my 7 M (pumped rocked hard) and same problem of rolling; inverting and then twisted lines.... |
