Stacked Kites

Postby cbunn » Sun Dec 04, 2011 9:16 am

I have recently been trying to solve the problem where I start a session in light wind on a large kite only for the wind increase and be forced to come in and change to a smaller kite. To combat this I have been stacking a 17mtr on top of a 10mtr and have gerry rigged a pull release that ejects the 17m as the wind increases. There are 2 problems that are proving hard to solve:

1. The size difference between the kites causes the 17M to kink in the centre and fly unpredictably as the wind increases but not enough to eject. FYI I have been using wooden extension planks on the edge of the 10mtr to attempt to address this issue but find this not ideal.

2. The gerry rigged 17mtr ejection system is not reliable quite often I am left with a line attached and the 17mtr flagging out off the top of the still flying 10m rather than totally jettisoned.

Any suggestions on a solution to this appreciated?

You may need to fine tune your extension planks. Choice of timber is also key. Teak is particularly noted for its aerodynamic performance.

I can only guess without seeing details of your bridle, but if you are using explosive bolts in your release system, you may need a secondary mechanism. That trailing 17m kite can make some wakestyle tricks rather challenging! Perhaps you might consider injecting gasoline into the leading edge, and inserting a spark plug to ignite the kite should the primary release fail.

HTH.

Try using more lube on the thrustulator.

I would seriously try packing the bowl a little harder, and drizzling a little hash oil on top! :jap:

DUDE !!
I hadn't given the coffee time to take effect this morning,when
i read this post.

What was left of the first cup went all over my lap because i
laughed SO hard !! Thanks for that

UAH-- What your doing is NOT a solution ; but seriously, i'd
Really like to see a picture of your Stacked Kites.

I always wanted to do that with my PL venom's, (the 16 & 19m)
just for Fun !

BUT on another note -- at least your Trying !!
ANY solution ---is better--- than NO solution !!!
It separates You from the Sheep that are willing
to just submit to current state of the art.

Everyone Wants a kite that works in light wind
and is fast enough to go in the stronger stuff.

Your going to take a Lot of Shit for your post ; as
much crap as i'll be taking when i present My solution
to the same problem this next spring.

But Don't let that stifle your imagination ...

Or try to mount 2 or more nitrous oxide jet engines on the tips and maybe you can manage to be in orbit then die after attemting the come back to the atmosphere and stay in history !!!!!!


serious man... you can very easily get killed or drown with normal kiteboarding. !!!! :oops:

YEP -- your correct .
& you can get killed sitting at a stop-light, in a car.
Ya can die eating too many potato chips & beer, bad
for the heart & liver.

& Yea, i agree that his solution probably wasn't the best !
Actually, "Wasn't" the best !


At Mohave the wind sometimes goes from 13 - 28mph.
Most riders will rig for the 22-28, then sit in the water waiting, with
their kite doing figure 8 - down-loops because there isn't enough
wind to fly it any other way.

My 2008 13m Ozone Edge can handle the entire range
and keep my 142 Underground, planed off with my 212lb.

The newer 2010 13m Edge i just got, will Not be handling the 28mph
so well.

Rather than just Deal with it, I plan to change it ; and like i told --cbunn-- :
"I'm Certain I'll be taking Just as much Crap, for Daring to be different.

& my solution may not work ... ; but getting Laughed at isn't going
to stop me from trying !!

Thanks Weetabix, I was thinking teak would be a bit heavy, I have some deck chairs made of teak and super heavy, however you did make me think of shaping the planks into an airfoil, will give that a try.

A secondary backup for the ejection system is a good thought, i need to think that through, fuel in the leading edge and a spark might be a little extreme but would be cool to see the kite burst into flames as it fly’s away, would be safer too as there will be no kite drifting down wind.

Anything else comes to mind let me know.

Cheers.
