Stunt Kite - Uneven Turning

by Adam Carter
(Port Neches T, USA)

Q:

I have an older 2 line delta stunt kite. It was for beginners when I bought it (about $65 fifteen years ago) and has had its share of wrecks but still flies well. The spars should be replaced soon and a few seams resewn just to tighten it up, but the main problem I am having is sluggish turns to the left.

When I pull to the right it is very tight, but to the left is slow, and as it gets older it gets slower. It's always turned slow that direction since I have had it, but is getting slower.

I know it's time for a newer more advanced kite, but I was going to pass this on to my 11 year old son to fly and wanted to "tune it up".

Thanks!

I'm hoping that an experienced kite person, initials G.C. ;-) , will jump in here to help, since my own experience with repairing a stunt kite is very limited! However, experience or no experience, it's a fact that Delta stunt kites depend heavily on being symmetrical, just like single-liners. The left side should be an exact mirror-image of the right side, in other words.

I would rig the kite indoors, then very carefully look at the sail and the bridle lines on either side. Get out a ruler or tape measure...

Sail: Any obvious stretching, letting the sail billow a little more on one side? Are the positions and lengths of any stand-offs exactly the same on both sides? Where the sail edges attach to the spars, does this look exactly the same on both sides? Any slippage on just one side? Does anything look different on the left as compared to the right? Perhaps it could be fixed when those seams are re-sewn.

Bridle: Measure the lengths of every individual leg of the bridle lines. The measurements on one side of the kite should correspond exactly with the measurements on the other. If anything differs by a measurable amount, double-check, then try to adjust it back to symmetry with the other side.

Spars: Look right along them - are they all perfectly straight? If not, replacing the spars should help. What are they made of? If plastic or fiber-glass, that's OK, but wooden ones... One leading-edge dowel might be more flexible than the other one, which would certainly affect turning ability in one direction. But I doubt you have a dowel kite :-)

I realize my reply is heavy on fault-finding and a bit light on what to actually do about fixing the fault, but I hope this is helpful anyway! If you can pin-point the difference between the left and right sides, perhaps someone at a local kite shop might be able to go the rest of the way in suggesting the best fix.

Happy fault finding!

Thanks for the help! I'll piddle with it and see what happens and hopefully my son can enjoy it as much as I have.

Step Two

Hi Adam, Lets go with...

STEP ONE: Tim has excellent tips so try them first. Stunt kite performance is highly dependent on the Symmetrics of the kite and the bridle settings. But let's say you take all the steps Tim suggests and it still turns slow to the left.

STEP TWO: Take a very small d-ring, I find them at WalMart in the camping accessories department. Take the d-ring and attatch it to the left bridle in various locations by simply wrapping the string onto it about three times around then clip the kite line to the d-ring. Fly the kite several times changing the location of the d-ring after each fight.

What you are looking for is the SWEET-SPOT. Once the kite performs correctly mark the spot with a magic marker, take the d-ring off and adjust the bridle line so that your kite line attaches at that point. Sometimes an old kite has a built in bad habit. What you're doing here is simply adjusting one side to correct it.

    Tetra Takes Off

    It's been a bit of an uphill battle getting a decent flight out of the heavy, crudely put-together 10-cell tetra... Earlier today the breeze was great but misty rain persisted for hours on end. Finall…
