Title: Does your kite whistle??
Post by: iwannafly on August 02, 2009, 06:46 PM
I was able to get out for the second time with my brand new dual line kite.;D The wind was fairly smooth and at times very strong. I have a PRISM QUANTUM. When the wind was strong or the kite was moving fast, I could hear a rather loud whistle. I think it was coming from the lines. I'm not sure because the line I used for my kite's maiden voyage were borrowed and the wind was not that strong. Has anyone ever had this happen to them? Is this normal in high winds? Is it the kite or the lines? And if it is the kite should I give it the name "SCREAMING MEANY"?

It's the lines.   :D

That's usually when I switch to a vented kite or to a heavier set of lines.

I also fly a Quantum and when the winds are stronger the lines whistle as well the sail. But, believe me the kite can take it. I love my Quantum it is a great kite to learn on. It does the basic kite skills as well as many of the tricks. It handles pulling a tail which is what I love to do. Nothing better then flying on the beach with a long tail flowing behind the kite.

I know that my QPro's whistle, at least if you have the yo-yo stoppers in place. Being that they are recycled stand off fittings, and thus are hollow...

I find it particularly noticeable on the SUL as it passes.

Tramontanas had the spine in FRONT of the sail inside of a sleeve which ran from the nose to the keel. Under the right wind conditions, the sleeve would whistle.

I'm including a picture of the back of a Tram and you will not see the spine where it would normally be on a dualie.

You may notice the pitch changes the more wraps you have in your lines.

I've had lines shrieking with our Quantum and whatever the stock lines are. It was pulling pretty hard at the time. Definitely over 15MPH.

I have always liked the whistling or buzzing of the kite. It is useful when people walk into the kite window. I just fly a hard and fast pass about 4 meters over their heads and then go to the top of the window and wait for them to notice that they are in a dangerous area.

I find that most people respond in a positive way to this action.

Thanks for the replies.

Yes, the wind was really strong.

I was using the stock lines - 85', 150#.

And I don't think at my current level of skill it would be a good idea to buzz anyone in my flight zone. Unless of course they are wearing a helmet. ;)

Next time the wind is up I'll try to see if it changes pitch with the lines twisted up. I'll turn it into a science lesson for my daughter. Or would that be a music lesson? :-\

Music for sure....
If the lines are whistling sometimes I play with the lines rather than the kite. By this I mean manipulate the kite of course but in a way that the lines change pitch sonically and rhythmically. Sometimes this may be simply letting the kite "glide" with pump and release motions...tightening/loosening the line or "string" in this case, creating cool tones and drones.

We were out flying the NSR the other day, couldn't hear the lines whistle at all.  I guess the NSR is the only one I own that doesn't make the lines whistle....

You wern't flying in high enough winds Kent.  ;)
Back home they screamed, including the NSR.

I think it's mostly good quality Spectra lines that whistle. If you used cheaper lines, like braided polyester or maybe even Spectra "Sport" (Poly-spectra blend), I'm not sure you'd hear it. I think it's the tiny diameter of the Spectra that so excites the air. Not sure where I heard or read or learned this. It's even possible that (gasp!) it's wrong!

If you want whistling lines, fly on the lightest weight lines you feel won't break. If you pull with a given tension on different weight lines, the lightest lines will vibrate at the highest frequency, which are easiest for our ears to hear.

All kite lines vibrate when tensioned, but the lower frequencies need more power to be audible. That's why you hear people talk about 15" woofers. No one talks about 15" tweeters.  ???

By the way, the lines will be loudest right before they break.  :(

Back in the day, our 200# Kevlar lines screamed in a 20 mph wind while flying a Hawaiian.
It's not just "cheap lines" or Spectra that make noise. They all make noise in high enough winds.

Guess I shoulda used some smilies in my earlier post.  I agree, all lines vibrate, just on the NSR you really can't hear them much over the noise of the kite (which was my poor attempt at a little humor in the earlier post). :) :) :) :) :)

I doubt you could hear the lines on a Wasp either. :) :) :) <-smilies and another poor attempts at humor.
