As I don't have a gadget for telling me the wind speed, I was wondering if there are any tricks to judging this. My LPG 85' lines started whistling when I was flying in the gusty winds yesterday. What wind speed does this normally occur at? Or am I the only flier with musical lines! :lol:

I don't know if this will help you or not, but there is always the trusty Beaufort Wind Scale:

It is hard to tell wind speed by the sound of the lines. The angle of the attack etc.

I know this wasn't what you asked for but this little anemometer has been great and the price is right. http://www.amazon.co...r/dp/B0002WZRKE I did find one on ebay in England http://cgi.ebay.co.u...id=p3286.c0.m14

Hope that is helpfu.

The fuzz on my ears is pretty reliable for guessing wind speed, seems to be getting more accurate as I age. :)

I was impressed when you could tell that a butterfly had flown by the other day on the line.

I felt a ripple in the wind force. :D

Seriously, Beaufort is the best measure without gadgets, second only to experience. ;)

One of our club members has come to kiting from rc planes. He told me the orange windsocks you see at airfields are calibrated to be fully horizontal at 15mph+. (helps pilots landing in crosswinds) Shoudln't be beyond the wit of a kite sewer to make a set of socks to sit on pole(s) calibrated to 2, 5, 10 , 15 , 20 mph etc. It's already on my (long) project list.

It's easy in the uk this summer though, either 30+ or nothing.

Trick will be to make sure they're high enough, and out of the near-ground wind chop. :)

Also, might be ideal to spread 2-4 of them around your field, different wind sometimes, depending on obstructions.

Nifty idea, for sure.

Boomerangers not only have issue with wind speed but also wind directions. They are usually seen picking a couple of fingers full of grass and letting it fall from their hand. However in recent years it is not uncommon to see quarter inch dowels with a streamer attached to the top to aid with wind direction and wind speed.
We could always us an extra spar with a small ribbon of sail cloth and have it calibrated to a windmeter.

I'm a sailor and can usually guess the wind within 2 - 3 knots, errr MPH. I also carry a windmeter.
