Wind and weather has taken it's toll on the wind sock at our field. Has any one an idea where we could buy a wind sock of suitable size ( 15 to 20 MPH) sock to replace ours?

I use a yellow ribbon, it is super sensitive & super cheap.

I've got this one, and I love it.

I take it out to the soccer fields with me when I fly -- it helps "stake my territory", and keeps the soccer people away.

I like the one at Hodges Hobbies...

I asked Mac about that windsock last summer -- it is an actual airplane that he actually flew!

Indeed it is. And the balance of it is awesome. Just a hint of a breeze and the prop turns and it noses into the wind, I find amazing how little wind it takes to affect it.

The info you gave me was exactly what I was looking for. Thanks so much. I'm taking the info to our monthly meeting tonight.

DIY Windsock. Very cheap.

DIY Windguages to calibrate windsock in need:
1. How to use your Balancer as a wind speed indicator (Anemometer)
A very unique feature of a Precision Balancer is its ability to read wind speed.
This method can be as accurate as 2mph.
All you need is a Tachometer and a Balancer and an 11x8 Prop.
Place the prop on the balancer and either place the balancer on a level surfaced or hold it so that the BACK of the prop is facing the direction the wind is coming from.
Turn on the tach and read the wind speed. The wind speed with the 11x8 prop will be the RPM divided by 100. Most tachometers read rpm in thousands so the wind speed will be in tens. For example, a reading of 0.5 on the tach is 5 mph. A reading of 18.8 on the tach is 188 mph (in which case you should not fly).
The recommended prop for most accurate readings is a Top Flite 11x8 Power Point prop. Any 11x8 prop should work and be reasonably accurate, if you want to be more accurate use the following formula:-
Wind Speed (in MPH) = RPM X Pitch of the prop (in inches) X .00114

Wind Gauge

DIY wind gauge!
Drawings attached - print them, and fix it to a piece of stiff card.
The Beaufort Scale is on one side, and speeds in mph and kph on the other side.
Fix this to a 6ft x 1" x 1" wooden pole (Or broom handle with extension)
- insert pin at centre of scale, attach a thread at least 12" long (not critical) with a pin-pong ball at the end. The wind speed can be read off from the scales.
