The MKIV is clearly the pinnacle of yaw string technology. Meticulously crafted, it looks great on my glider. However, it suffers from the same problem I have noticed on all yaw strings I have flown. In flight, it constantly swings off the centerline 10, 20, sometimes even 30 degrees, particularly while thermalling. What’s up with that?

Mike-Mike,

Each MKIV "high tech" yaw string leaves our shop eager to learn, but obviously young and impressionable - - they do have a tendancy towards having a short attention span and will often display a wild tendancy to go whichever way the wind blows.

After installation, especially during early training it's important to treat your young MKIV gently, they are sensitive. Never sweat at it, unless it's obviously heading entirely the wrong way. It's okay to firmly tell it to "straighten up and fly right".

We are working on providing better pre-shipment training on our end. Until then, if you have a really bad one, you can tape the end down straight before flight to show it what you expect of it. Don't do this often though as you risk breaking it's spirit. Not good.

all the best,
