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,

Tape that bothersome loose end down. Why didn’t I think of that! Thanks, Bumper. In addition to great products, your customer support is unequalled. I also appreciate learning it’s okay to tell the MKIV to “straighten up and fly right”. Silly me. I thought that’s what it was telling me. Anyway, with that cleared up, now I can concentrate on why my flights are always so much slower that everybody else’s.

Seriously now, any tips on how to fly without a yaw string should our beloved MKIV high tech devise fail?

Hmmm... Assuming this is a serious question, in the days before even the MKI
was available, I experienced total yaw string failure. More than once,
actually, on ships ranging from 1-26 (captured by canopy rail) to 15-meter
glass (adhesive failure...and the tape was hardly even 10 years old!).

Being a cheap (rhymes with "dastard"), I continued soaring, coordinating by
feel and sound. Easy if you have a noisy ship. (Sorry if this costs you future
sales, Bumper!)

No, that rhymes with "bustard":

The bustard's an exquisite fowl
With almost no reason to howl.
It escapes what would be
Illigitimacy
By the grace of a fortunate vowel.

After a critical failure, such as a premature yaw string departure, the safe choice would, of course, be to bail out. There will always be the "hero" types that will ride her down I suppose, but consider the risks involved. You might be in a deadly tail spin and not even know it.

Clearly prevention is the best policy. To help reduce the chance of yaw string departure, each MKIV base yarn is injected with a clear polymer adhesive as a final assembly step. This to help prevent the unpleasant "early pull out" failure.

Your right, if I can't fly this thing straight I'm gettin' the hell out....-/

In the past my yaw strings were made of everything from boars hair to alfalfa stalks and held onto the can-o-pee with rivets and bailing wire. Now having flown with the Bumper MKminus3 on up to the MKIV I have since never landed out, have earned a quadruple diamond with gold oak leaf clusters and have used my glider for a Flight-For-Life mission (which, let me tell you, was a little crowded with the stretcher on board). Zounds! What an advance for mankind! Is there a Nobel prize for glider particle astrophysics?

What are the possibilities of a tour of the factory? I'd be intreeged to see the manufacturing process.
