I've often wondered why my MKIV yaw string behaves properly on my Stemme
when the engine is running.Â* Does the programming generate a feedback
signal opposite in phase and equal to the amplitude of the propeller
pulses?Â* How is the propeller pulse signal captured by the MKIV system?Â*
Does it read the alpha particle emissions of the proprietary yarn used
in the construction of the device?Â* What is the half life of the yarn?Â*
Etc...

I posted before re Wings and Wheels' acquisition of the MKIV and Quiet Vent.

Some inside info:

Sean visited beautiful Minden, NV for training and to pick up manufacturing tools and fixtures. About half way through training, he was a little slow and being every bit as picky as me, rejecting about half. He says, "There is a lot to this!". I respond, "And such a little thing, the customer would never know." I was pleased at how fast he was catching on.

Several weeks later I call to see how things were going. Maybe sold, but the MKIV is still my baby. Sean assures me all is well, says he's changed the packaging and will send me a sample. When it arrives I see it's excellent quality, and packaging is nicer too.

Still you may have concerns, So if you purchase a MKIV or QV from W & W, and feel you didn't get your money's worth for whatever reason, just contact me and I'll refund your money up to the full purchase price, including shipping. Please note this is a limited time offer.

Okay, time's up!

Good Soaring!

Bumper you should outsource this to China. They will make them for $0.20, 200,000 to a container. The instructions may be a little funky and the cardboard packaging limp, but who cares if it points the wrong way?

Then get the Trump administration to give you $1,000,000 in tax incentives to bring manufacturing back. Modern Business 101.
I thought about that, but then remembered how much I worried when my last glider came across the North Atlantic. Those shipping containers go overboard sometimes. From 2008 to 2013, 1679 containers were lost per year. With my luck, and your well meaning help, one of those would have had 200,000 MKIV's on it. Can you imagine what would happen to soaring as we know it without the MKIV?

Besides, each MKIV requires extensive programming and hands on training to insure it points the right way and doesn't wag it's tail too much - like my golden retriever, "Thumper" they tend to get excited, especially when you fly right. I just checked and none of the world's truly accomplished yaw string programmers speak Chinese or Chinglish. So I guess I'm out that million $$.
