Hey Bumper.
When are you releasing the ultra low drag version of your yaw string?

This ULD MKV project has been a closely guarded secret, so I'm curious how you found out about this. Very frustrating to have this leaked prior to our planned April 1st release date. We don't want the superlative MKV negatively impacting sales of the excellent MKIV's in stock at our dealers.

But that you've let out, here's a few details. Unlike the MKIV base that is about .038" thick to keep the yarn off the canopy, the MKV is only .005" thick. The "old" MKIV is installed on the outer surface of the canopy and is thus subject to all the vagaries of relative wind flow, turbulence, stalls, spins, falling out of the sky should you run out of wind, and of course the dreaded tail-spin.

The MKV is completely different and of epochal significance. Yes, people will refer to sailplanes as "pre and post MKV" it is that monumental a change in yaw string technology. The MKV installs inside the canopy so there's no additional drag whatsoever!

So, how did we do it? While some of the details of the new MKV are closely held trade secrets (hopefully more so than our leaked release date), I can share with you that the MKV will be available in three distinct models and several color options. The models are "Left", "Right", and we expect to be the most popular, "Center" version. In the interest of forthrightness, each model is really exactly the same except for packaging, price, and the angle of dangle in the installation instructions. We will be charging a premium for the Center model due to expected higher demand.

Installation is simple, even a non-pilot could do it after several beers. Peel your new MKV decal off backing paper and apply to inside surface of canopy, paying close attention to suggested installation angle. The MKV is guaranteed to be stable in all modes of flight.

Deciding which model is right for you is easy. If your have a heavy left foot, get the "Left" version and things will seem right (or left) most of the time. Heavy right footer should order the Right version. Helpful Hint: install all three and most always one of the MKV's will be close to spot on.

You may wish to order an old MKIV while they are still available. My guess is they are destined to become a collector's item, just as the pellet vario was made obsolete by the Electronic Pellet Vario.
