Clear Yaw string tape?

[Bruno]

I have seen a few gliders that had yaw strings attached with something
other than the white tape most of us use. It was either a clear tape
or clear sticker. If any of you use something other than the white
tape to attach your yaw string please share what you use. Thanks!

Scotch clear packing tape. Cut it into a little triangle (for style
points), stick the yarn on (I prefer green - with a knot at both ends),
and carefully place dead center on canopy, as far back as you can
stand.

Doesn't shrink or leave much residue like white tape. And you can
kinda see through it...

I also it to cover the big horizontal tail attachment opening on my LS6
- one piece fits perfectly.

I have seen a glider that had a very small, round hole
for the yaw string drilled in the canopy. The owner
tied knots inside and out, tighly against the hole.

That was probably 35 years ago and I don't remember
what or who. I would not recommend it.

Kinda suck when, after your buddies ask why you fly slow and sideways,
you realize you drilled 1 cm to starboard.

I saw one stuck on with a drop of clear RTV (silicone rubber). When I
asked about it, the owner said it stuck up into the airflow a bit
better and was a little more responsive. He also commented that he
didn't fix his gaze on it nearly so often as the little triangle of
white tape that he used in the past. I think I'll try that soon, unless
someone tells me that the RTV will damage my plexiglass.

Best thing I've found is a special clear tape by 3M used to protect the
leading edges of props. In AZ we use 6" wide lengths of this tape to
shield the undersides of our booms from the glass-eating gravel we land
on. It works great for yaw string attachment -- easy to remove but
doesn't remove itself, leaves no residue, very clear. E-mail me your
snail mail address if you'd like a sample (tuno(at)pobox(dot)com).

If you don't know how to find the centerline, I certainly
don't recommend it!

Bear 3M make a an outstanding clear flexible tape currently retailed
as "clear all weather" tape. Comes in a roll approx 2" in width.

A lot dearer than and has a different texture from packaging tape. It
is backed with a strong adhesive which remains with the tape when you
pull the old tape off, and is highly resistant to lifting due weather
or exposure. Once you put it on, it stays there until you deside to
take it off. Good stuff. Highly recommended.

Hi,

I sell clear (or at least translucent) "wing tape" here:
http://www.cumulus-soaring.com/mmm.htm

It is a 3M product and I like it a lot. I have never used it to hold a yaw
string on, but I imagine it would work. It is mainly purchased by owners of
gliders that are colors other than white for use as wing gap seal tape.

Good Soaring,

My partners and I used to keep our yaw string suspended about 3/4"
above the surface on a piece of wire bent to shape and taped into
place. It gave a little better precision by keeping the string out of
the canopy's boundary layer, which was prone to a bit of hysteresis.
However, we eventually decided it wasn't enough of an improvement to
offset the pain in the butt of removing it every time we put the
canopy cover on, so we gave it up.

Just be sure you use *metric* yaw string on a German ship.

Though I haven't really advertised it, a number of years back I invented the
MKII "high tech" yaw string. The high tech part being somewhat
tongue-in-cheek, though generally unreliable and refutable sources indicate
the MKII will add at least 2 points to your L/D - - and even if not, it
still looks a whole lot better than tape! I've sold 70 - 100 MKII's, mostly
to other Stemme owners and a few on the ramp at Minden . . . so perhaps
someone will post their opinion.

The MKII consists of a clear turbulator base w/ clear adhesive. Yarn is
natural wool, as that's reputed to be kinder to the Plexi than synthetic
yarn that scratches. The yarn exits through a small hole in the plastic
base. Included is an index dot for the inside of the canopy, instructions
and a money back guarantee if you're not happy.

Several MKII's were placed on a test strip of Plexiglas and continuously
exposed for over two years in the California sun. After the exposure test,
the base and adhesive could still be easily removed with no damage or
residue. To order, send $9 USD and a self-addressed, stamped envelope to:

John Morgan
194 Taylor Creek Rd.
Minden, NV 89460

I also should have a "quiet vent" kit (QV) available soon. Added to the
standard swing out vent in the canopy sliding window, testing shows a noise
reduction of 10 db - - it quiets the vent to a pleasant, low level. I'm
still working to resolve some issues with a few QV failures while wave
flying, if the QV is mechanically stressed while exposed to sub-zero
temperatures. If you don't "pluck" at the QV while it's super cold, it works
fine as is. When ready for "market", it will be $5 US.

all the best,

I've always felt (but have no evidence) that positioning a yaw string on
the canopy is not optimal, and that you really want it in clean,
undisturbed, air (yeah, like the 2-33). There could be 2 problems with
the canopy mount. One, it is flush with a compound curve surface and who
knows that the air is doing there. Two, it is in the boundary layer
between the canopy surface and the airflow and who knows that the air is
doing there.

I wonder if any one has experimented with a "normally" mounted yaw
string and one placed on a post several cm higher.

Tony V.

[Bill Daniels]

Yep, done that. The string on the canopy surface is about twice as
sensitive to yaw angles as the one on a one inch tall post. In other words,
the string on the canopy surface 'over-indicates' by about 2:1. I think
that's a good thing.

As another poster noted, getting the string placed exactly on the centerline
is the key. I've found that tailors cloth measuring tape is useful for
making those measurements since it won't scratch the canopy.

Despite the aversion expressed to drilling a hole for the yaw string, that
approach has some advantages.
1. It is a very 'clean' attachment with no tape blocking the pilots forward
view.
2. If the measurements are made precisely before the hole is drilled, the
positioning will always be exact.
3. The string is easily removed/replaced for cleaning and polishing the
canopy.
4. There is NO chance of the string blowing off in flight.

Note: If you decide to drill, you MUST use a sharp new drill made
specifically for drilling plastic.

Our club gliders all had or still have the yaw string mounted some centimetres
off the fuselage.
The Blanik L13 has its on a TE probe about 5cm long, the two BergFalkes have
wire standoffs on the nose. In all cases the string in the free stream tends to
flap like a flag, which can be a little irritating. They also easily drape
around the support and inattentive pilots then end up flying with no yaw
indication. We recently moved the string to the canopy on one of the Bergies,
and the result is an improvement.

In my experience the canopy mounted string is a stabler, and in most situations
better, tool. The small area occluded by the attachment is not significant as
long as you do move your head when scanning. Otherwise it can obscure other
aircraft.

There used to be a burble round the canopy on my sailplane,
which meant there was only a narrow speed range where the yaw string was
anything like stable.

I wanted to update the TE system from a diaphragm type to a
Braunsweig tube. It occurred to me that if I put the tube immediately
ahead of the canopy I could kill two birds with one stone. Worked a
treat!

I thought maybe I could use the tube as a radio antenna, too, (3
birds?) but never got around to trying it.

I'm not so sure...there seems to be a definite hysteresis effect in
the boundary layer. I've experimented with two strings, one on a 3/4"
post and one at its base, and they did NOT respond in sync. I found I
could deflect one left, the other right, and hold it that way for a
second or two.

Better, I think, to poke it with a hot piece of wire to avoid
stress-raising tool marks. Push from the outside in and pull the wire
on through from the inside...that way you don't get a raised lip on
the outside. It works well for stopping cracks, too.

Try a Donut Shop that sells donut holes; they will

A bit off topic but...
Years ago I had been told about a Florida company that put holes in
sheet metal. It seems that after years of being in business, they had
quite an inventory of improperly sized holes that they had not been
able to install in the sheet metal. They had to get rid of them, so
they flushed them down the storm drain. And, of course, they collected
in the groundwater, in bunches. After some time, they displaced enough
limestone that those giant sinkholes formed and the ground collapsed
where the bad holes had collected.

Just passing it along. Hope it helps.

Personally, I just WON'T use anything other than Bumper's setup. The money is trivial, and it doesn't UGLY UP your glider. Speaking of which, I need to order some ASAP for gifts.
The white tape, duct tape, or any other tape option will ALWAYS leave residue that always look like crap.
Off my soapbox now.

BTW, Other things on my 'acquisition' list: the wide graphic of a nose-on glider that looks so nice on the back of the truck. The XCSoar graphic that one might put ON the glider.
If I can arrange to get this stuff with a phone call, that's good, because anything requiring much more than talking seems to be slipping beyond my capability. emailing me directly to somehow set up a clandestine phone conversation might work. , or the ever-so-imaginative will work.

Uncle Fuzzy,

SoaringNV (775 782-9595) has really nice glider decals for sale. Not sure if they'll ship, but worth checking. They've been closed for the last few days while they finish burning California and quit sending us all the smoke.

Thank you for the ringing endorsement of the MKIV "high tech" Yaw String!

It's available from Cumulus Soaring, SoaringNV, and Williams Soaring Center, and from me direct.

I have had very satisfactory service from my MK3 and MK4 yaw strings.
Nice clear adhesive patch that can be removed from the canopy without leaving a mark. Very satisfying triangular shape to the adhesive patch gives me a very warm feeling inside whenever I examine it during flight.

Also, very excellent customer service. One time at Minden I was having some questions about the length and responsiveness of the fibrous indicating structure and the company representative drove up to my plane and addressed my concerns in less than one hour from the telephone call.

There are just a couple products that I totally ENDORSE with no reservations. Fortunately none are hard to find.
1. 3M 'General Adhesive Cleaner.
Available anywhere automotive finishing supplies are sold, and some of the better auto parts stores: Wings and Wheels has a picture.
When I bought my Speed Astir, it took me nearly 20 hours of cleaning to remove the many hears of tape residue.
The next thing is the tape itself - Bowlus Super Tape. Again, Cumulus soaringing. I really have tried almost every other tape out there, and the Bowlus tape doesn't creep as badly as any of the others. It will USUALLY make it through a weekend in place, even though the temps here in southern Nevada are somewhat extreme.
Wings and Wheels also sells the heavy white clothe tape for those Grob on e sideded hinge lines. Last (ugly, but functional) an entire season. I DON'T recommend 'Blenderm' clearish medical tape, only because the adhesisive residue is somewhat difficult to deal with. Lots of guys DO like it for gear doors, etc. I've also been known to use Mono-kote 'trim tape, to cover large-ish holes like ballast dump areas. Again, the adheasive residue is kind of a lot of work to get off.
Bumper's Mk (whatever) yaw string.

Unfortunately, the dealer network is very thin. Just try getting your

There is a good chance that using RTV for attaching a yaw string could lead to a permanent mark on the canopy. Most of the RTV's have Acetic acid and formaldehyde and a list of other chemicals that may leave a blemish. I would not recommend using it. Acetic Acid is a component of Acrylic adhesive BTW.

QT,

You will be pleased to learn that the new MKIV.1a "high tech", "clearly invisible", imaginary yaw string is in stock, on sale at 50% off, and ready for immediate non-shipment. Just clean a spot for it on your canopy, send payment, and enjoy! :c)

Eric,

Quit complaining and move to Nevada. Besides superb soaring conditions, you can get your string serviced in less than an hour. Also, being Nevada, I hear you can get almost anything else serviced too . . . though I wouldn't know about that.

Yeah, well I have serious reservations. I just don't think it's quite

Well, Tony, I don't know what to say. I'll admit that some earlier MK's inadvertently were shipped with an open loop feedback system. And some did not receive proper training before being sent to meet "their glider". This was quickly rectified in production and all new MKIV's come with extensive primary* training and a closed loop system that cleverly monitors relative wind and also accepts inputs from all flight control surfaces with a rather strong rudder bias. This insures that the MKIV will always point in a direction while in flight.

Some manufacturers might not admit it, but since we have a transparent operation here, in the interest of full disclosure we have uncovered a bug in our software and are working on a patch or exorcism or something. Only seen this on strong thermal days at Minden, some MKIV's will inexplicably act possessed, spinning rapidly and often pointing straight up. We think they are being affected by karma or force fields from the airport wind sock, which purportedly is also pointing straight up and twisting rapidly during such times. For all we know, it could be possessed as well. There is little risk to pilots as most are well clear, circling at cloud base during these troubling moments.

*Advanced training is the owner's responsibility. Repetitive training works best, with frequent flights being an excellent way to insure your MKIV doesn't go stupid and forget how it's supposed to behave.

I'd jump on this is a heartbeat except for all the comments I would have to endure about the king's new yawstring...

I love that this re-surfaces from time-to time. It always takes me back my first walk down the fie-down area at Jean. Marveling at the highly polished, beautiful and sleek white curvaceous German girls.
.....and having the ride 'spoiled' by seeing a big ugly splotch of old tape residue on each and every one. ugh. Some time (months? ) David, Paul, and Krys partnered up and bought a Discus, and it came with a Mark (whatever) yaw string (and probably also the QV) and I knew that I would NEVER use anything else.
RAS - my 'solution' to the chemo insomnia on top of my 'normal' insomnia.

U. Fuz',

That was a chuckle! My thoughts exactly.

First MK(?) (and there were several prototypes of varying complexity) was a direct result of my thinking how out of place it looked to have a taped on yaw string on my Stemme. The MK series has evolved with lots of improvements to the point I'm happy with the "IV", and I'm the type who suffers the frustrating affliction of not being content if there's a way I can improve something.

Of all the tape residue I've had to remove, the very worst has been from clear tape, "Scotch", packing tape, whatever. UV degrades the clear plastic so it has no mechanical strength that would allow it to be pulled off. Rather it fractures like the clay on a dry lake bed, each little bit clinging tenaciously to the rock hard, dried out adhesive beneath . . . and little bit "protecting" the underlying adhesive from being softened by whatever solvent* one is brave enough to use on Plexi. *Denatured alcohol is a strong as I've used, and even that should be used with caution.

MKIV's and Quiet Vents both use 3M VHB (very high bond) clear acrylic tape. Even after extended exposure it remains easy to remove.
