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.



My understanding is that clear yaw string tape can only be safely used with clear yaw strings

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)

Unfortunately, the dealer network is very thin. Just try getting your
string serviced in Washington State!

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
fully developed and requires more engineering. I'm thinking of a remote
control for calibration of the device. The constant pointing to one side
or the other is quite unacceptable.

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.

'calibration is vastly over-rated! Starch, on the other hand.....

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.

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.

Does anyone know who still supplies these canopy holes?

As the maker of fine glider assembly tools, I'm sure we at http://www.z5mfg.com/ can supply you with what ever hole you need.
