MKIV "high tech" yaw string (tech note)

Hey! I just installed a MK-4 on my LAK-17a and it seems to fly
straighter than before. Do you think I made that same double tape mistake?

I also installed Bumper's quiet vent mod and am very pleased with the
smoother, quieter air coming in the vent.

Beat this, I heard of a pilot (!) who drilled a hole in the canopy for the
yaw string!

Doh..

So wait, were do I download the firmware update for the yaw string?

And do the yearly firmware updates make it incompatible with the old firmware on another MKIV, say, over the canopy for the back seater? Or on your flying buddies plane?

Global climate change, winter is here already.

Why that's proprietary, updates and calibration are done in a lead lined clean room at the factory - $15 includes return shipping. But for about the same sum you can have the very latest firmware along with all brand new hardware from most of the better on-line glider accessory suppliers.

Or, you could drill a hole in the canopy . . .

Should the drilled hole be round or square? I'd think a square hole would have
less drag if one assumes equal hole widths and perfect sailplane alignment
with the oncoming air. Geez, for $15, is it unreasonable to expect decent
customer service, like some directions for drilling the preferred square hole?
Is it winter yet?

Bob - I'll shut up now - W.

Laugh all you want. The square hole allows me to retract the Yaw String during high speed flight, resulting in significant drag reduction. I hear that the Mark V Yaw String includes "Speed Sense"TM Technology out of the box for this very purpose. At least, that's what I heard from a guy who knows a guys who....

I simply installed mine on the inside of the canopy, this offered the
best drag reduction possible. It also works as a rudimentary turn and
bank indicator - shh, don't tell the C/D or the R/C...

Everyone needs to remember to use special bits when drilling through their plexi. http://www.eplastics.com/plexiglass_...tic_drill_bits
