MKIII yaw string sale

Like the Spitfire of WWII fame that inspired it's name, the "high tech" yaw
string improves again, with the MKIV replacing the MKIII. Front line units
are already being equipped with the IV.

Normally I throw away old stock if I've made an improvement, and start
selling the new, better one right away (probably not smart from a P/L
perspective). This time I've decided to sell the limited number of MKIII's
remaining at clearance price of $6 USD, 40% off the regular price of $10.
Contact me by email for availability - - first come etc.

The new MKIV's clear base looks almost identical to the MKIII it replaces.
The base is now made from a softer plastic to better conform to the canopy
curve. The base also has a thermoformed yarn channel that, along with the
new plastics better adhesion properties, should eliminate the cosmetic
problem of bubbles sometimes forming in the base laminate.

The new MKIV base required different tooling and assembly processes, and is
more tedious to assemble . . . still, price remains $10 USD (includes
domestic shipping). Available in natural wool (red, royal blue, light blue,
yellow) or synthetic yarn (previous colors plus white and turquoise).

Yo Bump,

Are they PMA'd, STC'd or TSO'd? Because my local IA/FAA FSDO/CFI says
I can't install it unless it has the Good Gliderkeeping Seal of
Approval! What about dampening, I hate it when it vibrates back and
forth at 150hZ at the lower speeds.

;-)

Not TSO'd, PMA'd, or STC'd. They are, however, J.C.Whitney, NAPA, and
McMaster-Carr approved, which is just as good, maybe better (Orville and
Wilbur didn't give a rat's _ _ _ about acronym groups). But, the MKIV does
come with the coveted Sham-Wow, Slap-Chop, Energy Star seal of approval

Damping is excellent at tested speeds below .21 Mach. Much above that, the
pilot may have other issues with which to concern himself, rather than his
nice looking yaw string.

Sorry I don't have any pictures of the new MKIV yet, however they look
almost identical to the MKIII.

Great. Just great. Planned obsolescence. Clearly, this is just
another ploy by Bumper to get rich on the backs of poor glider folk.
When will it all end?

Tim,

"We reserve the right to make product improvements and/or change prices at
any time".

But, we also care deeply about customer satisfaction. If you return your
MKIII in new condition, it will be cheerfully replaced with a brand new
shiny MKIV that doesn't smell like old sheep . . . and all at no cost.

Note: I don't hate sheep . . . I live in NV where the sheep look sheepish
and the sheepher . . . er, we won't go there.
