Dave,
I recommend using mylar on all control surfaces and have added it to
the LS-3/4/6/7/8 without a problem. I sand the inside of the mylar
where the stickie will go with 220 and do the same to the horizontal
(just the 10mm area), then wipe both down with acetone before laying
down the stickie and mylar. Next, roll it down with considerable
pressure to insure a good bond, followed by the transition tape over
the leading edge of the mylar. Some have had mylar come loose because
they didn't do the above and or didn't remove all wax from the
affected area. Treat this with the respect it deserves, or take it to
a glider repair shop. We have had a bail-out caused by lifting mylar
on the stab.

Hey guys, what's your opinion on the use of mylar seals at the
horizontal stab/elevator gap? Specifically for LS ships. Do people opt
not to use them for fear of "lifting" tape or mylar and causing
elevator effectiveness issues? Losing elevator effectiveness is
certainly a valid concern, but does it warrant not using mylar seals
there altogether?

Thanks,

Here's the text from the flight manual for my ship (LS1f): "Taping of
upper aileron and elevator gaps, as well as the fuselage wing
connection, is necessary for rudder effectiveness and performance."

How do you interpret that? Are they recommending the equivalent of
mylar seals? Only on the top?
