Apparently this is an Eric(k) only thread :-)

The new manuals show very precise what needs to go where.

Hi Eric,

Couple of thoughts. First, the best place to discuss LS-specific topics
(s=

As far as your specific question, I've done LS4's both ways. The
maintena=

A couple questions.

I had ailerons removed for refinishing and now looking at maintenance

I could have sworn though that the gap seal was installed more like the
r=

I didn't see anything in glider log book about the gap seal being

=20
Would it be OK to use the adhesive gap seal tape? And if so what
width?=
=20
=20
The advantage would be the ailerons can be put back on by A/P and I can

With the double sided adhesive/non-adhesive gap seal tape I would have

Also does anyone know the proper width of the mylar seal? The former

Thanks
