Re: LS-4A Turbulator tape question

[Joe Lacour]

I'm sanding on my LS-4A wings and was wondering several things.
Does properly placed ZZ Tape noticeably reduce the high speed drag of
an LS-4A? Probably does.
Does anyone know the proper location of ZZ Tape on the wings?

If it is in the right spot and works, I'll sand around it. If it is
not in the correct location, I'll remove and replace it. And if it is
reported to have little effect, I'll leave it off.

I'm intrigued by the number of people asking about ZZ tape for gliders
whose airfoils weren't designed for it, and the numerous times Dick
Johnson has reported that gliders with airfoils designed for ZZ tape
do better without it.
