Don't know if zig-zag works on the LS-3, anybody got
performance feedback on that?

Sorry for the late response; just getting caught up after a long trip.

My experience with turbulator tape on my LS-3 back in the mid 80s was
favorable. Testing against XX's Ventus seemed to indicate improvement.
I tried several locations before finding one that worked (no, I don't
recall what the % of chord was). This was pre-mylar, with tape as the
external seal on the flaperon plus the internal teflon-coated fabric
seal.
