Thanks Al. I made my own vg's and have no "instructions" so wasn't sure if
that was the best spot but figured someone must have figured it was. I will
put mine there too.
Thanks again everyone.

I was told to put them there by Jerry at PNW Aero. I didn't ask why but
they did solve the lack of elevator authority at stall.

I was just wondering if someone's VG instructions were to place them there
or if one guys saw it and just copied it. I would think the tail (airfoil)
would have the same lift characteristics as any other?

I'm no aerodynamicist, but my guess is that is the critical spot where the
boundary layer needs to be energized, whereas on the wing the critical lift
area is near the front?????
Anybody know the engineering behind the placement?

Why do most guys put the stab/elevator VG's back at the hinge line (on the
bottom of stab of course) and not more forward like on the wing? Is there
some guidance on this? It seems to me it would be like putting the wing
vg's back just in front of the flaps or aileron hinge? Trying to decide
where to put them.
Thanks,

I installed the homemade vg's on the bottom of the stab. Thought I would
try and see if Matt's picture enclosure is working. You can only see 5 pairs
in the picture (if the picture comes through) but I have 8 on each side.
The inboard ones had to move forward a little more.
