For me a higher stall speed is going in the wrong direction

This is consistent with some limited VG experiments Len made on my airplane.
In other words, you still have limited to no aileron authority at the stall.
Len did do some experiments that resulted better characteristics at the stall but higher stall speed.
An interesting question is "Would you rather have more control at a higher stall speed or less control at a lower stall speed?"

len in his analytical way reported the reduction of stall speed (he did a before and after)

i was hoping that when we put the VG at 8% of chord we could improve aerolon authority at or near the stall. no such luck.

len had no negative thoughts, as far as i know, about the VGs

from my conversations with the supplier, they had done VG for certified airplanes prior to developing VGs for Lancairs.

call them, they are very forthcoming

Who are these people? Anybody know?  Just curious.  What do Len Fox and Dave Morss think of these things?

Seems like test pilot reports would be useful.
