You see same on Aero Commanders, IIRC. I wrote about it in on e of the early newsletters. BTW, I notice that I do not get any bugs on the horizontal stabilizer from a line tangent to the fuselage to the root of the stab. I gotta conclude th e air is stagnant there. And that's quite a lot of air. (GII fuselage with a GI stabilizer.) I keep thinking about putting HUGE VG's along with side of the fuselage, wh ere it diverges at the flap, to keep the airflow attached, as they did on t he Seawind. But we're talking 3 inch VG's, which look dangerous for getting in and out of the plane.

I can't tell you if they made any difference as I never had the opportunity to fly the aircraft without them, I bought it that way. I can tell you that I remember thinking that I was able to keep the nose wheel off the runway until the airplane was barely moving. In a message dated 9/23/2013 1:23:13 P.M.

Small rudder still so I was looking for some more control. It did work. Building the larger rudder now but will leave the VGs there. Thanks for all of the comments. Any experience is appreciated!

I'm happy with it's performance over all, but I'd always like to reduce stall speed further... Did you see real performance improvements after adding the VG's to your stab? I will look up your newsletter article.
