Indeed, I have - well, sort of.
Spruce Creek is a tricky strip to land on. Lots of trees, hangars and 
gaps in between - lots of lateral control required and the Velocity 
just didn't seem to deliver that unless I landed it fast. So, I 
decided to do something about it and VGs seemed the way to go.

By the way: kudos to Brian Michalk for his very vivid discription on 
how they work.

So I added a row of VGs in front of the aillerons just about where 
the factory template says to put them. Since I was not so much 
interested in lowering the lower speed limit than to improve the 
controllability at landing speed, I didn't put VGs on the canard.

Well, the result is: it feels a lot more responsive. For a physicist 
this is a terrible result, isn't it? Gimme the numbers!! right? Fact 
is, I don't have them. For a number of reasons, I didn't have the 
opportunity to fly the Velocity since these first "feeling flights" 
and will not for a while, so I hope Jim Sower can figure out a 
quantitative test program. I am pretty sure the results would reduce 
the incidence of landing accidents.

Best
Simon
