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
