Bill, I am at the point of installing vgs on a Long EZ that has a slick

wing

(never had vortilons or vgs). From your educated viewpoint, can you

offer some

suggestions on % of chord to mount the vgs for max lift / minimum drag

and how

close to space them. Also, most I have seen were mounted in pairs with

counter

rotation. Could they be just as effective mounted all the same

direction?  What

angle off center line? Recommended height and length?  Any help will be
appreciated  In current state & at 1600 lbs, and cg at about 102.5, the

Long will

fly final @ 80 kias and land at about 70 kias. Pitot is flush in nose

and may be

indicating a little low at low speed.   Thanks, Herb Sanders

Hi Herb,

Glad to hear from you.  The answers to your questions will take some time
to answer.  There is a couple of possible problems facing you and I want you
to be aware of them all.  I do believe verbal discourse would be the best
way to
go. Give me a call around 7PM any day and I'll talk your ear off. Now don't
anyone else read this: (757) 851-1298.

Fly fast, land slow.
