REFLECTOR:Vortex Generators on XL

[Chuck Jensen]

Jack,

Everything I do is trial and error.....though I did use the patterns
provided by Velocity.  They are installed on both the canard and wing (and
both sides, naturally).  I don't remember the exact count but buy a 100
(they're cheap) and use the extra for replacements.  To paint them, after
scuffing the bottom on sandpaper, I just stuck them on packing tape and gave
a few light coats of enamel for UV protection.

Do us a favor.  Before you install, do a few altitude stalls and see if you
can nail a number.  After installation, repeat and see what difference, if
any, you note.  Maybe you already have a hard number for touchdown IAS that
you can reference---that would make a before/after comparison even simpler.
Most seem to think it reduces touchdown by 5 to 7 kts.

Chuck,
Do you have them on both the canard and the wing? Did Velocity 
provide installation pattern or was it trial and error eyeball
