I also do not advocate adding vortex generators to your canard. First of all, the laminar flow airfoil, LS-1-MOD, is not a particularly good candidate for vortex generators because of flow separation profile at high angles of attack. Also, no one that I know of has done the testing on vortex generators attached to the LS-1, so placement/spacing would be problematic.

That said, there are more practical solutions to your desire to land more slowly. Jerry Marstall has installed the Dynon Angle of Attack pitot system on his tri-q and he told me that he is now able to control his decent and airspeed more effectively because of it, allowing him to land slower than he had in the past. Maybe Jerry has more comments on that, but I have installed that system on my, yet to fly, Tri-Q, based Jerry's satisfaction with his AOA system.

thanks for your advice. I have been in AVL several times, Earnest built in a Second set of rudder pedals in order to help with transition. So I could do some landings with him as a safeguard and I sure needed it. I know that I have to bring up my flying skills, but at the same time if there are ways to reduce landing speed...

Please read the following SAFETY article on the QBA website
before you continue with your plans:
I am not a current flying Quickie pilot, but I am interested in
keeping you safe. I think it best that you gain some more experience at
a much longer runway, before you rush to bring the plane home. I
appreciate the transition training you're doing with Martin. . . but I
urge an abundance of caution until you've gained more experience in
type. (And even after that I urge continued vigilance.)
an award winning Tri-Q. It is a beautiful plane, and I know you're
excited about owning it. It probably isn't an STOL aircraft though, and
no amount of vortex generators are going to change that. Please don't
try to force the plane to fit your mission. . . adjust your mission to
fit the plane. Unless you would like to bring this beautiful plane home
on a trailer. . . in several smaller pieces. (Or worse. . . bring
yourself home in a much smaller box.)
There are LOTS of experienced
members here in the Yahoo! groups for you to learn from. They are here
to help if you're willing to ask. I wish you the best of luck, but
mostly I wish you a safe and enjoyable experience with your new plane.

I am the guy that boughtEarnest Martins TriQ200 and he is very helpful in transition training.
We built in a second set of rudder pedals, so he can interfere from the
right seat when I screw up.
We flew together for about ten hours lastweekend and plan to do so again before I take the plan to my home
Airport, which has a fairly short runway of 3800feet.
So I look forways to reduce landing speed. RIGHT NOW WE ARE AT 100 across the
threshold, and landing at 80...
And I hoped to be able to reduce by10percent, maybe vortex generators can help
