STOLSPEED Vortex Generators Performance Enhancement for Light Aircraft

Long Ez
Time to replace the old vortex generators on the GU canard of my Long Ez; need 120 clear ones. I built the airplane, have almost 2000 hours on it, powered by an O-320 Lycoming. The VGs are used primarily to reduce or eliminate the pitch change associated with moisture. I've tried various types and locations, and have it pretty much figured out. I took off the old VGs to repaint, but damaged some of them, so I thought I would try yours instead.
I'm a former US Navy A6 pilot, and graduate of the US Navy Test Pilot School, with about 6000 flight hours.
Took a couple of hours to install the VGs; from prior expience with the GU canard on the Long Ez, I put the vgs just aft of the 50 percent chord, once inch apart, angling in at 15 degrees.
I had a significant pitch down in rain that has been eliminated (same results with the old VGs). Went for a spin in the rain and it flies fine.
Straight forward installation;
I especially like the adhesive sheet. Much less messy that using liquid adhesives.
This would verify that your VGs address and solve the pitch change problem with the original Long Ez and Varieze GU canard.
Thanks for a nice product.
