Surprised to find very little info here with a search for Vortex Generators. So here's a couple links and info....

Take a look at eBay.....

Cheapest I've found, and actually may be one of the best designs. I have a set, and will be ordering another for the elevator and rudder.

Home page for the VG's....

I like the looks of the StolSpeed VG's. I have the ones from Landshorter.com and they look exactly like the ones you linked on ebay. While I did notice a pretty good difference with them on at the the "recommended" 10% of mean cord, I read quite a bit on some testing on super cubs and the greatest benefit was around 2.5%-3%. I glued mine on right out of the box because the wanker said that "extensive" testing had shown that to be the best location. Well from now on I am doing my own tests when the weather warms up, I just hate to ruin the paint on the wing to get these damn things off. Hmm, they are made out of lexan, I wonder if dumping a little gas on them will take them off like it ruins the windshields I guess that would be well worth a try!

Leni,

I glued my landshorter VG's on at the 10% chord also. Let me know what you find the difference is if you try them at some other locations.

I think the biggest difference on my plane was on the horiz stab, much better response at slow speed and better sensitivity on the flaperons.
