Has anyone heard of them on models.

BT....I dont know of any at this time but quite sure they would be effective if installed....depending on size of plane you'd be putting them on probably would be a tedious job on smaller models....carbon fiber might work very well to make them .....Bill.....

I installed counterrotating vortex generators on a Skyburner several years ago to solve the tendancy of the a/c to drop a wing in the flare. This along with wing fences solved the problem.
I fabricated the generators out of clear lexan. There are 3 sets on each wing.
Maybe turbulators toward the leading edge would have had the same result.
A bit difficult to see in the photo, but they are toward the aft end of the checkerboard.

I was mainly asking about small wing turbines or DF's. ie 104, or F-5. Thanks for the info, will do some more research on it.

You guys are all wrong the name of the game is leaed sled's.

What are you talking about?

Vortex Generators - better known as VGs are small metal/composite flat attachments on top of wing, inline with the airflow.

One of the reason they are there is to help prevent early air flow separation during slow speed, and high AOA. When installed in front of control surfaces such as ailerons on the A4-Skyhawk, they can help increase control effectiveness.

In general aviation, VG can help decrease landing speed, and also increase top speed by smooth out airflow on wing.

Hope this help...go look for a pic of the top wing of the A4...you see what I mean.
