Mark, Actually I should have said that vortex generators are effective on swept wings, such as the vari-eze and longeze, velocity,etc. The airflow seperates from the top of the wing more on swept wings than on straight ones. Vortex generators are like small gates or dams that make the airflow stick closer to the surface for a longer portion of the wing surface. It makes the wing fly better at slower airspeeds. This is about the best I can do in general terms. You can read more about the subject on some of the canard aircraft sites. Rick Wilson. ps. That was my point, they don't help that much with bugs or rain.
