Adhedral stabs make a noticable difference, while the small canalizer has no big effect. It might help a tiny bit, but not as to a point where I need it on my airplane. The big T canalizers (I guess thats what you call them) such as on the oxai model flown by the french guy make a difference, as it is a 1.5 wing kind of plane.
OK, I'm gonna ask. How do you explain that it has no effect? Putting a simple 2" X 2" strake in that location makes a HUGE difference, even without the wing. It definitely cleans up the airflow back to the tail. There are other ways to get the same effects, but I don't think you can say it has no effect, as I've flown planes that it had a HUGE effect on. The Black Magic VF3 series from Mike Hester is a perfect example. The plane is over 5 years old and had limitations with some of the much more rudder heavy maneuvers in FAI. Don Szczur added the T-Can and I have flown the plane. It made a HUGE difference. They do have an effect. Some planes do not need them, but to say they have no effect is a little much.
