REFLECTOR: Vortex generators

[Michael Watson]

I've had VGs on wings and canard for nine years now, I would
feel very uneasy landing a Velocity without them.

During my first year flying without them, I came over the numbers
between 80~85 KIAS. That speed gave the feeling of positive control
of rudder and ailerons. I felt that for safety. that seed was just too high.


After installing the VGs, I would have that same feeling between
67~72 KIAS. Due to the slower landing speed, the plane stops in
a shorter distance saving ware and tare on tires and brake pads.

I have had the airspeed down to 63 KIAS at altitude and it did not
pitch buck. After ten years, I still do not know at what speed it will
start to pitch buck.
