Vortex Generators Installed

 Using the vortex generator installation instructions on the Cozybuilder web site, and the Stolspeed Vortex Generators from ACS,

Pictures and performance reports to follow.

Canard stall speed was 62-64 knots previously.


----update 6/21

Stall speed appears to be at 60-62 knots now.  At around 80 knots, the canard is in turbulent air and starts shaking a little.   The stall break seemed to be more abrupt.  Probably the best example of how it feels is that it's like driving on new pavement (without VGs) or driving on a rough concrete road (with VGs) at lower speeds.


I'm noticing a right roll tendency now. Not sure if it was there before.   I'll consult with Vance.


-----update later in Phase I

I pulled the VG's off since there's a bit of a roll to the right.  Corrected the roll with a washer in the left wing.
