Piper Dakota

 

The FAA has approved Micro AeroDynamics vortex generators for the tapered wing series of the Piper Dakota’s.  The new STC covers PA-28-151, PA-28-161, PA-28-181, PA-28-201T, PA-28R-201, PA-28R-201T, and the PA-28-236.

Flight test have shown that the Vortex Generators provided a nine percent decrease in stall speed, a faster roll rate and increased stability in slow configurations.  The vortex generators allow the boundary layer of air to adhere to the aircraft longer in high angle of attack and slow speed configurations.

The VG’s are made of aircraft grade aluminum and can be painted to match the color scheme of your aircraft.  They can be applied in one day and cost around $1,450.  The VG’s are glued on with Loctite Depend and are 1″ by 1/4″ high.

Micro AeroDynamics claims that there is no top end speed loss, but generally there is a 1-3% loss of top end cruise speed with VG kits.
