  • Improved directional stability and pilot control
  • Reduced drag in all flight modes
  • Improved passenger ride quality
  • Quieter cabin and cockpit
  • Increased climb and cruise performance
  • Inherently reduced minimum control airspeed
  • Eliminate or increase yaw-damper-inoperative altitudes


The strakes eliminate wing/body vortices that disrupt airflow under the aft fuselage and create drag. The strakes instead channel the vortices, accelerating the air to push the airplane through the air.

  • Classic beech ventral fin is removed
  • The shedding wing/body vortices are captured under the aft fuselage, pressurizing and reducing aft-body drag
  • Equivalent vertical tail area is increased
