Don't own one, not working on one, but I like them a lot and would like to build a Patrol. They just announced improvements. From [email protected]

Additional changes incorporated into the Bearhawk Bravo are:
  • Use of aluminum fuselage formers, window sills, and door sills in place of steel formers and sills offering weight savings and corrosion resistance.
  • Use of airfoil shaped ribs on the horizontal and vertical stabilizers as opposed to flat ribs giving enhanced stability, more control authority, and a speed increase of three MPH due to the change from four to three degrees of down deflection of the horizontal stabilizers.
  • Use of shock struts made from heavy wall round tubing in place of streamlined tubing providing more resistance to side load failure while on the runway. The round tube is faired with streamlined PVC to neutralize drag.
  • Use of a round tail spring fabricated from 6150 heat treated alloy steel bar in place of the leaf-type spring set providing a small weight savings and better flex/spring effect in any direction. The round profile also has the potential to save the rear fuselage from damage at unpaved strips.
  • Use of the aforementioned Riblett airfoil wings with one-foot longer wingspan and an additional five square feet of wing area.
