The Marquis Winglet performance is a direct result of an increase in effective wing span and the associated reductions in lift induced drag. This is done simply by adding span and redistributing the intensity of the rotating air mass (tip vortex) over a larger area, thus reducing the intensity of that air mass.

Installing a pair Marquis Winglet on your Duke is the aerodynamic equivalent of adding 3' feet to your wings without the complications of replacing your de-ice boots, or cutting holes in your hangar doors.

The vertical span of each winglet is 24" with a 22" root chord, and a cant angle of 15ΓΈ for an actual wing span increase of slightly more than 5" inches at the extreme winglet tips. This keeps the Duke's overall wing span under the magic 40'feet. This was a design consideration for owners with 40'foot hangars.
