The Vortex Generators for the Cessna 340A, 340, and 335 are FAA STC approved and ready for installation on your airplane. This jet age technology provides virtual elimination of Vmc, a dramatic improvement in characteristics, reduced stall speeds, reduced approach speeds, reduced accelerate/stop distance, and improved safety. You also get a 300 pound Gross Weight Increase. The VG Kit consists of 102 vortex generators mounted on the wings, just aft of the boot line and on both sides of the vertical stabilizer, plus two strakes (similar to the strakes which Cessna puts on the 303 Crusader), on the outside of the engine nacelles. The VG Kit includes an FAA approved Pilot's Operating Handbook Supplement and all of the installation tools and materials for your shop to make the easy one day installation. The Vortex Generators are manufactured under our FAA PMA from aircraft grade aluminum and are alodined to a Boeing mil-spec. When placing your order for a VG Kit, please provide the Serial Number or N-Number. We can ship the same day if your kit is ordered Alodine, ready to be painted. We can paint the VGs to match your airplane for an additional $150 per color. Painted kits will ship within 3 days. As one Cessna 310 owner said, "The VGs do everything you said they would do and more -- the tail of my 310 thinks it's four feet taller and the rudder thinks it's two feet longer!"
