Micro Aerodynamics receives FAA approval for vortex generators for Stinson 108

The FAA has issued an STC to Micro AeroDynamics to produce Micro Vortex Generator kits for the Stinson 108 through 108-5 models. The jet-age technology provides the venerable classic with an 8% reduction in stall speed, improved aileron response and a reduced takeoff and landing roll, say Micro Aerodynamics officials.

The company now holds VG STCs for more than 500 models of aircraft.

The Micro VG Kit for the Stinson consists of 68 vortex generators that are attached aft of the leading edge of the wing. Another 32 VGs are positioned under the leading edge of the horizontal stabilizer. The VGs, which are only 1/4-inch high and 1 inch long, are curved to accommodate airfoil contours. Their placement has the effect of keeping the boundary layer attached to flying surfaces, allowing for higher angles of attack and lower stall speeds.

Manufactured under an FAA PMA, using aircraft grade 6063-T6 aluminum, the VGs are alodined and ready for painting.

Complete kits sell for $695, plus shipping and handling. They can be painted to match the aircraft’s base color for an additional $100.
