Does the VG kit for the Seneca II include an STC?
Yes, all the Micro vortex generator kits for certified aircraft will include the STC. Only the vortex generator kits for experimental aircraft will not include the STC.
Regarding the vortex generator for the Piper PA-28. What is included with the kit? Can you do them in customer color, specifically white? How much will it reduce stall speed?
The kit for the PA28 contains 3 different part numbers for different locations on the aircraft. There are 4 extra of each part number (12 total) included as spares with the purchase of the kit. Please note that the painting option is available for an additional charge per color, and we require the paint name and color code number to paint. To paint the parts "white", this charge applies, and we need the code information. The vortex generators can reduce stall speed by 5 MPH.
What is the weight increase with the kit for the PA22? What are the numbers for the reduction on takeoff and landing rolls?
Per the supplier: "With the installation of Micro VGs on the PA22-150, there is a reduction in stall speed, but change to the take-off weight. The takeoff and landing distances are reduced due to the reduction in stall speed. Since we did not certify new performance charts for the flight manual, I do not have exact numbers for you. For take-off, the stall speed at gross with flaps UP is 53 mph (instead of 58), so the plane will fly at 54 mph, which allows for a shorter takeoff. For landing, the demonstrated stall speed with flaps full is 47 mph (instead of 53 mph). This will allow for slower approach (1.3 x 47 mph) at 61 mph at gross which translates into shorter landing distance."
