I'm curious about the SQ line of aircraft, they are amazing performers, but seem to be almost one-off airplanes. Saw John Bush's in Valdez this year and was very impressed. Is Mackey just building these himself and selling them or can the average Joe purchase components/kits? I know he and backcountry parted ways a couple years back, and I haven't heard much good about backcountry's customer service. It seems a shame that they are about as close as a guy can come to the Mackey birds.
