SQ-12 is a Wayne Mackey creation. I think he stays busy enough without marketing. There are a few wider bodied SQ-2s from Backcountry flying around that guys call SQ-12 but they aren’t the same. I know three flying SQ-12s and 4 more being built, all nearby here in Alaska. Very impressive airplanes. State of the art. Like Backcountry airplanes the SQ-12s continue to evolve so none are exactly the same.
