“We’re not the first to call it an upside-down Sling. When company test pilot, Sean Russell, talks about the airplane, he refers to it as “the upside-down one.” Indeed, if you look closely at the wing, it does appear to be the same as the one on a TSi sitting beside it—because it is. The metal, pulled-rivet-construction wing is simply grafted to a new fuselage designed for roominess and easy entry. (No, it actually wasn’t quite that simple.)”
