The pioneer aircraft in cantilever wings suffered from poor visibility with its top-mounted open cockpit.

The follow-on aircraft, the Stout Batwing Limousine, would have a conventional fuselage and engine arrangement, and a tail mounted further aft.

The all-wood cantilever wing did not need struts or braces, reducing parasitic drag on the aircraft.

[1] Stout acquired financing for the project from Robert Stranahan of the Champion Spark Plug Company.

Bert did claim the plane was stable enough to fly with his hands off the controls for several minutes at a time.
