"technology", FanWing. (retrieved 5 January 2018): " OHS Development (Outboard Horizontal Stabilizer) The recently developed TwinTail configuration, suggested originally by former BAE Systems Principal Concepts Engineer, George Seyfang, avoids the strong downwash flow directly behind the wing and exploits the upwash from the wingtip vortices. The new design has increased the efficiency of the aircraft by between 10 and 15% and also improved pitch stability."
"July 2011: FanWing Modified TwinTail 2011", News, FanWing (retrieved 5 January 2018): "Following two series of wind-tunnel tests and analysis from January-June 2011 the newly modified TwinTail prototype was first flight tested June 18th and most recently July 16th 2011."
