RE: Pusher Prop Thrust Line Offset from Datum Line
The vertical chunk at the rear in the location typically reserved for the vertical stab is a 12" diameter ducted fan assembly with a 4 blade prop spinning at a low low 13K. The vertical stab will go down from the fuse rather than up. The center of the fuse is reserved for a vertically oriented ducted fan for VTOL capability. Just thinking out loud.
