As I posted earlier the ultimate proposed configuration of the Zimmerman pancake would have had tip mounted small diameter turboprop engines (here things get murky, as to just what engines were proposed- Napier Niad (same as Convair 600 conversion) or half a T-40). This for later Navy VTOL program, so I assume some hover capability was available with the much improved power/weight ratio.

Whoever designed the German flying wing mock-up was really a student of that-time technology. The beautiful blade contours of VDM propellers was retained. Also the Arado-like attackers in a later Indy movie, complete down to the pitch change vanes on the spinners.
