My dear Stingray,
you forget the S11,it was a compound helicopter project.
the Model-211 was developed from Honcho-100,but with two-seat.
in the book; Rotorcraft of the third Reich,they spoke about NR-53-I and
NR-53-II,as they were an enclosed canopy with undercarriage helicopters,
which they remained only a projects,does anyone hear about them or had
a drawings to them ?.
