Old post, I know, but just to point out that the biplane was not "anther project". The F.K.35 was designed from the outset to be a convertible airframe - able to assembled as either a monoplane or as an unstaggered, equal-span biplane.

A display model was also made of the monoplane configuration equipped with twin floats. Presumably, the biplane could also take a pontoon undercarriage.

I wonder, what the advantage would be, to build this double configuration aircraft?

Gives a choice between more maneuverability and 'stol', or more speed and range.
