Continuing in the spirit of this thread -- Cute 1928 Peyret-Nessler Libellule parasol monoplane -- here is another interesting French light aircraft highlighted by late model builder Emmanuel Fillon. The Volland V10 is a biplane with so much stagger as to be a 3-surface design back in the 1930s. Eat your heart out Burt Rutan!
The period article attached refers to the configuration as a "Darmstadt biplane" after a pair of similar designs developed by the flying club of the German university of the same name, so I have included both Darmstadt and Volland plans from Fillon.
There is some food for thought here in terms of aerodynamics, for example, the pronounced stagger with ailerons on the lower/rear wing should give excellent stall characteristics if the airfoils, wing loading and incidence chosen force the upper/front wing to stall first. Cockpit access is also certainly easier than in most biplanes.
Cheers,
Matthew
