Just curious, what size wood are you using for your fuselage sides?  Making good progress!

This is the idea for the wing construction...laminated 1/8"x1/16" for the LE...1/16" sq laminated for the TE...cracked 1/16"sq for the ribs and spar.  Bottom wing to be constructed similarly...in fact, bottom wing planform is same basic shape and size (shorter) as top wing...excepting ailerons, that is.

Here's a reference book I've had on the shelf for years...and a rare pic of the observer's Parabellum up above.  Wouldn't that be a fun place to be while a pilot (in the rear cockpit) suddenly took evasive action.  Shocked  Brave souls all.

Thanks, fellas...should be a fun build.  Fuselage is very straight forward...very typical of German WWI two-seaters...in fact, the fuselage looks like a Rumpler.  The wing is another matter.  Plan (pun) is to laminate the curved leading edge as well as spars...ribs to be cracked-type.  The cabane struts are a modelers' delight...like a saw horse.  Should be fun...and interesting.

Found these pics of a DFW being constructed over on Mike Stewart's website.  Mike says apparently not easily trimmed...for whatever reason...but then, all my models are not easily trimmed.  Roll Eyes

I was surprised to read that the original DFW MD14 design utilized a steel tube fuselage...pre-WWI!  Appears someone liked the idea of a more-sturdy setup of plywood skin.  The observer was generally armed with a handgun and/or rifle...and occupied the forward cockpit.  Strange setup.  Late model B-II had a top wing center cutout with an mg located above the wing.  Observer had to climb up to operate it.  Oh boy.  Advent of the C-type got thing arranged properly.

I look forward to following this one.  You definitely have found an unusual aircraft to model!

Enter the “Flying Banana,” the pioneering design DFW B-1.  It was actually a quite successful pre-WWI design by the Deutsche Flugzeug-Werke that utilized a steel tube fuselage…later changed to plywood skinned.  It’s pre-war designation was DFW MD 14, pressed into military service and changed to B-1, denoting an unarmed two-seat observation class biplane.  The nickname “Flying Banana” was derived from the crescent-plan form three-bay wings.  For me, it resembles a giant moth.  By mid-1915 it was retired to training duties in favor of DFW C-class designs, armed with a standard configuration observer/machinegun.

Alas, no plan…at least none that I encountered.  So to locate a descent 3-view…and from that, create a plan.  This is an aircraft with a big wing…so the build is mostly…wing.  I’ve chosen to build a 16” ws…which means the fuselage is basically peanut-scale size, in keeping with my approach to storage area conservation.  This is NOT really a dimer...but in the interest of attempting to "soothe the savage beast..." got to find a roost.

Unusual airplane….
