Well, lets get the design for a fighter out there, in true
LDA fashion

Labordai Dylunio Awyrennau's "Dartiau" light fighter originates from grumbles from our pilots for a new, lighter, faster dedicated fighter. And lo, the creative(most would say insane) minds at LDA have come forth with the Dart, a proposal for a single-man airframe with no tail, instead using a forward-staggered, two-bay, wire braced constant chord, tapered outer dihedral wing which reaches past the rear of the (rather short) airframe combined with a vertical stabilizer in a twin engine pusher configuration(using something they refer to as "gyferbyn â chleddyf") utilizing REW's newest 18-cylinder double-bank rotaries, space provided for a six-cubic foot radio set(when we can get one weighing less than 25lb, that is) and two nose-mounted Cadwynog ŷd machinecannon with its co-developed "Drych" sight, all of their "advanced" metallic geodetic framing and even retractable landing gear.
And, to jsut keep its proposial existant, the
Ilya Muromets Mk2 Clogfeini
Labordai Dylunio Awyrennau's "Clogfeini" bomber is a radical departure from local aircraft design, being a twin-tailed forward-staggered, two-bay, wire braced constant chord, tapered outer dihedral biplane (with solid wings noless, with small fueltanks built within) powered by two wing-mounted engine pods each containing four 18-cylinder double-bank rotary engines(REW's newest offering) in tractor-pusher "gyferbyn â chleddyf" configuration intended to be operated by a crew of atleast 6(10 preferred) and equipped with mounting points for no less than 6 sets of flexible gun mounts(nose, tail, dorsal, ventral-ish and two casemated, one on each side, of which the nose, tail, and ventral mounts contain the new "Cadwynog ŷd AGAA ACD15"(details below). The nose and dorsal mounts are ring mounts, the others are holes with mounting hardware) intended to carry up to 750lb of modified artillery shells in a central bay(able to be amed via modified plotting tables and a version of the Drych sight utilized in the AGAA ACD15) and be equipped with both a GW78 Radio and a Llygad Hir Camera. Apparently the whole thing is based off of a Russian designed commercial airliner that flew even prior to the start of the great war, suitably updated(according to the design notes) with the best aircraft design techniques including improved geodetic framing(including sections made of metal framing as opposed to simply wood) and improvements on our movable control surfaces.
The "Chained Corn" is a two-corn(2/3 inch, 16.76mm) "machinecannon" based off of two identical straightpull firearms setup so that the firing and subsequent recoil of one breach-barrel set operates the action and allows the fire of the other, in essence a modified long-recoil action. The weapon is intended to feed from twin belts(one per weapon). Between the two breaches(if on a flexible mount, of course. In fixed mountings it can be located wherever convenient for the pilot) is also mounted an early "Drych" sight, based upon a lit set of "Gwe Lines" reflected through a lens onto an angled glass plane, allowing the lines to be used to sight the weapon.
Ammunition designed with it are FMJ, tracer rounds, and a APHE round.
And, in an edited-in probably more sane entry, lets get the Archer-lite back into the design pool.
The Aircraft, Design of 1915 "Nodwydd" is an alternative design proposed by Awyrennau Gwynt Cryf-Atebion Mecanyddol Deinamig to cut costs and have a more interception-focused design resulting in a, to dumb it down to its simplest, a single seat pusher-configuration biplane intended to be armed with twin machineguns. Or, to go by the actual design log, "a pusher-configuration biplane(possessing a flat upper high-set and a lower dihedral(which, where it meets the fuselage is thickened to contain a fueltank) wingset in a single bay while wire braced and possessing a forward staggar) crewed by a single pilot, poweredby an improved form of the Rhodri 10-160 D16 armed with twin hull-mounted Cadwynog ŷd AGAA ACD15 machinecannon while possessing a structure consisting of geodetic wooden or duralumin stringers covered in doped fabric varnished to a smooth finish.
