Douglas McHard's superb 8th scale free flight model of the fabulous 1917 fighter for 1.5 cc engines.
The full-size Albatros D.V was a developed version of the famous D.III as flown by Von Richthofen and detailed by George Cox in his Famous Biplanes series last month. It made its first appearance on the Western front during 1917 and the most noticeable new feature was the beautifully streamlined fuselage which replaced the somewhat flat-sided shape employed by the earlier D.III.
Although no subject for the raw beginner to tackle, the elegant lines of this authentic flying model will fully repay the experienced builder for the extra effort involved. For this is truly a scale connoisseur's project. It is the most detailed single-engine scale-model plan in Aeromodeller Plans Service and the sight of the prototype in the air on flight tests, takes one right back to that famous era of two-gun biplanes fighting it out over the Somme.
One major reason why this model did not appear, as promised in our December issue, was because the flight tests called for further work on the design details. In our endeavour to see that the APS drawing provides full data for a foolproof model, we spent extra time on this beauty. An initial flying problem was that of side-slipping, which although most realistic in the extreme and probably a scale characteristic adopted from its full-size counterpart, was not the sort of flight path desirable in an otherwise stable model. Happily, this and other minor points have been overcome in the final design and with incidences, engine angles and the balance point specified, the Albatros is a certain flier and one in which all keen modellers will revel.
The 1/8 square balsa used in constructing the fuselage side frames should be carefully selected for its uniformity and firm texture, for upon the accuracy of this basic construction depends the entire alignment of the model. Build the two frames one on top of the other and when completed, allow them to dry out thoroughly before attempting to separate or remove them from the plan. In the meantime, cut out the bulkheads, paying particular attention to the plan notes on the material to employ.
The 1/8 ply bulkheads should be cut with a fretsaw. If 1/8 ply is not obtainable, a satisfactory substitute would be 1/8 inch hard balsa with 1 mm ply front and back. Where large areas are to be laminated (for example, the wheels and exhaust pipes), the drying time can be drastically reduced by employing one of the contact adhesives, such as "Evo-Stick" or Goodyear "Pliobond" in place of cement. A further advantage of this type of adhesive is the complete absence of warping.
The two halves of the 1/16th sheet formers should be joined together and reinforced by two pieces of 1/8 x 1/8 balsa as indicated on the plan. Formers Nos. 3, 5, 6, 8 and 9 are now assembled on the engine bearers and the lower flying wire anchorage hook cemented to former 9. Check the plan view for the correct sidethrust angle.
Bend the undercarriage main legs from 12 s.w.g. piano wire and bind them to the motor bearers. This binding is best done with copper wire and then soldered, however, tough thread will do provided you bind tightly, use sufficient and cement liberally..."
DDP Thema, AVRO 504 K
AVRO 504K van Ray Booth.
Type Model FF Scale Biplane
Engine Amco .87cc
Surely no other type of aircraft was so much responsible for the development of "airmindedness " as the Avro 504 K.
Originally produced in 1915 to train pilots for the RFC the 504 appeared in several versions, the K type being the most well-known. From 1932 to 1938 dozens of these 'Old Avros' - as they were affectionately known - toured the country giving joyrides at 5/- a flight. Probably more people had their first experience of flying in the 504 K than in any other type of aeroplane up to the end of 1938, at which time these grand old machines were no less than 23 years of age.
Our cover painting depicts a typical example formating with other machines of Alan Chobham's famous circus.
It is said that the stability characteristics were of such high order that in the event of difficulties in flight it was only necessary for the pilot to remove his hands and feet from the controls, and the machine would automatically return to straight and level flight. What better machine then could one choose as the subject for a flying scale model?
The performance of the model has far exceeded my most conservative estimates, and although it has only been entered in three competitions, this model has so far collected the Aeromodeller Champion of the Exhibition Trophy (Northern Models Exhibition, Manchester); 1st Prize in the Flying Scale Section at the same exhibition; 2nd Prize in the Model Aircraft Section at the Manchester and Districts Society of Model and Experimental Engineer's Exhibition.
Although the prototype has always been flown with an Amco .78 cc Mk 1, any motor of similar power and weight should be satisfactory. Throughout the design my aim has been strength and durability, and consequently at first glance it may seem rather heavy. Let me hasten to assure readers, however, that the flying and gliding speeds are only about half of that of normal power duration models of similar span, due to its relatively large large wing area. The wings are arranged to knock off in the event of a crash, all bracing wires being 1/32 square rubber... "
DDP Thema, RAF F.E. 8
AeroModeller December 1952: RAF F.E.8. scale biplane pusher van Vic King
Engine Mills .75 power
"A pusher model is not everyone's choice, and a scale pusher is one of the most difficult selections it is possible to make. The reason for this being the need for so much nose ballast to compensate the engine weight, that wing loading becomes too high for reliable flight. But if the model is relatively small, this difficulty is minimised to a great extent, and in choosing the famous FE.8 and building to a scale suiting his Mills .75, Vic King has proven that the pusher can be as realistic and reliable an old timer as any could wish to see.
Few can grumble at its 14-1/2 ounces for 350 sq in wing area, a far more generous loading than we find on many a conventional scale model, and the hundreds that have been fortunate enough to witness the prototype's flights at Fairlop and thereabouts will verify that here's a model that definitely carries the air of 1914-18 about it.
The full-size aircraft has been magnificently portrayed by artist Rupert Moore on the cover, to give builders as accurate a colour guide as possible, and in 'Hangar Doors' Mr Moore writes further on the subject. The FE.8 was produced in company with the DH.2 to combat the Fokker Scourge, and gave a very good account of itself during its ten months of front-line service. Fokkers were using interruptor gear to synchronise machine guns firing through the airscrew; but with the engine at the rear, such a device was not necessary, hence the series of pusher Scouts, before we developed the synchronised gun.
Construction. Cut the fuselage sides from sheet, add formers, cement in engine bearers and cover top and bottom with sheet. Insert wire struts then cut outline of cockpit. Wings are perfectly conventional, except for the brass tube fittings which must be packed to protrude just outside the wing contour.
Unfortunately the tailplane had to be altered slightly from true scale in that it is placed on the model in the inverted position to provide a down-ward lift. Its construction, like the rudder and fin halves, is perfectly straightforward. Make certain that the pendulum rudder will swing freely, and that movement is limited by the stop and also by the pendulum arm on the fin.
Good quality spruce dowel is essential for the booms, which should be glued together and not cemented. It is most important that the brass tube at the end of the boom receives the wire spacing piece smoothly. At the forward ends, the booms are connected to the wings by the tube fittings, and a securing elastic band goes over the top wing as shown..."

DDP Thema, Sopwith Snipe
AeroModeller July 1957:
The world's first single seat multi-gun fighter the Dolphin represented a departure from traditional Sopwith fighter design. In place of the rotary engines so characteristic of the Triplane and Camel the Dolphin was equipped with a stationary 200hp geared Hispano-Suiza in-line engine.
The Dolphin's unusual wing layout with its 'backwards stagger' was designed to provide the pilot with excellent all round visibility. This was achieved by placing the upper wings low on top of the fuselage, the pilot being positioned with his head in the centre where he was afforded a clear and uninterrupted view. Dolphins flew their initial front-line patrols in February 1918 and eventually equipped five RAF squadrons. During the German offensive of 1918 Dolphins conducted ground attack operations, bombing as well as machine gunning enemy troop concentrations.
Popular with its pilots the Dolphin was a highly potent fighting machine but its success was limited due to problems afflicting the geared Hispano-Suiza engine. Dolphin production ceased in August 1919 and the type was declared obsolete in September 1921.

DDP Thema, Airco DH-4
AeroModeller August 1960 (Special International Issue):
Airco DH-4, 1916; type DH.4A: 1919,
Na faillisement van Airco in 1920 werd De Havilland opgericht. Dit werd een succesvolle vliegtuigbouwer. De DH.4 was een Engelse tweezits bommenwerper maar werd ook voor verkenning gebruikt. Het had twee open cockpits, en een conventionele houten constructie. De romp had een triplex bekleding tot de achter cockpit maar de staart en rest had een linnen bekleding.
Het type zou in eerste instantie Beardmore motoren krijgen, maar deze waren niet leverbaar. De Rolls Royce Eagle motor werd daarom toegepast, alhoewel sommigen ook de RAF 3a, Siddeley Puma of Fiat motor kregen.
Een operationeel probleem was de grote afstand tussen de piloot en boordschutter, deze bemoeilijkte de onderlinge communicatie. Het toestel vloog nog wel eens in brand door slechte constructie van de tanks. Toch werd het type beschouwd als de beste Engelse dagbommenwerper want de kist was relatief snel. Veel toestellen werden ook in Amerika in licentie gebouwd en meer dan 3200 kisten met een Liberty V motor. Na de Eerste Wereldoorlog werd het type veelvuldig ingezet voor andere taken en zelfs als verkeersvliegtuig (o.a KLM).

DDP Thema, Sopwith Dolphin
AeroModeller March 1962: Sopwith 5F.1 Dolphin:
Early in 1918, British squadrons at the front began to receive an entirely new type of fighter, the Sopwitb 5F.1 Dolphin. As a matter of fact, research discloses that Dolphins were first received by No.87 Squadron in December of 1917. With its inverted staggered wings and bulldog nose, span of about 32 feet 6 inches, and four machine guns, it was indeed something out of the ordinary.
The 200-hp Hispano-Suiza engine gave it a top speed of around 122 mph at 10,000 feet; this height was reached in 12 minutes. Maneuverability was excellent and the open space betwen the top planes gave the pilot a fine range of visibility. The two Vickers guns were mounted conventionally on the cowl; the Lewis guns were mounted on the forward spreader between the top planes. These two additional guns fired over the propeller and could be elevated at will by the pilot who had to be a dandy to fly and fire these guns at the same time. No.87 Squadron remounted the Lewis guns outside the propeller disk on the lower wings where they were fired by means of Bowden controls.
This seldom modelled First War fighter was actually built in fairly large numbers: over fifteen hundred Dolphins were completed of which about 400 were consigned to the Western Front. Nos. 19, 23, 79, and 87 Squadrons were entirely equipped with this ship. No.85 Squadron received Dblphins to augment their SE5As. Had the war continued longer, Dolphins and Sopwith's 7F-A Snipe would have eventually equipped most of the British fighter units.
