Triplane Top Gun: Josef Jacobs’ Fokker Dr.I

“One for the folks back home!”

There is no more iconic World War I aircraft than the Fokker Dr.I. The distinctive triplane has appeared everywhere, from movies and books to comic strips and frozen pizza packaging. When it first arrived, it was a boon to German pilots, whose Albatros, Roland and Pfalz fighters had become outclassed.

 

Arriving in late October 1917, the Dr.I was eagerly awaited. Werner Voss had used a prototype Fokker F.I to destroy seven enemy aircraft in 20 days before being lost himself in a battle with six SE.5s. The Dr.I possessed superior climbing ability and was terrifically maneuverable, making it an excellent dogfighter. It also had two guns at a time when many of its adversaries still mounted one. However, the triplane configuration caused a lot of drag, so the Dr.I was slower than its adversaries.

 

Still, the plane’s nimble qualities tipped the balance to the Germans – briefly. In late October and early November, a spate of accidents led to the grounding of all Dr.Is and a reversion back to the Albatros D.Va. Moisture accumulating in the upper wings was loosening the glue joints to the point where the ailerons failed, leading to the failure of the upper wing. All the Dr.Is went back to Fokker’s factory and a series of 12 improvements were instituted. The Dr.I returned to combat on November 28. By then, however, any tactical surprise was gone, as were Anthony Fokker’s profits from the machine.

 

Despite the triplane’s iconic status, the structural issue limited production. Only 320 Dr.Is were manufactured. A number aces preferred the machine even as it was surpassed by the superior Fokker D.VII. One of these was Josef Jacobs.

 

Jacobs was a veteran by 1917. His combat career began in July 1915 in reconnaissance machines, flying long-range sorties over allied positions. He downed a Caudron in February 1916, but this could not be confirmed. Jacobs was transferred to Fokkerstaffel-West to fly the Fokker E.III, and his first official victory came on May 12 when he destroyed another Caudron.

 

Jacobs scoring was curtailed by a bout of dysentery and eventually he was transferred to Jasta 22, where he scored three more confirmed victories. He became commander of Jasta 7 in August 1917, where he shot down and killed nine-victory French ace Jean Matton to achieve ace status himself. Early in 1918, Jacobs switched to the Dr.I and became its most lethal pilot, downing more than 30 allied aircraft with it, often leading the rest of his unit’s Fokker D.VIIs into combat in his triplane, an all-black machine with a fire-spitting character called “the God of the North” emblazoned on both sides. Jacobs’ final score was 48 aircraft and balloons, placing him fourth among German aces.

 

Following the war, Jacobs continued fighting, flying against the Bolsheviks in the Baltic, and later became a flight instructor in Turkey, then switched from aviation to sport, excelling in auto, speedboat and bobsled racing (he was the president of the German Bobsleighing Society in later life). In the 1930s, he started an aircraft repair and manufacturing company in Erfurt. Hermann Goering personally asked Jacobs to join the Nazi Party, but Jacobs refused; he also refused to allow Goering to become a major shareholder in his company and moved it to the Netherlands. When Germany invaded, Jacobs had to go into hiding, but he returned to Germany after the war. Jacobs died in Munich in 1978, the last surviving recipient of the Pour le Merite.

 

Eduard had the good sense to put Jacobs’ top-scoring triplane on the boxtop of its 1:72 “Profipack” release. The “Profipack” kits feel a little like cheating, since nearly everything you could need is already in the box. In this case, that meant the plastic parts for the tiny fighter were accompanied by a fret of photoetched parts and masks for the wheels. These were all quite nice – but, of course, I couldn’t resist the urge to add more.

 

First, I cut off the plastic molded structure inside the cockpit and removed the plastic rudder pedals, as instructed in the kit. This detail would all be replaced with photoetched parts.

 

The kit doesn’t include the triangular plywood panels inside the fuselage that helped define the fuselage’s shape. I cut these from sheet styrene, painted them with beige enamel, and then dabbed on some Minwax wood stain. While it was still wet, I lightly dragged a paper towel across the stain to streak it, giving a wood grain effect. This was repeated on the cockpit floor and rear bulkhead.

The plywood panels at center, along with the prop in its first stages of painting and the cockpit floor.

The cockpit frame was folded together and painted a shade approximating RAF sky – this is a close match to the color used by Fokker for its internal framework. The instruments attached to the frame were bent into place and backed with tiny sections of styrene rod painted black, and their pre-painted faces received a drop of Future floor polish to replicate glass. The photoetched fuel pump was given a light coat of white glue to give it a degree of three dimensionality, and after it was painted it was installed in the cockpit framework. The same went for the throttle assembly; it was painted, received a styrene rod grip, and was added to the left side of the cockpit framework.

The completed cockpit framework, added to the right fuselage half.

 

I used white glue to beef up the grips on the control column, then folded the combined column and rudder pedals, painted them, and added them to the floor, along with some styrene strip footboards. The compass holder was folded to shape and painted before getting its decal face, followed by Future for the lens; once dry, this was added to the framework as well.

 

The seat was painted in facsimile wood colors and, when dry, the kit’s pre-painted seat belts were added with CA glue. The seat went on the rear bulkhead, the rear bulkhead was joined to the floor, the floor was added to the framework and the whole thing was glue into place in one of the fuselage halves. The fuselage was closed in near record time for one of my builds!

The next step was to assemble the guns. As nice as Eduard’s were, I opted for the stellar Mini World Spandaus, which have a machined body and photoetched cooling jackets and sights. These spectacular little guns were painted a gunmetal color and dry-brushed with steel, then had their cocking handles picked out in a wood color. They were then set aside in a safe place – they can be very delicate and easy to damage until they’re on the model.

Mini World Spandaus – and by “mini” they do mean mini!

I cut the molded-on control horns from the tail and upper wings , then cleaned up these areas. The “Profipack” kit includes these as photoetched items, which would be added at the end of the build.

 

The vertical rudder was painted white, gloss-coated and decaled. When it was done, it went to safety with the Spandaus. The horizontal tail was added to the fuselage, and I found the fit fussy, but with a little sanding I obtained a good fit. The center wing went on next, followed by the ammunition box, which was painted aluminum. This fit ridiculously well – so snug I was concerned I couldn’t get it apart after test-fitting it! The lower wing joined to the fuselage with precision, and I had no worries about alignment to the center wing.

…with the lower wing installed and perfectly aligned.

For now, I veered off the instructions’ path and instead painted the model with a coat of ModelMaster interior black. That meant painting the fuselage and lower wings, upper wing, struts, cowling and landing gear before assembly. The overall black scheme lent itself to this. A coat of Future prepped the model for decals; the kit decals went on with no problems and I added decals to the fuselage and upper wing in advance of assembly. Another coat of Future sealed them.

How much more black could it be? Theanswer is none. None more black.

The firewall ahead of the engine was painted steel and I set to work on Eduard’s wonderful little powerplant. This includes a plastic bank of cylinders, brass ignition wires for the front and back of the engine, and detailed photoetched hub. The prop “shaft” is fixed in place on the firewall and the engine and propeller spin around it – just like the real thing.

The propeller was cleaned up and masked for a wood grain finish. This involved painting the prop a light shade of wood, then carefully cutting masks, front and back, to replicate the laminated layers of wood in the prop. A darker shade was sprayed, and the contrast seemed extreme until I brushed on a coat of Tamiya clear amber. This made the prop appear varnished and tied the shades together nicely. Manufacturer’s decals and the photoetched hub plate were added to finish off the propeller.

After a coat of Tamiya clear amber, the prop looked properly varnished.

Now, I began to bring the elements together. The wing struts go through the center wing and all but guarantee proper alignment – if you get them oriented correctly. They have a subtle front-to-back orientation that’s easy to miss (which I did at first). The landing gear came next; I first drilled holes for the wire bracing, then assembled the gear struts and wing and added them to the fuselage. Lengths of .005 acupuncture needles were added as the wire, lending an additional degree of rigidity. The machine guns were added before the upper wing, as were short lengths of Mini World’s ammunition belts, which feed into the guns’ receivers.

Once these were added and the fuselage struts were in place, adding the top wing was a breeze – positive locating holes in the wing fit the struts and all was good. The wheels’ hubs were painted and masked with Eduard’s included masks, and the gray tires were airbrushed next (a lack of lampblack in Germany during WWI resulted in pale gray tires). Once dry, the wheels were added to the landing gear.

I added the crossed bracing wires between the fuselage and upper wing with trimmed acupuncture needles and painted the padding around the cockpit opening with ModelMaster leather paint, applied with a fine brush. There’s a small instrument between the guns on the fuselage for which Eduard provides a decal – I added this now and placed a drop of Future on it as the lens.

 

The rudder was joined to the tail, and I used the kit’s photoetched parts to replicate the control horns and wires, adding them by using Testors Dullcote as an adhesive. To do this, I brushed a bit of Dullcote on an index card, then, gripping the part in some tweezers, I dragged the part through the puddle of Dullcote and immediately stuck it on the model. The Dullcote has the advantage of drying very tight against the surface while still gripping the part well.

Note the control horns on the upper wings’ ailerons.

The wing control horns came next, followed the addition of the engine, the cowling, and the propeller. The cowling was cemented to the fuselage, while the propeller was glued to the engine. The engine was not cemented in place, so the prop and engine could spin together inside the cowling just like the real plane.

 

Next came some wooden elements – the tail skid, wing tip skids and fuselage foot step. The photoetched ground handling loops were added to the rear fuselage and painted black in situ.

 

Just like that, I had a neat, clean little triplane ready for our local contest. I proudly marched in with a couple of entries in hand and, just as I reached the right table, the triplane’s box slipped off the stack, did a 180-degree flip, and smacked into the ground upside down with a sickening thud, with predictable results. I spent the next two hours at a friend’s vendor table with glue and tweezers, swearing a blue streak as I re-attached the rudder and top wing, control horns, tail skid, and host of other little things. Luckily all the parts could be located inside the box. While my repairs were a bit ham-fisted, I still managed to get second place in “biplanes/fabric and rigging.”

 

Since other projects I was working on were more complex, this would be the only model I’d be bringing to the nationals, and in the condition it was in it had little chance of faring well. I decided it would look better – and maybe perform better at the contest – as the centerpiece of a simple diorama.

 

The photo of Jacobs that comes up most often is a posed shot showing him holding his dog, a Grand Bleu de Gascogne, in front of his fighter. If there’s a photograph, there must have been a photographer, so there was the idea for a diorama.

I started with a four-by-four base with a clear cover – I fear for my WWI builds!  – which was just large enough for the tiny Dr.I with space for the figures. The base was covered with white glue and then sprinkled with Woodland Scenics turf for a very simple setting for the scene.

 

The figures were next. Jacobs came from a CMK WWI pilots set, but I lopped off his head, repositioned his arms, and modified his tunic. It would figure that in the photo, he was wearing non-standard gear. I sanded back the visor and his cap, and removed the detail from his tunic, replacing it with pockets made from paper and CA-glued to the figure. The head was sourced from a W+D set. He also received a walking stick. The figure was painted using light blues for the uniform and leather for the boots, all sourced from the ModelMaster line.

W+D head, CMK body, and custom Clothing by Chris results in a pretty unattractive figure…

…Until it’s primed and starts to look usable.

Painted, Jacobs stats to look the part…

A walking stick was made from a length of metal rod and painted a pale wood color. All that was left to complete a little ace was his dog. Dogs in 1:72 are much harder to find than you’d think, especially Grand Bleu de Gascognes. My stash happened to include Pegasus’ 1:72 farm animal set, and it had a German shepherd, so I set about on my first-ever dog conversion project.

 

First, a lot of flash was cut off the soft-plastic dog figure. The shepherd’s alert, bushy tail was removed and replaced with a skinny one made of wire. The shepherd’s point ears were bobbed and I made a set of floppy replacements from Apoxie Sculpt, then draped it over the dog’s head and blended it in. After the dog was primed, it was painted black with white legs, belly and snout to approximate the photo. When it was finished, I added a collar and a thin wire leash that would attach to Jacobs’ hand.

 

Now, I needed a photographer – otherwise, it would be a diorama of a guy walking his dog near an airplane. The camera would come first. I found a nice 1:32 WWI photographer figure and copied the style of camera and tripod, replicating it with styrene strip and rod. A rectangular piece became the camera body and was painted in wood tones. The lens was a bit of .040 rod, painted black and glued to the front. A photoetched trim wheel was painted and added to the side. The tripod was made from several pieces of thin rod, with each leg having a single base that was attached to two parallel rods which attached to a mount at the base of the camera. It took some work to get all three legs the same length, but when they were all aligned, I painted them black and the camera was almost finished.

 

The photographer was a mash-up of different Prieser figures. The body and arms came from a WWII Luftwaffe pilot who was doing some “hand flying;” his epaulets and decorations were sanded away to de-militarize him, and he received a gray coat and a blue jacket. His left arm was positioned as if he was gesturing to his subject to stay still and wait for him to take the photo. In his right hand, I placed a styrene rod “trigger” attached by fine solder to the camera – the shutter release mechanism.

100 years later, you could just take the picture with your phone.

 

To make the photographer truly civilian, I grabbed one of the extra heads from Prieser’s 1920s civilian aircraft figure set. This head was wearing a cap and looked “period” but clearly not military, which is what I was going for.

 

The figures and plane were addd to the base, and with that my ridiculously simple diorama was complete. I was lucky – the model took a third at the IPMS Nationals in Omaha in small composition diorama!
