Fokker DR-1 (Lola!) From The Great Waldo Pepper.

Here are some images of Revells 1/28 scale Fokker DR.1 in the markings of LOLA! flown by the fictional Character Ernst Kessler (Udet?) excellently portrayed by Bo Brundin from the Movie "The Great Waldo Pepper" 1975.
To make this model into LOLA! I not only had to create my own decals but I had to scratch out a new tail skid, take out the front section of the cowling as well as extend it by 1/4 inch. The checker board and stripe patterns are mask painted.
The literal Translation of "Du doch nicht!!"  is "Not You!!" but it has more meaning to it. Imagine saying "not you" with a smirk and a laugh. Something like a "you and what army" feel to it. This saying was also on the stabilizer of Ernst Udet's aircraft during World War One.
As far as movies go "The Great Waldo Pepper" is a good movie. Not great, but good. However when one is a 10 year old boy it becomes one of the greatest movies ever.
I hope to make more models from this movie in the future.

From Wikipedia"
The Great Waldo Pepper is a 1975 American drama film directed, produced, and co-written by George Roy Hill. Set during 1926–1931, the film stars Robert Redford as a disaffected World War I veteran pilot who missed the opportunity to fly in combat, and examines his sense of postwar dislocation in 1920s America. The cast also includes Margot Kidder, Bo Svenson, Edward Herrmann and Susan Sarandon. The Great Waldo Pepper basically depicts barnstorming activity in the 1920s and the accidents that led to aviation regulations by the Air Commerce Act.

World War I veteran Waldo Pepper (Robert Redford) feels he has missed out on the glory of aerial combat after being made a flight instructor. After the war, Waldo had taken up barnstorming to make a living. He soon tangles with rival barnstormer (and fellow war veteran) Axel Olsson (Bo Svenson).
Antagonistic at first, Waldo and Axel become partners and try out various stunts. One of these stunts, a car-to-aircraft transfer, goes wrong and Waldo is nearly killed after Axel is unable to climb high enough to clear a barn, slamming Waldo into it. Waldo then goes home to Kansas to be with on-again, off-again girlfriend Maude (Kidder) and her family. Maude, however, is not happy to see Waldo at first; because every time he returns from a barnstorming tour of the country, he is injured in some way. Eventually, however, they make up and become lovers once again. Meanwhile, Maude's brother Ezra (Ed Herrmann), a long-time friend of Waldo's since boyhood, promises to build Waldo a high-performance monoplane as soon as he is well enough to fly it. Waldo's goal is to become the first pilot in history to successfully perform an outside loop, and Ezra feels Waldo can do it with the monoplane.
In the meantime, Waldo rejoins Axel. The two eventually get a job flying for a traveling flying circus owned by Doc Dillhoefer (Philip Bruns). However, Dillhoefer's Flying Circus is in a slump, as there is very little attendance at the shows. So in an effort to attract bigger crowds, Dillhoefer hires Mary Beth (Susan Sarandon) to act as the show's new sexual attraction, in which she would climb out on the wing of an aircraft in flight wearing shredded clothes, thus allowing the wind to blow them off. But while performing this new stunt for the first time, Mary Beth freezes up on the wing, afraid to return to the cockpit. As Waldo (who did a "plane-to-plane transfer" in flight to climb aboard Mary Beth's aircraft) extends his hand to help Mary Beth back into the cockpit, she slips and falls off the wing to her death. As a result of Mary Beth's death, Waldo, Axel, and Dillhoefer are temporarily grounded by an inspector of the newly formed Air Commerce division of the federal government, Newt Potts (Geoffrey Lewis), a man from Waldo's wartime past.
Soon after, at the Muncie Fair, another tragedy occurs with the Dillhoefer Circus when Ezra (flying in place of the grounded Waldo) attempts the outside loop in the monoplane. He crashes on his third attempt, and the crowd rushes out of the stands to see the wreckage. Some of the spectators are smoking as they watch Waldo struggle to free Ezra. One of the cigarettes is flicked into gas leaking from the aircraft, igniting it. Waldo, helpless against the flames, kills Ezra with a piece of lumber. Because no one helped Waldo try to save him, Waldo goes on a rampage, jumps in one of Dillhoefer's aircraft and begins buzzing the crowd away from the wreckage and ends up crashing into a carnival area, which leads to his permanent grounding.
But that does not stop Waldo from flying for long. Waldo goes to Hollywood where Axel is working as a stuntman, and Waldo and Axel get jobs as stunt pilots in an upcoming film depicting the air battles of the Great War. Axel is cleared of his grounding and reinstated as a pilot; but being permanently grounded, Waldo has to use an alias so that he can dodge his grounding and fly in the film. Famous German air ace Ernst Kessler (Bo Brundin) has also been hired by the producers, as a consultant and to fly a Fokker Dr. I replica in the film.
During filming of a famous wartime duel, Waldo in a Sopwith Camel and Kessler in the Fokker—although their aircraft are disarmed—begin dogfighting in deadly earnest, using their aircraft as weapons, repeatedly playing chicken and colliding with each other. Eventually, Waldo damages Kessler's aircraft so badly that it's no longer airworthy, and Kessler surrenders to Waldo. Waldo and Kessler then salute each other and fly their separate ways.
The Great Waldo Pepper was a "passion project" for director George Roy Hill, who was himself a pilot. He and William Goldman had what Goldman described as "a huge falling out" during the middle of Goldman's writing the screenplay. Nevertheless, they managed to complete the project.
Frank Tallman flew the air sequences using actual aircraft – not models. Waldo flew a Standard J-1 biplane. A lot of the other aircraft in the film, including Axel's and those of Dillhoefer's, were Curtiss JN-4 biplanes. A number of de Havilland Tiger Moth biplanes, modified to look like Curtiss JN-4s, were used for the crash scenes.
The Great Waldo Pepper was filmed in Elgin, Texas. Aerial sequences were filmed at Zuehl Airfield near San Antonio, which is not too far from Fort Sam Houston, where the pioneering silent aviation classic Wings was shot in 1926-27. Several aerial scenes were also filmed over the Sebring, Florida, Airport (also known for the 12 Hours of Sebring, a Le Mans-style endurance car race). Hill, who flew as a U.S. Marine Corps cargo pilot in World War II, made sure stars Bo Svenson and Robert Redford did each sequence with no parachutes or safety harnesses. He wanted them to feel what it was like to fly vintage aircraft. Fortunately, no one was hurt during the air scenes.

The Great Waldo Pepper opened to mixed to good reviews, with the biggest praise going to the film's aerial sequences. Vincent Canby of The New York Times wrote, "'The Great Waldo Pepper' is a most appealing movie. Its moods don't quite mesh and its aerial sequences are so vivid— sometimes literally breathtaking— that they upstage the human drama, but the total effect is healthily romantic." Leonard Maltin noted that the film disappointed at the box office, and, although compared to earlier efforts such as The Sting (1973), it was director George Roy Hill's "more personal" account that "... wavers uncomfortably between slapstick and drama."
The aerial sequences staged by Frank Tallman included the climactic fight between Waldo Pepper and Kessler. The scene featuring a replica Sopwith Camel and a replica Fokker Triplane, was loosely patterned after a real dogfight between German ace Werner Voss and a flight of aircraft led by British ace James McCudden.
Due to the attention to period details and the use of actual aircraft in the flying scenes, The Great Waldo Pepper is well-regarded among aviation films, receiving a "four-star" rating by film and aviation historians Jack Hardwick and Ed Schnepf. Released in a number of home media formats, there are no extra features in the latest DVD.
Former silent screen actress Viola Dana was an honored guest at the premiere of The Great Waldo Pepper. In 1920, Dana had begun a relationship with Ormer "Lock" Locklear, a daring aviator, military veteran and budding film star, reputed to be the prototype for the character of Waldo Pepper. Locklear died when his aircraft crashed on August 2, 1920 during a nighttime film shoot for the Fox Studios feature, The Skywayman.

Fokker D. VI

Here are some images of Roden's 1/32 scale Fokker D. VI.

From Wikipedia"

The Fokker D.VI was a German fighter aircraft built in limited numbers at the end of World War I. The D.VI served in the German and Austro-Hungarian air services.


In late 1917, Fokker-Flugzeugwerke built two small biplane prototypes designated V.13. These aircraft combined a set of scaled-down D.VII wings with a fuselage and empennage closely mirroring those of the earlier Dr.I. The first prototype utilized an 82 kW (110 hp) Oberursel Ur.II rotary engine, while the second featured a 119 kW (160 hp) Siemens-Halske Sh.III bi-rotary engine.
Fokker submitted both prototypes at the Adlershof fighter trials in late January 1918. At that time, Fokker reengined the first prototype with the 108 kW (145 hp) Oberursel Ur.III. Pilots found the V.13s to be maneuverable and easy to fly. Idflieg issued a production contract after the V.13s were ultimately judged to be the best rotary powered entries of the competition.


The new aircraft, designated D.VI, passed its Typenprüfung (official type test) on 15 March 1918. The production aircraft utilized the Oberursel Ur.II, which was the only readily available German rotary engine. Idflieg authorized low level production pending availability of the more powerful Goebel Goe.III. Deliveries commenced in April and ceased in August, after only 59 aircraft had been completed. Seven aircraft were delivered to the Austro-Hungarian Air Service (Luftfahrtruppen).
In service, the D.VI was hampered by the low power of the Oberursel Ur.II. Moreover, the lack of castor oil and the poor quality of "Voltol," an ersatz lubricant, severely reduced engine life and reliability. The D.VI remained in frontline service until September 1918, and continued to serve in training and home defense units until the Armistice.

Jeannin Stahltaube 1914

Here are some images of Wingnut Wings 1/32 scale Jeannin Stahltaube 1914.

From Wikipedia"
The Etrich Taube, also known by the names of the various later manufacturers who build versions of the type, such as the Rumpler Taube, was a pre-World War I monoplane aircraft. It was the first military aeroplane to be mass-produced in Germany.
The Taube was very popular prior to the First World War, and it was also used by the air forces of Italy and Austria-Hungary. Even the Royal Flying Corps operated at least one Taube in 1912. On November 1, 1911, Giulio Gavotti, an Italian aviator, dropped the world's first aerial bomb from his Taube monoplane over the Ain Zara oasis in Libya. Once the war began, it quickly proved inferior as a serious warplane and as a result was soon replaced by newer and more effective designs.

The Taube was designed in 1909 by Igo Etrich of Austria-Hungary, and first flew in 1910. It was licensed for serial production by Lohner-Werke in Austria and by Edmund Rumpler in Germany, now called the Etrich-Rumpler-Taube. Rumpler soon changed the name to Rumpler-Taube, and stopped paying royalties to Etrich, who subsequently abandoned his patent.
Despite its name, the Taube's unique wing form was not modeled after a dove, but was copied from the seeds of Alsomitra macrocarpa, which can fly long distances from their parent tree. Similar wing shapes were also used by Karl Jatho and Frederick Handley Page. Etrich had tried to build a flying wing aircraft based on the Zanonia wing shape, but the more conventional Taube type, with tail surfaces, was much more successful.
Etrich adopted the format of crosswind-capable main landing gear that Louis Blériot had used on his Blériot XI cross-channel monoplane for better ground handling. The wing has three spars and was braced by a cable-braced steel tube truss (called a "bridge", or Brücke in German) under each wing: at the outer end the uprights of this structure were lengthened to rise above the upper wing surfaces, to form kingposts to carry bracing and warping wires for the enlarged wingtips. A small landing wheel was sometimes mounted on the lower end of this kingpost, to protect it for landings and to help guard against ground loops.
Later Taube-type aircraft from other manufacturers would eventually replace the Blériot-style crosswind main gear with a simpler V-strut main gear format, and also omitted the underwing "bridge" structure for somewhat better aerodynamic efficiency.
Like many contemporary aircraft, especially monoplanes, the Taube used wing warping rather than ailerons for lateral (roll) control, and also warped the rear half of the stabilizer for use as an elevator control surface's function. Only the vertical, twinned triangular rudder surfaces were usually hinged.

The design provided for very stable flight, which made it extremely suitable for observation. In addition, the translucent wings made it difficult for ground observers to detect a Taube at an altitude above 400 meters. The first hostile engagement was by an Italian Taube in 1911 in Libya, its pilot using pistols and dropping 2 kg (4.4 lb) grenades. The Taube was also used for bombing in the Balkans in 1912–13, and in late 1914 when German 3 kg (6.6 lb) bomblets and propaganda leaflets were dropped over Paris. Taube spotter planes detected the advancing Imperial Russian Army in East Prussia during the World War I Battle of Tannenberg.
In civilian use, the Taube was used by pilots to win the Munich-Berlin Kathreiner prize. On 8 December 1911, Gino Linnekogel and Suvelick Johannisthal achieved a two-man endurance record for flying a Taube 4 hours and 35 minutes over Germany.
While initially there were two Taube aircraft assigned to Imperial German units stationed at Qingdao, China only one was available at the start of the war due to an accident. The Rumpler Taube piloted by Lieutenant Gunther Plüschow had to face the attacking Japanese, who had with them a total of eight aircraft. On October 2, 1914, Plüschow's Taube attacked the Japanese warshipswith two small bombs, but failed to score any hits. On November 7, 1914, shortly before the fall of Qingdao, Plüschow was ordered to fly top secret documents to Shanghai, but was forced to make an emergency landing at Lianyungang in Jiangsu, where he was interned by a local Chinese force. Plüschow was rescued by local Chinese civilians under the direction of an American missionary, and successfully reached his destination at Shanghai with his top secret documents, after giving the engine to one of the Chinese civilians who rescued him.
Poor rudder and lateral control made the Taube difficult and slow to turn. The aeroplane proved to be a very easy target for the faster and more mobile Allied fighters of World War I, and just six months into the war, the Taube had been removed from front line service to be used to train new pilots. Many future German aces would learn to fly in a Rumpler Taube.Due to the lack of license fees, no less than 14 companies built a large number of variations of the initial design, making it difficult for historians to determine the exact manufacturer based on historical photographs. 

The Technisches Museum Wien is thought to have the only known remaining Etrich-built example of the Taube in existence, an early enough example to have a four-cylinder engine powering it, and is potentially a twin to Gavotti's Taube aircraft from 1911, also said to have been powered with a four-cylinder inline engine. Other examples of original Taubes exist, such as one in Norway, which was the last original Taube to fly under its own power in 1922, over a Norwegian fjord.
The Owl's Head Transportation Museum in Owls Head, Maine USA, is so far the only known museum to attempt the construction of a flyable reproduction of the Etrich Taube in North America. Their example first flew in 1990, and it still flies today with the power of a 200 hp Ranger L-440 inline-6 "uprighted" air-cooled engine.

Fokker E.V/D.VIII

Here are some images of Mir Models 1/32 scale Fokker E.V/D.VIII. This aircraft was flown by Ltn.Z.See Gotthard Sachseberg, Marine Field Jagdgruppe I, Flandern, Coolkerke Airfield. August 1918.

From Wikipedia"
The Fokker E.V was a German parasol-monoplane fighter aircraft designed by Reinhold Platz and built by Fokker-Flugzeugwerke. The E.V was the last Fokker design to become operational with the Luftstreitkräfte, entering service in the last months of World War I. After several fatal accidents due to wing failures, the aircraft was modified and redesignated Fokker D.VIII. Dubbed the Flying Razor by Allied pilots, the D.VIII had the distinction of scoring the last aerial victory of the war.

In early 1918, Fokker produced several rotary-powered monoplane prototypes. Of these, Fokker submitted the V.26 and V.28, small parasol-winged monoplanes with his usual steel-tube fuselages, for the second fighter trials at Adlershof in May/June 1918. The V.28 was tested with both the 108 kW (145 hp) Oberursel UR.III and 119 kW (160 hp) Goebel Goe.III, though neither of these engines were ready for operational service. The V.26 utilized the standard Oberursel UR.II engine, producing only 82 kW (110 hp). While this engine was obsolete, the V.26's low drag and light weight meant that it was nevertheless quite fast. The Fokker designs were only barely beaten by the Siemens-Schuckert D.III with the complex bi-rotary Siemens-Halske Sh.III engine.
In the end, the V.26 was ordered into production as the Fokker E.V. Four hundred were ordered immediately with either the UR.III or Goe.III. Because neither engine was available in any quantity, all production examples mounted the UR.II.

The first production E.V aircraft were shipped to Jasta 6 in late July. The new monoplane was also delivered to Jasta 1, Jasta 19, Jasta 24 and Jasta 36. Leutnant Emil Rolff scored the first kill in an E.V on August 17, 1918, but two days later he was killed when his aircraft's wing collapsed in flight. After another E.V of Jasta 19 crashed, Idflieg grounded all E.V aircraft. Pending the investigation of these wing failures, production ceased at the Fokker Flugzeugwerke. According to Fokker, the wing failures were caused by the army technical bureau, which had forced him to modify the original design by over-strengthening the rear main spar. This faulty design allegedly caused the wing to twist and fail. Fokker claimed that this defect was resolved by reverting to his original design.
According to most other accounts, the source of the wing failures lay not in the design, but in shoddy and rushed construction. Fokker had subcontracted construction of the E.V wings to the Gebrüder Perzina Pianoforte Fabrik factory. Due to poor quality control, inferior timber had been used and the spar "caps", forming the upper and lower members of each spar assembly, had been placed too far apart during the fabrication. Because the resulting spars were vertically too large to pass through the ribs, excess material was simply planed away from the exposed upper and lower surfaces of the cap pieces, leaving the assembled spars dangerously weak. Other problems included water damage to glued parts, and pins that splintered the spars, rather than securing them.[1]
Tests showed that, when properly constructed, the original E.V wing had a considerable margin of safety. Satisfied that the basic design was safe, Idflieg authorized continued production, after personnel changes and improved quality control measures were introduced at the Perzina factory.
Deliveries resumed in October. At the direction of the Kogenluft (Kommandierenden General der Luftstreitkräfte), Idflieg redesignated the modified aircraft D.VIII. Henceforth, the "E." and "Dr." designations were abolished and all fighters received the "D." appellation. The D.VIII commenced operations on 24 October with Jasta 11. The aircraft proved to be agile and easy to fly. Allied pilots nicknamed it the Flying Razor, because of its sleek appearance and single wing.
Jasta 5 was issued a D.VIII. The famed ace Erich Lowenhardt used the aircraft for a short time and scored a few victories in it, but he continued to favour the Fokker D.VII.
A total of 381 aircraft were produced, but only some 85 aircraft reached frontline service before the Armistice. Some reached Italy, Japan, the United States, and England as trophies, but most were scrapped in accordance with the terms of the Armistice.

Postwar

The Polish Air Force captured 17 aircraft, but only seven (six E.V and one D.VIII) were in airworthy condition. All were used against Soviet forces in the Polish-Soviet War of 1919-1920. Lieutenant Stefan Stec earned the first kill for the Polish Air Force, by shooting down a Ukrainian Nieuport fighter on 29 April 1919. In 1921, the remaining Fokkers were withdrawn from front-line units and transferred to the Szkoła Obsługi Lotniczej (Air Personnel School) at Poznań-Ławica airfield.

Fokker E.III Eindecker

Here are some images of Wingnut Wings 1/32 scale Fokker E.III Eindecker.

From Wikipedia"
The Fokker Eindecker fighters were a series of German World War I monoplane single-seat fighter aircraft designed by Dutch engineer Anthony Fokker. Developed in April 1915, the first Eindecker ("Monoplane") was the first purpose-built German fighter aircraft and the first aircraft to be fitted with a synchronization gear, enabling the pilot to fire a machine gun through the arc of the propeller without striking the blades. The Eindecker gave the German Air Service a degree of air superiority from July 1915 until early 1916. This period, during which Allied aviators regarded their poorly armed aircraft as "Fokker Fodder", became known as the "Fokker Scourge".
 The Eindecker was based on Fokker's unarmed Fokker M.5K scout (military designation Fokker A.III) which imitated the design of the French Morane-Saulnier H shoulder-wing monoplane, but using chrome-molybdenum steel tubing for the fuselage structure instead of wood. It was fitted with an early version of the Fokker synchronizer mechanism controlling a single Parabellum MG14 machine gun. Anthony Fokker personally demonstrated the system on 23 May 1915, having towed the prototype aircraft behind his touring car to a military airfield near Berlin.

The E.III was basically an E.II fitted with larger, newly designed wings that had a slightly narrower chord of 1.80 meter (70-7/8 in), compared to 1.88 meter (74 in) on the earlier Eindeckers, going back to Fokker's original M.5 monoplane aircraft. The E.III retained the same 75 kW (100 hp) Oberursel U.I engine, and therefore also used the larger diameter "horseshoe" pattern cowling that also mandated the inclusion of the E.II's soffit-like extensions to the sides of the upper nose sheet metalwork, but had a larger 81 l (21.5 gal) drum-shaped main fuel tank just behind the cockpit, which increased the Eindecker's endurance to about 2½ hours; an hour more than the E.II. Most E.IIIs were armed with a single 7.92 mm (.312 in) Spandau LMG 08 machine gun with 500 rounds of ammunition; however, after the failure of the twin-gun Fokker E.IV as a viable successor, some E.IIIs were fitted with twin guns.
Fokker production figures state that 249 E.IIIs were manufactured; however, a number of the 49 E.IIs were upgraded to E.III standard when they were returned to Fokker's Schwerin factory for repairs.

The E.III was the first type to arrive in sufficient numbers to form small specialist fighter units, Kampfeinsitzer Kommandos (KEK) in early 1916. Previously, Eindeckers had been allocated singly, just as the E.I and E.II had been, to the front-line Feldflieger Abteilungen that carried out reconnaissance duties. On 10 August 1916, the first German Jagdstaffeln (single-seat fighter squadrons) were formed, initially equipped with various early fighter types, including a few E.IIIs, which were by then outmoded and being replaced by more modern fighters. Standardisation in the Jagdstaffeln (and any real success) had to wait for the availability in numbers of the Albatros D.I and Albatros D.II in early 1917.
Turkish E.IIIs were based at Beersheba in Palestine while others operated in Mesopotamia during the Siege of Kut-al-Amara.
 The only known surviving original Eindecker, bearing IdFlieg serial number 210/16, was brought down in the Somme area in 1916 by the British and then evaluated by the War Office until it was transferred to the London Science Museum in 1918. It is currently on display fully assembled, but with its fabric covering removed to illustrate its internal construction.

Fokker D.VII

Here are some images of Revell's 1/28 scale Fokker D. VII.

From Wikipedia"
The Fokker D.VII was a German World War I fighter aircraft designed by Reinhold Platz of the Fokker-Flugzeugwerke. Germany produced around 3,300 D.VII aircraft in the second half of 1918. In service with the Luftstreitkräfte, the D.VII quickly proved itself to be a formidable aircraft. The Armistice ending the war specifically required Germany to surrender all D.VIIs to the Allies. Surviving aircraft saw continued widespread service with many other countries in the years after World War I.

Fokker's chief designer, Reinhold Platz, had been working on a series of experimental planes, the V-series, since 1916. These aircraft were characterized by the use of cantilever wings. Junkers had originated the idea in 1915 with the first all-metal aircraft, the Junkers J 1, nicknamed Blechesel ("Sheet Metal Donkey" or "Tin Donkey"). The resulting wings were thick, with a rounded leading edge. This gave greater lift and more docile stalling behavior than the thin wings commonly used at the time.
Late in 1917, Fokker built the experimental V 11 biplane, fitted with the standard Mercedes D.IIIa engine. In January 1918, Idflieg held a fighter competition at Adlershof. For the first time, frontline pilots would directly participate in the evaluation and selection of new fighters. Fokker submitted the V 11 along with several other prototypes. Manfred von Richthofen flew the V 11 and found it tricky, unpleasant, and directionally unstable in a dive. In response to these complaints, Reinhold Platz lengthened the rear fuselage by one structural bay, and added a triangular vertical fin in front of the rudder. Upon flying the modified V 11, Richthofen praised it as the best aircraft of the competition. It offered excellent performance from the outdated Mercedes engine, yet was safe and easy to fly. Richthofen's recommendation virtually decided the competition, but he was not alone in recommending it. Fokker immediately received a provisional order for 400 production aircraft, which were designated D.VII by Idflieg.
Fokker's factory was not up to the task of meeting all D.VII production orders. Idflieg therefore directed Albatros and AEG to build the D.VII under license, though AEG did not ultimately produce any aircraft. Because the Fokker factory did not use detailed plans as part of its production process, Fokker simply sent a completed D.VII airframe for Albatros to copy. Albatros paid Fokker a five percent royalty for every D.VII built under license. Albatros Flugzeugwerke and its subsidiary, Ostdeutsche Albatros Werke (OAW), built the D.VII at factories in Johannisthal (designated Fokker D.VII (Alb)) and Schneidemühl (Fokker D.VII (OAW)), respectively. Aircraft markings included the type designation and factory suffix, immediately before the individual serial number.
Some parts were not interchangeable between aircraft produced at different factories, even between Albatros and OAW. Additionally each manufacturer tended to differ in nose paint styles. OAW produced examples were delivered with distinctive mauve and green splotches on the cowling. All D.VIIs were produced with either the five-color Fünffarbiger five-color, or less often the four-color Vierfarbiger lozenge camouflage covering except for early Fokker-produced D.VIIs, which had a streaked green fuselage. Factory camouflage finishes were often overpainted with colorful paint schemes or insignia for the Jasta, or the individual pilot.
In September 1918, eight D.VIIs were delivered to Bulgaria. Late in 1918, the Austro-Hungarian company MÁG (Magyar Általános Gépgyár - Hungarian General Machine Company) commenced licensed production of the D.VII with Austro-Daimler engines. Production continued after the end of the war, with as many as 50 aircraft completed.

Many sources erroneously state that the D.VII was equipped with the 120 kW (160 hp) Mercedes D.III engine. The Germans themselves used the generic D.III designation to describe later versions of that engine. The earliest production D.VIIs were equipped with 170-180 hp Mercedes D.IIIa. Production quickly switched to the intended standard engine, the higher-compression 134 kW (180-200 hp) Mercedes D.IIIaü. It appears that some early production D.VIIs delivered with the Mercedes D.IIIa were later re-engined with the D.IIIaü.
By mid-1918, some D.VIIs received the "overcompressed" 138 kW (185 hp) BMW IIIa, the first product of the BMW firm. The BMW IIIa followed the SOHC, straight-six configuration of the Mercedes D.III, but incorporated several improvements. Increased displacement, higher compression, and an altitude-adjusting carburetor produced a marked increase in speed and climb rate at high altitude. Because the BMW IIIa was overcompressed, using full throttle at altitudes below 2,000 m (6,700 ft) risked premature detonation in the cylinders and damage to the engine. At low altitudes, full throttle could produce up to 179 kW (240 hp) for a short time. Fokker-built aircraft with the new BMW engine were designated D.VII(F), the suffix "F" standing for Max Friz, the engine's designer.
BMW-engined aircraft entered service with Jasta 11 in late June 1918. Pilots clamored for the D.VII(F), of which about 750 were built. Production of the BMW IIIa was very limited and the D.VII continued to be produced with the 134 kW (180 hp) Mercedes D.IIIaü until the end of the war.
D.VIIs flew with different propeller designs from different manufacturers. Despite the differing appearances there is no indication these propellers gave disparate performance. Axial, Wolff, Wotan, and Heine propellers have been noted.
The D.VII entered squadron service with Jasta 10 in early May 1918. When the Fokker D.VII appeared on the Western Front in April 1918, Allied pilots at first underestimated the new fighter because of its squarish, ungainly appearance, but quickly revised their view. The type quickly proved to have many important advantages over the Albatros and Pfalz scouts. Unlike the Albatros scouts, the D.VII could dive without any fear of structural failure. The D.VII was also noted for its high maneuverability and ability to climb at high angles of attack, its remarkably docile stall, and its reluctance to spin. It could literally "hang on its prop" without stalling for brief periods of time, spraying enemy aircraft from below with machine gun fire. These handling characteristics contrasted with contemporary scouts such as the Camel and SPAD, which stalled sharply and spun vigorously.
The D.VII also had problems. Several aircraft suffered rib failures and fabric shedding on the upper wing. Heat from the engine sometimes ignited phosphorus ammunition until cooling vents were installed in the engine cowling, and fuel tanks sometimes broke at the seams. Aircraft built by the Fokker factory at Schwerin were noted for their lower standard of workmanship and materials. Nevertheless, the D.VII proved to be a remarkably successful design, leading to the familiar aphorism that it could turn a mediocre pilot into a good one, and a good pilot into an ace.
Manfred von Richthofen died days before the D.VII began to reach the Jagdstaffeln and never flew it in combat. Other pilots, including Erich Löwenhardt and Hermann Göring, quickly racked up victories and generally lauded the design. Aircraft availability was limited at first, but by July there were 407 in service. Larger numbers became available by August, when D.VIIs achieved 565 victories. The D.VII eventually equipped 46 Jagdstaffeln. When the war ended in November, 775 D.VII aircraft were in service.

The Allies confiscated large numbers of D.VII aircraft after the Armistice. The United States Army and Navy evaluated 142 captured examples. Several of these aircraft were re-engined with American-built Liberty L-6 motors, very similar in appearance to the D.VII's original German power plants. France, Great Britain, and Canada also received numbers of war prizes.
Other countries used the D.VII operationally. The Polish deployed approximately 50 aircraft during the Polish-Soviet War, using them mainly for ground attack missions. The Hungarian Soviet Republic used a number of D.VIIs, both built by MAG and ex-German aircraft in the Hungarian-Romanian War of 1919.
The Dutch, Swiss, and Belgian air forces also operated the D.VII. The aircraft proved so popular that Fokker completed and sold a large number of D.VII airframes that he had smuggled into the Netherlands after the Armistice. As late as 1929, the Alfred Comte company manufactured eight new D.VII airframes under license for the Swiss Fliegertruppe.

DFW T-28 Floh (Flea)

Here are some images of Planet Models 1/32 scale DFW T-28 Floh (Flea).

From Wikipedia.

The DFW T.28 Floh (English: Flea) was a small German biplane fighter prototype designed by Hermann Dorner, the designer of the successful Hannover CL.II two-seat fighter of 1917, and built by Deutsche Flugzeug-Werke. Designed in 1915 as high-speed fighter the Floh had a small 6.20 m (20.3 ft) wingspan and a rather ungainly tall and thin fuselage.[1] With a fixed conventional landing gear the Floh was powered by a 100 hp (75 kW) Mercedes D.I inline piston engine, and on its first fight in December 1915 reached 180 km/h, quite fast for the time.The aircraft suffered from very poor forward visibility and was difficult to land due to its narrow landing gear.The prototype crashed during the flight testing programme.
