Dornier Do 335B-2 (Dragon Models)

TYPE: Destoyer, Fighter-bomber


POWER PLANT: Two Daimler-Benz DB 603E-1 liquid-cooled engines, rated at 1,900 hp at 5,905 ft each

PERFORMANCE: 474 mph at 22,000 ft

COMMENT: The Dornier Do 335 „Pfeil“ (Arrow) was a German World-War II heavy fighter built by the Dornier company. The Pfeil’s performance was much better than other twin-engine designs due to its unique push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It was Germany’s fastest piston-engined aircraft of World War II. The Luftwaffe was desperate to get the design into operational use, but delays in engine deliveries meant that only a handful were delivered before the war ended.
The first 10 Do 335A-0s were delivered for testing in May 1944. By late this year, the Do 335A-1 was on the production line. It was similar to the A-0 but with the uprated DB 603E-1 engines of some 1,800 hp take-off power rating apiece and two underwing hardpoints for additional bombs, drop tanks or guns. It had a maximum speed of 474 mph at 21 300 ft with MW 50 boost, or 426 mph without boost, and climbed to 26, 250 ft in under 15 minutes. Even with one engine out, it reached about 350 mph.
With the worsening of war situation development emphasis in the „Pfeil“ programme switched from the A-series fighter-bomber to the more heavily armed B-series „Zerstörer“ (Destroyer), and during the winter 1944-45 the first Do 335B prototypes were completetd at Oberpfaffenhofen. The initial B-series „Zerstörer“ were essentially similar to the Do 335A-1 apart from armament and the deletion of internal weapon bay, its space being utilized by a supplement fuel tank. The Do 335 V13 had a 15-mm MG 151 cannon in the forward fuselage replaced by 20-mm MG 151s, and was intended to serve as a prototype fort he Do 335B-1, and the Do 335 V14 had this armament supplemented by two 30-mm MK 103 cannon mounted just inboard oft he main undercarriage attachment points, this being the prototype fort he Do 335B-2.
These were destined to be the only B-series prototypes actually completed and flown, although six additional aircraft were under construction at Oberpfaffenhofen when further development was terminated. These were the Do 335 V15 and V16, respectively the second prototype oft he B-1 and B-2 models, the Do 335 V17 which was intended  as a prototype oft he  B-6 two-seat night and bad weather fighter similar to the Do 335 A-6 but posessing the same armament as that oft he B-1; The Do 335 V18 which was to have been the second prototype fort he Do 335B-6, and the  Do 335 V19 and V20 which would have been respectively  prototypes  for the Do 335B-3 and B-7 powered by DB 603LA engines with two stage superchargers, the former being a single-seater similar to the B-2 and the latter being a two-seater similar tot he B-6 (Ref.: 7, 24).

Heinkel He 119 A-0 (V6), (Valom Models)

TYPE: Reconnaissance bomber

ACCOMMODATION: Crew of three

POWER PLANT: One Daimler-Benz DB 606A-2, twenty-four-cylinder liquid-cooled coupled engine, rated at 2,350 hp

PERFORMANCE: 367 mph at 14,755 ft

COMMENT: The Heinkel He 119 was an experimental single-propeller monoplane with two coupled engines, developed in Germany. A private venture by Heinkel to test radical ideas by the Günter brothers, the He 119 was originally intended to act as an unarmed reconnaissance bomber capable of eluding all fighters due to its high performance.
Design was begun in the late summer of 1936. A notable feature of the aircraft was the streamlined fuselage, most likely as an evolutionary descendant of the 1932-vintage Heinkel H 70 record-setting single-engined mailplane design, but without the He 70’s protruding canopy-enclosed crew accommodation existing anywhere along the exterior. Instead, the He 119’s forward fuselage featured an extensively glazed cockpit forming the nose itself, heavily framed with many diagonally braced windows immediately behind the propeller spinner’s rear edge. Two of the three-man crew sat on either side of the driveshaft, which ran aft to a “power system”, a coupled pair of Daimler-Benz DB 601 engines mounted above the wing center-section within the fuselage, mounted together within a common mount (the starboard component engine having a “mirror-image” centrifugal supercharger) with a common gear reduction unit fitted to the front ends of each component engine, forming a drive unit known as the Daimler-Benz DB 606, the first German aircraft to use the “high-power” power plant system meant to provide German aircraft with an aviation power plant design of over 2,000 PS output capability.
The DB 606 engine was installed just behind the aft cockpit wall, near the center of gravity, with an enclosed extension shaft passing through the centerline of the extensively glazed cockpit to drive a large four-blade variable-pitch airscrew in the nose. An evaporative cooling system was used on the first aircraft (V1), with the remaining prototypes receiving a semi-retractable radiator directly below the engine to augment cooling during take-off and climb.
Only eight prototypes were completed and the aircraft did not see production, mainly because of the shortages of DB 601 “component” engines to construct the 1,500 kg “power systems” they formed. The first two prototypes were built as land planes, with retractable landing gear. The third prototype (V3) was constructed as a seaplane with twin floats. This was tested at the “Erprobungsstelle Travemünde” military seaplane test facility on the Baltic coast, and was scrapped in 1942 at Heinkel’s factory airfield in the coastal Rostock-Schmarl community, then known as Marienehe.
On November 1937, the fourth prototype (V4) made a world class-record flight in which it recorded an airspeed of 314 mph, with a payload of 1,000 kg, over a distance of 1,000 km. The four remaining prototypes were completed during the spring and early summer of 1938, the V5 and V6 being A-series production prototypes for the reconnaissance model, and the V7 and V8 being B-series production prototypes for the bomber model.
These four aircraft were three-seaters with a defensive armament of one 7.92 mm MG 15 machine gun in a dorsal position, V7 and V8 having provision for a normal bombload of three 250 kg bombs or maximum bombload of 1,000 kg. V7 and V8 were sold to Japan in May 1940, and extensively studied; the insights thus gained were used in the design of the Yokosuka R2Y1 “Keiun” The remaining prototypes served as engine test-beds, flying with various prototype versions of the DB 606 and DB 610 (twinned Daimler-Benz DB 605) and the experimental DB 613 (twinned Daimler-Benz DB 603).
In 1944, a high-speed bomber development, designed as a private venture by Heinkel to test radical ideas by the Günter brothers, was the Heinkel He 519. It was designed to use the 24-cylinder Daimler-Benz DB 613, but the aircraft remained a concept and was abandoned at the end of the war. (Ref.: 24).

Blohm & Voss Ae 607 (RS Models, Resin)

TYPE: Experimental flying wing aircraft


POWER PLANT: One Heinkel-Hirth HeS 011 turbojet, rated at 1,200 kp thrust


COMMENT: The Blohm & Voss Ae 607 was a turbojet-powered flying wing design drawn up by Blohm & Voss in 1945. Very little is known about it and its existence was only confirmed end of the last century.
Early in 1945, a Blohm & Voss aircraft designer called Thieme began work on Drawing Number Ae 607 within the standard drawing numbering system at B&V and labelled it „Nurflügel-TL-Jäger“ („All-wing jet fighter“). His design for a jet fighter was radically different from anything that B&V had done before: A flying wing, it approximated to a 45° delta planform.
An all-wing design, the centre section has a V-shaped lower profile deepening its keel and is sharply tapered both front and rear, while the outer sections are sharply swept at approximately 45° and tapered, giving the leading edge a sweep greater than 45° and the trailing edge an M-shaped outline from above. The wing tips are turned down, giving them a slight anhedral.
A turbojet engine duct runs down the centre, with the Heinkel-Hirth HeS 011 engine installed towards the rear. A small tail fin is placed above the jet exhaust duct, while the pilot’s cockpit is set just in front of the engine, but still well aft, and is offset to one side to give the pilot room alongside the intake duct. It is covered by a teardrop canopy. Two small, low aspect ratio and untapered canard foreplanes sweep forward from either side of the nose intake.
The undercarriage comprises main wheels retracting outwards and twin tailwheels retracting on either side of the engine exhaust duct. On the ground, it sits with a marked nose-up attitude presumably to keep the air intake well away from any surface debris while take-off. Estimated performance as well as it’s conceptual formulation is unknown. The Blohm & Voss Ae 607 „Nurflügel-TL-Jäger“ never received a „P“ number (Project number) and was probably only intended to showcase ideas for solving particular problems facing designers when designing on a layout for fighters. The authenticity of the „Nurflügel-TL-Jäger“ has been questioned for years but, oddly enough, it has proven to be an entirely genuine wartime design (Ref.: 24).

Heinkel He P. 1078C (Frank Airmodel, Resin)

TYPE: Interceptor


POWER PLANT: One Heinkel/Hirth HeS 011 turbojet engine, rated at 1,200 kp thrust

PERFORMANCE: 480 mph at 32,800 ft

COMMENT: The Heinkel He P.1078 was a single-seat interceptor developed for the Luftwaffe by Heinkel aircraft manufacturing company under the  „Jägernotprogramm“ (Emergency Fighter Programm) during the closing stage of the Third Reich.
Germany’s Emergency Fighter Program was enacted in the middle of July in 1944 in response to the Allied bombing offensive taking out critical German war-making capabilities. The new aircraft was intended to have superior performance in order to deal with the expected high altitude threats such as the Boeing B-29 Superfortress, but only had a 30-minute endurance figure.
The high-altitude fighter designs brought forward by other German aircraft makers were the Messerschmitt Me P.1101, Focke-Wulf Ta 183 „Huckebein“, Blohm & Voss Bv P.212, and Junkers EF 128.
The Heinkel Company was a competitor, too, and offered ist He P.1078 project in three quite different variants. All of them were a single-seat fighters with polyhedral swept wings. The wings were swept back at 40 degrees and included wood in their construction. All of the projected aircraft had the wing tips angled downwards and all of them would be powered by a single Heinkel/Hirth HeS 011 turbojet.
The Heinkel He P.1078A was a turbojet-powered interceptor. It was the most conventional-looking of the three designs submitted for it was the only one having a tail. Its armament was two MK 108 cannons, as in the following two variants.
The Heinkel He P.1078B was a tailles asymmetric jet-powered interceptor with a short fuselage in which the air intake of the engine was located in the middle between two gondolas. The cockpit was located on the gondola of the left side, while the right side gondola contained the front undercarriage leg and cannon armament.
Finally the Heinkel He P.1078C was a tailless interceptor project similar to the He P.1078B but with a single short fuselage. Both the He P.1078B and He P.1078C had wing tips angled downwards at a more pronounced angle than the He P.1078A.
To keep production costs down and expedite mass production, the Heinkel He P.1078C design was relatively simple in nature, utilizing wood wherever possible. The metal fuselage sported a length no longer than 17 feet and contained the armored cockpit, armament and relatively large single engine fitting, fuel was to be housed in the wings. Wingspan was just under 30 feet and the design as a whole just topped 7 feet, 8 inches in height. The armament would have consisted of two MK 108 cannons fitted to either side of the nose section. The nose section itself was rather short and acted as the air intake to aspirate the turbojet engine buried further aft in the design. The opening was rectangular in nature and conformed well to the fuselage’s square appearance when viewed in the forward profile. The engine exhausted at the rear through a conventional exhaust ring. The cockpit was held well-forward in the design with the pilot seated under a small canopy allowing for limited viewing ahead and to the sides (the rear was obstructed by way of a short fuselage spine). The undercarriage was fully retractable and would have consisted of three landing gear legs: two main legs at amidships and a nose landing gear leg – all were single-wheeled installations. When at rest, this arrangement would have given the He P.0178C a distinct “nose-up” appearance, in effect perhaps promoting quicker take-offs with the increased wing drag at speed. Since the turbojet-powered fighter would have been operating at high altitudes, the cockpit was to be fully pressurized and equipped withan ejection seat.
Perhaps the most identifiable portion of the He P.1078Cs design was its wings. The assemblies were fitted high against the fuselage sides and extensively swept rearwards. Each wing was cranked upwards from fuselage centerline up to roughly three-quarters out and then capped with a short wing piece cranked sharply downwards. The reason for this design was largely related to aerodynamic principles that were still being researched at the time and the result was to have combated stress effects on the wings at high speeds. Ernst Heinkel was convinced of their ability to provide for increased maneuvering and agility during dogfights. It bears note that there were no horizontal tailplanes in the Heinkel design and the entire internal fuel load for the thirsty turbojet engine was to be stored across both of the wings. However, the wings were not armored which unduly would have exposed them to enemy fire even of the slightest degree.
After being subject to severe criticism, the project was cancelled by Heinkel at the end of February 1945 (Ref: 17, 22, 24).

Focke-Wulf Fighter Project II (MP-Models)

TYPE: Fighter, interceptor


POWER PLANT: One Junkers Jumo 004B turbojet engine, rated at 950 kp thrust

PERFORMANCE: 541 mph at 13,130 ft

COMMENT: The earliest known Focke-Wulf attempt at a single-turbojet fighter, shown in a drawing dated November 1942, the Focke-Wulf Fw 190TL, had involved simply bolting a very basic in-house designed turbojet Fw T.1 to the front of an operational Fw 190.
On January 1943, company aerodynamicist J. C. Rotta offered a report entitled “Fundamentals For The Design of a Turbojet Fighter” which looked at how a large turbojet fighter ought to be, what sort of shape and layout would be best, what turbojet engines could be fitted and how, what the advantages and disadvantages of piston engines and turbojet engines were and what aerodynamic issues were.
To illustrate his points, Rotta came up with a trio of remarkably foresighted designs:

Fighter with turbojet engine BMW 003, P 3302 Design 1,
Fighter with turbojet engine BMW 003, P 3302 Design2, and
Fighter with turbojet engine Junkers Jumo 004.

Each of the three designs had its turbojet engine mounted on its back, just as the Heinkel He 162 would be configured 20 months later. The first and third designs also had forward-swept wings and backward-swept V-tails. The second BMW powered P 3302 design had unswept wings and an unswept V-tail.
However, Focke-Wulf’s design team seem to have completely ignored Rotta’s ideas when they actually started work on a series of single-seat, single-engine turbojet fighters. A report from August 1944 charts the team’s progress through seven different designs.
The first of these, dated March, 1943, was a tail-sitter based on a Fw 190 but with the cockpit relocated to the nose in place of the familiar BMW 801 piston engine, with the turbojet positioned directly below. But with this arrangement no satisfactory rolling properties were to be expected and there was also the risk of burning the airfield surface.
The second design from June, 1943, seems th have been more highly regarded and had its own separate “Baubeschreibung” (Construction description) number, the closest thing Focke-Wulf had to a “P” designation.
The wing was mounted mid-fuselage and had a slight sweep on the leading edge and straight trailing edges, the tailplane was similar to the Fw 190. The design had a tricycle undercarriage and a Junkers Jumo 004B turbojet engine was positioned more centrally under the fuselage. The cockpit was heavily protected by armor of varying thicknesses. Armament was to be two MK 108 (70 rounds each) or MK 103 30mm cannon in the fuselage nose and two MG 151/20 20mm cannon (175 rounds each) in the wing roots.
The main advantage of positioning the turbojet engine under the fuselage was to facilitate maintenance, but there were several bigger disadvantages to this design, such as the nose wheel blocking the intake on take-off and landing, objects being sucked into the air intake since it was so close to the ground. and the damage or destruction of the turbojet engine in case of a belly landing.
Finally, this design was rejected.
As far as the other five different designs are concerned.  Two oft them were basis for the later Focke-Wulf twin-boom Fighter Projekt VIII „Flitzer“ („Streaker“) and  swept-wing, high-mounted tailplane featured Focke-Wulf  interceptor Ta 183 „Huckebein“ (Ref: 17, Uhr, D. and D. Sharp: „Luftwaffe:Secret Projects Profile“, Mortons Media Group Ltd., Horncastle, U.K., 2018).

Dornier Do 335A-6 (Dragon Models)

TYPE: Two-seat all weather and night interceptor

ACCOMMODATION: Pilot and radar operator

POWER PLANT: Two Daimler-Benz DB 603A-2, rated at 1,726 hp each

PERFORMANCE: 400 mph at 17,400 ft

COMMENT: The Dornier Do 335 “Pfeil” (“Arrow”) was a WW II heavy fighter built by the Dornier Company. The Do 335s performance was much better than other twin-engine designs due to its unique push-pull configuration and the lower aerodynamic drag of the in-line alignment of the two engines. It was Germany’s Luftwaffe fastest piston-engine aircraft of World War II. The Luftwaffe was desperate to get the design into operational use, but delays in engine deliveries meant that only a handful were delivered before the war ended.
In early 1944 the Do 335 was scheduled to begin mass construction, with the initial order of 120 preproduction aircraft to be manufactured by DWF (Dornier-Werke Friedrichshafen) to be completed no later than March 1946. This number included a number of bombers, destroyers (heavy fighters), and several yet to be developed variants. At the same time, DWM (Dornier-Werke München) was scheduled to build over 2000 Do 335s in various models, due for delivery in March 1946 as well.
While the Dornier Do 335A-0 assembly line at Oberpfaffenhofen was struggling to overcome delays in deliveries of power plants, airscrews, radio equipment and sub-contracted components and assemblies, a number of “Versuchs” (Test) machines for other “Pfeil” subtypes joined the test programme, these including the first two seat models, the Do 335A-6 bad-weather and night interceptor and the Do 335A-12 trainer..
The Dornier Do 335 V10 was the first prototype for the Do 335A-6 radar-equipped two set all weather and night interceptor in which a second cockpit for the radar operator was inserted aft and above the normal cockpit. In order to provide space for the additional cockpit the fuel tankage was drastically revised, the weapon bay being deleted and its space utilized for fuel, fuselage tankage being increased substantially. Cannon armament remained unchanged, but a FuG 101a radio altimeter was
introduced together with FuG 217J-2 “Neptun” intercept radar with wing-mounted antennae. Exhaust flame damping tubes for the fore and aft engines added their measure of drag to that provides by the second cockpit and the radar antennae, and normal loaded weight increased by app. 500 kg. Performance accordingly fell by 10 per cent, but whereas the Do 335 V10 had Daimler-Benz DB 603A-2 engines, the production Do 335 A-6 was intended to have DB 603E engines with provision for methanol-water injection (MW 50) for power boosting below the rated altitude of power plants. Provision was to be made in the wings for two MW 50 tanks, power being boosted to 2,400 hp at sea level per engine.
Production of the Dornier Do 335A-6 night and all-weather fighter had been transferred to the Heinkel factory at Vienna, but despite high priority allocated to the program, circumstances prevented the necessary jigs and tools being assembled (Ref: 7, 12).

Heinkel He 280 V6 (Huma Models)

TYPE: Fighter aircraft


POWER PLANT: Two Junkers Jumo 004B-1 turbojet engines, rated at 900 kp thrust each

PERFORMANCE: 508 mph at 19,685 ft

COMMENT: The Heinkel He 280 was the first turbojet-powered fighter aircraft in the world. It was inspired by Ernst Heinkel‘s’s emphasis on research into high-speed flight and built on the company’s experience with the Heinkel He 178 turbojet prototype. A combination of technical and political factors led to it being passed over in favor of the Messerschmitt Me 262 „Schwalbe“ (Swallow). Only nine were built and none reached operational status
The Heinkel company began the He 280 project on its own initiative after the Heinkel He 178 had been met with indifference from the Reichsluftfahrtministerium (RLM, Reich Aviation Ministry).
Work on the project began under the Heinkel designation „Projekt 1065“ in late 1939 but in March, 1940, after receiving official support the designation Heinkel He 280 was applied. The design had a typical Heinkel fighter fuselage, elliptical wings and a dihedralled tailplane with twin fins and rudders. Power was provided by two Heinkel HeS 8 centrifugal turbojet engines and had a tricycle undercarriage landing gear with very little ground clearance. This arrangement was considered too frail for the grass or dirt airfields of the era; however, the tricycle layout eventually gained acceptance. The He 280 was equipped with a compressed-air powered ejection seat, the first aircraft to carry one and the first aircraft to successfully employ one in an emergency.
The first prototype was completed in the summer of 1940, but the Heinkel HeS 8 intended to power it was running into difficulties. On September 1940, while work on the engine continued, the first prototype started glide tests with ballasted pods hung in place of its engines. It was another six months before the second prototype flew under its own power, on March 1941. The aircraft was then demonstrated to Ernst Udet, head of RLM’s development wing, on April, 1941, but like its predecessor, it apparently failed to make an impression. One benefit of the He 280 which did impress the political leadership was the fact that the jet engines could burn kerosene, which requires much less expense and refining than the high-octane fuel used by piston-engine aircraft. However, government funding was lacking at the critical stage of initial development.
Over the next year, progress was slow due to the ongoing engine problems. A second engine design, the Heinkel HeS30 was also undergoing development, both as an interesting engine in its own right, as well as a potential replacement for the HeS 8. In the meantime, alternative powerplants were considered, including the Argus As 014 pulsejet that powered the Fieseler Fi 103 V-1 Flying bomb. It was proposed that up to eight be used.
Engine problems continued to plague the project. In 1942, the RLM had ordered Heinkel to abandon the HeS 8 and HeS 30 to focus all development on a follow-on engine, the Heinkel/Hirth HeS 011, a more advanced and problematic design. But because the HeS 011 was not expected for some time, Heinkel selected the rival BMW 003. However, this engine also had problems and delays. The second He 280 prototype was re-engined with Junkers Jumo 004  The Jumo 004 engines were much larger and heavier than the HeS 8 that the plane had been designed for, and while it flew well enough on its first powered flights from March 1943, it was clear that this engine was unsuitable. The aircraft was slower and generally less efficient than the Messerschmitt Me 262.
Meanwhile, the He 280 V4 and V5 had been completed, the latter with Heinkel-Hirth 001 turbojets and the former with BMW 003A-0 turbojets. The He 280 V5 was considered by Heinkel tob e representative of he proposed He 280A-1 production standart. Ist claimed peformance include a maimum speed of 509 mph at 19,685 ft at normal loaded weight. The Heinkel He 280 V6 was completed with Junkers Jumo 004 engines and full armament from the onset. Amarment consisted of three 20 mm MG 151 cannon in the fuselage nose and one 500 kg or two 250 kg bombs. The He 280 V6 was tested at Rechlin, and in early 1943, Heinkel tendered a proposal to the Technische Amt for the He 280B-1 fighter bomber with two Junkers Jumo 004 engines and an estimated maximum speed of 547 mph.
By this time, flight testing of the Messerschmitt Me 262 V4 suggested that the Messerschmitt fighter would have a performance advantage over the Heinkel He 280 when fitted with similar power plants, and particularly in so fas as range was concerned, this being a serious defect in the Heinkel fighter’s performance. Thus, on March 1943 the Technische Amt instructed Heinkel to abandon all further development of the He 280 as a fighter, permission being given to complete only the nine prototypes which were allocated to various test programmes (Ref.: 7, 24).

Messerschmitt Me 609 (Huma-Models)

TYPE: Fighter, Fighter bomber


POWER PLANT: Two Daimler-Benz DB 603 liquid-cooled engines, rated at 1,726 hp each

PERFORMANCE: 472 mph (estimated)

COMMENT: The Messerschmitt Me 609 was a short-lived WW II German project which joined two fuselages of the Messerschmitt Me 309 fighter prototype together to form a heavy fighter.
The project was initiated in response to a 1941 RLM (Reich Air Ministry) requirement for a new “Zerstörer” (destroyer, or heavy fighter) to replace the Messerschmitt Bf 110 in a minimum time and with a minimum of new parts The new design would use components from existing aircraft, thus not disrupting existing production. After the cancellation of the Messerschmitt Me 309 project in 1943, work was continued using it as a basis for other designs. One of these reworked designs was for the Me 509; another was for the 609, which was basically two Me 309 fuselages joined with a new center wing section. Messerschmitt was also working on and had completed a twin-fuselage Bf 109, known as the Me109Z, but the prototype was destroyed before flight testing.
Two Me 309 fuselages were to be joined with a constant chord center wing section, into which two inboard landing gears retracted. The outboard landing gears were resigned, two nose wheels retracted to the rear and rotating 90 degrees to lie flat beneath the engines. This resulted in an unusual four-wheel arrangement.  Power was to be supplied by two Daimler Benz 603 or 605 12 cylinder inverted V liquid -cooled engines. The pilot sat in a cockpit located in the port fuselage, with the starboard cockpit canopy being faired over.
Two versions were envisioned: a heavy fighter (“Zerstörer”) and a high-speed bomber (“Schnellbomber”, fast bomber). In the fighter version, two MK 108 30 mm cannon and two MK 103 30mm cannon were projected as the armament, with a provision for two additional MK 108 30mm cannon mounted beneath the center wing section or under the outer wing sections. In addition, either one SC 500 or two SC 250 bombs could be carried, also beneath the center wing section. The fast bomber version would have reduced armament, with only two MK 108 30mm cannon were to be installed. Extra fuel (1500 kg) could be carried in the faired over starboard cockpit, and the bomb load was to consist of two SC 1000 bombs which were carried beneath each fuselage.
Finally, a two seater night fighter variant was envisioned with FuG 220 “Lichtenstein SN-2” antennas mounted at the outer wings. The pilot sat in the port and the radar operator in the starboard fuselage.
Even though it was calculated that many components of the Me 309 could be used (fuselage, engines, equipment, 80% of the wings), by the time this design began to jell, the Messerschmitt Me 262 turbojet fighter was proving to be the plane of the future, and could take over all roles for which the Me 609 was designed. Thus, the Me 609 project was no longer pursued after 1944 (Ref.: 24).

Braunschweig LF 1 ‘Zaunkönig’ (“Wren”) with Panzerfaust 100 (Bazooka), (Luedemann Models)

TYPE: Short Take-Off and Landing aircraft


POWER PLANT: One Zündapp Z9-092 air-cooled, rated at 50 hp


COMMENT: The Braunschweig LF-1 “Zaunkönig”, (“Wren”, LF = Langsames Flugzeug, Slow aircraft), is a Short Take-Off and Landing single-seat light aircraft designed in 1939 by Hermann Winter  and some of his students from the Technische Universität Braunschweig (Technical University of Brunswick), Lower Saxony, Germany, as a fool-proof trainer for novice student pilots to experience solo flight. H. Winter was a former chief engineer at the Bulgarian company DAR (Drzhavnata Aeroplanna Rabotilnitsa, where he created a line of aircraft and gliders for the Bulgarian Army.
The LF-1 is a parasol wing monoplane with a high set tail-plane, powered by a Zündapp Z 9-092 engine delivering 50 hp, able to operate from a 330 ft airstrip. The two-piece wings are set at 16° dihedral and are supported by a pair of V-cabane struts and V-struts either side from approximately half-span to the lower center fuselage. Full span leading edge slats extend automatically and full span trailing edge flaps / drooping ailerons can be extended manually by the pilot. The fixed tailwheel undercarriage attaches to the fuselage with long struts and oleo pneumatic shock absorbers.
It was a proof-of-concept design for a ‘fool-proof’ trainer intended for novice pilots with only one hour of ground instruction, the hour being reduced to five-minutes for those who had already flown gliders, and was intended to be impossible to either stall or spin.
The first prototype, the LF-1 V1, was built in 1940 and made its maiden flight, piloted by Winter himself, in December 1940. Test flights stopped in November 1942 after part of the wing ruptured causing the aircraft to crash. In 1943 a second prototype, the V2, was built, receiving the civil registration D-YBAR.
In early 1945 the aircraft was tested for military applications and was once even armed with a Panzerfaust 100 recoilless anti-tank weapon (Bazooka).
At the end of WW II the LF-1 was taken to the Royal Aircraft Establishment (RAE) at Farnborough for slow flying tests; given the British serial VX190, where amongst others, it was flown by Eric “Winkle” Brown CO Aero Flight, the aircraft also being soloed by the then-head of the RAE Aerodynamics Section, Handel Davies, after half an hour of ground instruction, and whose only previous piloting experience was as a pupil in a dual-control Miles Magister.
Encouraged by the positive British reviews Hermann Winter decided to build three more LF-1 aircraft. The construction started in 1954 and it was the first new aircraft in Germany after the war to receive a certificate by the Luftfahrt-Bundesamt (LBA) in Braunschweig (Ref.: 24).

Heinkel He 162S (A+V Models, Resin)

TYPE: Trainer glider for Heinkel He 162 turbojet aircraft

ACCOMMODATION: Crew of two, Pilot and student


PERFORMANCE: No data available

COMMENT: The Heinkel He 162 „Volksjäger“ (“People’s Fighter”), the name of a project of the „Jägernotprogramm“ (Emergency Fighter Program) design competition, was a German single-engine, jet-powered fighter aircraft fielded by the Luftwaffe in WW II. It was designed and built quickly and made primarily of wood as metals were in very short supply and prioritised for other aircraft. „Volksjäger“ was the RLM’s (Reich Air Ministry’s) official name for the government design program competition won by the He 162 design. Other names given to the plane include „Salamander“, which was the codename of its construction program, and „Spatz“ (“Sparrow”), which was the name given to the plane by Heinkel.
The „Volksjäger“ needed to be easy to fly. Some suggested even glider or student pilots should be able to fly the jet effectively in combat, and indeed had the Heinkel He 162 gone into full production, that is precisely what would have happened. After the war, Ernst Heinkel would say, “[The] unrealistic notion that this plane should be a ‘people’s fighter,’ in which the „Hitler Jugend“ (Hitler Youth), after a short training regimen with clipped-wing two-seater gliders like the DFS „Stummel Habicht“, could fly for the defense of Germany, displayed the unbalanced fanaticism of those days.”
The clipped-wingspan DFS „Habicht“ (Goshawk) models had varying wingspans of both 8 m or 6 m, and were used to prepare more experienced Luftwaffe pilots for the dangerous Messerschmitt Me 163B „Komet“ rocket fighter – the same sort of training approach would also be used for the „Hitler Youth“ aviators chosen to fly the jet-powered „Volksjäger“ design competition’s winning airframe design.
Besides the „Stummelhabicht“ a standard-fuselage length, unarmed BMW 003E-powered two-seat version (with the rear pilot’s seat planned to have a ventral access hatch to access the cockpit) and an unpowered two-seat glider version, designated the Heinkel He 162S („S“ for Schulen, Training establishment), were developed for training purposes. Only a small number were built, and even fewer delivered to the sole He 162 „Hitler Youth“ training unit to be activated in March 1945 at an airbase at Sagan (now Poland). The unit was in the process of formation when the war ended, and did not begin any training; it is doubtful that more than one or two He 162S gliders ever took to the air (Ref.: 24).
