Man muss zweimal hingucken, um die Veränderungen zu erkennen, die aber umfangreicher waren als man meint. Hintergrund für dieses Whif war, dass in Deutschland mit dem Aufkommen der ersten Strahltriebwerke u.a. überlegt wurde, herkömmliche Typen mit diesen als "Boostern" auszustatten. Auch die Entwicklung von Turboprop-Triebwerken und darauf basierender Flugzeuge war ebenfalls im Gange.
Was also, wenn ein geeignetes Triebwerk zur Verfügung gestanden hätte, um einem bewährten Flugzeugtyp neues Leben einzuhauchen? Ein mögliches Ergebnis ist diese (gänzlich fiktive) Me 510.

Basis ist der einfache Me 410-Bausatz von Matchbox in 1:72, von dem aber nur der Rumpf (und das irre dicke Glasteil...) übrig blieb. Kern des Umbaus sind implantierte Tragflächen einer Il-28 in 1:100 vom Tamiya - aber umgedreht, und mit verschlossenen Fahrwerkschächten, sowie ergänzten Propellern. Die schmalen Tragflächen an den Rumpf zu bekommen war ziemliche Arbeit, ist aber ganz gut gelungen.
Auch das komplette Leitwerk ist neu. Es sollte in den Umrissen zu den neuen, eckigen Tragflächen passen, und so sind die Höhenruder Tragflächenspitzen von einer Me 262, das Seitenruder eine gekappte Tragfläche eine Grumman Panther.
Das Fahrwerk ist OOB, erhielt aber neu geschnittene Schächte. Die Kanone vorne ist auch authentisch, erhielt aber eine neue Mündungsbremse und stellt ein späteres Modell (die BK 214B, s.u.) dar.
Die Propeller stammen von je einer Mustang, die Spinner sind gescratcht, wie auch das Cockpit-Innenleben mit Seitenkonsolen und neuen Sitzen. Nix Authentisches (wie auch?), aber was fürs Auge

Der Anstrich lehnt sich in Markierungen und Farben an reale Vorbilder an, ist aber letztlich ebenfalls fiktiv. Aber
so könnte so was ausgehen haben...

Und noch die Story dazu...The Messerschmitt Me 510 was a further development of the Me 410 Hornisse ("Hornet"), a German heavy fighter and Schnellbomber used by the Luftwaffe during World War II. The 410 itself had a troubled start, because it essentially had only been a straightforward modification of the Me 210, which had suffered from serious stability flaws and had a bad reputation among its crews.
The 410 handled better but did not show much improvement in performance, though. Me 410 deliveries began in January 1943, two years later than the original plan had called for, and continued until September 1944, by which point a total of 1.160 of all versions had been produced by Messerschmitt Augsburg and Dornier München. When it arrived, it was liked by its crews, even though its performance was not enough to protect it from the swarms of high performance allied fighters they faced.

Still not giving up on the original construction (and with the jigs and tools still available), Messerschmitt started in early 1944 with research into further means of improving the Me 410's performance. One direction was the addition of one or two jets under the fuselage as boosters for combat situations.
Another design path, which eventually led to the Me 510, was the development of turboprop and compound engines as propulsion options, which were based on the respective pure jet engines but offered much better performance and fuel economy than the pure jets. It would also be the more efficient solution compared to added turbojets for pure piston planes, since no dead weight had to be carried, and the overall system was less complex than a mixed powerplant system.

This turboprop concept, as best compromise between performance and short-term readiness for service, was chosen and the modified aircraft, called Messerschmitt Me 510, came to be. The design target was to outperform the Me 410 with as little change to the overall construction as possible, so that old tooling could be used for new aircraft cells. Alternatively, old aircraft should potentially be converted to the improved standard.
Core of the new development was the compact HeS 021 turboprop, a PTL development of the HeS 011 jet engine which was also planned for Focke Wulfs FW P.0310226-127 fighter (a turboprop version of the light 'Flitzer' day fighter). This engine was theoretically to deliver up to 3.300hp (2.426 kw) shaft output, plus 1.100kg (2.424 lb) additional thrust, even though serial types would produce less power under the aspect of reliability.

In order to incorporate this engine into the modified Me 410 a new main wing with laminar profile and new engine nacelles had to be designed. The HeS 021sat in the front part of the engine nacelles above the wings, driving four-bladed propellers. The landing gear retracted into the nacelle's lower section, rotating 90°, much like the Me 410, with the exhaust running above the landing gear wells.
In order to improve directional stability further, the tail surfaces were slightly enlarged, receiving characteristic, square tips. The fuselage was more or less taken from the original Me 410, since it offered a very good field of view and appropriate aerodynamics. With this package, the idea of retrofitting former Me 410 cells was kept, even though later flight tests showed that some more detail modifications had to be made. Most of these concerned the internal structures, the most obvious external change was the nose section, where the original glazing had to be reinforced and finally replaced by solid material – an experience similar to the modification from Douglas’ piston-driven XB-42 to the faster, jet-driven XB-43 of the same era.

Maiden flight of the first prototype took place in Augsburg on 6th of May 1945, with little problems. As benchmark, the Me 410's maximum speed was 625 km/h (388 mph), a cruise speed of 579 km/h (360 mph) and a combat range of 2.300 km (1,400 mi) with up to 1.000 kg (2,204 lbs) of disposable stores carried in- and externally.
The overall flying characteristics of the Me 410 did not change much, but rate of climb and top speed were considerably improved. In level flight, the third prototype Me 510 V3 reached a top speed of 812 km/h (504 mph), and even the serial version with added armament and equipment easily reached 750 km/h (465 mph) top speed and a cruising speed with no external stores of 650 km/h (405 mph). At its time, the Me 510, which quickly received the rather inofficial nickname "Bremse" (Horsefly), was superior to its pure piston engine and turbojet rivals, even though it was clear that the turboprop was only a preliminary solution.

Due to its high speed and under the pressure of Allied bomber raids, the Me 510 was primarily used as a Zerstörer against daylight bombers. Many aircraft received additional weapons, both directly incorporated at the factory but also as field accessories. Popular modifications included two extra 30mm guns (MK 108 or 103) in the bomb bay, or provisions for guided and unguided air to air missiles. A camera equipment package (Rüstsatz 'U3') allowed the fast aircraft to be used for daylight reconnaissance.
Many equipment packages from the earlier Me 410 could be fitted, too, including the massive 50mm BK 5 auto cannon against allied bomber groups. Initially, this package (‘U4’ Rüstsatz) comprised the original autocannon which fired at 45 RPM, with 21 shells in a drum magazine.

This weapon soon was replaced by the even more effective MK 214 B gun of 55mm caliber (Rüstsatz 'U5'). The BK 214 B fired at 180 RPM and proved to be a highly effective weapon at long ranges, outside of the bombers’ defensive armament range. As a drawback the heavy system (the gun plus the ammunition belt with 96 shells weighed 1.124 kg/2.475 lb) filled the whole internal bomb bay and precluded heavy external stores. Therefore, the 13mm machine guns in the nose were frequently removed in order to save weight, sometimes the weapons in the side barbettes, too. But: a single hit with one of the 1.54kg (3.4 lb) shells was enough to bring down a four-engined bomber, so that the fast Me 510 with this weapon became a serious threat in the course of late 1946.Me 510 general characteristics:Crew: 2
