The war situation was deteriorating day by day. Enemy heavy bombers invaded and arrived at the heart of the country without any problem. In order to bring about a miracle to the German Army which was about to be defeated, they had to work out a way to effectively attack the enemy's strategic sites. Under the circumstances, the Luftwaffe requested a "twin-engine high-speed bomber capable to reach the enemy lines where we don't own air superiority". What was the answer from the Dornier Company which had gotten a patent for tandem-mounted engines? The answer was an aircraft which was transformed from a bomber to a multi-role heavy fighter in the development stage. On the robust fuselage the DB 603 A were installed back and forth, making it a high-speed fighter with a phenomenal thrust power, the main girder of the box structure supporting the tough main wings is another particularity of this Luftwaffe double-engine aircraft. Everything is reproduced with this SWS kit.
▋DB 603 A
DB 603 liquid-cooled inverted V-type 12 cylinder engine made by Daimler-Benz . Its design was based on DB601 engine which adopted many advanced and complicated systems such as direct injection pump, variable speed supercharger, and many roller bearings. Even though these systems make it difficult to manufacture the aircraft, the company overcame it with high technology and maintained its superiority over the other aircrafts. The engine's displacement was 44,510cc, take-off power output was 1,750hp／2,450rpm. These engines, installed back and forth in a "push-pull" layout, were the source of the plane's capacity to reach the enemy lines without air command.

The plane had two VDM propellers—one mounted in front and one at the back. The shapes and diameters of these two propellers are different, so we made more elaborately research on them than usual. The front propeller is a tractor propeller with a diameter of 3.5m. The trailing edge has a flat surface like being cut off. The rear propeller is a pusher propeller with a diameter of 3.3m, and it is directly connected to the engines with an extending shaft. The extending shaft separates in two parts in its middle, the coupling part becoming the gear coupling type, which allows flexibility even if the center axis slips off to some extent due to the torsion of the fuselage. One thinks that by adopting this device, the Luftwaffe wanted to prevent resonance and damage to the aircraft. By the way, in the aircraft manual, the word "luftschraube" (literally "air screw") is used to describe the propellers.
