Features:
The Stirling Engine Principle was invented in 1816 by a pastor Robert Stirling in London, so it was named Stirling engine. The Stirling engine is a unique heat engine because their theoretical efficiency is almost equal to the theoretical maximum efficiency, called the Carnot cycle efficiency. The Stirling engine is powered by the expansion of the gas and the contraction of the cold. This is an external combustion engine in which the fuel is continuously burned, the expanded air (helium ) acts as a medium to move the piston, and the expanded gas is cooled in the cold chamber, and such a cyclic process is repeatedly performed. Only a small alcohol lamp is needed to make it fly fast and powerful.

MinimumRC A6M2 Zero Backyard Fighter Series 240mm Wingspan Warbird RC Airplane KIT+Motor/PNP

To Buy It Click Here

The Mitsubish.i A6M "Zero" is a long-range fighter aircraft manufactured by Mitsubish.i Aircraft Company, a part of Mitsubish.i Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945. The A6M was designated as the Mitsubish.i Navy Type 0 carrier fighter , or the Mitsubish.i A6M Rei-sen. The A6M was usually referred to by its pilots as the "Reisen" (zero fighter), "0" being the last digit of the imperial year 2600 (1940) when it entered service with the Imperial Navy. The official Allied reporting name was "Zeke", although the use of the name "Zero" was later adopted by the Allies as well.

 

The Zero was considered the most capable carrier-based fighter in the world when it was introduced early in World War II, combining excellent maneuverability and very long range. The Imperial Japanese Navy Air Service (IJNAS) also frequently used it as a land-based fighter.

 

In early combat operations, the Zero gained a legendary reputation as a dogfighter, achieving an outstanding kill ratio of 12 to 1,but by mid-1942 a combination of new tactics and the introduction of better equipment enabled Allied pilots to engage the Zero on generally equal terms.By 1943, the Zero became less effective against newer Allied fighters because of inherent design weaknesses and the failure to develop more powerful aircraft engines. The Allied fighters gained greater firepower, and speed, and approached the Zero's maneuverability, and the Mitsubish.i A6M was outdated by 1944. However, the Zero continued to serve in a front line role until the end of the war because design delays, and production difficulties, hampered the introduction of newer Japanese aircraft. The Zero was also adapted for use in kamikaze operations during the final year of the war.Japan produced more Zeros than any other model of combat aircraft during the course of the war.
