“Ja-3” – the USSR truck

In the autumn of 1924, the factory's group of designers, led by V. Danilov, began designing a truck with a lifting capacity of three tons. Their colleagues from the Moscow plant AMO helped. As early as 1923 the modernization of the 3-ton "White" truck was carried out in this factory under the leadership of the chief designer Cipulin. The main change was replacing the chain drive to the rear axle with a cardan. Later all documentation was transferred to Yaroslavl. The car was planned to be released for the May 1st 1925 holiday, but due to delays in the supply of the complete parts, the deadline was moved to another important date in Soviet life. The first two trucks were completed in Yaroslavl on the eve of November 7 and immediately went to tests. One car had to overcome the trace Yaroslavl - Rostov - Yaroslavl, the length of which is 133 km, the other was tested in Moscow Autotrest and NAMI. After the tests Ja-3 (Russian: Я-3) - "Yaroslavl 3 tons" - was accepted into serial production. The car turned out to be slow due to the used AMO engine, but very expensive. The frame of the machine was made of a rolled profile, equipped with an engine from "AMO F-15" and acetylene lights. Unnecessary luxury is used in the decoration of the machine - the cabin is made of oak, the seats are covered with natural leather, the carriage is varnished. Pine and dermatan were used in later models. A total of 160 Ja-3 units and several dozen chassis for buses and fire trucks were produced in 1925-1927.

A moderately complex, well-detailed, well-designed model for a modeler of any experience. Fully detailed cabin interior, engine compartment, chassis, cargo platform. Working under the supervision of a more experienced colleague, this model can be assembled by an advanced beginner and a modeler with little experience, but they should build a model without the cabin interior, engine compartment detailing, with opaque windows and a simplified chassis.
