Product Introduction
产品背景
Background
Unimog is an abbreviated name, which stands for "Universal-Motor-Gerät" in German, meaning "universal motorized
device." In the late stages of World War II, influenced by the Morgenthau Plan, Germany was required to divest its
military industry. German engineers, with nothing to do in the military sector, turned their focus to designing agricultural
machinery. Albert Friedrich, former head of aircraft engine design at Daimler-Benz, was one of those engineers. His
idea began with a simple sketch, resulting in a machine with full-time four-wheel drive, equipped with differential locks,
portal axles, and the ability to power external devices.
The new vehicle not only achieved great success in agriculture but also gained favor from the public sector. Customers
requested standardized power take-off interfaces for the Unimog to enable the installation of a wider variety of tools. In
the autumn of 1950, Daimler-Benz took over the entire Unimog project, and production was relocated to the original
load-carrying vehicle factory in Gaggenau. In 1953, the Mercedes-Benz three-pointed star emblem replaced the early
Unimog's bull head logo and has been used ever since. The Unimog 421 series was manufactured between 1966 and
1989 and was widely used in agriculture, forestry, firefighting, and other sectors.
Unimog是一个缩写名称，全称为"Universal-Motor-Gerät"，意思是"万能机动工具"。二战后期的德国阴云密布，受摩根索计划（
Morgenthau Plan）影响，德国必须剥离军工产业，德国工程师们无事可做只能转而设计农用机具。戴姆勒-奔驰公司飞机发动机设计部
门前负责人阿尔伯特·弗里德里希(Albert Friedrich)就是其中之一，他的想法从一张草图开始，全时四轮驱动，配备差速锁，门式桥，前后
桥都可输出动力来驱动外接设备的机器由此诞生。
新车不仅在农业方面大获成功，还受到公共部门的青睐，客户要求乌尼莫克配备标准化的取力器接口，以便安装更多种类的工具。
1950年秋天，戴姆勒-奔驰接手整个乌尼莫克项目，生产迁至位于加格瑙的原载重车工厂。1953年奔驰三叉星徽取代了早期乌尼莫克的牛
头标应用至今。乌尼莫克421系列制造于1966-1989年间,广泛地应用于农业、林业、消防等单位。
产品介绍
About Model
Authorized by Daimler-Benz AG, this 1/24 scale remote-controlled simulation model of the Unimog421, introduced by
FMS, maintains a consistently high level of visual simulation. This model is designed for typical special transport
scenarios and can handle transportation tasks in complex road conditions. It features a highly restored grille, widened
rear-view mirrors and snorkel, and two orange warning lights on the roof. Through the windows, you can see the
exquisite dashboard and cabin interior. The engine hood can be opened, providing convenience for battery replace-
ment, and it also serves as a storage space for the electronic board of the remote control system. In addition, the rear
cargo compartment and the three-side wall panels are made of wood. We have carved intricate patterns on the model
car to simulate the texture of real wood.
Unimog adopts the FCX24 series high-performance crawler chassis (with added realistic parts like fuel tank, accumu-
lator on). The car frame is made of high-strength nylon. Compared to the trapezoidal beam spliced by metal side
beams and plastic trusses, the overall weight is lighter and the strength is higher. The mid-mounted power assembly
has a low center of gravity and integrates the 2-speed transmission, transfer case and 130 motor. The power is
transmitted to the front and rear axles through the universal joint drive shaft. The axles are equipped with wheel side
reducers, commonly known as "portal axle", which can increase the ground clearance of the differential tooth pack and
improve passability.
The crawlers are generally equipped with front and rear straight axles to simulate the locked state of the real car
differential to improve off-road passing ability. The FCX24 is equipped with a straight axle by default, but the planetary
gear differential can also be replaced with high-viscosity silicone oil to simulate the driving effect of an LSD limited-slip
differential. After installing the differential, the ultimate climbing ability will be reduced, but a smaller turning radius and
a more stable high-speed driving quality can be obtained. Simply put, the straight axle is suitable for extreme climbing,
and the limited-slip differential is suitable for high-speed off-road. The choice is yours.
