The Bell UH-1 family of helicopters has been built in greater numbers since the end of World War II than any other military aircraft and has been flown by more national air forces than any other type. Based on the XH-40 prototype, which was built by Bell in response to the US Army's need for utility and casualty evacuation helicopters. The first production helicopter, the HU-1A, a designation it received later, entered service in the late 1950s. In 1961, Bell refined the design and created the Model 205 helicopter, using a longer fuselage and a more powerful engine.
As a result, the UH-1D/H helicopters became the most popular among the military - they remained in production until 1986. Only 2,008 modification D helicopters were delivered to the US Army. The basis of airmobile units in the Vietnam War - the Iroquois helicopter - was also armed with various machine guns during the war, both stationary in hanging containers and manually controlled uncontrolled, and was also used in role of a helicopter artillery battery.
Further modifications included helicopters equipped with two naval engines, anti-submarine radar for sea search, and a very enlarged helicopter to transport 17 soldiers - the original UH-1A could only accommodate six. Still in widespread use today, the Bell UH-1 helicopter, in its many variants, will undoubtedly play an important role in the military well into the 21st century. A large number of Iroquois helicopters released from military service were sold to private customers, mainly in the USA, where they perform a wide variety of work.
The equipment that is primarily associated with the Vietnam War is the American Bell UH-1 Iroquois helicopter. At one time, helicopters performed very well in Korea. This forced the American command to pay special attention to them.

In the early 50s, a competition was held to create a light multi-purpose helicopter with the ability to install machine guns and missile weapons. In 1955, the Bell Helicopter Company project was recognized as the best option.
The first prototype (Model 204) was powered by a Lycoming T53 turboshaft engine. The first flight of the prototype took place on October 20, 1956 in Fort Worth (Texas). The military version was designated the HU-1 Iroquois (later UH-1). UH-1A helicopters with the Lycoming T53-L-1A engine (770 hp) went into serial production.

The Bell UH-1 Iroquois is a classic single-rotor helicopter with a two-bladed main rotor and a two-bladed tail rotor. The fuselage structure is semi-monocoque, consisting of a two-seat pilot's cabin, a cargo compartment and a tail boom. The functions of the landing device are performed by steel skis. The power plant is located in the upper part of the fuselage and consists of one or two engines, depending on the modification of the helicopter. The fuel system consists of two tanks (625 l), which are located behind the cockpit. The helicopter can carry machine guns and missiles.
Over time, new modifications of this machine appeared. In 1961, UH-1Bs began to enter the army, equipped with the T53-L-5 engine (960 hp). In 1963, the US Marine Corps received UH-1E helicopters, which were equipped with more modern radio equipment. In 1965, a new modification of the vehicle appeared, the UH-1C, which featured an improved rotor design. The UH-1D featured a new fuselage design that made it possible to increase the volume of the cargo compartment. Since 1965, attempts have been made to install two engines on the UH-1. The result was a modification of the UH-1N with two Pratt&Whitney PT6T-3 engines (total power 1800 hp). The Iroquois is one of the most produced helicopters in the history of American aviation, with more than 8,000 units built. The car was exported and produced under license abroad.

The range of applications of this helicopter is very wide; it was actively used in army and civil aviation in different countries. It appeared in many military conflicts as an airborne assault and fire support helicopter.

Radio-controlled helicopters – there are many models, but there is only one choice!
A radio controlled helicopter is the dream of many! He can fly, hover in the air, and surprise everyone around with aerobatics! Choosing the right model is not difficult - you just need to decide on the size, number of channels and screw pattern.
1. Large, medium, small?
The size of the toy is determined by where it is used. Small helicopters less than 25 cm in size are intended for home use, medium ones (up to 40 cm) are for large rooms and windless weather, large helicopters (more than 40 cm) are only for the street.
2. 3 or 4 channel?
The degree of ease of helicopter control depends on the number of channels. 3-channel ones are simpler, even a child can handle them. For adults and those who are already familiar with radio-controlled equipment, more maneuverable 4-channel helicopters are recommended. There are also 6-channel radio-controlled helicopter models, but this option is for the pros.
3. Classic or coaxial screw design?
A coaxial design consists of two screws placed one above the other. This scheme is ideal for children and beginners. It guarantees easy control and stable flight, but is vulnerable to strong gusts of wind.
Models with a classic design are the opposite – they are not afraid of the wind. They are equipped with one very fast propeller, providing higher speed and maneuverability, but at the same time requiring experience in operating such equipment.
As you can see, choosing a radio-controlled helicopter is easy! In practice, it looks like this: the easiest model to control will be a small 3-channel coaxial helicopter, and the most difficult will be a large one, with four channels and a classic propeller design.
Plastic rotorcraft will decorate your office or room if you put in a little effort and set aside a couple of evenings. A prefabricated model of a helicopter will look perfect if it is not installed on a stand, but hung on a special system from the ceiling. A helicopter is like a butterfly, much more beautiful in flight than on the ground.
What types of helicopters are there?
For most people, their ideas about helicopters begin and end with the MI 8 model. Yes, this is the most popular brand of helicopter in the world. The more advanced MI 24 and MI 26 received their development from him.
But how many people know that the largest and most heavy-duty helicopter in the world was designed and created in the Soviet Union?
This record holder is MI 10. The records he set have been standing for half a century, and an objective look at helicopter manufacturing allows us to assume with great confidence that this achievement will not be surpassed very soon.
For such giants, a scale of 1/144 is used. Most of the other models are produced in the popular 1/35 scale.
Finishing
The assembled model, regardless of the material, must be coated with paint and pasted over with decals. Only in this form will a prefabricated copy of the helicopter serve as an embodiment of the power of domestic science and technology.
It is best to hang the finished product on special fittings from the ceiling. After all, a helicopter is designed to fly, and it doesn’t matter what size it is.
