Quadrocopter are now among the most popular radio-controlled model airplanes. Originally still the remote-controlled helicopters assigned, they now have their own division as Multicopter caused. Multicopter stands for one flight model, which has more than two mounted in a plane down-facing rotors. In detail, this generic term also includes:
- Tricopter with three rotors
- Quadrocopter with four rotors
- Hexacopter with 6 rotors
- Octocopter with 8 rotors
Aircraft models with an even higher number of rotors are so far reserved for self-construction or future developments, which then complement this list accordingly.
Quadrocopter There are very different designs and price ranges, so beginners and professionals can find a suitable model in the market for themselves. While most Quadrocopter are designed for an outdoor flight, there are also smaller ones Indoor models, which can be flown outdoors only in calm weather.

What is a quadrocopter?
Similar to a helicopter needed Quadrocopter no wings to gain buoyancy through airflow. A flight is made possible by down-directed propellers, thereby also vertical take-off and vertical landing are possible. Compared to helicopters requires one Quadrocopter but hardly any mechanical components, for example adjustable rotor blades or swashplates. Also eliminates a tail rotor, which at a Helicopter is needed for balancing the torque transfer to the chassis. On Quadrocopter has opposite rotors to compensate for the torque. Flight, position and movements are only achieved by speed changes of the individual engines, which Quadrocopter especially for Beginners recommended although they have all the control features of a helicopter.
How does a remote-controlled quadrocopter work?
On a chassis are four booms on which the four electric motors are mounted with their rotors at the required distance from each other. Partially (depending on the model), a gear between motors and rotors may be interposed. Two pairs of rotors run in opposite directions, which compensates the torque and creates a relatively stable attitude. Flight movements can be achieved by changing the engine speeds. Some models use as in Helicopters gyrosto stabilize the independent attitude. at quadrocopters the flight weight is distributed to the four rotors. This can be compared to a helicopter smaller engines and rotors are used. This allows a robust constructionwhich reduces damage to the models in the event of a crash. Also allow Quadrocopter a high load capacity, so that they are often additionally equipped with cameras, for example. The manageable flight characteristics of the Quadrocopter has also made it interesting for purposes other than hobby model flying. They are used, for example, for surveillance and transport flights. In addition to the drive unit need Quadrocopter of course the usual components of remote-controlled models:
- Power supply (battery)
- receiver unit
- Radio remote control transmitter
- landing gear
- Speed governor
- GPS system
Before buying a quadrocopter, think about where you want to and want to let it fly. It is important to note the regulations for quadrocopters (drones).
The GPS system
By the Global Positioning System (GPS) one can Quadrocopter, for example the Revell Control RC GPS Quadcopter, perform additional functions. For example, it will stay in place when the joystick is released. In addition, the GPS can also be used to let a model advised from the transmission range return again. Some models allow automatic follow-up of the transmitter or preset navigation points. Telemetry data such as speed, altitude, position, state of charge of the power supply are often transmitted.
- with GPS system (Position Hold and Coming Home) and Follow Me function
- Full HD camera (1.080p) - Recording via micro SD-HC card to 64 GB (card not included) - Live image via remote control display
- Brushless motors and 2 speed levels with flip function
- 4 channel 2,4 GHz remote control system (switchable mode 1 / Mode 2)
- stable flight through 6 Axis gyro system, headless mode, height sensor - including LED lighting and replacement rotors
The radio remote control
The radio remote control meets primarily in one Quadrocopter the same requirements as with all remote-controlled models. With it all functions can be controlled by radio. There are different control channels available. Depending on the functionality of the model, 4 to 6 channels or more are needed. The frequency ranges of the radio remote controls are 27 MHz, 35 MHz (only approved for model aircraft) 40 MHz and 2,4 GHz. Especially the newer 2,4 GHz remote controls are characterized by high reliability. If the model is equipped with a camera that sends the images via radio in real time to a receiver, make sure that the radio signals of the transmitter and the camera do not interfere with each other. For example, there are wireless cameras that use the 5,8 GHz range for transmission. There are complete sets in which the radio camera with receiver is already included. Often they even have a small display in the radio remote control, or at least allow the connection of a display.
The receiver unit
Suitable for the transmitter, a receiver is required. It processes the received control signals and passes them on to the components, for example the speed controllers of the motors. The receiver must have the appropriate number of channels for each function and use it over the same frequency range and transmitter channel of the radio remote control. In older radio remote controls, a channel change is effected by changing plug-in quartz (transmitting and receiving quartz).
The speed controller
To regulate the speed of the electric motors speed controllers are required as with other electric models Quadrocopter according to the 4 engines four pieces. By operating the joystick on the remote control, the speed controller connected to the receiver then regulate the speed of the individual rotors or the associated electric motors. Also gyroscopes can be used to stabilize the speed controller Quadrocopter drive.
The electric motors
Because of the efficiency will be at quadrocopters frequently Brushless motors used. They achieve very high speeds and are relatively wear-resistant compared to brush motors. Internal combustion engines are generally only used by professional model manufacturers for larger models. Compared to electric motors, they are louder, generate exhaust gases and require a gasoline mixture that is flammable and toxic.
The required power for Quadrocopter deliver Accumulators (rechargeable battery), It refers to rechargeable energy storage, The big advantage is compared to batteries, they do not have to be renewed as soon as they are empty. Batteries are also preferably used in the radio remote controls to reduce costs there. However, a rechargeable battery and a charger is required, which is often already included in the sets.
Different types of quadrocopters
Depending on size, equipment and intended use, there are different types and models of the trade Quadrocopter to disposal. Choose the ideal model for yourself. We'll help you!
Quadrocopter (mini quadrocopter) for indoor use
Similar to the small one Mini helicopters there is also Mini Quadrocopter, They are particularly suitable for flight in spacious rooms, halls or even in the cold, even for outdoor use. They are very small and light. The low weight does not pose such a great challenge to the engines, which is why very small and energy-saving engines can be found. But they are very vulnerable to wind and can not be controlled anymore - or only very badly. Their low price and their easy handling make Mini Quadrocopter ideal for children, beginners or beginners. Due to its low weight, damage to the model and furnishings in the event of a fall is significantly lower. In terms of price, they are in the range between 20 and 70 Euro, such as the Archer Skytech M62 Mini Quadcopter.
- Compact and lightweight design. With LED lights it is possible to fly at night.
- The 6 Axis system allows the quad to be started by hand.
- Stable: 6-Axis Gyro Quad-Rotorcraft Flight, strong stability, easy to implement different flight movements Stronger Wind Resistance, easier to control.
- 2.4 technology adopted for anti-interference. Even multiple quadcopters can fly at the same time without interfering with each other.
- Rechargeable high-performance battery, you can enjoy a lot of flight fun.
Quadrocopter for outdoor use
Higher weight and stronger engines are included quadrocopters available for the flight outdoors. You have a clear one more stable attitude and can not be easily disturbed by wind, whereby strong gusts are of course also clearly perceived with these models. There is for this type of Quadrocopter also still inexpensive entry-level models, whereby the price with the size and the equipment (for example, camera system) can also quickly rise to several thousand euros for ambitious hobby pilots. Similar to other remote-controlled models, it comes also to the scope of delivery. Most Quadrocopter be in complete Sets (RTF "ready to fly") delivered with all required components. The integrated camera systems often have the choice of image quality or resolution. Some models offer one HD resolution, other deliveryn 4K quality. With the camera systems, there is still the difference whether the images are transmitted in real time, for example on a display or FPV glasses, or stored on a memory card for later evaluation of the images. By a Real-time transmission of images is a control of the model based on the received image information possible, it is practically controlled as if the pilot sat in the Quadrocopter, The name is for it FPV what kind of "First person view" stands. In connection with FPV also a GPS system is mostly used. This allows further functions. By the GPS system, which is also used in navigation systems, can the Quadrocopter orient or navigation data can be transmitted. By means of this telemetry, for example, position or current altitude can be read off. Some models can even return automatically when leaving the transmission range, which increases the security very much, especially if long distances with the Quadrocopter be covered. Another feature offered by some models thanks to the GPS system. Here the transmission signal is automatically followed. For example, if the "pilot" is on a hike from his Quadrocopter filming.
Surely you will be with one Drone with camera unlikely to have much fun. Being able to look at nature from a bird's-eye view is not only a pleasure for nature lovers. Much of what is otherwise hidden can be viewed from above. With the popular FPV quadrocopter (first-person view) that is easily possible. The advantage is the easy operation, this is basically the case for models for outdoor and indoor use.
Quadrocopter can also be used for commercial purposes. For example, you can use them to monitor your property, find damage to buildings and keep an eye on commercial property. For monitoring and control, high-quality models prove to be ideal helpers. Do not forget the legal situation, because data protection and flight safety are always in the foreground when using a drone.
Models with camera support different output devices of the image material. Thus, a display on the remote control, a display glasses or even a connection for a display can be provided.
The entry-level models
Are you still inexperienced with flying one Quadrocopter, recommends a cheaper model for the first hours of flight, especially if children want to use it. The manoeuvrable and small models for interiors promise a lot of fun for all ages. Disadvantages of Entry-level models are some missing special features, limited flight times and a lack of camera equipment, but they also provide outdoors for a great recreational fun. They are extremely easy to fly and the price is cheap. Already for about 90, - Euro you will find a very well functioning to get started Quadrocopter before.
Decide before buying if a pure indoor model is desired. Outdoors, absolute calm is required for a flight.
Buying on the Internet or at the local dealer?
It is ideal before buying one Quadrocopters on the Internet to inform. Here you will find a large selection of products incl. Information. The decision where to buy your desired model you should always think well, because the prices here show great differences between online retailers and local retailers. We hope to help you with our information.
On site: models from the specialist trade
Model-making shops are not necessarily found in your area, so a longer journey would be necessary. Of course this is associated with additional costs and time. Especially annoying, if not even parking is available nearby. For some buyers, however, this does not matter because they value expert advice - the personal consultation. Unfortunately, these consultations are not always positive for the customer, as some sellers try to sell the stock drones, which are certainly not always true test winner. Many a shop keeper is represented as a top model. Bargains are hard to find in specialist shops. Models that are offered by discounters, usually only a short time for the fun.

A personal consultation does not take place, but this is not fundamentally objective and customer friendly. To a Return Policy You do not have to do without when buying online.
Advantages of quadrocopters to remote-controlled aircraft and helicopters
A Quadrocopter develops its buoyancy through the propellers (rotors). Compared to airplanes, which generate the lift only at a certain flow velocity on the wings, a Quadrocopter climb and land vertically, and stand in the air. So there is no minimum speed to be respected and no runway is needed. That's why some models can even be used indoors. Also camera shots benefit from the abilities of the Quadrocopter.
A remote-controlled helicopter comes the flight characteristics of a Quadrocopter very close. However, a helicopter works on other bases, which are more difficult to control. He has only one possibly two rotors, which are larger than at quadrocopters are. In order to carry out the different air movements, a helicopter needs mechanical components, for example a swashplate or adjustable rotor blades. Not only the structure is more complicated but also the operation. In addition, the rotors of helicopters are much larger than those of the Quadrocopter, In addition, care must be taken that the rotor blades nowhere abut. Even an extreme angle at the start of the helicopter can lead to the impact of the rotor blades on the ground, which usually equates to a destruction of the model. On Quadrocopter has four smaller rotors, which can even be encased with "protective cages". As a result, the rotor blades can strike nowhere anywhere. The flight movements arise at quadrocopters only by the different speeds of the individual motors. This makes their design easier and the operation is easier. Not infrequently catch even budding "pilots" remote-controlled helicopter once with quadrocopters
Quadrocopter can be produced inexpensively and do not necessarily require much space for a flight. As a result, they are at the top of the popularity of remote-controlled models. As a result, there are also increasing numbers Drones in the air. The legislator sees a danger in the increasing number of unmanned missiles, for which reason drone regulations were passed. These depend on the departure weights and are staggered accordingly. A small excerpt from it:
From a take-off weight of more than 250 grams, there is always a mandatory labeling, even on model airfields! Durable and legible as well as fireproof, must be the marking of the name and address of the user of the drone or the Quadrocopter to be inferred. From a take-off weight of more than 2 kg, in addition to the mandatory marking, a flight certificate is required, which must be repeated every 5 years. Basically, drones should not fly higher than 100 meters. For heights above, a waiver must be obtained from the Aviation Authority. It is important to stay away from no-fly zones, for example near airports, nature reserves, crowds of people or main roads. The flying over of foreign land requires the permission of the owner. For models with cameras, additional factors may be important. Just as strangers may not be arbitrarily filmed anywhere without their consent, the right to privacy naturally also applies to the use of camera drones.
It is therefore necessary to know or to check the exact and regional law situation before using one Quadrocopter is flown. In addition, the regulations are constantly being expanded, which must be informed as owner and user.
