And now let's look at the main characteristics of multi-copters.
----------------------------------------------------------------


**1) Size**

*Multi-copter can be divided into three main classes according to size:*

**Large drones** can lift rather advanced load and can fly for a distance of several kilometers.

**Average multi-copters** are most popular among users. It is a rather small vehicle, which can be carried in a backpack.

**Small and ultrasmall multi-copters** - are for beginners. These devices can be carried in a briefcase or even in your pocket. Due to the small size - these drones have problems with flight stability.

**2) Number of blades**
The most popular multi-copters on the market are quadcopters are vehicles with four blades, but you can also find drones with two, three, six and eight blades.

The power of the vehicle, as well as the stability of its flight, depends on the number of blades. 

**3) The principle and convenience of control** 

*WI-FI*


Most of the models of quadcopters can be controlled using a smartphone or tablet by connecting them via a wireless Wi-Fi communication. It's incredibly convenient because the control of the vehicle is carried out via a simple and intuitive interface and allows you to take photos with one touch.

But such control has a **significant drawback** - the device can fly from you only for a few dozens of meters.

*Special control panels*


They can increase the range up to several kilometers.


But the control process **becomes much more complicated** - panels have many additional features and 
capabilities that are not available on mobile devices.

*BUT*

Mobile devices can be combined with the "professional" management consoles of multi-copter. 

**4) Camera presence**

**In large multi-copters**, as standard in 90% of cases, there will be no cameras.

**Average multi-copters** are the best option, as they are sold with the built-in camera with a good resolution (megapixels 10-14).

**Small multi-copters** often have an inbuilt camera. But this is a fairly simple device with - 0.3 to 2 megapixels.

**5) Batteries**

Another important moment in choosing multi-copter. The average period of drone work is 8-15 minutes.
However, the problem of low capacity batteries in multi-copters can be partially solved by the use of replacement batteries.


----------
*If you want to buy a multi-copter then choose the size you need, then  decide how many blades do you want and compare prices for different models in a few shops in order to find the best offer (I recommend you to buy only vehicles with a remote controller)!*

*In addition, I want to say that this industry still grow really fast as the popularity of multi-copters and I get you all the instructions about them, so it is you turn to decide whether you want to be a part of this movement or not.*
