Drone plays a big role in the game of Rust, because it can scout the terrain before entering the battle, and significantly increase your chances of winning it. At the moment, only the drone is available for general use, with which you can order items, you can not control it. 
It appeared in the game in February 2021, but is still in the testing phase. There is also a drone that is only available by entering a console command, and it can be very useful. I suggest you consider the options for its use.

Drone capabilities.

The drone can send you a picture at long range, and is a good option for scouting. It can help you find crates and valuable loot. It will show you where enemies are and reveal their location. 
It can also be used in case you are attacked. You can find out which side the enemies are coming from, their number and weaponry. You can find it mostly from some crates and containers, but the chance of dropping it is very small, and at best is only 2%.
The important thing is that you can scout the enemy base for loot, inhabitants and buildings in the form of turrets and the like.

How to craft a drone?

You can create it only on workbenches of level 2 and 3. For this you will need 200 units of scrap metal, a video camera and 2 microchips.
To study it, you will need to find it, and study it on the research table. You can also spend a little more scrap metal and simplify your task by studying it in the corresponding branch. You will have to spend about 350 units.

How to control the drone? 

Control on it is simple and intuitive, but let's understand a little more in detail to remove unnecessary questions.

• Shift - gain altitude;
• Ctrl - lower altitude;
• WASD - control buttons.

Also keep in mind that the drone has a range of use. If it flies too far away, you can lose communication, and you will have to pick it up yourself. Also do not crash into obstacles, stay away from water, because with their help it can be easily destroyed.
