A flight controller (FC) is a small circuit board of varying complexity. Its function is to direct the RPM of each motor in response to input. A command from the pilot for the multi-rotor to move forward is fed into the flight controller, which determines how to manipulate the motors accordingly.
What is a flight controller in a drone?
The flight controller (a.k.a FC) is the brain of the aircraft. It’s a circuit board with a range of sensors that detect movement of the drone, as well as user commands. Using this data, it then controls the speed of the motors to make the craft move as instructed.
Can a drone fly without flight controller?
Yes. A Quadcopter can fly without sensors. The Quadcopter without sensor will be like something that you need to keep controlling.
How does a Quadcopter Flight controller work?
How A Quadcopter Flies. Basically, the movement on the remote control sticks, sends signals to the central flight controller. This central flight controller sends this information to the Electronic Speed Controllers (ESCs) of each motor, which in turn directs its motors to increase or decrease speed.
Which microcontroller is used in drones?
Drone and the microcontroller (Figure 10). The microcontroller we used is an ATMEL ATmega 1284 8-bit microcontroller. It runs at 14,7456 MHz, has 128 Kb of memory, 32 I/O pins, counters and timers with PWM capabilities as well as two USART ports and a 10-bit ADC.
How are military drones controlled?
Pilots rely on satellites to track drones. From takeoff until it leaves the line of sight, the drone is controlled with a direct data link from a ground-control station. If the communication link is lost, the drone is programmed to fly autonomously in circles, or return to base, until the link can be reconnected.
What happens if you fly a drone above 400 feet?
If you attempt to fly beyond this limit, the drone will simply stop gaining any more altitude and just hover in place. The problem with this approach is that it doesn’t take into consideration the presence of any large structures within 400 feet of the drone which would have allowed drone flight beyond 400 feet.
What happens if drone goes out of range?
What happens when a drone flies out of its range? Drones have a limited range. When the drone is flying out of that range, then the signal you need to control the drone is lost. Therefore you can no longer control the drone.
Can a drone fly with 3 propellers?
It is possible to fly with three propellers. Thing is, you must approach the design almost as if this is a helicopter. Each of the props can provide lift, unlike a traditional helicopter, but one of the props must counteract spin.

What is the principle of drone?
Working Principle of Drones -Multi rotor
Multi-Rotor works on relative nature of force, that means when the rotor pushes the air, the air also pushes the rotor back. This is the basic principle that the Multi-Rotor can go up and down. Furthermore, the faster the rotor rotates, the greater the lift, and vice versa.
What materials are used for drones?
Top materials used in drones:
- Carbon fiber-reinforced composites (CRFCs)
- Thermoplastics such as polyester, nylon, polystyrene, etc.
- Lithium ion batteries.
