What are stacks for FPV drones and quadcopters?
A stack or flight controller is the brain of any quadcopter. It receives signals from the remote control, sensors, and camera, processes them, and transmits commands to the motors. In simple terms, without a drone controller, flight would be impossible, as it is responsible for stabilization, reaction speed, and movement precision.
Before launch, chargers are used to prepare batteries compatible with the system's parameters.
Purpose of flight controllers for drones and quadcopters
The flight stack coordinates the operation of all systems: from the gyroscope and accelerometer to the barometer and compass. It helps keep the drone in the air even in windy conditions, corrects pitch and roll, and ensures smooth flight. Modern flight controllers can also support OSD, transmit telemetry, and work with FPV systems in real time.
Signal stability is also affected by antennas, which must be correctly placed on the drone frame.
How to choose stacks for FPV drones and quadcopters?
When choosing a drone controller, pay attention to several points:
- Processor and microcontroller determine the speed of signal processing.
- Compatibility with the FPV video system is important for a high-quality, lag-free picture.
- Presence of sensors: barometer, gyroscope, and accelerometer. They determine flight stability.
- Current and input voltage – whether the flight stack can withstand the load from the battery.
- Firmware and frequency support, since the controller must be flexible for settings.
When choosing, also check that drone batteries match the stack's permissible voltage and current.

Frequently asked questions about products in this category Stacks (Flight Controllers) for FPV Drones and Quadcopters
A stack is a set of electronics that controls a drone and transmits commands to its motors. In FPV builds, this often refers to the flight controller alone, or a kit that includes the controller and a speed controller. In simple terms, the flight stack is responsible for how the drone stays airborne, responds to the remote control, stabilizes after maneuvers, and interacts with other modules.
A flight stack typically consists of a flight controller and an electronic speed controller. The controller processes signals from the remote, gyroscope, accelerometer, and other sensors, while the speed controller delivers the correct power to the motors. In some builds, the stack also includes a power distribution board, a barometer, a black box for data recording, a telemetry module, or connectors for a video system.
A flight controller is a board that manages a drone's behavior in the air. It receives commands from the remote control, reads data from sensors, and constantly adjusts motor operation to prevent the drone from tilting or losing stability and to ensure it responds properly to stick movements. The controller determines control precision, reaction speed, flight mode operation, telemetry, and firmware compatibility.
An electronic speed controller (ESC) manages motor RPMs. It receives commands from the flight controller and adjusts power to each motor individually. If the ESC is too weak for a specific build, it can overheat, fail to handle the current, or perform unstably under load. Therefore, when choosing an ESC, consider current rating, battery support, firmware, cooling, and load margin.
An AIO stack is a board that combines a flight controller and an electronic speed controller (ESC) into a single module. This option is well-suited for compact builds because it occupies less space and is easier to install. A standalone FC is just a flight controller, with the ESC selected separately. An FC+ESC stack is a set of two boards that are mounted one above the other: a separate controller and a separate ESC. This format is more often chosen for more powerful FPV drones that require a better current reserve and easier repairs.
The stack may include a barometer, gyroscope, accelerometer, black box, voltage stabilizer, power distribution board, telemetry, and connectors for a video transmitter, camera, receiver, and GPS. Not every stack includes everything, so before choosing, it's better to check what is actually needed for a specific drone. For racing, quick response is important; for longer flights, telemetry, power, port availability, and stable navigation are key.
Modern stacks often use STM32 F4, F7, or H7 processors. F4 is a common option for many FPV builds, F7 provides more headroom for complex settings and additional modules, and H7 is used in more powerful controllers. The processor affects command processing speed, firmware support, number of functions, and how comfortably the stack works with sensors, ports, and telemetry.
Drone stacks in Ukraine are priced from 95 UAH for individual boards and auxiliary elements in this group. If we are talking specifically about flight controllers, prices start from 1,440 UAH, and ready-made FC+ESC stacks start from 2,760 UAH. Further cost depends on the processor, ESC current rating, 4S/6S/8S support, number of ports, presence of a black box, barometer, telemetry, and package contents.
You can order drone stacks from Flash Army — either separately as a flight controller, speed controller, or as a ready-made FC+ESC kit. Here, it's convenient to select electronics to match your frame, motors, battery, video system, and desired build format, avoiding incompatibility issues during assembly. Orders are shipped quickly across Ukraine so that you can receive the necessary components without long waits.
