In the world of UAVs, every component is important. Yet there are some that remain little-known, despite their key role in overall aircraft performance. This is particularly true of the ESC (Electronic Speed Controller). Without it, it's impossible to fly a modern drone, whether it's a hobby aircraft, an FPV drone or a professional platform.
In this article, we'll look at what an ESC is used for, its role in the drone's electronic architecture, the criteria to consider when choosing one, and the concrete advantages of theCenturion ESCdesigned by Drone Français. A real technological brick made in France, designed for reliability and performance.
What is an ESC and why is it essential in a drone?
An ESC (Electronic Speed Controller) is an electronic component responsible for controlling the speed, direction of rotation and sometimes even braking of a brushless motor. In short, it's the interface between the flight controller and the drone's motors.
Its role is to translate flight controller commands into electrical signals adapted to each motor. These commands may concern acceleration, deceleration or stabilization of the drone in flight. Without ESC, there would simply be no way to control the speed of the motors or to fly in a stable manner.
For a multi-rotor drone, each motor usually requires a dedicated ESC. This is why 4-in-1 ESCs have become very popular, especially in FPV drones, as they integrate four controllers into a single compact board.
How does an ESC work in a drone?
The ESC is connected between the battery and the motor. It receives electrical energy from the battery (usually direct current) and converts it into the three-phase alternating current required to operate brushless motors. This conversion is made possible by a microcontroller integrated into the ESC, capable of rapidly interpreting signals from the flight controller.
Precise operation depends on several parameters:
- Communication protocol : signals between the flight controller and the ESC can use different protocols, such as PWM, Oneshot, Multishot or even DSHOT (faster and more precise).
- Motor timing : the frequency at which signals are sent influences motor response.
- Built-in algorithms : some ESCs use optimized firmware to improve responsiveness and reduce power consumption.
High-quality ESC ensures that the drone responds quickly and smoothly in flight, which is essential for stability and maneuverability.
How do you choose the right ESC for your drone?
The choice depends directly on the type of drone you want to build or repair. Here are the most important criteria:
Maximum supported current
Each motor draws a certain current, in amperes (A). It must be able to withstand this current without overheating or damage. For example, a 65A ESC means it can deliver up to 65 amperes continuously to each motor.
Compatible input voltage
The input voltage (expressed in number of battery cells, e.g. 3S, 4S, 6S...) must be compatible with the rest of the drone's electronics. An ESC that supports from 3 to 6S is compatible with batteries from 11.1V to 22.2V.
ESC type: individual or 4-in-1
For small FPV drones, they are very practical, reducing wiring and weight. For larger or modular drones, individual ESCs can offer greater flexibility.
Additional functions
Some ESCs include advanced features such as :
- a current sensor (useful for telemetry),
- thermal protection (to prevent overheating),
- optimized firmware (like BLHeli_32 for performance).

Why trust the Centurion?
Reliability made in France
Unlike many ESC products produced abroad, Centurion is designed, manufactured and tested in France. This complete control of the production chain means better quality control, responsive after-sales service, and a genuine partnership with users.
Robustness and endurance
With a continuous current of 65A per channel (and up to 75A at peak), the Centurion is capable of powering the most powerful UAVs without fear of overheating or power cuts. It's a component built for endurance and performance.
Format optimized for FPV
Its 4-in-1 format saves considerable space in the chassis, which is crucial in compact, agile FPV drone set-ups. It helps to lighten the machine without sacrificing power.
A real technological brick
L'ESC Centurion is much more than just a controller. It's a technological brick that contributes to the overall optimization of the drone. Its modern firmware, internal protections and integrated current sensor make it an intelligent performance tool.
What type of UAV is the Centurion best suited for?
L'ESC Centurion is designed primarily for :
- High-performance FPV freestyle or racing drones ,
- Compact professional drones used for filming or inspection,
- Custom projects requiring reliable, high-end electronic components.
It can be fitted to a light but responsive drone, as well as to a more robust chassis designed for technical missions.
An essential part not to be neglected
In the drone world, they are often overshadowed by the motors, cameras or flight controller. And yet, without a good ESC, no maneuver can be performed with confidence.
precision. It's a vital component that directly conditions responsiveness, stability and flight safety.
