The specifications of these important parameters of the flight control are (when you buy) to be considered.
- BEC output
The core of the flight controller, referred to as the MCU or processor, operates as the nerve center for input and output operations. Occupying a prominent spot on the flight controller, the MCU is often recognizable as a sizable black square, sometimes featuring visible pins protruding from its edges. A prevailing choice for FPV drones is the STM-32, a prominent player within the STM32 family.
The STM32 series is categorized into distinct families denoted by alphanumeric combinations. The current market showcases FC MCU processors in three major variants: F3, F4, and F7, with F4 and F7 reigning as the mainstream choices.
To delve into the nuances between F4 and F7, you can explore ST’s comprehensive catalog titled “STM-32 High Performance MCUs.”
Observing the offerings on major FPV dealers’ platforms, it’s evident that flight controllers equipped with F7 processors have gained prevalence over those sporting F4 processors.
Functioning as a pivotal component, the gyroscope, nestled within the vehicle, furnishes crucial data to the flight controller concerning the quadcopter’s movements. This input is integral to the quadcopter’s seamless operation. Delving into gyro parameters, one will encounter designations such as MPU6000, ICM20608, and even BMI270 on various flight controllers. While the MPU6000 boasts a legacy of stability, its update rate caps at 8k. On the other hand, ICM gyros can reach an impressive 32KHz; however, they exhibit heightened sensitivity to vibrations generated by motors or propellers. As a result, the MPU6000 remains the reigning preference for mainstream usage.
For an in-depth exploration of the disparities between MPU6000, ICM20608, and BMI270, consider perusing the informative video shared by Chris Rosser on YouTube.
Upon the culmination of your build, navigating the realm of FPV firmware is imperative. Some FC firmware is tailored for optimizing stock flight performance in race and freestyle scenarios, while others extend their capabilities to autonomous GPS flights. Although an elaborate dive into autonomous GPS flight firmware is beyond the scope here, the focus rests on FPV firmware tailored for race and freestyle flight.
a prominent name in the realm of FPV firmware, provides a robust solution for enhancing the flight experience. Recognized for its versatility, Betaflight caters to both racers and freestyle enthusiasts, delivering tailored configurations to optimize performance.

Electronic Speed Controllers (ESCs) are integral components that govern the motor’s RPM based on directives issued by the flight controller. During the nascent stages of FPV, ESCs were distinct entities, but the landscape evolved with the emergence of 4-in-1 ESCs, which debuted around 2015.
In contemporary times, 4-in-1 ESCs have assumed the mantle of mainstream prevalence within the market. Their ascension has brought forth numerous advantages, including an expansive array of replacement options and simplified repair procedures. This shift has engendered heightened convenience for FPV enthusiasts. Opting for split ESCs presents a different scenario, with a diminished pool of selections available. Furthermore, the task of mending or substituting split ESCs is notably less straightforward.
The transformative journey of ESCs reflects the dynamic evolution of FPV technology, enhancing both the flight experience and the accessibility of maintenance and upgrades.
A more basic introduction to FPV ECS is available here post：FPV drone components-ESC
When you are choosing ESC, some specifications to consider:
- Continuous Current & Burst Current
- Power Input
- Processor & Firmware
Continuous Current & Burst Current
Ensuring optimal performance, it’s imperative that the ESC’s continuous current rating surpasses 10 – 20% of the motor’s continuous current capacity. This precautionary measure effectively prevents overheating and introduces a margin for maneuvering, particularly during instances of maximum throttle utilization. Moreover, the Burst current specification emerges as a pivotal parameter, acting as a safeguard against potential burnout scenarios in the event of intense drone operations.
The significance of these two parameters extends to the judicious selection of ESCs tailored to diverse drone sizes. Consider, for instance, a 3-inch FPV drone build, where the recommendation leans toward a 35A-40A ESC. Stepping up to a 5-inch freestyle FPV drone, an ESC within the range of 45A-50A is the recommended choice. As for a 5-inch racing FPV drone, an ESC boasting a 60A capacity emerges as the apt selection.
Appreciating the nuances of continuous and burst current parameters aligns harmoniously with the quest for optimal drone performance. These considerations remain pivotal when curating the perfect ESC for an array of drone sizes, underpinning a seamless marriage between power and control in the realm of FPV flight.
The power input aspect of ESCs is contingent upon the battery’s voltage capabilities, particularly in relation to higher voltage batteries. In the realm of 5-inch drones, the prevailing trend leans toward 3-6S batteries, encapsulating a wide range of power options.
Processor & Firmware:
The firmware that governs ESC operations is the essence of the BLHeli series. Notably, BLHeli_32 signifies firmware tailored for ESCs equipped with 32-bit MCUs, while BLHeli_S is optimized for those featuring 8-bit MCUs. Given its nomenclature, BLHeli_32’s applicability is apparent and remains dominant within the market. Delving into the distinctions between BLHeli_32 and BLHeli_S, a comprehensive video resource awaits for further insights.
This communication protocol serves as the vital conduit connecting the flight control system and ESC, facilitating the exchange of critical information such as throttle commands and motor speed data.
Prominent protocols encompass Oneshot125, Multishot, DShot600, and DShot1200. While Oneshot and Multishot rely on analog signals like PWM for transmission, DShot operates through digital signals. The inception of the DShot protocol traces back to its proposal by Felix within the KISS framework, subsequently embraced by the Betaflight and BLHeli_S development teams.
DShot’s ascendancy can be attributed to its hallmark traits of precise transmission signals and heightened reliability. The protocol’s superior attributes have led to its widespread adoption across the ESC landscape, underscoring its growing prominence within the field.
The same as mentioned above in Flight Control.
- 30.5×30.5mm,M3 for 5 inch drone
- 20x20mm,M2 for 3-5 inch drone
- 25.5×25.5mm,M2 for under 3 inch drone / Toothpick
- 16x16mm,M2 for under 2 inch drone
In the realm of motors, there exist two distinct categories: brush motors and brushless motors. Brush motors employ brushes for toggling between positive and negative poles, introducing resistance into the equation. This configuration results in lower efficiency, elevated motor temperatures, and a comparatively shorter lifespan.
On the other hand, brushless motors necessitate collaboration with brushless Electronic Speed Controllers (ESCs). This alliance yields enhanced efficiency, although it comes at a relatively higher cost compared to brush motors. The realm of brushless motors garners recognition for its prowess in delivering superior performance, balancing the scales between efficiency and expense.

Components of the drone motor.
Material of Motor
There are two types of high-temperature arc magnets: N52SH and N48SH. N48 magnets are commonly used in 4/5S battery 5-inch freestyle drones, while N52 magnets are preferred for 6S battery 5-inch racing drones due to their increased power and responsiveness.
When it comes to shafts, you have a choice between sturdy steel shafts and lightweight titanium alloy shafts. Bearings are also crucial, with Japan’s NSK bearings being a reliable and high-quality option. These components play a key role in ensuring optimal performance and durability for your drone.
Meaning of Motor Model
Let’s use the 2407 1700KV motor as an example. The numbers in the name give us important information about the motor’s size and performance.
The “2407” tells us about the motor’s dimensions. The first two digits, “24,” represent the diameter of the stator, which is like the core of the motor. The last two digits, “07,” tell us about the height of the rotor, which is the spinning part of the motor.
The “1700KV” is a value that tells us about the motor’s speed. The higher the KV value, the faster the motor can spin. So, in this case, the motor has a KV rating of 1700, which means it can spin pretty quickly.
If you’re wondering about the best brushless motor for your FPV setup among the various options, you can narrow down your selection by considering factors such as motor size, KV value, and thrust capability. Let’s break down these aspects step by step to help you make an informed choice.
What is the difference between 2206 and 2207 or 2306?
Stator = diameter = 22mm
Rotor = height = 6mm;
The wider the diameter, the greater the torque, the higher the height, the faster the speed. So the larger the diameter the more violent.
When crafting a 5-inch drone, your optimal choices lie within the 22 series and 23 series models. It’s important to note that the thrust rating is determined solely by the motor model, not the KV value. Consequently, the order follows this sequence: 2204 < 2205 < 2206 < 2207 < 2208 < 2306 < 2307 < 2407. This ranking delineates the progression of violence, aiding in your decision-making process for your drone’s performance optimization.
2206 2400KV and 2207 1800KV or 2306 2450KV What is the difference between these KV values?
the KV value defines the number of rotations a motor can complete in one minute under a specific condition—without a load (no propeller) and with a consistent current of 1 volt. Essentially, KV signifies the motor’s rotational speed.
Calculating the maximum speed entails multiplying the voltage by the KV value. For instance, if the KV rating is 2300 and the voltage is assumed to be 14.8, the result would be 34,040 revolutions per minute.
It’s crucial to note that while a higher KV value suggests greater speed potential, excessive power can lead to motor burnout. Thus, when selecting a motor, it’s vital to pair it with an appropriate propeller to optimize force efficiency and ensure safe operation.
Remember: High kv value need to match the “small” propeller, Low kv value need to match the “large” propeller.
The terms “large” and “small” pertain to the propeller’s size and pitch, specifically indicated by the two numbers following the propeller type. For instance, in the context of 22-23 series motors, the optimal choice is a 5-inch propeller. When working with a high KV value and a smaller propeller, this typically refers to propeller types like 5040, 5043, and 5046. Conversely, larger propellers are denoted by types such as 5146, 5143, and 51466.
This distinction between “large” and “small” propellers plays a significant role in optimizing the performance of motors, ensuring an appropriate match between motor characteristics and propeller specifications.
The measurement of thrust in an electric motor is typically expressed in grams and is subject to fluctuations based on both the motor’s rotational speed and the propeller’s spinning motion. This concept can be likened to the generated wind force resulting from rotation. In essence, the greater the thrust, the more formidable the wind force produced.
Selecting motors for racing and freestyle involves considering the KV value and battery compatibility. Racing motors usually have a KV under 2000, while freestyle motors are typically above 2000 KV. Motors under 2000 KV are often matched with 6S batteries.
For instance, a 2306 motor with 1850 KV might not provide enough power when used with a 4S battery. This emphasizes the need to align motor and battery specifications to achieve the desired performance level in racing or freestyle applications.
4.1 Recommended FPV Drone Motors
The 2207 2750KV motor is designed for frames with a 16x16mm motor hole. Weighing 31.4g, Despite the slight weight increase, the motor’s redesigned bell ensures exceptional durability and performance. Its responsiveness is commendable, making it a standout choice in its category.
Propellers play a vital role in keeping your multicopter airborne and significantly influence its flight dynamics. Making the right propeller choice is crucial, as the wrong one can lead to drone instability, battery drain, motor burnout, or even a crash.
Given that outdoor flights can often soil or damage propellers, they are frequently replaced components. Propellers need to be installed in a specific arrangement, with both clockwise and counterclockwise props. These counteract rotational forces, ensuring the drone’s stable flight path.
Propellers are typically identified using numbers indicating size, pitch, and blade count, such as Size (inches) X Pitch (inches) X Number of Blades. When you’re in the market for propellers, these parameters are the key factors to consider during your selection process.

5.1 Recommended FPV Props
Crafted for high-speed, agile flights, this propeller tips the scales at a mere 4.2 grams. Sporting a narrower width, it thrives at elevated RPMs. MCK, a key figure in propeller development, attests that the V2 version delivers improved grip and smoother flight traits.
Remarkably lightweight, the propeller doesn’t compromise on durability. If bent, you can often bend it back into shape for continued flight. Tailored for freestyle and indoor racing, it’s a top choice for those seeking nimble maneuvers and resilient performance.
6.Receiver & Radio Transmitter
A receiver is a device that can catch commands sent by a radio transmitter. It then works with a flight controller to understand these signals, which are turned into specific actions for the drone to follow.
Typically, a receiver comes with two antennas for 2.4GHz frequency. To get the best signal, it’s suggested to attach them to the drone at a 90-degree angle from each other.
FPV receivers are usually uncovered, without a box. They’re small, wrapped in plastic film or heat shrink. These uncovered RX devices are lightweight and can be easily placed in the limited space of the drone’s frame.
There are two main types of receiver protocols: analog and digital.
Analog Protocols – PPM and PWM
PPM and PWM were some of the initial protocols used in the UAV industry. Both PPM and PWM involve analog communication.
Digital Protocols – SBUS, IBUS, XBYUS, CRSF, DSMX
Different radio brands use various digital protocols for communication:
- Futaba and Frsky radios use SBUS protocol.
- Flysky radios use IBUS protocol.
- JR radios use XBYUS protocol.
- Crossfire modules use CRSF protocol.
- Spektrum radios use DSMX protocol.
Usually, the receiver and the radio need to be from the same brand to work together, ensuring compatibility. However, some receivers might use the same protocol even if they’re not from the same brand. This can be helpful when building a second drone.
Additionally, the frequencies of the receiver and transmitter must match. For instance, a 2.4GHz transmitter should be paired with a 2.4GHz radio receiver.
6.2 Radio Transmitter
The transmitter is the gadget responsible for controlling the drone’s movement and speed. It sends signals or commands to a radio receiver (RX) connected to the remote control. A majority of RC transmitters operate on the widely used 2.4GHz frequency. Both the receiver and remote control are paired and have automated frequency tuning, but they don’t automatically locate open channels.
Several factors come into play when you’re ready to buy a radio transmitter.
- Remote control mode
- Open TX

The battery acts as the primary power source for FPV flights, much like how a gas car requires oil to function. Let’s delve into the battery’s composition and key specifications to make informed battery purchases.
Battery “S” Rating – An FPV battery is made up of individual cells connected in series. For instance, 5S indicates the battery comprises 5 cells in series. Different FPV models necessitate batteries with varying “S” ratings. For instance, tinywhoop drones might require 1S or 2S batteries, freestyle FPV typically opts for 4S or 5S, while racing FPV often employs 6S batteries.
|NUMBER OF LIPO CELLS||NOMINAL BATTERY VOLTAGE|
mAh Rating – This indicates the battery’s capacity. For a general 5-inch FPV drone, a battery with a capacity of 1300-2000 mAh is commonly used.
Battery “C” Rating – This reflects the battery’s discharge capability. When seeking robust power, opt for batteries with higher “C” ratings. Experienced fliers often choose batteries with over 100C, but newcomers need not prioritize excessively high “C” ratings. Adequate is typically sufficient.
Battery Wiring – The battery features two wires: red for the positive pole and black for the negative. 5-inch FPV drones use XT60 connectors for the battery, while micro and cinewhoop drones use XT30 connectors. Another set of wires is the battery balance lead.
There are various LiPO battery connectors available. The widely used yellow XT60 connector is compatible with around 95% of 220mm-sized quadcopters powered by 3S-6S LiPO FPV Drone Batteries. The JST-XH connector is common in micro drones like the Tiny Whoop, offering better current flow than the smaller JST-PH connector. Here are the most popular battery connectors in a table for your reference:
|CONNECTORS OF TYPE||RECOMMENDED CELLS|
How to Purchase Batteries
Currently, batteries in the range of 1000-2000mAh are most common in the market, followed by 500-1000mAh, and then 300-500mAh. Opt for a battery that suits your drone’s needs. For instance, a 210mm wheelbase 5-inch FPV drone usually pairs well with a 1500mAh battery, while 2.5-3-inch FPV drones tend to use batteries in the range of 450-850mAh. For tailored advice on battery selection, you can refer to this post.
- Avoid leaving batteries fully charged or excessively depleted for extended periods, as this can lead to bulging or damage. If you plan to store a battery for a while, use the “storage” charging option to reach a voltage suitable for prolonged storage.
- While flying FPV, ensure not to over-discharge the battery. Keep an eye on the power level, and land when it drops below approximately 3.7V per cell.
- Outdoors, you can use a larger battery connected to a charger as a power source to recharge smaller batteries.
