Foxeer Reaper F4 128K 65A BL32 4in1 ESC Controller for Drones 9~40V 30.5x30.5mm

When building a drone, you cannot do without a high-quality ESC (Electronic Speed Controller). This small but crucial component regulates the motor's RPM, thus affecting the overall performance and stability of the flight. In this article, we'll take a look at one of the best ESCs on the market – the Foxeer Reaper F4 128K 65A BL32 4in1 ESC. We’ll explore its features, technical specifications, and the advantages it brings to your drone setup.

What Does "ESC" Mean and How Does It Work?

ESC stands for Electronic Speed Controller, which is a device that connects to the drone's motor. Its job is to convert signals from the flight controller to the motors to regulate their RPM. This means the ESC determines how fast the motor spins, and in turn, affects the drone's behavior in the air. Without a quality ESC, your drone wouldn’t function properly, whether it's flight stability, speed, or precision.

Foxeer Reaper F4 128K 65A BL32 4in1 ESC Specifications

One of the most interesting models on the market is the Foxeer Reaper F4 128K 65A BL32 4in1 ESC. This ESC excels in several key parameters, which we will break down:

• 128K means the ESC uses firmware that processes up to 128 kHz, providing greater precision and efficiency compared to lower values.
• BL32 refers to the support for BLHeli32 firmware, which is a very popular and powerful software for ESCs.
• 4in1 means it combines four separate ESCs into one module, saving space and simplifying installation.
• 65A is the continuous current rating, meaning this ESC can handle up to 65A without overheating, making it ideal for high-powered motors and demanding flight conditions.

Input Voltage and Battery Compatibility

One important feature of this ESC is the input voltage range of 9V~40V, which means it is compatible with various batteries, from lower voltage ones to stronger 8S batteries. This wide voltage range provides flexibility when choosing a battery and ensures the ESC will work seamlessly with different configurations.

Performance and Current Load

In terms of performance, the Foxeer Reaper F4 can handle up to 65A continuous current per channel, which means it can support very powerful motors and high performance demands. In the case of burst loads, this ESC can handle up to 100A, which is really high for demanding situations like rapid acceleration or high speeds.

Telemetry and Signal Support

Another benefit of this ESC is telemetry support, meaning you can monitor data about the ESC’s status during the flight (such as temperature, voltage, or current). This feature is especially useful for racers and professionals who want to keep track of every detail.

It also supports various signal types such as DShot 150/300/600/1200, MultiShot, and OneShot, ensuring fast and reliable data transfer between the ESC and the flight controller.

ESC Programming Features and Options

When it comes to programming, the Foxeer Reaper F4 uses the BLHeli32 firmware, a highly advanced software for controlling ESCs. This firmware allows for fine-tuning settings, which is crucial for optimal performance and stability. With BLHeli32, you can adjust settings such as auto-calibration, PWM frequency, and brake mode, enabling you to customize the ESC to your specific needs.

Operating Temperature and Humidity

Speaking of temperature, the Foxeer Reaper F4 is designed to operate in a wide range of temperatures, from -20℃ to +55℃, which means it's suitable for all weather conditions, whether you're flying in summer or winter.

Regarding humidity, the ESC is designed to work in conditions with humidity ranging from 20% to 95%, which makes it ideal for flying in various environments.

Size and Mounting Holes

The dimensions of this ESC are 42.5 x 42 x 5.5mm, which is a standard size for most drones. With 30.5 x 30.5mm mounting holes and 4mm/M3 hole diameter, installing this ESC is quick and easy.

Weight and Its Effect on Performance

Weighing only 14.8g, this ESC is very lightweight, meaning it won’t unnecessarily burden your drone. Every gram counts, especially when building a racing drone, where every extra gram could make the difference between victory and defeat.

No BEC and How It Affects Your Build

The Foxeer Reaper F4 lacks a BEC (Battery Eliminator Circuit), meaning it won't supply power to servos or other components. This model is designed for advanced builders who already have an external BEC for powering other components.

Practical Use of the Foxeer Reaper F4

This ESC is ideal for racing drones or for those who need high performance and precision. With its high current rating and support for various signal types, it is suitable for demanding flights.

Comparison with Other ESCs on the Market

Compared to the competition, the Foxeer Reaper F4 stands out as one of the best ESCs in this category, excelling not only in performance but also in reliability and programmability.

Advantages of the Foxeer Reaper F4

Key advantages of this ESC include its excellent price-to-performance ratio, support for telemetry, and wide compatibility with different types of batteries and motors.
