Flight controller SpeedyBee F405 V4 BLS 60A

Order the SpeedyBee F405 V4 BLS 60A flight controller - brains and power in one stack!

Flight controller SpeedyBee F405 V4 BLS 60A is an integrated solution for modern quadcopters. It combines a powerful flight controller and strong throttle controls. This ensures perfect consistency and performance of the entire system. You will receive a ready-made control center for racing and freestyle drones. This stack is designed for pilots who value clean builds and high performance.

This model continues the successful SpeedyBee product line. It offers updated components and improved performance. Integration of key modules simplifies installation and increases reliability. Your drone will be lighter, cleaner and easier to set up. This is a smart choice for building a new or upgrading an old device.

• Full integration of flight controller and ESC 4-in-1 for clean installation.

• High current regulators 60A with support for Dshot1200 protocol.

• Built-in Bluetooth and Wi-Fi module to configure via the app.

• Advanced F405 processor and a low noise gyroscope.

• Automatic calibration and optimized settings for a quick start.

How this integrated flight stack works

The flight controller (FC) processes the pilot's commands from the receiver. It also reads data from the gyroscope and accelerometer. The processor calculates the necessary adjustments to stabilize the drone. Commands are then sent to the built-in ESCs. They convert them into powerful three-phase current for motors.

Thanks to integration, communication between FC and ESC is instantaneous. This minimizes delays in power plant control. The overall system becomes smaller and less prone to interference. All settings can be made centrally through one application. This saves time and simplifies the setup process.

The technical characteristics of the stack indicate its high class. The flight controller uses an STM32F405 processor and a BMI270 gyroscope. Four speed controllers provide a continuous current of 60A per motor. Dshot1200, Oneshot, Multishot control protocols are supported. Operating voltage 2-6S (up to 25.2V) is suitable for most drones.

Functionality

The functionality of the device has been significantly expanded thanks to wireless modules. Built-in Bluetooth and Wi-Fi allow you to connect from your smartphone. You can configure Betaflight settings without a USB cable. Blackbox mode is also available for recording flight data. The built-in BEC provides stable 5V and 9V for powering peripherals.

The stack design is designed for efficient cooling. The boards are connected via massive contact pins for low resistance. High quality components are used, including tantalum capacitors. All this ensures stable operation under high load. Compact size and weight fits most racing frames.

Installing and configuring the stack is incredibly simple. You need to bolt it to the frame and connect the motors, receiver, camera and VTX. Next, preliminary configuration is performed through the SpeedyBee mobile application. The app offers step-by-step instructions for beginners. You will be able to get your drone airborne in no time.

This stack is ideal for racing and freestyle. It is designed for drones ranging in size from 3 to 5 inches. The 60A power is enough for the most popular motors 2207, 2306. Bluetooth integration is a huge convenience for quick setup in the field. You will be able to change the settings right before departure.
