Description

The FlySpark F4 V1 BLS 60A Stack combines a feature-rich flight controller with a high-current electronic speed controller in a unified 30.5×30.5mm mounting package. The flight controller leverages an STM32F405 processor and a high-precision ICM-42688-P IMU, providing a stable sensor foundation for acrobatic flight and autonomous navigation modes across multiple supported firmware platforms.

The integrated BLS 60A 4-in-1 ESC is built on BLHeli_S firmware, offering reliable bidirectional DShot support and efficient power management for demanding 5-inch and 6-inch freestyle or racing quadcopters. The stack’s electrical design includes a 6-pin connector for seamless integration with DJI’s digital HD FPV systems, eliminating the need for complex wiring.

Key Features

  • Advanced Flight Controller: Features the FlySpark F4 V1 board with STM32F405 MCU, six UARTs, and a DPS310 barometer for altitude hold and autonomous flight modes.
  • High-Current 4-in-1 ESC: Integrates a 60A-per-motor BLS ESC with BLHeli_S firmware, capable of handling 3S to 6S LiPo battery inputs for high-power setups.
  • Digital FPV System Integration: Includes a dedicated 6-pin cable and connector for plug-and-play compatibility with DJI O3 Air Unit and Vista systems.
  • Wireless Configuration: Onboard Bluetooth module enables wireless MSP connection for firmware updates, PID tuning, and OSD adjustments via mobile devices.
  • Robust Power Filtering: Comes pre-packaged with a 35V 1000uF low-ESR capacitor to minimize voltage spikes and ensure clean power to sensitive components.
  • Compact & Lightweight Build: Engineered with a 47.8x47.5mm footprint and weighing only 10.5g, optimizing space and weight for competitive FPV builds.

Applications

  • 5-inch and 6-inch FPV racing drones requiring a compact, high-performance FC/ESC stack.
  • Freestyle quadcopters utilizing DJI O3 Air Unit or Vista for digital HD video transmission.
  • Long-range or autonomous drone builds running INAV or ArduPilot firmware for waypoint navigation.
  • Heavy-lift or high-power cinematic drones needing robust 60A-per-motor current handling on 6S power.

Frequently Asked Questions

What is the maximum input voltage for the FlySpark BLS 60A ESC?

The integrated BLS 60A 4-in-1 ESC is rated for 3S to 6S LiPo battery inputs, corresponding to a voltage range of approximately 10.8V to 25.2V. Ensure your power wiring and connectors are rated for the high current draw associated with 6S operation.

How do I connect a DJI O3 Air Unit to this stack?

The stack includes a dedicated 90mm 6-pin DJI cable. Connect this cable from the designated 6-pin port on the flight controller to your DJI O3 Air Unit or Vista. This provides power, video, and data connectivity without requiring additional soldering.

Can I configure this flight controller wirelessly?

Yes, the integrated Bluetooth module allows for wireless MSP configuration. You can use compatible smartphone apps like the SpeedyBee app to adjust Betaflight settings, update firmware, and modify OSD layouts without a USB cable.

What firmware does the flight controller support?

The FlySpark F4 V1 flight controller is compatible with Betaflight, INAV, ArduPilot, EMU-flight, and SkyBrush firmware. The default firmware is typically Betaflight, and you can flash your preferred firmware via the USB Type-C port or Bluetooth DFU.

What is the mounting hole pattern and recommended hardware?

The stack uses a standard 30.5mm x 30.5mm mounting hole pattern with 4mm diameter holes. The package includes M3x30mm screws and M3 nylon nuts for secure installation into most 5-inch FPV drone frames with matching 30.5mm stack spacing.
