Description

The CrossRace Pro flight controller is engineered for demanding applications such as high-speed FPV racing, autonomous navigation, and professional aerial platforms. Its core architecture combines a powerful HC32F4A0PITB MCU with a high-performance BMI270 IMU, delivering stable attitude estimation even in dynamic flight conditions. The integrated SPL06 barometer provides accurate altitude hold, essential for waypoint missions and position hold modes.

Electrical design prioritizes clean power delivery and system integration. The dual-switching BEC circuits ensure stable 5V and 12V rails, capable of powering sensitive peripherals like GPS modules, digital HD systems (e.g., DJI O3 Air Unit), and telemetry radios without noise interference. The controller’s 12 output channels and multiple serial ports offer extensive connectivity for peripherals, supporting protocols like SBUS, PPM, and SmartPort telemetry.

Key Features

  • Advanced vibration damping algorithms filter high-frequency motor and frame vibrations for smoother flight performance.
  • Built-in OSD module eliminates the need for an external unit, displaying critical flight parameters directly in FPV feed.
  • Supports 4-in-1 ESC telemetry protocols (DShot, PWM) for real-time motor current, RPM, and temperature monitoring.
  • Open-source ArduPilot firmware compatibility enables advanced customization and autonomous flight mission planning.
  • Geo-fencing functionality helps pilots comply with local flight regulations by defining virtual boundaries.
  • Wide operating temperature range (-30°C to 85°C) ensures reliability in extreme environmental conditions.
  • USB Type-C interface provides robust connectivity for configuration, firmware updates, and data logging.
  • Compact, lightweight design minimizes airframe weight, making it ideal for high-performance racing and freestyle builds.

Applications

  • High-performance 5-inch and 7-inch FPV racing drones requiring precise control and low-latency response.
  • Autonomous mapping and surveying platforms utilizing ArduPilot for waypoint navigation and geo-fencing.
  • Long-range freestyle and cinematic drones where stable flight performance and integrated OSD are critical.
  • Custom multirotor builds (2-8 axis) including hybrids and fixed-wing VTOL platforms.
  • Professional aerial photography rigs integrating digital HD video systems (DJI O3, Walksnail) and GPS modules.

Frequently Asked Questions

What is the input voltage range for the RadioLink CrossRace Pro flight controller?

The controller itself is powered via its BEC inputs from a LiPo battery. The integrated dual BECs provide regulated 5V and 12V outputs for peripherals. The main board is designed to handle typical LiPo voltages used by the connected 4-in-1 ESC (e.g., 2-6S). Always confirm your specific ESC's voltage compatibility.

Does the CrossRace Pro support ExpressLRS receivers?

Yes, the CrossRace Pro supports ExpressLRS receivers via its serial RX ports using protocols like CRSF. You would connect the ExpressLRS receiver's TX pin to a dedicated UART RX pad on the flight controller and configure the corresponding port in the firmware for serial-based receiver protocol.

Can I use this flight controller with Betaflight firmware?

The CrossRace Pro is primarily designed and documented for use with ArduPilot firmware, which supports its advanced features like geo-fencing and extensive telemetry. While the HC32 chip may be flashable with other firmware, full feature compatibility with Betaflight is not guaranteed. For FPV racing-focused builds, a Betaflight-native FC is recommended.

What mounting hole pattern does the CrossRace Pro use?

The RadioLink CrossRace Pro uses a standard 30.5mm x 30.5mm mounting hole pattern (M3 holes). This is compatible with most modern FPV drone frames and stack mounting configurations.

How do I connect a DJI O3 Air Unit or other digital VTX to the 12V BEC?

The 12V BEC output pad on the CrossRace Pro can directly power a DJI O3 Air Unit or similar digital VTX that requires ~12V input. Ensure you use appropriate gauge wiring and confirm the current draw of your VTX does not exceed the BEC's rated current capacity. Always connect power and ground correctly to avoid damage.
