CrossRace Flight Controller

The RadioLink CrossRace is a compact and powerful flight controller for drones and advanced RC projects that combines features from ArduPilot/APM with the manual flight feel of Betaflight – for FPV pilots, builders and developers who want flexibility in a small format.

• Combines autonomous flight and manual mode – support for both PosHold and more direct manual control
• Integrated OSD module for displaying flight data in real time
• Support for DJI/CADDX HD digital video transmission via plug-and-play connection
• 12-channel output for flexible build projects
• Support for 4-in-1 ESC and ESC telemetry
• Software-based vibration damping for more stable sensor data
• Support for reprogramming and further development

Combines ArduPilot and Betaflight feel

The CrossRace offers both stable autonomous functions and a professional manual flight mode: PosHold keeps the drone stable when you need extra control, while manual control gives a more direct FPV experience. Automatic return to the launch point adds peace of mind during outdoor flying, for example on signal loss.

Support for development and customisation

The CrossRace supports reprogramming and further development, making it extra interesting for advanced users, educational environments and your own UAV projects. The source code is available via GitHub:

Stable flight with PosHold

Radiolink’s high-dynamic algorithm makes it possible to use PosHold even during more active flying – a good combination of stability and freedom of movement, especially for outdoor flying, aerial photography and longer FPV sessions.

Ready for HD video transmission

The CrossRace supports the DJI O3 and CADDX Walksnail Avatar HD Pro Kit via plug-and-play, and ready-made connector interfaces and solder pads make it possible to expand the system without it taking up more space.

Support for 4-in-1 ESC and ESC telemetry

The CrossRace has a 10-pin ESC connector with support for voltage and current monitoring and ESC telemetry, and supports common ESC protocols such as PWM, DShot and OneShot.

• Support for 4-in-1 ESC
• Support for ESC telemetry
• Support for PWM, DShot and OneShot
• Built-in dual BEC at 5 V and 12 V

Integrated OSD for FPV flying

The integrated OSD module shows key flight information directly in the video image without an external module. It can display flight mode, distance, GPS satellites, position, vertical speed, battery voltage, current, heading and vibration status.

Compact size with many features

At only 37 x 37 mm, the CrossRace fits even compact builds and still supports up to 12 output channels for several types of multirotor projects.

Software-based vibration damping

The CrossRace uses software-based vibration damping that filters out high-frequency vibrations for more reliable sensor data, better altitude hold and more stable flight, and can reduce the need for extra damping mounting frames in many builds.

Support for GPS, RTK and several mission planners

The CrossRace supports GPS and RTK, and parameters can be set via Radiolink Mission Planner, ArduPilot Mission Planner and QGroundControl. Together with the Radiolink GPS TS100, the system can benefit from dual interference protection technology and high positioning accuracy, depending on the installation and environment.

GeoFence for safer flight areas

The GeoFence function sets virtual boundaries for the flight, useful during training, long-distance flying and missions within a defined area. Always check current local drone regulations and flight zones before flying.

Quality assurance through automated testing

The CrossRace is tested with an automated software testing system that checks everything from sensors to ports and interfaces, giving consistent quality and higher reliability than manual testing alone.
