RadioLink CrossRace Pro Flight Controller
The RadioLink CrossRace Pro is a compact, advanced Flight Controller for FPV drones, multirotor builds and UAV projects. It combines the autonomous flight functions of ArduPilot/APM with a more direct manual flight feel, suiting experienced pilots, developers and serious hobby builders alike.
- Pro version of the CrossRace with a more powerful STM32H743 processor
- 480 MHz processor and 1000 Hz scheduling frequency
- Combines autonomous flight and manual mode – stable PosHold and responsive control
- Support for parameter encryption
- Controllable 12 V BEC for video transmission, for example
- Integrated OSD module for real-time flight data
- Support for DJI/CADDX HD digital video transmission via plug-and-play
- 12-channel output for flexible multirotor builds
- Support for 4-in-1 ESC and ESC telemetry
- Software-based vibration damping for more stable flight
What sets the CrossRace Pro apart from the CrossRace?
The CrossRace Pro keeps the compact form factor and popular features of the standard CrossRace, but is built for more advanced installations needing higher processor performance, parameter encryption and extra control over the power supply.
- More powerful processor: The CrossRace Pro uses the STM32H743 at 480 MHz, while the CrossRace uses the HC32F4A0PITB.
- High scheduling frequency: The Pro version has a 1000 Hz scheduling frequency for fast, stable handling of the system's functions.
- Parameter encryption: The CrossRace Pro supports parameter encryption, which suits users who want to protect or lock important settings.
- Controllable 12 V BEC: The Pro version supports controlling the 12 V BEC via the transmitter, handy for video transmission, for example.
- Same convenient form factor: Both models have a compact 37 x 37 mm form factor, integrated OSD, 12-channel output and support for DJI/CADDX HD video.
Choose the CrossRace Pro for a higher-performance Flight Controller with parameter encryption and extra 12 V power control; where reprogramming and your own development matter most, the standard CrossRace may suit better.
Combines ArduPilot and Betaflight feel
PosHold mode helps stabilize the drone when you need extra control, manual mode suits active, precise flying, and the automatic return to the launch point reduces the risk of losing the drone on signal loss or in uncertain conditions.
High performance in a compact form factor
The STM32H743 processor, 480 MHz frequency and 1000 Hz scheduling frequency suit advanced projects needing fast response and stable operation, and despite the compact 37 x 37 mm size it offers many functions normally found in more advanced UAV and FPV builds.
Fast PosHold flying
Radiolink's high-dynamics algorithm allows active flying even in PosHold mode, with flight speed reaching up to 180 km/h depending on drone configuration, environment and other equipment.
Ready for DJI and CADDX HD video
The CrossRace Pro supports the DJI O3 and CADDX Walksnail Avatar HD Pro Kit via plug-and-play, and its connector interfaces and solder points let you expand the system without taking up more space in the build.
Support for 4-in-1 ESC and ESC telemetry
The CrossRace Pro has a 10-pin ESC connector with voltage monitoring, current monitoring and ESC telemetry, plus common protocols such as PWM, DShot and OneShot for flexible multirotor builds.
- Support for 4-in-1 ESC
- Support for ESC telemetry
- Support for PWM, DShot and OneShot
- Built-in 5 V and 12 V dual BEC
- 12 V BEC can be controlled via the transmitter for video transmission, for example
Integrated OSD for FPV flying
The integrated OSD module shows flight information directly in the video image with no external module needed – for example flight mode, distance, GPS signals, longitude and latitude, vertical speed, magnetic declination, current time, battery voltage, current, wind speed, return route, route, vibration status and heading.
Software-based vibration damping
Software-based vibration damping filters out high-frequency vibrations for more reliable sensor data, better altitude hold and stabler flight, and in many builds reduces the need for extra vibration-damping mounting frames.
Support for GPS, RTK and several mission planners
The CrossRace Pro supports GPS and RTK and can be set up via Radiolink Mission Planner, ArduPilot Mission Planner and QGroundControl; with the Radiolink GPS TS100 it adds dual interference-protection technology and high positioning accuracy.
GeoFence for controlled flight areas
The GeoFence function sets virtual boundaries for the flight, useful for training, long-range flying and missions where the drone should stay within a defined area; always check local drone regulations and flight zones before flying.
Automated quality testing
The CrossRace Pro is tested with an automated software-testing system covering functions from sensors to ports and interfaces, for more consistent quality than manual testing alone.
Suitable for many applications
- FPV drones
- Racing and freestyle builds
- Long-range flying
- Aerial photography
