Radiolink CrossFlight Controller V1.1 – Full Specifications, Features & Comparison

The Radiolink CrossFlight Controller V1.1 is a high-performance, next-generation flight controller designed for professional and hobbyist drones, RC airplanes, helicopters, rovers, and boats. As an upgrade over the earlier V1.0 version, this model introduces enhanced flight algorithms, sensor fusion, and broader compatibility, making it one of the most versatile controllers in the market.

✅ What’s New in Version 1.1?

Radiolink CrossFlight V1.1 includes major improvements in:

• Firmware stability

• Flight performance

• Sensor accuracy

• Hardware capabilities

It supports RTK, Neopixel LEDs, gripper functionality, and delivers more reliable multirotor and fixed-wing control compared to the older V1.0 version.

Difference Between Version 1 and Version 1.1

The SE100 is a popular GPS module made by RadioLink. The module comes plug and plays with a cable to connect with the Pixhawk & APM flight controllers. It can also be used with most open-source flight controllers, such as the PX4 and iNav FCs.

Unlike some of the cheaper GPS modules on the market, this one uses genuine components. It utilizes a U-Blox M8N GPS receiver and QMC5883L digital compass, so you can be assured of reliable performance. When testing, we found it acquired up to 20 satellites outside in under a minute, and even managed to get a 12 satellite GPS lock indoors. Another nice feature is the flashing green status LEDs on top of the module, which make it very clear when a position lock has been established.

Features:

High Positioning Accuracy: about of 50 centimeters positioning, and can be search 20 satellites within few seconds at open ground..
Excellent Performance: 2.5dbl ceramic antenna design have enhances the ability to get an extremely weak signal even though interference by ideal filter..
Top Configuration: with u-blox UBX-M8030(M8), 72-channel, MMIC BGA715L7 from Infineon, that’s better than single GNSS 7N..
Built-in electronic compass QMC5883L (I2C port) with high precision, which same technology as Honeywell HMC5983. Support multiple positioning systems GPS, GLONASS L10F, QZSS L1 C/A, BeiDou B1, dual mode operation..
Compatible with Radiolink Pixhawk Flight Controller, 1.89*1.6*0.59in, suitable for DIY drone, quadcopter, multi-copter, rc vehicle’s, etc

Specifications:

Velocity Precision: 0.1m/s
Max Height: 50000m
Max Acceleration: 4G
Sensitivity Tracking&Nav: -167dBm; Reacquisition: -163dBm
Sensitivity Cold Start: -151dBm; Hot start: -159dBm
