Impressive range with SiK Telemetry Radio V3 433MHz 100 mW

This Holybro SiK 433MHz 100 mW telemetry radio is a small, lightweight and inexpensive open source radio module that typically allows a range of better than 300 meters “right out of the box” (range can be extended to several kilometers with a special antenna). This radio is compatible with all Pixhawk Standard and other plug-n-play flight controllers, providing the easiest way to set up a telemetry connection between the autopilot and the ground station. It uses open source software that is specifically designed to work well with the MAVLink protocol and integrate with Mission Planner, Ardupilot, QGroundControl and PX4 Autopilot. The radios can operate in either 915 MHz or 433 MHz mode, and you should buy the model appropriate for your country/region.
