The RadioMaster Ranger 2.4GHz ELRS Module is a high-performance ExpressLRS module designed for reliable long-range connectivity and demanding RC applications. Its rugged CNC-machined aluminum housing provides excellent durability while also functioning as an efficient heat sink for improved thermal management.
An integrated OLED display, directional menu control, and two assignable shortcut buttons provide intuitive access to key settings, allowing you to quickly configure and personalize the module to your needs.
The Ranger includes both an omnidirectional T-antenna for everyday use and a Moxon directional antenna for improved link quality and stability when directional performance is preferred. Micro and Nano module adapters are included for broad radio compatibility, while the included cable supports CRSF-capable Futaba radios.
