RadioMaster T8L Radio Controller (ELRS)

The RadioMaster T8L packs dependable ExpressLRS 2.4 GHz performance into a clean, ultra-portable transmitter with no screen to get in the way, making it the first screenless radio officially supported by ExpressLRS.

Ideal for compact projects, sim time, test benches, training, demos, or as a rock-solid backup you can throw in any bag.

With high-precision quad-bearing Hall-effect gimbals, integrated USB-C charging, and simulator compatibility, the T8L is ready to go right out of the box. Setup is quick and easy through a web-based configuration tool that runs directly in Chrome or Edge.
