RadioMaster T8L RC Transmitter ELRS (FCC) – Choose Color

The RadioMaster T8L brings the power of ExpressLRS 2.4GHz into a clean, compact form — and is the first screenless radio controller officially supported by ExpressLRS.

Designed for pilots who value simplicity, portability, and reliability, the T8L delivers responsive control with up to 10 channels via the CRSF protocol. Whether you’re flying a micro multi-copter, fixed-wing aircraft, or just need a dependable backup radio, the T8L provides a smooth, streamlined experience — perfect for indoor or park flying.

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 — no display or external software required.
