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.

Whether you’re working on compact projects, running simulators, testing configurations, or need a dependable backup controller, the T8L delivers a smooth, streamlined experience. Its compact size and removable gimbal sticks make it easy to travel with, while the straightforward layout and reliable performance suit training, development, demonstrations, and everyday control tasks where consistency matters.

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.
