Overview of the EX-1 UR 4CH Radio

The EX-1 UR combines a fast-response CPU with Ultra Response (UR) mode to reduce control lag for precise handling in scale car applications. It retains Advanced and Super-Normal operating modes and offers storage for 30 distinct model configurations for racers who swap setups frequently.

Design updates include a reduced-diameter steering wheel, a modified angle spacer, and a new trigger material to refine control feel. Supplied as a complete T/R 2.4GHz package, the system is oriented toward land-based R/C car use and supports monitoring of the third and fourth channels.

Rather than providing automated driving aids, the EX-1 UR focuses on deep configuration and tuning. The unit exposes travel, trim, curves, and speed mode adjustments, together with monitoring tools to match servos and ESCs. Track helpers like timers and lap navigation simplify setup, while memory management tools assist with multiple vehicle profiles.
