KO Propo 80190 EX-1 UR T/R 2.4GHz SS transmitter, 4CH system for land-based R/C car models  [KO-80190]

EX-1 UR 4CH Transmitter Overview

The EX-1 UR is a 4-channel R/C transmitter built around a super high-speed CPU and the Ultra Response (UR) mode introduced for lower-latency control. The unit retains Advanced and Super-Normal modes and stores up to 30 model memories, making it suitable for hobbyists who switch between multiple scale car setups.

Physically the system incorporates a reduced-diameter steering wheel, a revised angle spacer, and a new trigger material to alter control feel and response. The radio is presented as a complete transmitter/receiver (T/R) 2.4GHz set and is specified for land-based R/C use, with monitoring functions for third and fourth channels.

Functionally the EX-1 UR focuses on configuration and tuning support rather than automated driving features. Steering and throttle are highly configurable: travel, trim, curve, speed modes, and monitoring are available for precise matching to servos, ESCs, and motor behavior in scale car applications. Timers and lap navigation aid track-side setup, while memory copy and restore tools help manage multiple model profiles.

The KO Propo EX-1 UR 4CH serves as a configurable transmitter platform with low-latency UR processing and multi-model memory, intended for hobbyist scale car setup and on-track tuning tasks.
