EX-1 UR 4-Channel Transmitter Summary

The EX-1 UR pairs a high-speed CPU with Ultra Response (UR) mode to lower input latency for sharper control on land-based R/C car models. Advanced and Super-Normal modes remain available, and the radio can store up to 30 model setups for quick swaps between scale car configurations.

The hardware includes a reduced-diameter steering wheel, a revised angle spacer, and a new trigger material to change the tactile feel and response. Supplied as a complete transmitter/receiver (T/R) 2.4GHz system, it is intended for land-based R/C use and offers monitoring functions for the third and fourth channels.

On the setup side, the EX-1 UR emphasizes manual configuration and tuning rather than automated features. Steering and throttle adjustments cover travel, trim, curve, and speed modes, and monitoring helps match settings to servos, ESCs, and motor behavior. Timers and lap navigation assist with on-track adjustments, while memory copy and restore tools simplify multi-model management.
