Tekin RX4 Brushless ESC with a rugged hardbox waterproof housing offers a versatile, weather-ready speed controller for 1/10-scale rock crawlers and other off-road RC vehicles. It supports both sensored and sensorless brushless motors and features Tekin’s D2 dual-drive mode for adaptable performance across different terrains and driving styles.

Designed to endure tough conditions, the RX4 includes a heat-dissipating heatsink and an auto-on temperature-sensing fan, solder posts for easy wiring, and high-density copper FET boards for efficient power delivery. It supports 2S to 4S LiPo configurations and a broad range of motor Kv values, and it can run both brushed and brushless setups. Programming is streamlined with One-Touch QuickTune, one-touch radio calibration, and HotWire compatibility for advanced tuning, plus an on-board temperature indicator and data logging for performance analysis. A high-voltage BEC powers servos for reliable steering in rocks, dirt, snow, and mud, making it well-suited for rugged off-road adventures.
