RS Gen 3 SPEC Sensored Brushless ESC for 1/10 RC Vehicles (TEKTT1157)

RS Gen3 SPEC electronic speed controller for 1/10-scale RC cars is a high-performance ESC designed for SPEC-class racing. It supports sensored and sensorless brushless motors and is compatible with 13.5-turn and higher 540-size motors, delivering precise, predictable power. True ROAR SPEC mode keeps timing and boost features off for fair competition, while QuickTune One Touch programming, a HotWire port, data logging, sensor checker, an on-board temperature indicator, and ESC self-diagnostics provide easy setup and monitoring. The unit also features a durable HD Solder Post Design for robust connections and HDAC high-density copper PCBs for efficient power delivery.

Designed for 1/10-scale cars and trucks, this ESC combines a lightweight chassis with smooth throttle and braking response. It offers adjustable torque control, throttle and brake frequencies, and a 3rd-channel input for on-the-fly drag brake adjustments. The LiPo-safe BEC supports programmable voltage cutoffs and a sensor plug enables precise motor commutation, giving racers reliable performance with either sensored or sensorless powertrains and the flexibility to optimize setup for practice and race day.
