Traxxas 6254 ECM Brushless 3-Channel Speed Control for TRX-4M

The brushless ECM offers all the same great features as the standard TRX-4M ECM 2.5, but with even more compatibility. The integrated lighting control module and receiver maintain all existing functionality with existing Pro Scale® light kits and works with both TQ and TQi transmitters. New field-oriented control (FOC) programming allows the ESC to monitor the motor’s position for ultra-precise control. The brushless ECM offers two servo output ports and two Pro Scale lighting ports and even uses the same battery connections and mounting bosses for true plug-and-play capability.
