Description
The brushless ECM offers all the same great features as the standard TRX-4M ECM 2.5, but with expanded compatibility. The integrated receiver and lighting control module maintain full functionality with existing Pro Scale light kits and work seamlessly with both TQ and TQi transmitters.
New Field-Oriented Control (FOC) programming allows the ESC to monitor motor position in real time, delivering ultra-precise control and smooth operation. It features two servo output ports and two Pro Scale lighting ports, while using the same battery connections and mounting points for true plug-and-play installation.
