The S614S is a standard-size digital servo designed for demanding surface RC applications. Its steel gear train provides strong and durable performance for steering and other control functions. The servo delivers up to 14.5kg-cm of torque at 6.0V and uses a 23-tooth output spline. Its water-resistant construction makes it suitable for models exposed to wet or muddy conditions. The servo features dual bearings, a brushed motor, and a universal connector for compatibility with supported RC systems. Spektrum lists it as a replacement component for several Losi models, including the 8IGHT, 8IGHT-T, and LMT monster trucks.
