The EcoPower WP120T Coreless Waterproof "High Torque" Metal Gear Digital Servo is a great choice if you are looking for an affordable, waterproof, high voltage upgrade. The WP120T makes 337 oz-in of torque and .11 transit speed at 6.0V. But when you crank the voltage up to 7.4V, the WP120T delivers 400 oz-in and .09 speed, making it an excellent option for scale crawlers, 1/10-1/8 monster trucks, 1/10 2WD and 4WD buggies, as well as 1/8 scale buggies and trucks. Plus, its a great option for boats, and other surface applications that can benefit from a high torque, high voltage, waterproof servo. The WP120T is waterproof up to 1-meter so driving in the rain, puddles, snow and mud are not an issue. Metal gears were used to create a durable gear train that can be serviced if needed, and the plastic case with aluminum center section keeps the servo running cool while remaining lightweight. Plus, the digital circuitry allows compatibility with vehicles that use traction control/gyro systems, making the WP120T a viable option for models that are equipped with a stability system.
