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 monster trucks, 1/10 2WD and 4WD buggies. 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. Want more? We back this servo up with a 1 year warranty - so drive with confidence knowing that EcoPower has your back, with a tough, powerful servo upgrade that wont break the bank - and wont slow you down when mother nature tries to change your plans.

EcoPower WP120T Coreless Waterproof High Torque Metal Gear Digital Servo
These are sort of hit and miss. I have only had 2. One is in a TRX4 gr8 aver a year and I have had zero issues with. I just recently bought another for a Pro MT 4x4 and after 5 minutes it stopped working. I was only driving on pavement and hadn't flipped or anything. I think there is something wrong with the gears inside as the motor still moves when I tried to turn. I am not sure if the warranty will apply for this but if it does not I won't be buying anymore.

I got this as an upgrade for my Talion and it is great but I had to replace one of the gears after a minor tumble. The good thing is that you can buy replacement gears.
