The Ultimate RTR Steering Servo Upgrade

The EcoPower WP120T Rock Crawling Steering Servo is a great choice for anyone looking to upgrade their rig with something more capable. This steering servo works with popular RTR's like the Traxxas TRX4 and Axial SCX10 series. The WP120T makes 337 oz-in of torque and .11 transit speed at 6.0V. Being high voltage, you can crank the voltage up to 7.4V where the WP120T delivers 400 oz-in and .09 speed.

Plus It's Waterproof

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.

This servo is awesome!!! I bought it to replace my crappy Savox that I had for about a week before it stripped all of its gears. Anyways, I am running this servo at 7.4v with 2.2s on my TRX4 and it is FAST!!! Comes with like 5 different plastic servo horns which can be cut down to make on-the-go get you home spares, which I have done lol. I do wish this price it was all metal gears, but I have yet to have any problems with it after about 3 months. This servo is 10000% worth the $70, and this will be going in all my rigs when I acquire more.

These are becoming my go-to servo for all my crawlers. I’ve been running savox 1210’s and protek 370tbl’s and I still love them, but these are the best bang for your buck. Also a lot quieter than the 1210’s. I beat the heck out of mine and have broken front end parts on my trucks with them, and no issues yet. Love love love them! #rokkmachine
