Servo Overview:

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 Waterproof High Torque Metal Gear Servo
I installed this into my 1.9 rig, took it through some vigorous terrain, alot of rock climbing and mud and this servo performed flawlessly, i ran it on the 7.4v setting so it had plenty of torque to get me through the run. I am very happy with it, I highly recommend it.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Man oh man, this servo hits all the right buttons. With transit speeds tuned at 6.0v or 7.4v its noticeable & quick! The coreless motor has great torque and the servo has a maximum dynamic torque of 400oz. Even with running the servo in warm environments it still keeps a decent temp and doesn't seem to get hot (important to this guy). Last but not least the price, at $69.99 you really do get a great servo for your dollar. Guess what... and its waterproof!

Get yours today.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
This servo did not make it through it's first outing, 20 minutes of light use and it stripped. The gear that stripped was the biggest aluminum gear not the plastic one.
I am going to replace the gears for 12 dollars because I don't have the cash right now to buy a better option. save your self the hassle and get a better servo. this was a big let down for me. It was a very smooth servo for the short time it was working.

After the rebuild my luck was not any better, I had the same problem it just lasted a little bit longer than the original. My end points are set correct and after going with a cheaper servo I have had no issues at all (Though the ECO was smoother and quieter)

I love Amain but not so much the servo experience. I don't like giving bad reviews I am just giving my honest opinion.

OK, I understand rebranding, but this is a JX CLS5830HV at over twice the price. Great servo, but not worth $70.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Put in my trx4. Never felt like it had a solid center from the beginning. Only ran it once and now it doesn’t feel like there’s a consistent center. At all . I was a eco power fan boy so I had high hopes but definitely wouldn’t recommend.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Ive heard people comparing this to JX CLS5830HV, but when running them side by side the Eco sounds like a well oiled machine in comparison & the power & speed is undeniable......

EcoPower WP120T Waterproof High Torque Metal Gear Servo
I had my doubts but I must say so far the thing is lightning fast and it swings my mp9 tki4 wheels like nothing I like this more than my 100 plus servo!!! I bought this servo cause of all the great reviews on here now the only other test is how long will it last!!! And and can't beat 13$ replacement gear

EcoPower WP120T Waterproof High Torque Metal Gear Servo
I installed this as a replacement for the Tactic TSX45 steering servo in my Axial RR10. It works well with the RTR electronics, has a one year warranty and a rebuild gear set is $13. Performance wise it handles the 2.2 wheels and tires pretty well. It steers pretty quickly, and the torque is pretty good. I think it's a great replacement for the RTR servo. I primarily use my RR10 to hit local trails in Southern California which is about 90% rocks and sand.

Ordered two of these eco power steering servos for my summit build. Certainly wasn't expecting the speed and torque that these produced. Great servo for a decent price!

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Bought this on 2/10, it was a recommended servo in an Amainhobbies article entitled "5 Best Upgrades for the Traxxas Maxx"

Got two weeks out of this on brand new Traxxas Widemaxx that is driven mostly on grass and fine gravel and no bashing. Started out ok, better than stock but started getting slower and today the gears must have stripped in addition to a plastic tab for mounting snapped off. Put out a little more money, this one is not recommended by me.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
I have 3 of these now in three different crawlers and they all perform great. I don't bash my trucks, just scale trailing and crawling. Good servo for the price and will buy more in the future when needed.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
First time out with my TRX4 as 3 minutes of mild crawling around, the servo stripped out. I know A main is good but shipping etc if covered by warranty is just exhausting. $70 down the drain and I will find a different servo.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
They, or someone, need to have an upgraded metal gear to replace that center plastic gear. Made it about 5 packs in an 1/8 truggy and was stripped. Otherwise, its a fast and powerful servo

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Drove it for 15 minutes on some slick rock and then I hit a bump at about 5 miles an hour and stripped the server horn and replace the servo horn And then the servo had play in it like a year-old server so would not recommend buying would give a zero star if I could thank you

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Edit: as of about about mid 2023, she’s borked. Served me well in my erevo, but after 3 years the transit speed is super unbalanced. Really disappointed I bought new gears for it just to find out it was broken. I did notice that she runs quite hot even on 6v, and my new preferred brand of servo runs much cooler.
Popped one in my erevo 2.0 and I’ve loved it. Plenty of speed and power, excellent value. Update: it’s been quite a long time and I still find this to be the best value in servos from a reputable brand. As long as your following standard procedure (servo saver with a reasonable amount of protection, no more than average 1/8 scale basher wheels (bead locks may not be good unless used in a low speed application) it’s the fastest tough high torque servo on the market.

EcoPower WP120T Waterproof High Torque Metal Gear Servo
Not great. After 2 packs it no longer can find center. Maybe good for low impact scale crawling but not for the rough stuff.
