The Ecopower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo is an incredibly powerful sub micro option developed to provide a more rugged upgrade for the Traxxas TRX-4. Also, when paired with the Samix TRX-4M Brass Servo Mount (SAMTRX4M-4068 - Sold Separately), this makes a great upgrade for the Traxxas TRX-4M. But, this servo is a great upgrade for any sub micro servo application!

Delivering 64 oz-in of torque and .09 transit speed at 6.0V, the 640T will operate at a level that makes other sub micro servos feel inadequate in comparison. The servo features an all metal gear train for durability and waterproof circuitry that will stand up to the elements. So if you're tired of your small servos delivering small performance and want to try something with more muscle, step up to a 640T and shift performance into high gear.


SIZE NOTE: The 640T is not an exact physical copy of the 2065 and is a few millimeters taller, and may not work in all other applications where the 2065 is used. Please see the Compatibility tab for verified model compatibility.

TRX-4M NOTE: This servo is only compatible with the TRX-4M when using the optional Samix Brass Servo Mount (SAMTRX4M-4068 - Sold Separately).

I needed a replacement after my stock servo stop working. The 640T fits nicely and seems to be strong. My truck shifts smoothly and effortlessly now. I have only run it a few times, but I would recommend this servo to anyone needing a shifting servo.

I just installed two of them. The first impression is much better than stock TRX-4 microservos. Double torque and speed, seem more durable.

Bought one to use in my TRX-4. Its faster and stronger than the stock servo which died after about 2 weeks of light use. Since I bought it I've been out more driving my truck in the creek with this while its been raining and snowing and no problems at all. It doesnt get hot like the stock servo did. Great servo

Overall I would recommend these servos as great replacements for the stock TRX-4 diff and trans servos they are much stronger and do better with water.

I purchased three of these on March 7th 2020 and six months later one has began to fail while the other two are still working strong. Keep in mind I spend most of my time driving up streams and once in a while sinking it in deep sections... I'll be buying a replacement!

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo
I purchased this servo for a used Latrax that I got that didn't come with a servo. This does not fit without grinding out part of the chassis, but I made it fit and it works great. 5 stars because they don't claim that it would fit. I just took a gamble.

These actually work in the TRX4M. I went the DIY route…..I used wire cutters to snip off a little bit of the stock servo mount, as the servo is a little bit too big, and it’s held up really well and steers super fast. You have to modify one of the servo horns that came with it, as the Traxxas servo uses a micro servo with a full size output gear.
Definitely recommend!

Fits the TRX4 fine but it will not fit inside the trx4m servo mount. The servo is just a hair too long for the trx4m servo cage

I recently bought 3 of these servos one was DOA but with all electronics it can happen. I’m not going to complain about about the problem with the one that was DOA. The other two are extremely good. Amain will always be my first choice for all my parts!

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo
Well I got three of them and 2 worked great right out of the box but the third one did nothing when I plugged them in to test them first before I installed them so I got my pliers and moved the gear back and forth and plugged it in one more time and its working for now will see how long it lasts not to happy about it sticking but only time will tell if they are any good but they are better than the stock ones for now install was no problem take old out put new in nice snug fit

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo
first one was dead on arrival Amain replaced it without any fuss best customer service Ive experienced in the rc community. If you want a bad customer experience try horizon hobby junk. New servo works great opened up the bad one and there was wire strands bridged where the servo lead was soldered to the circuit board.

Purchased three of these Eco power sub micro servos for my Summit build as they have been great in the past for my Trx-4's and other rc's. Have one that's at least three years old and still going strong.

Seems a little expensive for what it is, but I have had this installed for more than two years, and it's still working fine. It's slightly stronger and faster than the original TRX-4 diff-lock servo too.

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo
Purchased this servo under the recommendation of YouTube rc reviewers. Performance was great the first time I ran the truck. Then after cleaning it lightly with clean water and NO compressed air the servo died due to water damage. Just keep buying the traxxas servos OR buy Savox. They may be power hungry but Savox at least can produce a truly waterproof servo. Hope this helps someone. Cheers.

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo
I've had great luck with these servos as a drop in replacement for the Traxxas 2065 units on the diff lock / shift trains. Having the metal gears is great, plus the torque and speed are just over double that of the stock unit. Granted, they are not the highest end servos that you can buy, but double the performance for the same price as stock? I recommend that you combine these with Hot Racing TRXF24P06 aluminum control servo links to get full metal to metal all the way to the control link. Happy trails!

This is a very powerful servo over the factory Traxxas micro servo but only time will tell if it is durable I modded my latrax prerunner to fit this servo but it is not a direct bolt on
