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. 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.

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo (TRX-4)
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!

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 (TRX-4)
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.

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!

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!

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo (TRX-4)
I replaced all 3 stockers in my heavily modified TRX4 Defender after one of the stock diff servos failed after maybe 3 hours of running. These are still going strong after 2 years of use, although I never submerge my vehicles in water and seldom run them when things can get really wet or muddy, and if I do I immediately do a 100% tear down of the rig and clean amd service all the bearings, gear boxes, every single part gets removed and cleaned. In 35 years and close to 100 different vehicles, Ive only had maybe 3 servos fail and all of them were stock traxxas models that failed nearly immediately. Thats why I only buy RYR's when I have to to get the vehicle I want. The first thing any new RYR vehicle gets before ever being run is all new electronics, moter esc steering servo etc, and a Futaba reciever for my 7PX and 7PXR. I left the stock 3 micro servos in the TRX4 because these were not available when I purchased the truck originally. The people who complain about $15.00 servos not being 100% waterproof need to realize that no cheap electronics work well combined with water, snow, mud etc. These are super cheap so grab a couple extra if you drive your rigs in those environments.

Works great as an upgraded dig and speed servo on SCX10 III. Does take a little finagling but not hard to fit overall.

EcoPower 640T 13g Waterproof Metal Gear Digital Sub Micro Servo (TRX-4)
Got these excited ... Thought it was all good and a easy replacement. Only worked a few weeks and both died yesterday indoors dry. Cant be i just got them. Tested all my electronics and all good ??? They ARE NOT waterproof! One had the screws loose (i guess i shoula checked first) but both are dirty an jammed i cleaned and rebuilt the gears are fine but they have no power.. Worked great fit great but only for a few weeks (outside a couple hrs each week). Anyone that knows or sees pics of my rigs know im very clean and maintain them/check everytime i go out. Huge dissatisfaction and expect waterproof when said so..
