Excellent explanatory video for reference and smart tips on how to keep everything in order. I love all of my EcoPower servos. Great job Brett. Thanks. And I am glad that you are feeling better, i.e. table bongos.

Thank you!

[@dennis3004psp]

i have a TRX6 and a 5 channel spektrum and a castle esc, so i search a reverse shift servo. then i can add the aux wire for the dragbrake to this channel. i want the brake only in low gear not in high.

I'm looking into getting this as replacement for my trx4m steering servo. Do I still need to buy the mount?

[@AMain_Hobbies]

Yeah, you'll need this mount (or one like it): www.amainhobbies.com/samix-trx4m-brass-servo-mount-black-11g-traxxas-ecopower-samtrx4m-4068/p1470047

What is happing with TRX4 SPORT KIT??? Never comes IN STOCK at Amain web store....

[@AMain_Hobbies]

I know! We're waiting on one too. Hopefully Traxxas will have more soon.

[@rva1945]

Do those servos come with the unassembled kit?

[@AMain_Hobbies]

No, the servos are not included with any of the TRX4 trucks; they are sold separately here: www.amainhobbies.com/ecopower-640t-13g-waterproof-metal-gear-digital-sub-micro-servo-trx4-ecp-640t/p859667

Just hooked up 3 new eco powers in my trx-4 and none of them work. Re-installed traxxas micro servos and they work; two of them are broken but they are trying to work. Not even a twitch out of the eco powers. Jake T at Amain said it’s a common issue and can be fixed by a screw..? He told me to call the 800 number, but I would like to avoid that if I can. Please help, Thanks.

[@AMain_Hobbies]

Hey Zack. I was told some servos were packaged with the incorrect screws. We have updated screws we can send you; they feature a smaller head on the screw. The screw with the large head puts pressure on the case which causes issues. This is why Jake asked for you to call. Hope this helps Zack and sorry that the servos came with the incorrect screws. We would like to correct this for you. Thanks.

[@maciekm.4169]

no endpoints adjusting?

[@elicopter_go_brr]

are they durable ebough so that you wont have to do it again?

[@AMain_Hobbies]

No servo can make that guarantee. All things wear out.

[@GastonMaqueda]

Sorry bro, but so disapointed with this servos. Terrible quality
I bought 4 of them.
The first one stop to work when i was testing the model after the "upgrade". 10 seconds.
I contact the seller. He refund me the money but not the shipping cost. A say... well is ok, maybe bad luck. No my fault, not seller fault and I purchase a new one.
I installed it yesterday and went outside today with my TRX4. 10 minutes of drive and again, the servo stop to works
The other 2 still working but I don't know for how long.
So dissapointed with this product. Thanks for the refund but i can't continue spending money in shipping . I will contact the seller again today for a refund and go back to the traxxas..

[@The_ThreeWheeler_Dude]

It’s a disappointment. I bought four. Tonight after 2months the fourth servo gave out.
