Now that's how you stand behind your products!! Customer service and support, at it's very finest!

I have a 100S, 100T, 130S, and 130T currently.. All have been nothing short of exceptional and have also taken me straight to the podium, multiple times! Recently, I've noticed a slight amount of 'backlash' in the gear mesh on my 100T servo in my Pro2 SCT. With or without power, at neutral, you can wiggle the horn and primary gear about an 1/8", at the end/outside of the servo horn. No 'shakes' as of yet, and it still performs fine, it's just that I've noticed a slight left to right movement, while tearing down the straightaway.. And upon further inspection, the above is what I've come to as a preliminary conclusion.

Any ideas?

Thanks for the great products, guys.. And Marty, you're the man!! :D

I put one of the new servo's in my ebuggy recently.
It started shaking again with one day of practice time.
I contacted Amain again, they admit to the problem now.
They asked me to send the servo's in for replacement, again, but this time they are sending different servo's.
So far Amain has handled this well, I just hope they get this worked out as these servo's are great.
Will report back when I have more info....

What do you mean by that? Sending different servos?


Cheers

If I remember the numbers correct, they are replacing the 150s with the 250t as the specs are very close.
According to the tech, one of there own is running that servo in his 1/8th scale with no issues.

All servos will develop a bit of play in the gear sets as they break in a bit. But if you feel it is an unusual amount or if it is negatively affecting performance please let us know so we can get it fixed or replaced for you.

I assure all of our customers that we are working extremely hard on our servo line. We have had some issues with some servos and they are being addressed. We will not rest until we provide our customers with the best servo money can buy at affordable prices. Our servos are already pumping out insane numbers, now we just need to weed out the few that have had problems and make it up to our customers.

I will replace my servos with these as needed. I respect the support and customer service of amain! I talked to a rep a few months ago and he assured me that their servos would be top notch. I went a different route for the one I needed to replace for lack of input from the "field". Now, I see that amain is doing everything possible to make these a great experience for the consumer. Look forward to getting my first one, although, it might be a while as savox are pretty good also.....

Would the 150T be a good choice to run from the BEC of a Viper VTX8 in an Ebuggy?

130T servo shudder
 

I have what I think is a similar issue with the servo appearing to have trouble finding center.

However, this is only with NO LOAD.

When I have the chassis supported with no load, the servo shudders pretty badly. As soon as I let the front wheels simply touch the surface it stops immediately, and appears to be just fine. So far, while driving normally, it also appears to function properly.

Is this more than a cosmetic issue? I would think the shuddering could prematurely wear the servo, but looking to get others thoughts. Nice servo other than that. To be clear, as soon as I apply load to the servo and turn left or right, it seems just fine at getting back to center. The shakes under no load is pretty bad though, more than just a bit.

If it truly doesn't effect the life or performance of the servo, I can look the other way until I set the car on the track.

What model do you have?

130T

The reason is interference. When you set your car to ground. It goes away. I had the same issue. Once I change receiver. Problem dissappear. You might want to look at your receiver placement or anything which might cause interference.

Shaking could most definitely be caused by radio interference. Usually caused by nitro engine vibration but it can also happen in electric vehicles if the receiver has taken some hard hits.

Swapped out the receiver and transmitter, This is not a case of radio interference.

In my experience, the "shutters" are caused from a Blown brass Bushing in the top case or a Blown Gear train.

Protek Shakes 150t
 

Hey! I recently got two new Protek HV servos 150s and 150t about a month ago and the 150t has started shaking really bad and even while turning with no load. I had a set of Savox 6.0v 1256/1258 for 2 years and no issues at all just wanted to start using lipo receiver packs so I got these Proteks. Anyway I sent a email to Amain about the shakes and they want me to send it in but I have no HV backup servos and a bunch of important races coming up. I wonder since I have spent thousands in the last two years and NEVER once complained or ask for a replacement even when something gave me a problem if they would send me a replacement servo first then I send this one in. How long does it usually take to get a servo back after RMA from Amain? This sucks right in the middle of racing series here in my local area! Mine shakes bad even off jumps and while pitting also seems to have a spot where it sticks when turning by hand slowly when power is off.

Phone em up and tell them to temporarily your CC with the price of a new servo and Refund the $$ when they receive your Busted servo.

Tekin among other companies have been known to do this when they have a customer in a bind. :nod:

A-main should do this for Any customer in your situation.

Waiting for RMA stuff especially when/If your in a different country can be a little tiring.

Well I tried to get them to send me a servo before they look at this one and they would have done but not in stock so I have a back order. The returns tech I spoke with was pretty decent about it but I still feel since my first order 2011 and $4,000+ I have never once had a RMA or complaint nada they could sent me something similar. I got lucky and got a new Savox 1268 HV servo for $75.00 because I didn't want to put one my 6v servo back in and change back to Life pack. Anyway I am considering buying a 1267 HV Savox and just stick with what worked for me for 2yrs. Savox but the Proteks look great and performance stats are awesome but I am very OCD about my gear I travel and spend good money to race so that's not how I want to lose. I also understand that new products are always subject to issues and not saying they wont fix them either so hopefully it will work itself out SOON.

The 10 year old JR in my sedan does that. I'll show ya on Thursday. It happens when the natural frequency of the steering system matches (or is close) to the feedback rate of the servo. Can also be an overly aggressive feedback algorithm causing "overshoot".

I generally touch the tires to stop it if it happens. You can also use thicker grease in the gears to help damp it out.

I have the vibration on me mbx6e and eb48 with the 150s. I always assumed it was due to the servo saver. The speed and torque causes the spring to twist past center and bounce back. Each time the servo recenters and it springs past center in the other direction. Tightening the saver should clear it up. Maybe not the cause in all situations but worth checking if it bothers you.

I am interested in giving your 100S line a try. Currently I run the JR 9100S servo, it is significantly faster but trying servos in the .15 sec range, they still work as I would like speed wise.

My question is this, Has there been any consideration on increasing the warranty period to match the current industry leaders of 3 years?

Curious, if you remove any linkage to the servo, other than say leaving the horn on to view the issue twitching issue easier, does it occur ?

I can check that tonight if i have time to fiddle with it at the track.

cool.

Right now, another one is the 130T that has my attention as well.

My 130S also developed the shakes at the track today. Removing the wheels is enough to remove the shakes for me, no need to remove the whole linkage...

Servo still works great running on track but its a little unnerving to see the wheels shake back and forth while your car waits for a marshal or while its sitting on your work stand as you try to put on your body.

i am thinking a bout buying this one:
http://www.amainhobbies.com/product_...tal-Gear-Servo

it has a really nice specs, and a nice price, but the shaking thing is kinda worrying me.

I`m running the 100s in my e/buggy. I only have 1 day on it but so far so good.........

If its anything like I was told that could be the cause of the shakes on JR Servos, possibly a new top case would fix.

These servos have been on back order for months so hopefully they're sorting out the problems

From same company that makes Highest RC and who are making the Xceed PRO servos (when compared to a Highest RC servo I have personally) by the looks of it, in fact almost sure of it....

Sorry, but the 150 servo I bought to try a while back has killed itself as a steering servo in 1/8 buggy, same chatter as others have reported initially, and has somehow seized up/refused working all together. Its now a paperweight.

Not trying to hang anything on protek (a-main), they do offer nice goods, but they really need to look into this issue. Just voicing my personal experience with the one servo I bought.

Marty.....what is the MINIMUM torque rating you would suggest for an 1/8th e-scale buggy? 250??? Also looking for somewhere around .10-.12 transit time. With that being said, which Protek servo would you recommend? Thanks.

Figured since Amain has a special I ordered the 350T and 330T to try out in a MBX6TR, time will tell how they hold up.

I have been running the 230T for a month now with no issues. This is by far the best servo I have used in my opinion however I have never spent more than 150 on a servo so I guess I could be missing something.

For the price this one blows everything else away! It is super quiet and extremely fast. The toque is insane.

I have not bashed it much so no true torture test to speak of... YET.

I wonder if it is just the 100 series that is giving problems. Unless I missed something I have not seen anyone having problems with the 200 and 300 series. Anyone else using the larger servos?

I got some time in on my 330T and 350T now and am very pleased. Torque, speed and centering was all there. These ran super quite, more quite then when I ran the 7955 hitecs. I went to Savox after hitecs for there HV servos proved more useful.

Ill give these Proteks a bit more time before its final, but general conclusion is I found my new servo brand.

Every servo company has problems at some point it's how they deal with the problems and their customers as to how a company should be based on. If the company admits to the problem and continues to try and fix it and either fixes the product or replaces with an updated version or a better version that doesn't present the same problems that to me is a company to go with and stay with. I've run a Hitec 5955 for a long time now and no problems but have had several other Hitec servos blow. I've also had Turnigy servos in my D8 since 2010 with no problems at all and I crash a lot(not something I'm real proud of but true)

The 150T is the go-to servo for 1/8th applications. It has all the torque you could want with the speed to back it up.

My 130 started shaking one day. Then 2 weekends ago I took it to a race and after 2 qualifying heats the shakes went away and have not come back. it was weird.

anyone else have this experience?

I was just about to order several Protek 150T servos when i came across this thread. Has amain taken care of the problem(s) with these servos? If not, what other servo(s) do you guys and gals recommend? FYI: I have run HiTec (every single one of them failed within 2 months), Savox (had brown out issues from time to time w/ one failure), Futuba (got the shakes, stripped gears, and one just stopped working), and now I am running JR (Z9000T for steering and Z9000S for throttle). I have been running my JR servos for more than 7 years w/o a single problem. The only reason I'm getting rid of them is because I want to run lipo. Any help will be greatly appreciated.

Thanks

I was interested in the 150 range while the Radiopost Red model was unavailable. Turns out these were too. The Radiopost came back in stock so I bought them since. They have been real good for steering in a 1/8 buggy.

I highly suggest you try Hitec again, Ive personally ran Hitec for about as long as you JR. So imo you must have gotten a few lemons back in the day, or something funny's going on. Did you ever warranty either Savox or Hitec when you had issues ?

A few lemons... More like, two dozen lemons. I tried everything from cheap 311's all the way up to the best HiTec offered at the time. I sent several back to HiTec under warranty and those failed as well. I ended up giving all my HiTec servos away. As for Savox, I didn't send them back. I ended up throwing them in the trash. The way things are going... I am thinking about picking up some KO Propo servos and calling it a day. ;)

We sell a rather large number of ProTek servos with very, very low return levels. Yes, all servos can and eventually do fail. It's just the nature of the beast. The new cars are faster than ever before and the tracks we race on have harder surfaces than we raced on just a few years ago. Plus most cars either have no servo saver or they are run locked.

When servos got to a level where they had more than enough speed and power we more or less forgot that they were still made with gears and motors. Trust me I know because I am guilty of cranking or eliminating all my servo savers myself. Servos need to be looked at as a semi consumable item much like plastic parts. They shouldn't break unless you do something horrible, but they will wear out eventually.

As most of you already know AMainHobbies has a customer service department that is always there for our customers. We also have industry leading warranties on ProTek products and we go to great lengths to provide our customers with a positive experience each and every time along with the peace of mind that our warranties provide.
