The go to SERVO thread!
 

Just thought it would be a good idea to try and eliminate the countless number of servo threads by creating a servo directory.

This is what I'm going for. Please post the servo name, model and experiences that include application(In what vehicle), how long you have been running it for, what problems if any, and some comments on the performance... I will update the info to this post at least one time a week. And want to try and get this on the sticky list!

Any feedback is welcome! I'm all in for great ideas, or changes to the layouts. I will add some info to get it started. Now lets get posting! :nod:

When I talked to Spektrum, their rep said they are not related to Savox.

I used this servo in my ve8 e buggy and It broke a gear very quickly running on a hard surface. No crazy crashes that I haven't done with any other servo, but the main gear (the one that is also has the output splines) broke several teeth off. I don't use this servo for 1/8 steering any longer.

List updated.
Spunky: can I get a rundown of your Hitec please :D

Murray: At RCX I talked to the Savox rep about Orion re-badging, he said that Savox sells the servo to Spektrum as well as a few others. I have heard this a lot on rctech as well. If I am wrong (I am a lot lol so don't take this as an insult but just a discussion) please get me a source. I want this list to be as accurate as possible. THANKS YEAL!;)

savox1256.

Runs AWESOME in 1/8 buggies and trucks. I would say about 1/2 of the people at the my track run this for steering and have never seen one fail. Ran in a VE8 for about 5 months. A+ servo

I had also read about Spektrum being a rebadged Savox and that is why I asked Spektrum when I called them. I do not have the name of the rep I talked to but called the number on the Spektrum website. Definitely no insult taken........I am new but have been researching servos for the last several days. Thanks for setting up this thread. Wished it was completed several days ago.

Thanks RC8!

Murray: I'll probably wind up calling both companies and get definite answers. Two diff answers from service reps on the same subject lol. Just funny how the specs line up identical and they are similar looking. We shall see! Once again not trying to insult. :nod:

i have some 2158TG's coming for my jammins, i will update when i've had them a while and can give feedback!

Updated. Thank you EPiC! Can't wait to hear the info on your 1258tg!

this thread is a great idea. a suggestion i have would be to either include retail pricing and/or links to the servos on amain. that way if someone needs info about servos they can come to this thread and see it all laid out for them rather than having to search through all of them online.

i won't have my servos for a couple weeks and who knows when i will have everything to actually run my SCRT10 cuz i'm building it from scratch, but once i do i will definitely update about it.

JR Z9100T

worked great in my RC8B, and my VE8. DOES NOT WORK WELL IN LOSI 8 Family! Comes with a 3 year warranty!

Just installed and ran my new Spektrum 6040. Running a stock sc10 esc and no issues. Super improvement over stock servo. Never thought a high speed servo could make that much of a difference.

Why don't you take all this info and put it in a spreadsheet so its searchable?

Just a thought - if you do, you should include spline count for the servo as well - see a lot of ques about what fits what servo.....

List is up to date!

Thanks for all the reviews!!!! STICKY STICKY STICKY! :D

Murray: Amazing the difference in response time right? When I was younger I couldn't run fast servos. Now I can't run slow servos! Anything over .09 for me is slow now :o .

Good idea about the spreadsheet too, I will take that into consideration when a large enough list is established. For now i think the scroll through list is easy enough for the basic user.

This servo came highly recommended by our LHS as the particular Savox servo was out of stock. So I bought 2 of them to try at RM120.00 each

After installing into my Agama Evo A8, the servo was Flawless with no glitching. However after 15 minutes of normal usage, the throttle servo toasted. (Just driving on tarmac surface with Correct EPA settings)

Contacted the MKS representative in Taiwan thru Facebook and he mentioned that the cause of the servo FET burnt was due to an Over-Voltage supply from my 6.0V NiMH 1500mah Receiver pack batteries...

What do you think guys??? :weird::weird::weird:

Anyway the other steering servo only lasted another 2 more months before it completely KO-ed also.

TBO, I was rather dissappointed with the way MKS handle my case and I hate to say this... There isn't any Warranty provided except for a Trade In Program.

Thanks for the add! I'll be updating the list this coming friday. So lets get some more on here! Thanks guys :nod:

never ever buy that kind of servo again... get a hitec or a savox...:nod:

True story!

Lets get some more on here to add to the list :nod:

I'll be at ROAR fuel nationals till Sunday so updates may not happen to often until then! Thanks!

What is the warrenty on a ko propo Rex servo.

Hey all,

I have a faulty steering servo. traxxas 2055 6.0V 6.2kg/cm

It doesn't work when I first turn on the TX/RX but after 5 - 15min it comes to life and works normally until I turn it off again. This jump to life seems to happen by itself, without any jiggling or TX input so I'm wondering if servos have an internal electronic breaker or cut-out for overheating or something?

My diagnostic testing shows it's a servo fault not the receiver or transmitter.

Thanks

Hitec HS-7955TG

I have used this for steering in my Losi 8ight-T 2.0 that I converted to electric and ran all of last year. It was my first year in R/C so it got quite the rough treatment driving full speed into the wall at the end of the straight and so on.
This year I sold the truggy to a new guy and it is still being given the rough newbie treatment.
No problems of any kind.

Edit: Weight (grams): 65.0

Fitec FS5679M,bought 4 samples which is inexpensive,After building one of it in test car and race it Last race.
feel its functions very good ,it is fast ,strong and centering is perfect .
none of them is chattering round zero like other bad servos
very satisfied and would like to share with you.
this a nice alternative for our racers,I think.
It is worth to try!

Like someone else said previously in this thread, there is already a database/website which lists pretty much every servo in the market, with all the specs and approx street $. Its what I used in making my choice in servos (in my case, XQ-POWER titanium-geared servos which I cant speak of highly enough)

http://www.servodatabase.com/

Alot of people are going to have different opinions on the same servo....some people have success with certain servos whilst others have had issues......this thread will just get too messy to find any information easily enough.

My 2c.

For those on a budget and want something better then the basic plastic gear servos, the Blue Bird range is a great Option.

In my back up 1/10th touring car I'm using a Blue Bird BMS-631MG Super Fast Servo (Metal Gear).
Stats are.
Weight: 46 grams / 1.62 oz.
Dimensions: 40.5 x 20 x 41.2 mm / 1.60 x 0.78 x 1.54 inch
Torque At 4.8V: 5.0kg-cm , 69 oz-in
Torque At 6.0V: 6.2kg-cm , 89 oz-in
Speed At 4.8V: 0.10 sec / 60° at no load
Speed At 6.0V: 0.08 sec / 60° at no load

Compared to my Savox 1251MG low profile servo, the performance is not that much different. It's a little bigger, heavier and not as much torque but for $15, it's a heck of a lot better then the plastic servos that come in the cheaper radio kits.

I should probably update this!

Servo issues cont.
 

I've found a semi-solution to my faulty steering servo.

It seems if I turn the steering trim all the way one way (say left) plus steer with the steering knob all the way to the left and hold, the steering comes to life after a couple of seconds.

If I turn the receiver off then on again the problem returns and if I do the steering trick it comes back to life but even faster. A third time and it happens almost instantly.

Anyway, not sure if this is a common prob or if my servo is just special.

servo failure
 

i just had a ace xp1313 servo fail on me last night. i installed a new m11x recevier in my sc10 last night. all was well right after i did the bind process. steering was working great. but after i started adjusting the end points. i noticed the servo started acting wierd. would run very slow in some directions and sometimes not respond at all. i dont think the radio or settings are causing it. i did try another servo and it worked fine. im new to electric cars with lipos. since the lipo is at 8.4 volts fully charged. does the servo see 8.4 volts? if so do i need a high voltage servo or a voltage regulator?

No, in most cases the servo gets somewhere between 5V-6V from the ESC.

CANT FORGET THE FUTABA BLS LINE FELLAS!!

Hey guys I hope a question is ok in here.

I burnt up the servo in my losi 8ight 3.0 RTR and am having a real hard time finding a replacement servo to fit. I have bought the savox 0231 and 0230 and both don't fit right. The mounting holes don't line up and the top of the servo where the horn connects sits to high. The steering linkage is all in level and wonky.

Any recommendations on what servo fits right and has the right height?? I have contacted my LHS, horizon, and savox and no one has an answer. PLEASE HELP!!!
