The servos steer my Punisher/Thunderbolt 2 with ease, I use them in pairs. 18 months and no issues except snapped plastic horns. Yes the spline is 23T and 7mm output. I've not found any horn that world fit correctly so ended up making a small number. I don't think many after market manufacturers will get involved as I'd imagine it's a small seller in the servo market. Large plastic horn is logo'd 'Spring', designed for RC Boats I believe.
Hugh  1 points - 3/4/2013
 
also, the output shaft is a 23T and is approximately 7mm diameter...
Hugh  1 points - 3/4/2013
 
I have done some research and this servo output shaft has the same specs as the Multiplex Jumbo Speed MC/V2. I can upload pictures but I just tested the Turnigy arm on my Multiplex and it fits perfectly. I hope this helps. Now the question is where you can find old Multiplex servo arms...
Hugh  1 points - 3/3/2013
 
I need the same answer for what Larry is asking. This should be a simple answer from Hobby King. They should at least know the specs of what they sell of their Turnigy products. Please assist ASAP!
LARRY  5 points - 2/14/2013
 
HOBBY KING PLEASE SETTLE THIS ONCE AND FOR ALL... What splined ALUMINIUM SERVO arm will fit this servo. i dont want hear say like 25 teeth, 23 teeth, just tell me what ALUMINIUM ARM wii fit, and no I do not want to use the plastic arms (yes I know they fit. Too many people say Futaba will work then in some reviews people say Futaba didnt work. So, only from HOBBY KING I would like a definite answer and hopefully your company has test fitted to GUARANTEE a firm and correct answer. THANK YOU, Larry
 Gary 2988 points
Sorry,cannot help,checked this servo and it is different to other Turnigy servo's in that it has a slightly larger diameter output shaft.Had a search for you but can find nothing that will fit this particular servo.
 LARRY 5 points
Thanks for checking guys. Too bad I spent twice the price on three different servo arms and 2nd day FEDEX shipping already. I will find a different servo for the 5B and sell this servo
 guitaramp68 40 points
maybe do some mods to get the desired app
 LARRY 5 points
So what mods would you recommend. I have been flying large scale rc planes (40% gassers) for 25 years along w/ racing cars, fast catermeran racing and fly Goblin 700/550 helicopters. I have extensive knowledge of the rc industry. I am aware and did purchase a servo adapter kit which yielded unsat results. so, guitaramp 68 what do recommend besides replacing servo which I have already done
LARRY  5 points - 2/14/2013
 
whick aluminium arm will fit on this servo and accept linkage hardware for an hpi baja 5b
 Gary 2988 points
Turnigy servo's usually have a 25T spline which is the same as Futaba,so anything stated for Futaba should fit.
 LARRY 5 points
So I receive my Futaba heavy duty splined servo arm today (Feb 19,2013)for this 33KG servo and it does not fit. So " anything stated for Futaba should fit" does not work. Give me a part number for an aluminum servo arm that you ( sell and I will purchase it. This is the second arm I have bought, lets make my third one the correct one ,Thanks guys

Servo Hallo have one quetion is this servo vor 7v oder 6volt? I´*ll will buy 2 for my Carbon fighter Thx vor helping
Joseph  3 points - 10/10/2012
 
will this be a good servo for a hpi baja 5b
 Gary 2988 points
Yes,should be good,plenty of torque,it has been designed with 1/5th cars/buggies in mind.
 Murat 2 points
whenever you are in my hand
 Chris 36 points
yes it wouks good it diddent line up persict but it truns it great
 satya 3 points
See look I have used this servo for robotics and dipole antenna movement. it gives decent torque but you have to be careful while mounting it. It never take more than 33 Kgcm i.e. 3.3 Nm. The motor electronics(i.e. MOSFET) get burnt while applying more torque...I have burnt 5 such...so be careful. You can use it for your application
 James 4 points
Put 2x in my 1/5th HPI MT dual servo steering. Had to mod mounts a bit but heaps of torque and no problems with the bashing around of the truck. I did run some silicone around the joins and screw holes and some grease on the gears. Best servos I could find.

will this servo fit a Tamiya High Lift without any mods?
 wellmanite 188 points
Do you know the size of servo required? The dimensions for this servo are* LxWxH 75mmX30mmX72mm

17mm mounting hole space
49mm from the bottom of the servo to the mount fins.
 MTA-4 87 points
No way it will fit. This servo is huge, and made for 1/5 scale cars and big planes.
 Juan 38 points
It would be difficult to install this servo, a servo is very large.
The Tamiya uses standard servos.

is it ok if i run this on a 2s lifepo4 battery pack rated at 6.6 v?? pls help!
 snake33 31 points
I would probably run a BEC to drop it down to 6v to be sure. You can get one on here for $4 or so?
 hnvasa 101 points
but i am using 8 such servos in one of my project...so whats the option for me?? using 8 bec would be too tedious...
 Khilra 129 points
2cell Lifepo are perfect for the job. any 6v RC aplication can handle 6,6v.
6v is a nominal rating, not a max voltage.

thnx...i recently tested yhis motors on a 2s life battery and they ran without troubles...
MegaNutball  2 points - 5/26/2012
 
How many volts can this take? Can it handle more than 6v?
 wellmanite 188 points
I use a 6v nimh battery and mine have a lot of torque. It could probably handle a 6.6v life battery.

 Albert 4 points
i use only 6v and very very life the servo
 traxxassweden 45 points
I use my servo on 6.6V and it works great!
 Sepehr 6 points
well I connected normal batteries to this, with voltmeter, it was at 6.4 volts and they functioned well and they still continue to do! but I would't go over 7!
hnvasa  101 points - 5/12/2012
 
hello i wanted to know the current (peak) of this servo...and which is the best source to power it for longer duration??
 hnvasa 101 points
is 6v 3A bec suitable to power this servo??
 snake33 31 points
Yes 6V 3A Bec would power this servo. Go for a 5A Bec if want to power more channels on the car like lights or a remote cut off switch. Amps wont kill the servo - excessive voltage will. Servo will take whatever amps it needs.

hey thanks for ur reply...my project actually includes 4 such servos...which bec to use in that case?? bec sharing would be a nice option??
caveryis  5 points - 5/3/2012
 
Hey guys. People have said that the spline is 23T, the same as Futaba. All the research I have done says that the standard Futaba spline is 25T. Do the giant scale futaba servos have a different spline count? I purchased the HPI Baja servo horn kit which has all of the standard sizes (Futaba included) and none of them fit. Does anyone know definitively of a replacemtn steering servo horn that fits?
 snake33 31 points
Hobbyking sell these two steering horns to suit (sorry cant post the whole link it gets www.link have used the original plastic/nylon steering servo arm fine - did you break yours?

This is one of the better servo on the market! 0.21Seconds fast and 33KG on around 6V for only 25$, it can´t be better!

Can this be used with Alloy servo arm for car 46mmxM3 (HiTec)...Product id - 026000003. ( The link is http : / / www . hobbyking.com/hobbyking/store/__20707__Alloy_servo_a
rm_for_car_46mmxM3_HiTec_.html Please
help
 Chris 36 points
i would say that servo arm would be a likke small this servo is massive and the stock arms would work fine and they are very strong plastic. hope this helps.
 Kyuubi 14 points
Actually the inner teeth of the plastic servo arms that were provided with the motor wore out. So i was thinking of using the metal servo arms provided by Futuba or Hitech. Please suggest which of them i can use ?? Are the servo arms of Futuba and Hitech are compatible with this motor ??

hi how much wight will this servo carry? i mean acualy lift of the ground as in wights?

also how smooth do they operate?

thank you
 Same As Above 17 points
Well it is rated at 33kg-cm. This means that it should lift 33 kg at 1cm out from center axis on the servo horn, of course as you go further out on the horn from the axis the lifting capacity will reduce. Servo operation is relatively smooth, centers well, a little jittery but not enough to be a problem in my HK 1/5th Baja 260s, bear in mind it is only $25, if you want want super smooth and precise in this size expect to pay more like $75-$100.

Can I directly cOnnect the servo to my reciever? 6v battery========>reciever========>servo. ????? Is this how it should be ?

It depend how many servo like this you connect to your receiver, if you will use on a car Rex there are no problem.
traxxassweden  45 points - 10/20/2011
 
I have buy one of this to my Traxxas e-revo. but this will not work on 5.5-6V. can I give 7.4V?? or I broke the servo with 7.4V?? what did you use? do you use a BEC? 5A BEC?? please help me!!
 __gena 14 points
I use BEC 6V
 traxxassweden 45 points
I haved orded one Castle Creations Bec and I hope it will work :)
 igloo_it 1 points
First of all it's more than enough for e-revo in any case if you will power up with 7,4volt you will destroy it.

what kind of servo arm will fit this servo hitec/futaba?
 Zahid Rasheed 70 points
Futaba
 ghackbar 1 points
A wide range of different arms are supplied with this servo. I bet you there is one that will fit your need, otherwise you can modify one to.
 caveryis 5 points
I tried a Futaba arm, and it doesn't fit.

Anybody using one of these Servos as a steering servo on a hpi Baja... Regards Sean
 Zahid Rasheed 70 points
Yap I do.. and it works without any problem. my 2 cents *)
 motas 6 points
I use this in mine. Ive run mine in sand and even half buried it has the power to turn the wheels and is plenty quick enough to control it.
Bobroham  6 points - 9/14/2011
 
What voltage can I run this servo on? Is there a battery you can suggest to run 2 of these servos and a receiver at the same time? Thanks
 Zahid Rasheed 70 points
within 6 volts would be safe
 motas 6 points
6 volts. Any 6v hump pack will do fine. Otherwise if your running electric it should be powered through the esc.

Hi. What spline count / size output does this use ? Where can one find servo horns/servo arms for this big servo ?
 Kurt Amour 1 points
i ordered one of these and they come with a fitting arm. i had to trim it down a little.
 jonathon 5 points
23 same as futaba
 aero007 48 points
23tooth spline count, 6.8mm diameter. But where can we find alum. servo arms/horns, is there other choices than a mentioned Integy part INTC23061GREY ? (they seem to also be found in red and orange) also is there a plastic replacement arm set that would fit ? With the strength of this servo, a plastic arm may be done for pretty quick

Will this Servo fit in a 1/10 touring car?
 Surfsmurf 50 points
No, I will say that the PRODUCT ID: HXT9866DMG is a much better servo for 1:10 both for touring car and drifting. If you drive Short Course trucks it is better to take a little slower and stronger servo instead.
 motas 6 points
No this is mostly for 1/5 scale cars. Have a look at MG958 it is a much better servo and will fit in a 1/10 car. It will be more than enough for a touring car.
yar6rider  2 points - 5/1/2011
 
I use this servo to steer my son's power wheel (kinda crazy me). I've believed the servo will do the job but the plastic servo arm came with it is my concern. Does anyone know where to find a metal servo arm that can fit this servo?

Does any one know how many splines the shaft has? Need an alloy servo arm
 Surfsmurf 50 points
It has 23 tooth and I checked with my other big servos if it was similar but it was not for:
HDS-9960MG not the same
Euroline Mammut not the same and it is a plastic spline.
 Surfsmurf 50 points
I have one Hitec HS-805BB with plastic shaft but it is not the right type either.

Hi, as someone knows what max. angle this servo make? I want to use in a rc sailboat. For me the best will be 180 degrees :-). Thanks in advance.

You can trim off the stoppers inside the servo to make it turn to whatever angle you wish. Its a trick I found while researching how to make a rc winch.

Thanks motas and hemant for the infos. motas, it's seems that the link that you give me it's the real one that I need, but the images aren't visible. Any alternative? Thanks.
 JohnMcG 21 points
NO NO NO you cannot just trim off the internal stops. You need to extend the range of the feedback pot by including a resistor at each end. All of which will blow the guaruntee
jzaero  1 points - 3/19/2011
 
can someone pls tell me about how much amps this servo will draw max? thinking of using 3-4 of these for a project purpose. i'm also trying to figure out if 2 of these would be able to turn a both ends supported shaft weighing roughly ~ 180-200 pounds. i'm trying for alternatives to step motors, this one if works shud be a clean and compact installation with an arduino controller. help greatly appreciated. thanks..
 Amie 3 points
Well converting 33Kg to pounds would be 72.75lbs. times 2 for each side of the shaft so 145.5lbs comparable withing the ~180-200lbs rang. I think it would be pushing it a lot. Now I'm not sure if these servos use metal gears or not.
 mikhail 43 points
these have about 3A stall current, you can hear a 3A bec struggle when pushing it to the limit. yes it does have metal gears.
