23t Spektrum S651 - 25t JX EcoBoost 21kg
Hi all
I've covered this before but it was in a video where I talked about a lot of other maintenance bits on my Arrma 3s cars. Thought it was worth doing a video just about the servo.
One of the main problems that people have with upgrading the servo on an Arrma 3s version 3 is that the stock servo has a 23 tooth spline and most servos on the market are 25 tooth. I have found that you can squeeze the 23t servo horn/saver onto a 25t spline with a bit of brute force.
In this video I cover how to get the old servo out and the new one in.
Hope this is helpful
Many thanks for watching.

Looking good Pete. Thanks for sharing bud. Nice work
Hiya Nick. Many thanks my friend. Hope all is well with you and yours :-)
Great advice Pete. Never had to do that myself but will definitely remember it for the future. Hope your weekends going well! All the best mate.
Hiya Rob. I haven't tried this with a Tamiya servo saver because they do give you the different sizes so you can actually do it properly. Many thanks for watching my friend. Are you at all tempted by these Arrma trucks? They are absolute tanks. Very speedy tanks!
You have a great set up for these videos when you work on RC's. Great editing and a well presented clear information. Top notch as always 👍🏼
Hiya mate. Yeah the thing that I have found very helpful is a bendy arm thing to mount the GoPro on. I can put the camera at any angle now which is helpful. You would believe how much I go wrong while making these but a bit of editing makes it look like I know what I'm doing! Many thanks for your great comments my friend :-)
@@PeteWylieRC I am keeping my eye out for a GroPro 8. I remember watching you review on them and the quality is great for RC.
@@DustyFingersRC Yeah the stabilisation is really good. You just have to watch out for that angle thing I was talking about on that video. The only issue I've had is that it sometimes doesn't switch on and I have to take the battery out and back in to wake it up.
Excellent video Pete . This will be my guide tomorrow. Thanks for servo saver fitting tip.
Cheers from BC
Many thanks for your great feedback. Hope you get it sorted ok 😁👍
Another nice video thanks Pete very helpful
Many thanks for your feedback. Much appreciated 😁
Hi Pete, thanks for the video. I actually watched it to get a little bit more info on the 25 tooth servo saver cause I had smashed the 23 on my big rock that I had put a kraton 6s servo on and it was in fact going out of center off and on and your video made me realize that I tightened down the SS to hard. That was really bothering me that I couldn't figure out why it was doing that and I was about to just buy a new 25t SS. So thanks a bunch 🤟
Hi there. It's great to know that these videos are actually helpful. Many thanks indeed for your great feedback and thanks for watching 😀
Hi Pete, hope your keeping well. Great servo tips there for the Arrma’s I’ll remember this little video. Well, we went out with our Arrma’s last weekend and yep we both broke the front suspension lower arms, got some replacements coming so that we can soon get back out there. The 2s packs performed well and definitely give you more punch, run time and no fading over time. They balance charged well for storage to either exactly 3.7v per cell or within 0.01v, so very pleased. I’ll give them 5 cycles each, before trying them at the higher 4.35v per cell charge. Keep well all the best 😉👌
Hiya John. I'm surprised that you broke the suspension arms on your cars. I did break 2 on my Big Rock but I was using the ramp and doing some pretty big jumps. I wonder if the long arms are less strong because the Granite has been beaten to death and I've not broken any arms. Anyway hope you are back in action soon. Glad that the lipos are performing well. Best wishes to you my friend and many thanks for your comments 😁
Good job jobbed mate 👍 Those servos are fantastic for the price
Hi Rob. Yeah I think it was Kevin Talbot who I first saw talking about how good these servos are and they are not expensive. Many thanks for watching my friend. Much appreciated :-)
Ottimo video utile ed istruttivo!mi serviva davvero. Grazie
Sono contento che sia stato utile. Molte grazie per i tuoi commenti
Good job and yes I agree much better and faster response 👍 and two days ago I received my first Arrma Typhon 3s and I absolutely love it ❤️ they really are great ,great !!! wow !!! Punch settings up to five and tore up the car park like a lunatic lol great upload mate thanks 🙏
Hey that's great that you got a Typhon. I do really love these 3s cars and also the maintenance is nice and easy. Worth checking the things that might need threadlock as mentioned in some of the other videos I did with the Senton. Many thanks for your great comments and enjoy your RC :-)
Hiya Pete - I think all the comments so far have said exactly the right thing about this video, clear, informative and very easy to follow. Top work, mate! Hopefully you will be in the pub supping a well deserved pint as I'm writing this comment! Enjoy the ale and have a great evening, catch you later my good friend. 👍😊
Hiya matey. Not quite at the pub yet. My mate doesn't finish work till 7pm so will be 8pm before we get there. Also sadly I'm giving him a lift and leaving the car near the pub so I can't have a cheeky one at home first :-( Anyway, thanks for watching and your great comments. I'm just going to go and freshen up and smarten up. Have a great evening my friend :-)
"Squash It On And Make It Fit".
Excellent Advice 👍
You should have that printed on a tee-shirt.
Brilliant information for a non 3s individual such as myself showing me what screws to undo in order to replace the steering servo 👏
Cheers Pete, hope you're well 😎
Yeah, if it doesn't fit then try a bit harder! You should get one of these so you can save the Tamiyas for less destructive RC'ing. Cheers for watching mate. Hope all is well :-)
@@PeteWylieRC I shall be tapping you for some information nearer my birthday for which one to get, possibly running a 24s with a trailer behind it to carry the batteries 😎
Thanks mate! Already bought that servo cuz the stock one stopped working after 1 month lol, aweome vid! 💪
Yeah I've got these in all my Arrma cars and so far no failures and it makes a big difference to the steering response. Many thanks for your great feedback 😁👍
Mine lasted a month too. Died right after rear plastic diff stripped.
I bought a spare front diff and a metal spur, because it's no fun having a broken Granite.
Great how to video 👍
Many thanks indeed 😁
Just did mine and worked out well , thanks again Pete . I found the tucking of the wires back in tougher than the servo re & re lol . One note , I got a 25 kg servo off Amazon and looked identical to the stock one BUT one thing . The 2 little stubs in between the holes , it was just a tiny bit taller than the stock one so had to trim those off flush . Have a good day Pete
Jeff in BC Canada
Glad it went well. Yes it's a fiddle with the wires. Not had a servo with stubs but good that you got it sorted. Hope you've got better weather than us over there 😁
Mine too. I'm gonna have to Dremel the casing, cuz it's too long.
I got the Zoskay (DSServo) 35kg and a 25kg.
Even the 25kg is so much better than stock. I just wish it wasn't mounted upside down like it was designed by some animal with no brain. 😂
Really clear and helpful....and proves you don’t need a 25t servo saver, which are often hard to come by. I’d never thought of upgrading the pivot ball, either. Thanks. Could I make a request and ask you to make one in the same series on diff maintenance and re-oiling ? I think many of us would find that useful and are intimidated by the perceived complexity of taking them apart ?
Hi there. Yeah I did this on my Senton and the servo horn stayed put. That plastic pivot ball does get worn in time so you get play in the steering. I was going to wait till it was loose but then I thought I might as well do it as a reason to take the ESC/Servo module out. Many thanks for your comments. I did a bit about putting oil in the diffs on this one - th-cam.com/video/ftYV8S1Xg-s/w-d-xo.html
@@PeteWylieRC thanks. I’ll make a point of revisiting that one, next. My Big Rock lost power at the back and is making a horrible grinding noise so I suspect the video will come in very handy
@@patmarcus172 yeah it does sound like you need to get it all apart to see what's up. Hope the video helps 😀
Goood explication !
Glad it was helpful. Many thanks for your feedback 😁
dude i put in a 25kg servo in my senton and it is a night and day difference. Best 20bux I've spent on that lil car. Thing takes a proper beating steering wise and now it is totally set for the forseeable future
Yeah it does make the car more responsive and worth the money like you say. Many thanks for your comments. Much appreciated :-)
@@PeteWylieRC heck yeah bro🤙 love your vids keep on keepin haha
Wanted to pick your brain on upgrading tires on the Maxx, I've seen peeps putting the ERevo tires on it and boy do they go good. Only problem is idk what to gear it down to. Especially whith where I am at this summer is going to be looking at 105°+ basically every day. So I don't want to overheat. And I'm thinking running 100w in the shocks, figure it would bring it down to almost an 80w
@@dank9288639 ooh I think you are outside of my knowledge there I'm afraid. I only ever had one Traxxas (2WD Slash) and also I don't live in a hot country. Where are you with those high temperatures? Don't think I could cope with anything over 80 degrees!
@@PeteWylieRC I'm in Southern California broskie, Riverside gets very hot during the summer. And it last from now till the end of November. It sucks
Ah right. Reminds me of that song It Never Rains in Southern California. I guess it must be true! Certainly not true in the UK where it rained for the whole of May. Got some nice weather now. Just under 70F which is enough for me 😁☀️
Thanks
Thank you for watching 😁👍
Hi Pete another great video. I’ve done the servo upgrade as suggested. Having issues with AVC since the swop. Works perfectly when AVC fully off. Steers hard right when turned on for no reason. Anything you’ve experienced with this servo previously? Thanks again.
Hi there. I haven't had that issue with any of mine but they don't have an AVC function. One of them has a gyro in the receiver and that works as expected which is to correct oversteer. Sorry I can't help but I think it must be a setting rather than the servo. Many thanks for your kind feedback about the video 👍
@@PeteWylieRC of course it’s only the Vorteks with AVC. I will attempt another re-bind and re-calibration and see if it sorts. Great servo by the way. Super quick and responsive.
make sure the receiver is flat and when you turn it on make sure it's on a flat surface otherwise it will randomly steer when you dont.
Hey Pete, how long would you say the stock servos last on these trucks? Very informative as usual, thanks for sharing brother and have you thought of changing out the tires yet? I’m thinking I’m gonna try out the granite tires on mine
Hi there. Hard to say about the servo as I have changed them out fairly quickly and they have gone into light 2wd cars where they are fine. I did try the Granite wheels on the Big Rock and they do work well. Haven't tried any from other manufacturers. Many thanks for watching my friend 😁
@@PeteWylieRC yeah I know you like to swap yours out to use for other vehicles, I’ve heard they go out fairly quickly but I haven’t had any problems with the servos on any of my vehicles, I was just wondering, the only issue I’ve noticed with my BigRock is the cogging but I think I know what’s causing that, gonna definitely get some extra granite tires for the big rock too, they do work a lot better, less traction rolling for sure
@@rcreviews9894 might be a dodgy ESC on your Big Rock? My original Granite one went like that and they replaced it. New one worked fine.
My typhon 3s servo stopped working on my 4th or 5th run.
7kg?? In one of THOSE!!???
I like that access hole. Well thought out that! 👍👍
Hey Mate, I've "jammed" Servo Horns on before!! 😳 Plastic onto Metal seems to have worked for me in the past, when I used to use Servo Savers!! 😋😂
I imagine that will work much better for you. It's certainly faster.
Cheers 🍻 Mate!!!
Hi Carmine. Yeah the supplied servo does seem a bit low on power but it was performing OK although the new one is much better. Yes brute force is always an option. I think that you do need a servo saver with these bashers that do jumps and have high speed crashes. Not tried them without though so I guess a high KG servo might survive? Many thanks for your great comments. Best wishes to you :-)
I agree Mate.... I still use Servo Savers on open Wheel Buggies, and anything for Bashing.
I just always use Kimborough... They're strong and have NO play!! 😁
I believe that Kimborough makes Aarma and TRAXXASS Servo Savers.
All the best to you!!
@@CarminesRCTipsandTricks ok many thanks for the tip my friend 😁
I bought the same servo and it works but it makes a very weird noise. I will post a short if you wanna hear the sound.
Oh right. Yeah I'll have a look and listen if you post a video 😁
I like it how it says "for grown-ups"
I'm 43, I hope that's old enough.
I'm not having the best time mounting my new Zoskay (DSServo) 35kg servo in my Granite BLX. This upside-down mounting and jamming a little screwdriver thru a tiny body hole to attach the horn to the linkage-doohickey part. I fiddled until that happened, but my servo is maybe 2cm too long. The screw holes on one side line up, and I can jam the screws in the other side halfway, but the steering is so off, and doesn't center.
I appreciate the video, any help I can get is great.
I may have to bust out my Dremel and do naughty things to the Zoskay servo casing tomorrow. I bought two, in case I butcher the first one.
Thanks. 👍🏽
Oh yes I think that 43 is old enough 🤣 The 'for grown up's' thing was because TH-cam had said that they were going to de-monitise anything that they thought was made for children. Anyway I'm not sure if it helps but I did another video recently where I take out that whole block with the servo/ESC etc. which might make life easier? th-cam.com/video/YwWFplMbMvQ/w-d-xo.html
I have a 2wd senton boost. My stock servo crapped out and wouldn't respond so im replacing it but id also like to improve the mount and delete the big plastic box its part of and have the esc sit flat on the chassis. Any options for an aluminum mount?
I haven't seen a metal servo mount for these. The plastic one is fine, even in the bigger 4s cars. Thanks for watching the video 😁👍
hi friend. is it ok if we use usual servo Horn instead of servo saver? I play my Arrma Senton for layout race (track)
Not sure but I think you will break the gears in the servo depending on how strong it is. Not something I've tried to be honest.
Have you changed your end points via the control? When you turned the car I could hear your servo when it over steered.
Hi there. Yeah I've adjusted the steering throw since this. Well spotted though. Many thanks for your feedback :-)
@@PeteWylieRC I'm not meaning just the dial on the steering trim. I'm on about the internal setting on the control?
@@mehimrc1314 No I just adjusted the duel rate. Does it not achieve the same thing of stopping the servo going beyond the steering limit of the car?
Cool servo upgrade Pete have you tried turning this truck or your Granite on its side to see if can do a side wheely you know what 007 did in the 1989 " License to Kill" flick with the semi truck?? LOL.
Hi there. Yeah you can sometimes get it to drive on one side for a bit but I don't think I've captured that on video. It's more luck than skill when it happens 😂
@@PeteWylieRC Just like 007 in that film and in many of all his flicks it's luck too LOL
Hey Pete so I installed this servo on my Vorteks and all works well except there’s a buzzing coming from the servo when I turn it. I’m assuming it’s binding somewhere? I tried backing off the screw that holds the horn down but it doesn’t seem to change anything. Have you ran into this problem during a new servo install?
Hi there. If it's only buzzing at the extreme ends of steering then you need to reduce the steering rate. If it's all the time then I guess you need to take the servo out and see if there is any resistance in the linkage when you move it manually. Also see if the servo moves ok when out of the car. Otherwise I'm not sure. Good luck!
@@PeteWylieRC this morning during breakfast I found a little barrel shaped spacer that looks like it would fit perfectly into the piece that sits between the horn arms. That’s gotta be my issue but I haven’t tested yet.
@@kez850 yeah that might be the pivot ball. It certainly needs to be in there.
@@PeteWylieRC hey Pete I appreciate your replies! It was 100% the pivot ball that fell out. Had no idea it was in there until I noticed it on the table. All is well now. Thanks again for your help, and this video!
Was it a good servo and do you recommend it
Yeah I have this one in all my Arrma trucks and so far none have failed me 😁👍👍
Very useful videos - subscribed! Pete, I got my 25t servo saver and servo today and the only way I can get it to centre is by adjusting the ST on the remote (STOCK ARRMA) Also, why is it that when I do full lock the angle is more extreme when turning left than right is this normal. I connected my stock servo just to check and its the same. Thanks - Noob to RC
Hi there. Did you power it all on and centre the trim on the transmitter before you put the servo saver on it it's central position? Once you've done that test that it moves the same amount in each direction before putting it back into the car. That should be it hopefully. Many thanks for your feedback and sub. Much appreciated 😁👍
@@PeteWylieRC All sorted now Pete, Thanks! where can I get those metal pivot balls which you put in the servo horn? thanks
@@km7101 Glad you sorted it.

@@PeteWylieRC Fantastic! Thank you. Can't wait to get it all together now and go bashing with the new servo!
Is it as easy as u made it look lol really wanna upgrade mine but I'm nervous the first time my slipper clutch come loose I over tightened it and it snapped the hex bolt off inside when I pulled off lol
Oh dear that's not good about your clutch. The servo change isn't too tricky. Good luck!
@@PeteWylieRC thank u 🙏👍
Hey pete, I've done this mod and for some reason my rig won't steer straight,it tends to go right a bit or left within a few feet every so often. I changed the servo saver to a 25t servo saver and it still tends to do this...any idea what it could be? Thx in advance for any info if you have any.
Hi there. Did you do the check of the servo saver function while the servo was out of the car? With the power on and the servo centralised you should be able to force the servo saver in one direction or the other and it springs back to the centre. Other than that is the servo working properly? Can't think of anything else. Thanks for watching the video.
@@PeteWylieRC i can go over it again...i don't have a 23t spline servo or servo savor...it's 25 to 25 that's what i don't understand...when i tried with the 25 to 23servo it kept pulling, now with the 25kg servo 25t spline ss it still does it.
@@humblebeast7232 Did you do the test that I do at about 3:30 in the video just to check that the saver is springing back to the centre ok?
@@PeteWylieRC i haven't been out with my rigs as of late but i am going today for sure to check. Thx Pete🙏 I'll keep you posted
Mate,if you look at the bottom of your Arrma you will see dots near 4 screws. Undo all the screws near the dots,the whole lots comes out a a unit. Much easier to work on then.
Hi there. Oh yeah I have done that way also. I think I mention it in one of the videos but I tend to use the method shown here. Many thanks indeed for your kind feedback. Much appreciated 😁👍
How good does this servo center?
Seems to center perfectly. Not had any issues.
Do you still water proof your receiver with hot glue
Hi. Yeah I still do that on all mine even if they are in a box because the boxes sometimes leak.
@@PeteWylieRC good!!! I did it to all my rc cars thanks to you 😁 I did it on the day I got my arrma senton
@@christiansrcs7789 Glad that was helpful. It just makes sure that they don't get water in. Voids the warranty but I don't think I've had a receiver that packed up in the first year anyway. Thanks for the feedback :-)
Hi my arma vortek turns by itself I am told its the servo can anyone help me please
Do you mean it's turning randomly as it goes along without you touching the steering?
Hate it when companies do silly things like use proprietary servo splines… I’ve never ever had a servo spline strip out, seems like a money grab just to make people buy one of their servos or servo savers.
Well I think that to be fair to them the 23t spline servo goes back a long way which is why Tamiya give you a choice of servo attachments on their kits. It would be nice if everyone could decide on 25t now though. Many thanks for watching and your feedback 😁
How long can this actually last for?
Do you mean the upgraded servo? I've got these in 4 of my Arrma cars and all still working fine. Thanks for watching 😁
@@PeteWylieRC Oh sorry I meant the servo saver. I'm planning on doing the same too and just wanted to save a few bucks from buying another saver :)
@@anong345 Oh right I see. Yeah I've done this on my Senton and Big Rock and the servo saver hasn't slipped round or anything. Those cars have been hammered on a regular basis. The servo spines sort of carve their own grooves in the plastic servo saver. Probably wouldn't work so well if the servo splines were also plastic.
@@PeteWylieRC That's good to hear. Thanks for all the help
Please Sir Change My RC Car Servo & Receiver, My Car Steering Problem No Left Right Working Car Only Drive. 😢😢😢😢
why did you not show the end result... the speed and response of the new servo. hahaha
Oh yeah that would have been good. I know I showed that in another vid I have done but I can't find it now. Just imagine an RC with nice fast steering 😂
Start modding nerf guns instead
I think I'm a bit old for Nerf guns. Having said that I might be too old for RC cars too 😂
@@PeteWylieRC just pick up a few 2nd hand electronic nerf guns u would be surprised how much u can do with them. I'm 41 still jerking around with RC and other things I don't care
@@scannaunderscore1 Yeah there isn't really an age limit to these hobbies so long as you enjoy them. Have fun with the guns :-)
Never force splines, that’s horrible advice
Hi there. Well I did this first about 3 years ago and still all fine despite driving these cars very often during that time. I appreciate that the best solution is to get the correct servo saver for your servo but this works and saves you money 👍
