How to install a new Servo in your Arrma 3S Typhon/Granite/Vorteks/Big Rock/Senton (tutorial) 

This video will be very helpful to me tomorrow as i install a new servo for the first time ever. I'm a noob and all I've ever replaced are diffs. I got a 35kg for a replacement, steel gears... Thanks for the helpful guide. Because Arrma mounted it upside down, it's a lot easier for me to follow this guide rather than have to follow a different guide, just upside down. Don't know why Arrma did it this way, but it was probably somehow cheaper, since their other puzzling choices (plastic gears) can be explained by thrifty-ness.

Great video! Really helped me with my new Big Rock. The RC community cannot thank you enough!

Just had the servo go out yesterday on my arrma granite s3. Thanks for the video, explained the process clear and easy to comprehend. Just hit the subscribe and notification button, lookin forward many more videos. Thanks Rob!

This video is incredible. Thanks you Razor RC. I'm installing the Hot Racing aluminum version so no cutting of the servo saver, but this video helped with my vorteks swap!

These kinds of vids are always appreciated. 👍

Wow, way easier with the correct drill bit. When I upgraded my Mega to a brushless it took forever because I was doing it all by hand... lol Good investment.

Thanks for this video, it was a big help. My servo went out on my BigRock. I got a similar servo that you recommended and used the included servo saver. Although I did have to grind it down to fit.

Awesome video! For the tabs on the servo to fit, I found it easier to just use a file to make the notches on the servo mount deeper so no cutting is needed in the future if I ever install another servo.

Great walkthrough and loving the background music. Though I wish they'd flip the servo upgright so minor adjustments with the servo horn would be less painful and also less prone to pebbles getting jammed in that exposed corner.

Wow the timing just replaced my son's servo last night. Might find a few tips to make it easier in the future and with the experience I have already I'm sure this will be helpful! Thanks Razor 👊

MST makes an awesome saver as well with 3 different springs and options for 23 or 25t servos

followed this to a tee and fit awesome!

My steering servo has just gone on mine wasn't sure how to do it , your video is spot on thankyou so much

Dope video thanks man now I can finish y build

Thanks razor glad you did the video

Thanks for the video brother

Nice guide. On your previous video I said I used a "yeahrun" servo saver from aliexpress. Quick feedback : it's garbage : the spring keeps poping out and it gives a sluggish feeling on the steering. Keep away from it. Kimborough seems simpler, is cheap and I can find it in a local hobbystore (arrma 25t is out of stock everywhere in my country). I'll give it a go ;)

Kinda confused why you took the whole part out to do that but it worked so that all that matters 👍🏾

I appreciate the video and got all the way to mounting the saver. What size bolt and nut did you use for the drag link?

very very helpful, fixed my granite today 👍 thx

how did that servo fit stalk servo saver, I have red version but is more tooth on it?

I have a new Arrma Outcast 4s v2.5 and the steering hardly works with the front-end stationary and on the ground. If i pick up the front end, steering works fine. Seems like a weak factory servo. Would this setup have enough power to last and turn this heavy pig? or is there a better servo worth trying.

Great how-to video Razor. Thank you for posting !

Thank you 🙏🏼

So here's a question for ya, with the receiver buried that deep in the car, is there a remote binding plug? Seems like if you want to use a new transmitter and need to get to the binding port it would be a MAJOR thing for something so simple.

So the old servo saver had a top and bottom arm to mount the drag link, but your new one doesn't, it only holds on one side, does that mess up the way the thing works, the old servo saver allowed the screw to just act like a pin, but the new one also puts a torsion load on the screw. Seems like that would cause extra drag in the assembly.

Hello! Sorry if my question is dumb, I’m just curious why you chose that servo saver instead of the Arrma servo saver? I purchased a new servo but didn’t realize I also have to buy the servo saver, so I’m trying to pick one. Thank you for your time. Your videos are really helpful

My Big Rock steering quit, no collision. Replaced with new servo, no response. Radio is working but steering does not respond. What am I missing? Cheers!

do i need replace servo saver if i install the 25kg servo

Hello did you use a servo tester before hand or only how you centred it on this video? My Granite servo crapped out so I’m putting in a DSSERVO 25KG and this is my first time wrenching on it. Thanks 🙏 much love Cheers 🍻 brother

what drill are you using? I want one

Do you find the kimbrough servo saver makes the steering better as i have a kraton 4s v2 and when i go to steer on short grass the servo saver just gives and hardly no steering so im looking for a much tighter servo saver

I watched the video a second time just for the catchy music. "Everything's Tuesday" by Wyshm Gosselin.

Any AVC issues? I did this to my vorteks 3s with a 25t tactic and my truck just turns in whatever direction it wants and it keeps going. I turned avc all the way down on the radio to see if it would stop and it did, but the steering is a bit slow compared to the original 23t servo.

How is this servo holding up? Need a new one for my big rock I’m shopping around 👀

I have a senton 3s v3 and I ordered a savox 25t servo as the replacement for the stock one, can I reuse the original servo saver on the truck or do I need to order a 25t?

Good video. I appreciate the fact that you used the correct tooth servo saver. I have seen some clowns just smash the 23 tooth on a 25 tooth servo. @ RCusa201

did you have any issues after installing after marke servo. I put one in my wifes vorteks,and now the steering is backwards and it turns on its own without me turning the wheel.

I was waiting for you to connect servo back so I could replicate as struggling on my kraton and video ended nooooooo lol

lol I will need this video soon when I get my senton 🤣

show it work

I was hoping you showed the install....bummer

Good guide. Poor protection of screws of motor mount and servo mount from rocks, sand, water and other dangers. #r/Crappydesign

All that shit for a servo lol wow

Can do without the Irritating music
