We're installing some upgraded steering components into the Big Rock to try and eliminate some of the sloppiness and add some power to the system. The stock servo is 7kg we're installing a servo nearly 3x as powerful.

Check out the links in the description, I always include links to the installed parts and I include links to many items of my kit. I get lots of messages about part numbers and where I purchased something - it's always in the description!

@emustang89able Год назад

I use all the exact same parts and I absolutely agree that these are the best upgrades

@kylegeldmaker Год назад

I've never had an issue since installing them. I haven't gotten around to the bellcrank yet but im probably going to tear her all the way down for a good maintenance soon.

@NorCalark 3 года назад

Justin to clear up the difference in plastic adapters that come with the kit, if you look on the back you will see small letters on them and they correspond to the tooth number. 23 tooth has K, S and J stamped on it for KO, Sanwa, JR. 24 tooth has H for Hitec. 25 tooth has F for Futaba. It doesn't matter what brand it is i just wanted to add what the letters corresponded with, whats important is knowing what the spline count of your new servo is.

Thank you. I’ve been trying to get that servo saver on for a while now!! Watching you struggle was rather satisfying as I too struggled with it lolol. Glad you figured it out though.

@kylegeldmaker 3 года назад

Willing to struggle, I think that's my RU-vid brand 🤣. Next is the bell crank, that should be a just as satisfying for you lol

@lukerecore3211 Год назад

Great video bro, because my stock servo just shit the bed on me. But i ordered a 25kg and this will make it much easier to install my servo.

@kylegeldmaker Год назад

Mine is still going strong, I don't think you're going to be disappointed

@JimboHurt Год назад

Hi i hope you see this comment. I have a big rock v3 and it has a stock 23 tooth servo. When i get this cheap red 25kg amazon servo is it 25 tooth? Is that why the hot racing horn in nesecarry? Justy trying to understand. Tysm either wayt.

@kylegeldmaker Год назад

Basically yes, if you don't drop in a servo with the correct spline count then you'll need to replace both components. I wasnt able to find any drop in replacements for the Spektrum (S651 I believe) so I picked up a whole hit racing assembly. Its worked ever since I installed it without any issues. I keep meaning to make a video replacing the stock steering rack but it's never down for repair 😁

@patrickobrien6648 2 года назад

The brand is Feetech FT5330M, and they're all metal servos.. at least the 35KG is.. I doubt it's 35kg, and they're kinda slow, but still better than most hobby RTR's, I put a Reef's 299LP in my Arrma Senton 3S, it's fast! :)

@kylegeldmaker 2 года назад

I was looking at the raw 500. I'm really interested in the control of that model, but it's very expensive to jump dirt piles lol

@brianu33 2 года назад

My servo broke and I replaced with factory one. Stupid I know. In the box there were screws and spacers. Any idea where spacers go? I didn’t see any when taking mine apart

@kylegeldmaker 2 года назад

They go on the top between the bottom of the servo and the screws that hold in the servo. Let me know if that's confusing, I'll send a photo

@@kylegeldmaker can I assume they were already there from Arrma. I didn’t see them when I replaced my servo. I had the nut fall off that held servo saver

@wescat2 3 года назад

Nice vid. I have the 25kg servo on my desk. Waiting on a 25T saver to come in stock. I see yours is 270 degree. Did you have to flip the steer button for left/right? I'm sure you know, but for those that don't make sure you set end points.

@kylegeldmaker 3 года назад

Hmm, now you have me intrigued lol. I purchased a 180 degree servo, infact I just double checked the order. I'm going to double check the servo 😎. But to answer your question directly, I didn't have to reverse the steering and I definitely did reset the end points.

@dannynunez4705 2 года назад

Hey bro I install the 25K on the big rock did u had to changed the ST/R because the turning left/right is backwards?

@kylegeldmaker 2 года назад

I didn't have to, but it's fine to just change the switch. You could also rotate the servo housing 180*. That should work too

@mesostinky72 3 года назад

The Hot racing one may be iffy. I’ve heard the basic Traxxas plastic one works and same for Kimbrough savers. You can see a bunch on servocity website as well. My brand new big rock servo got stuck turning it Right only and now I have to take it apart and see if the servo saver is dead or if the threads just jumped to the right. Arrma has been selling garbage servo for years and I’m seriously disappointed to have to even do this after only 2 packs.

@kylegeldmaker 3 года назад

I've been using the HR saver since this video and I haven't had any issues with it. I'm sure at some point those plastic adapters will give way but until then it's worked out pretty well. I'll check out the Traxxas and Kimbrough ones when it does give out. Thanks for the tip!

@mesostinky72 3 года назад

@@kylegeldmaker glad to hear it’s still working. I guess truth be told none of them are supposed to last forever. I think the Servo saver market hasn’t kept up with the Servo market. Savers seem to be the same while you can get a 200oz servo for $17?now.

I’m about to buy a 130 dollar servo for my big rock should I?

@kylegeldmaker 2 года назад

I would say there's probably better things to spend your money on, but, the beauty of RC tinkering is the parts will fit other models. If it were me, I'd probably buy a 20-30 servo and spend the other $100 on maintenance items or possibly a motor/esc upgrade. Maybe even some wheels/tires.

Hi, can you link the name of the servo horn? The new big rock and granite have horn with 23t instead 25, i am looking fo the old v2 horn (code 25T - Ar340151) but is difficoult find it

@kylegeldmaker 3 года назад

The one I used is the Hot Racing horn (there's a link in the description). The main reason I did that is basically because the issue you're having. There's way more 25t servos and horn available. Swapping to a 25kg 25t servo really opens up the options.

@kevosrcadventures9019 3 года назад

On my granite the steering just went out completely at first it was jittering and then go back to center I called Verizon they're sending me replacement but I'm going to make the upgrade did it do that they told me the board on that servo I guess it's bad.. and thanks for the video it helps out

@kylegeldmaker 3 года назад

I haven't heard of many issues with the stock servo, but it's an easy upgrade and not very expensive. Let me know if you have any issues.

@drknight27 3 года назад

Similar situation. I bought my son an Arrma Granite Brushless. He ran it for 2 days and the stock steering servo went out. No response from the controller. We went to the local hobby store purchased a new upgraded servo and installed it. Truck has worked fine ever since. I don’t think the stock servo has enough torque if you run the truck in the grass.

@billboyer1025 3 года назад

Hows the steering rack? thought about getting it for my granite. did it take alot of slop out?

@kylegeldmaker 3 года назад

I haven't Installed it yet, but you're the second person to ask. I'll do a big rock update over the weekend.

@micikho1 3 года назад

Hi friend, I use arrma senton 3s v3 blx. Need to replace new servo. Is there any servo that fit with original 23t servo horn? Maybe around 10-15kg metal servo digital

@kylegeldmaker 3 года назад

Hi, there's some Spektrum models available that are 23t. They cost a little more for less power, but if you don't want to replace the servo saver I think that's the most economical choice.

@micikho1 3 года назад

is it durable if we use usual servo Horn instead of servo saver? I play my Arrma Senton for layout race (track) planning to get the JX ecoboost high voltage 35kg

@kylegeldmaker 3 года назад

@@micikho1 you might have to play around with some custom mounting positions to eliminate the servo saver but it's probably durable enough for a race condition. I would not use that for bashing or off-road stuff.

@miketye2805 2 года назад

I used a shiftrc XB servo and installed it with all the factory horn hardware ect. Works just fine. Shift Rc servo are the best!

I used that exact Servo saver setup, plastic adapter.. and it's stripped out on the first run

@kylegeldmaker 3 года назад

I've had mine for a while, I haven't had any issues. Evidently there's a marker on the plastic adapter that is supposed to match a specific servo type. Maybe you had the wrong adapter type.

Look on the transmitter for the steering reverse switch, it should say ST/R. It's next to the power button. Flip that sucker and you should be good to go

@@philiplibby7536 that's strange, I have this servo in pretty much every vehicle that has a standard size servo and I've never had one get hot. I don't believe the BLX100 can control BEC voltages, but I'll check. Outside of voltage or a faulty unit I'm not sure what could have happened.
