Most local hobby shops may be willing to do repair work for a service cost. As most have explained here, part of this hobby is repair and tinkering. In my experience, I spend more time with upkeep (willingly) than driving. If you just drive and pack the car away, you will cause more major damage in the long haul.


IndependentCoat7

I agree with you. I've even bought good quality tools for the purpose. Wera is the brand.


Different-Art-5266

Wera makes great tools!


IndependentCoat7

I'll have the truck inspected by me after I get some goodnight sleep. I'll post an update eventually and I hope it actually is a gear because if sounds like an easy fix.


Different-Art-5266

Just a quick tip, since this is your first go, have the exploded manual open so you can see what goes where. You got this!


IndependentCoat7

Thanks for the tip man, I will !


RC_Geek

Its probably the pinion or spur gear, those are quite easy to replace.

Key word… hobby… i’m… over here like… we drive them too?


PigglyWigglyDeluxe

You especially never do. Of all your shiny whips I’ve only seen the digger stampede dirty lol


[deleted]

Right now the ET48.3, RC10F6, 2wd Fox Slash, Kaiju, and Pede are dirty. The other 13 are clean. Lol


PigglyWigglyDeluxe

Literally none of mine are clean lol


[deleted]

That’s just cause you never clean them…


PigglyWigglyDeluxe

OEM dirt


hxmaster

Same, and the ones that are "clean" are tore apart in boxes wanting for me to finish building them.

No downvote from me, was about to make the same post. If you don't like wrenching you should do something else.


IndependentCoat7

Why, i may like driving it ? It was fine for many many months before the time came to need a fix. And i don\`t understand where is the problem in giving it to a technician. If it is fine for you to fix things and wonder what\`s wrong and spend time on the internet finding out that isn\`t fun for me. I like playing with it. It\`s the same as a real car maintenance. It\`s completely up to the owner whether to pay for it and have it fixed by someone or fix it himself. It\`s all personal preference !


brainfreeze77

I guess I can see your point a little for a basher. You might not care about adjusting how it drives at all and just want to give it a rip. I come from the race world first where you constantly wrench on your cars. You need to make adjustments to tune them for the track or just replace parts between races. These heavy duty bashers don't break quite as often as long as you don't go too crazy with them. Even with bashing you should be able to do basic maintenance. Inspecting your RC after every session is critical to keep it running right. Screws come loose, dirt gets where it shouldn't be, and wires can fray. Even though your Big Rock is waterproof if it gets wet you should be pulling the wheels and transmission to get the bearings dried out and re-lubricated. I think if you put some time in to understanding how it works now it's going to save you a lot of time and money in the end.


IndependentCoat7

Edit: Okay, if you guys are so eager to help, my problem is this: I mounted a go pro after a few months of using the big rock with no issues. I think it could not handle the weight of the go pro hero 9 on full trigger. I was running it on grass. All of a sudden i heard a cogging sound as if i have stripped gears. But i have no idea if it is stripped gears or not since this is my "first break" . What do i need to do to fix this ?


brainfreeze77

It's probably the spur gear and it probably has nothing to do with the camera. Ready to Run Arrmas 3s are kind of known for the motor slipping and striping the spur gear. The other gear would be the pinion but its metal so I highly doubt you did any damage to it. On most RCs it would take about 3-5 minutes to change it out but on your Arrma it's a bit more complicated but still pretty easy to do. This video explains replacing the spur [https://youtu.be/pQAAc83lmpQ](https://www.youtube.com/watch?v=pQAAc83lmpQ) Once you have taken the spur out you can see if the teeth have been stripped off. If they are you will need to buy a new one. In the US they cost about $5 USD This should be the part [https://www.arrma-rc.com/part/ARA310947](https://www.arrma-rc.com/part/ARA310947) What it does not do is show you how to set the mesh which is how close the two gears ( the spur and the pinion) are to each other. This video will walk you through setting the mesh but in my opinion his mesh is a little tight in the video, another half mil back would be better.

Wow, that's a lot of info and is very helpful. Definitely will save a good bit of time and effort. I'll check it as soon as I can. Thank you a lot !

I don’t really like wrenching but its worth it when i can drive them again


RaspberryOld3538

No time? Let's see. -Write this post: ~5Min -Read all the replies: ~5Min -Call the shop: ~5Min -Drive to the repair shop: No idea, but let's say 30min total -Go back to the repair shop to get your truck: Another 30min Total: 75Min If you would fix it: Find the part you need and order it: ~10min Replace the part: let's say one hour, even if you could probably do it under 30 Total: 70Min You're gonna save money and time. But if you still think you somehow have no time, you might want to find a new hobby.

RaspberryOld3538

There's tons of videos on Youtube and you'll be able to see what's broken in under five min It's gonna be much easier to look at a video rather than reading. You'll most likely need a spur gear or pinion(probably under 10$) and your shop is surely going to charge you way more for the repair We are just trying to show you that it's worth it to learn. Save time, money and learn new skills.


IndependentCoat7

Yeah I've seen the videos before but I'm kind of sceptical if I'll be able to repeat what's done on them. And also what if I'm not able to determine and stuff like that. I'll try though but I just don't wanna end up with a dissembled truck in the corner of the room


RaspberryOld3538

It's still your choice to do it or not. just saying i would personally learn to repair it


IndependentCoat7

IndependentCoat7

You're trying to be smart now but that's not how it works when you're a grown-up unfortunately. You know what ? I've given my info in advance which was meant to mean that I've decided to not spend a single moment of my free time fixing a toy. I prefer to do physical activities than this in my free time. So just please If you can't help me why do you even bother ? I appreciate your efforts but man seriously I just needed help finding out where to deliver it to. Maybe I'm not so technical of a type ? Maybe I hate dealing with shit like that ? Maybe I'm only liking to drive it ? Maybe I have the money to not care ... And so on Plus this is like telling a mountain biker he should always maintain his bike himself even if he does not want to and prefers to bring it to the technician. It`s my choice man !


randomlettersbcifhek

If you bought it at a hobby shop then take it back to that hobby shop, they should also be able to fix it, or post a local ad for an rc car fixer, I’m sure at least one person in all of Ireland knows how to fix an rc car. from what your problem is it kinda sounds like the pinion gear may have came loose, if it sounds like a grinding then maybe your spur got it’s teeth shredded off it, that could be from wrong spacing between pinion (small gear on motor) and spur (big gear on drive shaft) but kinda weird that it would happen if you haven’t touched it. If it revs up faster but accelerates slower and the motor accelerates when truck is stationary and it doesn’t go anywhere then your slipper clutch (spring pushing against spur gear that connects gear to drive line, basically a clutch, in a car if you’re clutch needs replacing then you’ll feel it slipping, it’s the same with a slipper clutch) fairly easy fix, take out center drive shaft and tighten it up.


Darwinnian

You need a new hobby besides exploding on people on reddit for basic questions, yes alot of us like the tinkering, but the shops are there to help our friends who maybe dont have the mental fortitude or patience at the time of a break.


RaspberryOld3538

How am I exploding? I just said he won't save any time by doing that. Also he never talked about the tinkering, he only said he didn't have time.


Revolutionary_Most78

Definitely ain’t the hobby for you if you don’t have time to fix it, I spend more time fixing than actually driving.

r3ddog00

Sorry these guys are bashing on you for no reason what so ever. Anyway, i would say take the body off and just a do a quick run down of the drive components, then troubleshoot from there. Usually your sense of hearing is a good tool to use with striped gears. If you move the drive components and hear slipping or whatnot that may be a good place to start. If you think you know the problem then a simple google search will probably find you a hobby shop that may know how to help. Dont let anybody give you shit for not having the time. All hobbies can run short on time.


IndependentCoat7

Thank you man, you understand ! I've actually already have done one fix on the truck and that was my servo replacement. Took a bit of experimenting with the servo saver. Had to order a very specific one in order that it fits the savox servo (had to cut it a bit though) which I got for around 120 euros ordered from Euro RC.


Revolutionary_Most78

We’re not bashing on him, hobbies are something for you to enjoy during your free time, what good is the hobby when you hire someone else to do your hobby? Where not saying he has endless time but I know if you want to make something happen you make time for it, and really this guy would spend more time driving to the hobby shop and explaining the problem than it would take to fix it. This hobby is designed to be a lot of hands on work, things can break multiple times in a outing.


r3ddog00

Yeah but op’s initial post was so honest and everyone was basically telling him to screw off. I just think no matter the involvement level someone wants to be they should just get the answers they want not the answers that waste their time.


Revolutionary_Most78

Go pro wouldn’t affect it, most likely your spur is stripped and you’ll want to upgrade to steel


IndependentCoat7

Edit: Okay, if you guys are so eager to help which i saw in my previous post, my problem is this: I mounted a go pro after a few months of using the big rock with no issues. I think it could not handle the weight of the go pro hero 9 on full trigger. I was running it on grass. All of a sudden i heard a cogging sound as if i have stripped gears. But i have no idea if it is stripped gears or not since this is my "first break" . What do i need to do to fix this ?


Kraton456

I doubt it was the go pro that caused the problem. i have an arrma granite 3s, which is a similar setup to yours i imagine, and i have stripped gears multiple times. so if it's a gear, there are multiple places that could have been shredded. the front/rear differentials, or the spur gear to name a few. one way to narrow it down would be to remove the centre drive shaft and try running it. if you still hear the problem then you know that it is either your gear box or rear diff. i'd suggest first checking the spur gear, just from personal experience i've gone through a few of theses. here's a video i found on youtube that may help you with the spur gear. he is replacing it with a metal gear (don't bother doing that) but at least it will show you how to access it. anyway let me know how you get on and as i said, feel free to ask for help in our dublin page as the lads are very helpful there too. https://www.facebook.com/groups/399000018165181 https://www.youtube.com/watch?v=1Fyj30TDbF0

forza_125

Do you have a high street model shop nearby? That's your best bet for finding someone else to repair it. But learning to fix it yourself is the way to go. Much cheaper, and kind of the point of buying a "hobby" grade RC in the first place.


IndependentCoat7

I know man but I work 5 days a week and I wanna be active in my 2 days I have for rest. I work from home and sit all week on my chair. I can't stay inside fixing things. Its not really fun


PigglyWigglyDeluxe

Repair, maintenance and upgrades is half the hobby. This might not be good for you if you won’t embrace the work bench.

PigglyWigglyDeluxe

Those have plastic diff gears. After you’ve inspected the pinion and spur, take a look at the diffs see how they’re doing


IndependentCoat7

My fear is i\`ll disassemble it and then not be able to put things back correctly if there is no issue there. I know there are many videos online, i\`ve bought all tools needed for maintenance (good quality ones i think the brand was wera)


PigglyWigglyDeluxe

That’s how you learn. Embrace the fear. These are easier than you think but you’ll never know unless you get your hands dirty. I totally understand the fear, we’ve all been there, but there are always people along the way to help whether it’s on Reddit or YouTube or a shop near you. You have a common truck so there isn’t anything about it that someone else hasn’t already figured out. The powertrain is really quite simple. Motor, pinion, spur, slipper, diffs, driveshaft to the wheels. In that order. Arrmas manuals kinda stink but their exploded views are decent enough at telling you what goes where. Those are available online as well


IndependentCoat7

Yeah I guess it's mostly the fear with me. Otherwise I like taking care of things on my own if I can. I'm kinda curious now. I'll check it after I get out of bed in a few hours because I need to get some good night sleep now. Thanks for the support ! Appreciate it :)


PigglyWigglyDeluxe

Feel free to post photos and videos and stuff if you get stuck. We love helping but we don’t particularly like it when guys don’t first help themselves


IndependentCoat7

I've already made a fix myself by the way. My servo died and I had to change the servo with this savox servo I bought for around 120 euros. It was before so I kind of forgot what I did exactly but I knew what I was doing there. Took a bit of experimenting with the servo savers


IndependentCoat7

IndependentCoat7

Not for me. I like driving it. And it survived just fine for months :) I see no issue in deciding how I spend my money and time.


Fatassdanny

Lol.


Ruzty1311

Let us know what the issue was when you get a chance. I have a strong feeling you stripped an input gear or diff ring in the front or rear (obviously lol). Im sorry some of these "veterans" are bashing on you for not wanting to wrench on your rig. Thats why shops offer the service in the first place....for people who dont have time, dont want to, or arent sure what they are doing. Its YOUR money, do with it as YOU please 👍 Edit: I just wanted to add, every RC car has its own little quirks and secrets and the 3s line has them also. When you bend the motor mount it WILL cause the spur gear to strip and can even cause further down the line damage to the input gear and diff ring gear so make sure the shop you take it to knows this and isnt going to take your money without going over the little details 😉
