[@RayRiv73]

On the typhon 3s v3 there are 2 empty holes in front of each side of the motor module and you can put 2 m4 x 8mm button top screws that fit perfectly to where you cant even stick a piece of paper in between. This helps prevent the motor mount from bending.

[@njohnsonII]

The velcro mod is a great idea! Your videos are great, thanks for sharing.

[@martyshaw9143]

Thanks for the tips, I'll be doing this to my 3S stuff today before tomorrow's bash session. Love the channel, thanks for educating us RC newbs.

[@gihonda127]

Good video, I just got a Senton 3s BLX, and watching your videos really help in what to look for and what I'll need down the road.

[@nrd515]

On my and a friend's recently bought Granites, there was loctite on the axle screws, BUT, a couple of my hubs and one of his were loose enough to remove by my fingers. The loose hubs made us paranoid and we checked every screw we could get to without tearing the whole truck apart, and everything was fine.

[@DamienJoseph-kg9xm]

Thanks Razor, you have helped me with maintaining the fleet from day one.

[@wescat2]

Thanks for tip #1. I've seen you mention that on the ArrmaForum a few times and when I first started I had no idea exactly what you meant. This will help the beginners greatly. Thanks!

[@jimmyv1753]

Thanks for making this video. I’m looking for upgrades and mods for my granite. Which so far has been bullet proof.

[@monkeyrc7541]

These are all great tips! I am an experienced RC’er and i wouldn’t have thought of these unless something broke.

[@superratel7657]

Got a Granite, already lost a wheel (so threadlocked the 4), had a servo failure (upgraded with a jx servo and a 25t servo saver from yeahrun) and bent the motor mount (m2c upgrade on the way). That's 3 out of 5 already. Wasn't aware of the velcro mod. I'll try it. For the Hex, depending the the wheells you wanna upgrade there's also a 17mm hex adapter. But Louise MT tire range exists in 14mm hex. Got another tip for you : close the small holes on the chassis under the servo with a 3d printed cap or a piece of ducktape. It prevent small rocks and dust to stack under electro module. Thanks for your video, always great quality and straight to the point :)

[@RazorRC]

good suggestions

[@warrencooksey5603]

Hi Razor- One 3S tip I have is using the Outcast 4S shocks on the 3S. They fit nicely and very durable and I think better performance. It's super beefy compared to stock but still fits.

[@armandopace6113]

Mate thank you very much I've got the arrma vortex for my grandson for chirstmas and ordered spur gear and will be getting 12mm hex and fixing these problems. Again thank you very much and be safe 👍😁😁

[@craigbu7755]

Tip number 6,change the plastic spur gear for the metal upgraded one if you intend to bash n jump it hard,also the stock shocks bend pretty easily so if you don't wanna spend too much upgrading them just fit a senton front bumper for extra protection. Your velcro tip is genius by the way 😊

[@g3t0wNeD420]

When going from the plastic to metal and u buy just the gear to upgrade the gear make sure to add a 4th slipper clutch plate and a better screw.

[@samclingan1084]

I went ahead and bought the metal gear and a set of slippers when I ordered the car, cuz I burned thru so many plastic gears on my Kyosho nitro (& there was no metal option).

[@jerryvolpini7987]

A metal spur is a band-aid. Yeah, it's tougher but it will transfer energy to other parts of the driveline AND it doesn't address the real issue, which is mesh, mostly the result of a bent motor plate. Hot Racing makes a great plate but the M2C motor plate/brace combo is amazing. A metal gearbox is also a great option. I have the M2C pieces and, 4-5 yrs in, I'm only on my second plastic spur!

[@kevinlucas36]

@@jerryvolpini7987could you post links to the items mentioned. I would love to have your success

[@Funcentric]

#3 totally happened to me. Exact same thing. Wish i saw your video earlier. Seems understated but that's a pretty big design flaw of the Vorteks. Thanks for this video. Very helpful.

[@dodgymtbknee]

been thrashin the life out of my big rock 3s now a couple of months. only upgrade i found it needed was a dirt cover to keep stones out (as a stone killed composite shaft like a lathe) and your brilliant idea with the velcro.

[@EG-vy2lm]

I think it's worth mentioning for the people who have problems diagnosing stripped spur gears. If the plates bend your pinion and spur gear aren't alined correctly and wil strip out the nylon spur gear. Appreciate the info and upload, keep on doing what you!

[@thanumgaming]

Love the velcro tip! I'll def be doing that next time I've got the module out.

[@caseyqli]

I just bought this yesterday. It's my first rc car. I have no idea what I'm doing so your videos are very helpful!

[@eXo173]

Followed your instructions for my recently bought Big Rock. Also reinforced the body and set the slipper clutch. My drive shafts already had some Loctite on them.

[@jman0542]

This is a great resource, thanks for making this video. I hope Arrma realizes how much r&d you have saved them!

Great vid. I like the idea of witching to 12mm instead of the 17mm hub conversion. Thanks

[@user-or1uu7yt9n]

Definitely upgrade the servo before you even get started . Mine broke 3 minutes into my first run because I took a turn a little fast and rolled it. The stock one on mine had plastic gears .

[@JGRC512]

I was just looking at replacing my axle on my senton however, after watching your amazing video, I found the axle had in fact came unscrewed. Thank you! 👍👏

[@user-hg9sj9wz5v]

It’s funny I’m watching this video from 2 years ago, and I just recently, within a month, bought the granite and had this very thing happen while driving in my driveway. The rear right wheel just flew off and rolled down my driveway 😂 Luckily it was at a low speed. And just as you stated, I realized the set screw was still in place which made me feel like I’d won the lottery 😂 Anyway I also used thread lock when I reassembled it. Although I will admit, I haven’t done the other 3 wheels yet 😬 Maybe that should be my weekend project 😂

[@HarvesterOfPizza]

Great video. I just got my big rock today and the end drive shaft already popped off

[@_N4VE_]

thanks for the first tip i saw it mentioned in another video but nobody showed exactly HOW to do it 👍🏽🤙🏽

[@vincentbisket]

I just got me a Arrma 3s and this video was a big help

[@DanjaBis]

I just upgraded to the m2c motor mount, but I've had very good luck straightening my stock one on an anvil so far when I've bent it. I'll admit not everyone has an anvil lying around. I also drilled a small hole below the power module clutch gear to let dust out, but I now wish I'd seen this and tried the velcro first. Big fan of the AR550044 for tyres/wheels , they fit right on the stock hexes. Think they're off the granite.

[@jonroberts9367]

Very good tips. Wish I could have seen this before losing my tires.

[@beehave5405]

Hi Razor RC. Great video. I have a Kimbrough 124 servo saver now. Do you have a picture of how you filled yours down and which way up down you had the bolt and nut (m3?). Many thanks in advance.

[@robertjones3026]

Hello, great video by the way! Quick question if you don’t mind or even others from the comment section. All are welcome. Do you have any recommendations on the Arrma Typhon and the 12mm hex? I ordered some wheel axles for a Vorteks with hopes they’d fit. Thank you for your time!

[@FearlessTrailhawk]

Will be adding that velcro next time i jave the motor out...just not looking forward to re-seating it...it never wants to match the teeth on the rear and won't push on. I've found they have a huge weakness to gravel and small rocks. My first time out i spent more time clearing rocks from the steering servo than actually driving. We added a bunch of screen material to keep debris from getting inside and it makes outings sooo much nicer! We also had that issue with the axle screws...lol...until we loctited everything!

[@SnoriRC]

Followed all your tips EXCEPT thread-locking the drives to the wheels. Figured ARRMA must have sorted this problem now after 12 months of your video being live. Sure enough today front N/S wheel bounced off over the horizon!

[@CCxRC]

Great tips! That first one will save a lot of heartache

[@jerryvolpini7987]

Yeah, especially that right, rear side! First thing I tell people. It's why I go over an RTR before I ever run it (and why I like kits so much, lol)

[@theguyinthecomments9543]

[@davidalexander6837]

Great vid, I'm taking my 3s typhon apart now, the rear diff doesn't spin freely when the carrier is tightened....if I loosen the 2 screws it spins but has a tight spot. This as a brand new car and I heard it when I first drove it, is it OK to leave those 2 screws a little loose or what should I be looking for to keep the ring and pinion spinning free......thanks

[@fogcityrc4874]

good stuff here!!! Thanks for this!

I went 17mm hex and pro line badlands, love it

[@russellcottingham5185]

Yep... Ive lost wheels and used locktight, bent my motor plate replaced it with the hot racing, and smoked a servo 😅. I have a Typhon and a vorteks. I shouldve watched this a long time ago. Thanks for the tips. Ill definitely be using the velcro and switching to 12mm on my vorteks

[@saltylocal6917]

A few questions…doesn’t Hot Racing make a aluminum servo saver for the Arrma 3s? Also, is it worth wild to convert the wheel hex’s to 17mm instead of your recommended 12mm? More wheel options or less/doesn’t work??

[@alanlucas501]

How about swapping out the transmitter and receiver set? From the Spectrum to Flysky Noble NB4?

[@unknownknowns8379]

yo i keep grinding out the diff gears and input gear on my senton4x4 3s, whats a good replacement diff? like, could i use a granite or typhoon diff? im surprised the diffs arent metal. iv had to replace these diffs 4 time now.

[@rcleesd]

Great tips! The Arrma 3s lineup is the best value out there, in my opinion.

[@RazorRC]

Most definitely!

[@cheeznipsmagee2357]

RPM everything on a traxxas in order to bash. Only bent tie rods and broken a arms on my arrmas. Motor bearing replaced once due to a bent mount I didn't check. By far the best value. 👌

[@smarthandsomeguy]

I just (May 2021) received a v3 Big Rock. It had plenty of loctite on the drive shafts.

[@goreyboggs]

Any prob with Diffs? I noticed if you go to heavier tire you might start seeing early wear.

[@gregmancari4271]

RPM Granite arms do have plenty of clearance for the shocks in the vortex, so that could be an option too!

@Greg Mancari Thanks, good to know 👍

[@Clavitz1]

What street quality tires would you guys and gals suggest for the Vorteks running on the speed pinion? The mm doesn't matter

[@olafv.2706]

Thanks for this. Another essential upgrade in my eyes is: HOT Racing Aluminum Pivot Ball Set atf160b02

[@CookieManCookies]

In the latest rev of the drive shafts, they're epoxied on. But I prefer to pull em apart and use some medium strength vibra tight. (Mod 1)

[@S9RUT]

The only times I've ever bent the motor mount was when I sent it about 20-25 feet in the air and landed completely sideways. Other than that, I felt absolutely no need to upgrade the motor mount.

seeing the car crashing down onto the ground hurts you more than the car itself

[@S9RUT]

@@Howard25 you gotta make that "Ooooooo" face 😆

[@V8chump]

Seen guys use hot glue around their motor to give it a little cushion to keep it in place....given the motors not getting too hot it should be a good idea. Hot glue also peels right off with a straight blade screwdriver if you ever need to replace or remove your motor 😁

[@runnerbaba]

@@V8chump just use a rubber puffer you can find by Ikea and everywhere, these transparent round things with a flat surface with glue underneath

I have the same screwdriver but could only find the bits going down to 2 MM. Do you have a recommended set you like?

[@TheDistantChaos]

I shredded a spur gear from a small rock getting wedged under my motor. Couldn't have been there for more than 15 minutes and killed the spur gear. So I put a piece of foam gasket around the motor to prevent it from happening again

[@dv86sr54]

Nice video! Maybe you can try the carpet track again after these upgrades?

[@rcbears2229]

Yes, mod1! It happened to me just recently. The wheel just came off. It was a hassle screwing the axle part together but I now see I did it wrong. I dissassembled the axle joint to reach the screw.......

[@TheflyingkiwiRC]

Great Tips and relatively simple fixes to an already solid platform. Do you cover the motor module hole completely? That is you stick both velcro pieces together?

no, just the soft (loop) side

[@pdrc9344]

Hi Razor RC. Thanks for the good video. Apologies for asking, but I have a technical question. After my rear shafts popped out, I bought a full set of Allen's, to get the length for the drive shift screws. However, the metal of these was not as good as my short change stanly interchangeable. Could you please let me know the exact screwdriver measurement (metric or imperial) of the drive shift hex and also the same request for all the other Allen screws on the car (metric or imperial). Could you recommend a good hard metal set of screwdriver hexes for all of the screws on the Arrma Granite V3 BLX 3S. Thank you so much in advance.

[@RazorRC]

Metric, you need 1.5, 2.0 and 2.5. I recommend the MIP brand, they make a full set of all 3 for about $35-40.

What are the weird wire clips that come with the Arrma 3S? Anyone? Just curious I’ve been thru the book a few times and they aren’t mentioned or I’ve simply overlooked it. I use the same lock tight that stuff comes in a pump that is super nice and handy. I’ve had mine 3 months now. Have beaten it pretty seriously and haven’t had to put so much as a screwdriver to it. So that awesome. It’s due for some maintenance. Normally within a week or so I’ve destroyed driveshafts or smoked gears and bumpers. But this Arrma blx100 granite had been flawless.

[@grumpydude1598]

upgraded servo to a 35kg one just for fun, will also upgrade the esc soon since im on my thrid on warranty, they are just bad and undersized tbh. threw on the granite tires with a 15t pinion, it runs very well with those bigass tires on now :D but overall the 3sblx lineup is a tough little kit , cheap and alot of fun

[@coisnotpog]

I figured i would add my 2 cents in. For all the models the weakness i have seen that wasn't mention is the ball joints. Most of them have little flanges on both sides for mounting flush, and i have seen many break. Popping them out and replacing them with aluminum ones is very important imo. I am also not a fan of the shocks. I have not seen any of them break, but having the top eye built onto the shock body means a whole body replacement if it does break. The Prolines are expensive, but a very worth while upgrade if you plan on running it for a long time. The last one i have is specific to the Senton. The stock tires are pretty fragile. I blew one out on the 3rd run in a straight line on the dirt. A massive piece of it tore off. The whole bead was still very glued on as well. I figured this was a fluke, until it happened 2 more times the same exact way. On one of the front original tires, and again on the back with one of the replacements. The wheels are perfectly fine, but i moved to Proline tires, and have not had a issue since. The Armma 3s's are beastly, but the few problems they have is really annoying. To make the Senton perfect (imo) brought the price from $339, to about $450, but it is now a super fun and reliable truck that will out handle my buddies Slash 4x4 with an LCG chassis.

[@codydillenbeck4443]

Biggest mod/s I liked so far were the HR pivot balls, new servo, and aluminum bell crank. My BRCC is much more stable and easier to control at high speeds. 2nd was getting a new motor since the stock seized the bearings, I went with a surpass hobby 3665 3500kv motor and love it. There is virtually no more cogging on the esc/stock gearing, actually very impressed with the torque it puts out.
