Traxxas Mini Maxx 4 Gear Diff Update & Slipper Clutch Install! Full Build Video - 3s Lipo Ready!

[@GasBrakeSim]

Hey JP thanks for taking the steps we needed to make this a more enjoyable truck . I pre ordered one and almost got a refund but seeing these videos by you has given me faith. Ordering all the parts as we speak, picking up the mini maxx later today! Cheers brother !

[@ultrarchobbies]

Super glad JP was able to get this updated and the goal was to help everyone who bought the new Mini Maxx that maybe having issues!!

[@brokenbirf]

No problem at all. I actually enjoyed doing this and i hope everyone can benefit from this video.. I appreciate the kind words.. enjoy the truck!!

[@joshuathomas6275]

@@brokenbirfFirst off, I want to say thank you for sharing your knowledge/expertise in this area. I just bought my daughter and I each our own Mini Maxx and I discovered this issue after my order was processed. It’s been a long time since I was in the hobby (my last truck was the T-Maxx TRX 2.5 which I still own). What is the purpose/ benefits of the slipper clutch in this setup? I genuinely am unaware. Is it necessary or will the diff front addition and rear swap be close to the same? Thank you from Michigan!

[@Sparkfist1]

I put on the wheel hubs, jato tires, and rustler wing on today. I also put in the VXL 3s. This is how the stock mini max should have come! I need a wheelie bar now.

[@llcj27]

Bestes Video ever, Danke für that awesome Instruktion.......👍👍👍👍👍👍

[@ultrarchobbies]

Thank you so much for watching and leaving a comment! Glad we could help!

[@mikewoodsy]

I just finished doing this, thanks for sharing this with us. Mini works great now

[@ultrarchobbies]

You are very welcome, glad we could help out and get peoples trucks back up and running!

[@markkumollari43]

Cool. I'm doing the same thing to mine, just waiting on a few parts to come in yet. Hello from Sault Ste Marie ON 👍🇨🇦🤠

[@ultrarchobbies]

Thanks you checking out the video and leaving a comment! Heck yeah a fellow Canuck! 🇨🇦

[@bkfracing8025]

🎉 happy rcing from MICHIGAN 🤘🏽🏁

[@G35Jeesh]

How the truck should have came. Traxxas might as well hire you for the engineering side of things lmao

[@ultrarchobbies]

We do disagree we were hoping for a ton with the little car but hopefully this helps people continue to have fun and make a massive upgrade for the platform

[@HoffaJedi]

Shouldn't have to do that.. Traxxas missled us .. Should have a recall and not state it's 3s capable.. Your videos are appreciated regardless.. cheers

[@ultrarchobbies]

We 100% agree, this is for sure not the ideal situation by any means on something brand new out of the box. But we are hoping this helps to keep people up and running with there new Mini Maxx and keep them having fun in the hobby.

[@Noldu5]

I agree, this car has turned out to be one big lie from Traxxas. Im truely disappointed with Traxxas on this, and i like Traxxas. Several years of hoping and waiting for a mini Maxx down the drain for me. Im suspecting they will come out with a vxl version that will cost probaly more than double of this

[@MacGecko86]

Great video. Thanks Jason!

[@ultrarchobbies]

Thanks for watching!

[@murraybraun11]

Great video! I’m going to run mine stock but it’s good to see how easily it can be upgraded. Thanks JP and Ultra for posting this! BTW, what parkade did you film the running footage?!

[@ultrarchobbies]

Thank you so much for tuning in! JP took it down to the market mall parade or to his significant others under ground parking for the building. I will double check and we will let you know!

[@tat2man68]

awesome video and breakdown of the mini maxx. what is the part number for those jato wheels and tires? thank you.

[@ultrarchobbies]

Thanks for watching and leaving a comment. The part number on the wheels and tires for the Jato are - TRA9073

[@juanrodarte9795]

hello, great video! do you think it would be a good idea to put 30 in the front 10 in the rear to prevent wheelies with 3s? Thank you!

[@ultrarchobbies]

Thanks for watching and leaving a comment. This is right from JP "The manual shows the front diff using grease and the back diff using 30k.. I just followed the user manual as a starting point.. I will definitely tune things with different oils as i use the truck more.."

[@WHiT3ST4R]

I hear stripping gear in hard acceleration on mine. But the spur gear is top shape. Is it the rear diff problem ? Only run about 45 min on 2s lipo.

[@jimpaulbarcena4259]

Is the slipper came assembled already at traxxas?

[@ultrarchobbies]

Traxxas does offer a complete slipper clutch assembly but at the time of filming this video there were none available

[@SoCalCrawlers]

Good Job 👍

[@ultrarchobbies]

Thank you so much!

[@gees5563]

Awesome video very informative 👍. Sucks that it didn't come out the box like that.

[@ultrarchobbies]

Thanks for watching. Yeah 100% agree but at least we have hopefully found a great way to solve some of the issues and make a large upgrade at the same time and keep people having fun with their new mini maxx

[@blrrd7193]

what’s the part number for the hubs you converted?

[@ultrarchobbies]

Thanks for watching and leaving a comment, the hexes JP used were Traxxas 6856X from the 4x4 platform

[@jamesblankenship9373]

I like that rear wing. What are the parts necessary to fit it? Can you make a video about it? Thanks

[@ultrarchobbies]

This is a 4x4 rustler wing 6721. I can see if we can make up a video about that

[@DutchRuhder]

​@@ultrarchobbies please do

[@christopherzatalokin8652]

Amazing.

[@ultrarchobbies]

Thank you! Cheers!

[@Hungrybird474]

If a man thinketh, he ll come up with something good 👍

[@ultrarchobbies]

Thank you!

[@jesusrosasrc214]

I figured this out the instant i saw the 10scale drive train they promoted with it and since the gears on the maxx are similar of that to an erevo so is the xo-1 to the slash and them just promoting the 10scale is because the 10scale gears they would use would be the same one for their own 10scale diffs

[@ericfellers1970]

I have a question your parts list show 2 sets of rear diff gears but the front pinion gear does not match the rear pinion did you reuse stock pinion on the front diff? My front pinion where the drive shaft slides on sheered off somehow so no reusing mine but just looking for little more clarification

[@ultrarchobbies]

Yes we have to reuse the front pinion that comes on the stock truck as unfortunately nothing in the Traxxas lineup will use that style pinion or driveshaft setup

[@WM84629]

Do Traxxas not make a shorter driveshaft? Will you need a shorter one to fit the center diff?

[@ultrarchobbies]

Unfortunately the Rustler 4x4 will be the shortest center shaft available as of right now until the correct one for the truck gets released by Traxxas to fit the center diff or slipper clutch. Both the center diff and slipper clutch will require the same shorter center driveshaft shaft.

[@WM84629]

@ on the Traxxas website under the center diff it says use either 10757 or 10762 which are the standered size plastic and metal drive shafts. So it’s a little confusing?

[@ultrarchobbies]

@@WM84629 There are 2 parts required if you do not do the diff mod we talk about in this video, we did not have to use TRA10762 as the pinion from the XL-5 diffs allows us to use the double flat spotted shaft from the slipper clutch or center diff. The parts Traxxas needs you to upgrade to go to either the slipper clutch or center diff are the following - TRA10757 - plastic center driveshaft or TRA10757X - metal center driveshaft TRA10762 - rear pinion that allows the normal style double flat spotted shaft from the slipper or the center diff which the Mini Maxx doesn't use with the out of the box direct drive setup

[@eme4289]

How much would it cost to make it like this?

[@skyhawk21]

So how much is all that to upgrade a truck that was advertised as being 3s ready????

[@grumpygrandpa3640]

Would the 40t spur fit instead of the 38t ?

[@ultrarchobbies]

With the overall dimension of the 40t spur being bigger than the 47t stock spur we felt it would rub the chassis and possibly cause other issues

[@grumpygrandpa3640]

@ thanks for the reply for future reference where did you get those dimensions from please s I couldn’t find them anywhere thanks

[@brokenbirf]

These dimensions wont be on the product pages or website.. We took a digital caliper and physically measured the outside diameter of a 54 tooth, 52 tooth, 50 tooth 32 pitch spur and found that all of these measured too big to fit in the chassis.. using the stock mini maxx 47 tooth spur was our benchmark to compare the maximum size that we could dimensionally fit in the chassis.. So our only other option was to look at mod 1 gearing from the revo. We measured the 40 tooth mod 1 revo gears and found that it was also too big and worked our way down till the 38 tooth mod 1 spur and that had a small enough dimensional measurement to fit in the chassis without rubbing.. We then sized a 16 tooth pinion that would get us pretty much in the same ballpark as the stock 20/47 gear ratio and the results are as you see them on the video.. Enjoy!!!

[@grumpygrandpa3640]

@@brokenbirf lol can I just have the dimensions of the stock spur please I’m not going to use the stock diffs nor the sane ratios as stock in the diffs hence why I’m asking for the actual measurements in mm if you can would be helpful

[@bkfracing8025]

@@grumpygrandpa3640stock ratio is about 2.3 and that’s 20 t Pinion and 47 t spur 38 spur and 16 t pinion ratio is 2.4 which is actually better

[@hughjanus5518]

Learned my lesaon with the 6s X-maxx that too had diff issues. All these issues with the mini maxx made me decide to wait to grab one that comes up on marketplace in a few weeks after Christmas. They're not worth the 269.99 they're selling them for and the more people who buy them the more this will happen.

[@momentarylapsofreason]

£280 hear that includes VAT 🇬🇧

[@daig1984]

Excuse me sir, what tires do you run on your maxx v2? Thank you 🙏

[@ultrarchobbies]

We have been using the MT-Mcross belted 3.8 tires from Louise RC

[@rc_jamm]

Question why wouldn’t you do 30k diff fluid in front as well just asking I’m doing mine as we speak but I have hobbywing in my mini maxx

[@brokenbirf]

The manual shows the front diff using grease and the back diff using 30k.. I just followed the user manual as a starting point.. I will definitely tune things with different oils as i use the truck more..

[@FrankKerssenfischer]

👍

[@Noldu5]

Seeing Talbots video where the motormount broke off during bashing was a bit of a letdown, but it really got a beating during that jump tho. But the motor mount seems to likely be a problem during bashing, i aslo dont like the way they covered the pinion so its hard to get the proper mesh

[@GHOSTBROWNz]

Kev is Cool n All but Kev a jackAss who DGaF He Destroys Everything on purpose lol 😂😅 Tumble wumble

[@eme4289]

I was so looking forward to this car. Even years before it was released I was hoping they would make a mini sized Maxx. But they dropped the ball on this one. It has too many problems and not at all durable like Traxxas’ previous vehicles. Blown diffs, chassis breaking, body keeps coming off, garbage electronics, etc, etc, etc. and then on top of all this, what do they do? They raise the price. A wltoys or Mjx hypergo is leaps and bounds better than this at 1/4th the price.

[@nahi6690]

Ya my diffs blew 1st pack on 2s

[@SteveP636]

FYI you don’t have to install the center piece,that’s specific to the X01 and not used on other models that use this diff.

[@brandonharvey5996]

There’s already a diff like this for the mini maxx. Shows it in the parts list tra10780

[@ultrarchobbies]

We thought the same thing as well as on most sites they say bevel gear, but at one time on the Traxxas website it mentioned in the description that it still uses the planetary gears inside. It however looks like they have changed that description so it may have changed (fingers crossed it did), but we haven't received any parts here in Canada yet so we cannot confirm or deny the change.

[@brandonharvey5996]

@ I have picture proof on a fb post that they are bevel gear diffs. Someone opened a new set to see. That part number is an upgrade part.

[@JohnSmith-ef8nr]

So really this truck costs £330 after you fix the diffs, and you still need to add the motor and esc for 3S. Just buy a MT10 and save your money.

[@ultrarchobbies]

We don’t disagree we just want to make sure anyone that may have bought the truck already and broke it can still have fun with it before all of the parts become available. Plus do a little bit of an upgrade at the same time

[@zip-tieracing4307]

How about you take the shims out put the top cover on then try and move it back and fourth the top cover locks it in your doing that for no reason

[@smrdmr1]

2 Complete HD diffs from Traxxas are $59.00, all this costs $56.00 just FYI

[@ultrarchobbies]

You could go that route as well just need to change over the ring gear as the normal VXL ring gear makes the mesh too tight as well as you need to retain the front pinion as no other truck in the 1/10 4x4 line up doesn’t use that style pinion

[@kennethmoore737]

Truck doesnt even need 3s....... thats whats crazy they need to redact the 3s statement smh

[@advancedwallstructures1756]

Not sure why Traxxas didn’t just do this from the beginning, they could have used parts they already had. Instead they spent R&D inferior parts and ticked off a lot of their customers with misleading advertising.

Just so you know I had this figured out all most two weeks ago and I didn’t put it on my utube you should not be giving this away you Owen a hobby shop you should be building them and selling them

[@ultrarchobbies]

That is awesome to hear that you had also thought of this as well!! Our main goal with this series is to give back to the community that supports us and ensure that they can have fun with the new Mini Maxx after it may have broken and stock parts seem to be an issue and hopefully solve it once and for all.
