I installed this center diff and both spiral cut gears in my stampede 4x4, those spiral cut gears are so beefy compared to stock. Super impressed by the quality of these parts.
@John Lujan I would guess its the front diff, you might have some messed up gears. Hitting reverse puts more pressure on the front diff and causes the extra noise.
One thing you should have mentioned is that if you change either the front or the rear diff gears to the spiral cut, that you have to also install the spiral cut gears to the other end. The spiral cut gears are a different ratio than the plain gearset and can make for some awkward running. I did that on my brothers Stampede 4x4 thinking they would be the same ratio, but the spiral cut are geared to spin faster. I should have known as it is the same concept in full scale vehicles between spiral and straight cut.
I really enjoy your videos! Please run these on a track , maybe try running it with sc race tires , it’s the next best thing to do with all the upgrades it has :)
Ive had terrible experiences with aluminum part upgrades. plastic is great, it flexes and doesnt bend. Im hard on my vehicles and anytime ive upgraded parts on any of my trucks(going back to savage 25, flux, now the rustler 4x4 and erevo mini) it seems like spending more and then you bend something and its a huge money sink. I usually do RPM arms, and bigger shocks/heavy oil but leave the rest plastic.id love to hear from some people with builds like this that drive their stuff hard.
I agree with most of what you are saying. I tell people all the time to skip the ultimate version and get a BL2-S, then upgrade the motor and esc if you're no longer having fun at 2s speeds. I would still upgrade the center drive shaft to aluminum right away as well as upgrading the motor mount if you upgraded to 3s. Everything else i think the Extreme HD Kit is better than aluminum, even the drive shafts in that kit dont get ruined using self righting on a Rustler.
devilicous yea I think the real advantage the rusty 4x4 has is it’s lcg chassis but I still think the stampede 4x4 would be more fun because it can do more w more ground clearance
Plus when you install the spiral cut gears vs straight cut gears. It be quieter wont have that whine to it. Ever put car in reverse and it make that annoying whine.
Unless you put some TIM between that motor and motor plate you aren't going to shift that much heat. How about a series with off-brand upgrades? Maybe build a second one and compare the two?
I love that I found this video just yesterday, I was watching a video from the jang from ultimate rc.com, and he has a shape shifter pede 4x4 as a Rustler 4x4 💪🏻😎that video was uploaded May 8, 2011
Thijs The main reason for this series is to show what’s available for this truck and how parts are installed and what their benefits are. You don’t need everything shown. Use the info to pick and choose what’s right for your application.
@@redblue40rc33 just get a castle motor runs much cooler without the need for fans. The Velenion motor is good and fast but runs hot. Im running 120A Firma ESC which has a built in fan and is crazy fast but makes the stock motor very hot close to 200 degrees.
So does a guy have to worry about setting gear mesh on the newer models. Got 2 4x4 rustlers recently for my boys first one was just the basic 4x4 and the next one a few weeks later was the VXL version and they have a plastic clip that goes into that slot has a few different screw holes for different sized gears just tighten it up and says should be set. Is it best to eleminate that piece and set it?
Off the wall question, but what weight oil do you run in the GTR shocks you have there? I have the GTR shocks on my rustler and am running 50 weight now. I’m not sure if that is working well, so I’m thinking of going with 40 weight but wanted to see what you were running. Thanks!!
Hi. Your videos are great so I wondered if you could help me. I have converted a Cen GST 7.7 to a brushless 4S electric motor, which is fine. But, this has a central gearbox, where the reverse was servo controlled. I have converted it to work, in a fashion, but there are still difficulties with running the car I hear I can install an open center diff and eliminate the gearbox, so the motor pinion drive will mesh directly with the center diff, which then connects to the front and rear dive shafts, so the motor then has direct drive. I cannot find an instruction video on how to do this. Do you have any videos or links to step by step instructions on doing this. Or, can you email me the instructions and the parts I will need to make this happen. The reason I want to do this is because the gearbox is now broken and difficult to repair, so having the open center diff, which is easy to access and maintain, would be much more appropriate for my needs. Really hoping you can help and thank you in advance for any assistance Martin
I have a Slash 4x4 with a 1/8 scale 2650kv motor, running on 4s with MIP X Dutys. I'm still using the factory front and rear diff gears. I have ran it hundreds and hundreds of times over the past 5 years and I have NEVER broken a diff gear. So.... do you really think these "upgraded" diff gears are really doing anything for a set-up with a stock VXL motor, other than lightening your wallet?
Matthew Foote yes, i upgraded the gear pinion and broke the rear diff. After that i ordered a new one and put it in there. After my first run with the new diff it broke again so i think they are a bit weak in the rustler 4x4
Hey bud! I’m looking for the solid axle monster truck kit you reviewed awhile back.... I can’t find it though. Can you help me please with the brand? Thanks brother. Subbed also
Whats better or stronger I should say? Ultimate slash or rustler 4×4 vxl? I'm having hard time deciding. I want to buy that truck right there. Ill pay 700 for that truck maybe more. Where can you buy fully decked out cars like that?
The Slash and rustler are pretty similar in durability, speed and overall quality because they share quite a few parts. Part of the fun of rc is that you can wrench on your cars and pick and choose what parts you want and customize them. You can make it all aluminum, or all red, or mix it up. Good luck!
Took me about a week and no problem now. It was the front hood clip for me, getting it to latch or slide under the spot it needs to go was a slight pain. I do like it a lot better the clips. I could never keep those on my old revo.
When tuning center diffs, a thicker oil will allow more power to go to the rear, and a thinner oil will allow more power to go to the front. Also, the center diff shown in the video is the same one used in the Hoss (although I think the oil used may be different).
I don't like aluminum when it bends it doesn't Flex back like the plastic and had to be replaced when plastic breaks you can glue it for a temporary fix and keep running your truck you can't do that with aluminum
@@popwall4297 top of the line electronics for a 10th scale is 300 alone easily. I paid 80 just for saxox servo 1256 tg and another 200 for hobbywing max 8 system. 400 for the traxxas vxl 4wd or 300 for 2wd build is decent and will last forever on 2s and a little while on 3s. 700 aint shit. Some 8th scales cost 2 grand after you bullet proof them with all that m2c cnc aluminum shit. After all rpm suspension mods, quality body, gtr shocks, Mod 1 gears & upgraded transmission, set of tires. I might be over 800 and that doesn't include batteries. Thats another 100 easy for decent ones. I prefer gens ace or smc. 1000 is easy to do on a rc car if you want it to handle 6s and hit over 100 mph. You can run max 8 system in this heat on 4s with low temps as long as you want. Spend 300 and it will be broke in possibly one run and recommend keeping it on 2s and 3s for short runs under 10 minutes
I just bought a used traxxas rustler vxl 4x4 but I don’t understand why the chassis is very low almost in the floor . How can I lift the chassis like yours or al list level?
Who takes the rustler to a track an races it? Lol do they even have a class for it? Its way behind the times of a stadium truck class. Hell the wheels are way to big. This is a little e revo basher thats it. No where near teckno tlr and ae. haha
Jeff Bryner People go to the track just for fun, to run laps. In my years in RC, I’ve seen plenty of friends hitting tracks on off days, driving monster trucks on tracks, basher trucks, rally cars. RC is about fun and doing what you want to do in order to enjoy the hobby. I applaud tracks that allow bashers to have fun on tracks, it turns some into racers at their own pace. Might want to think about the broader picture next time.
@@rcdriver oh thats cool. usually off days there is racers practicing at my track and they dont want some person in there bashing around with a monster truck or something smashing into them while there practicing and tuning for race day. Even on race day the novice class gets a certain amount of time to practice by them selfs between heats and are not allowed on the track after that.
center diff means removing the slipper clutch, unless you ride carpet without jump, it is a terrible idea, worst idea i seen so far on slash coming from traxxas

Back to the civilian life again after a short training with the USMC, so very glad that your channel still around.
JMO OPS Awesome to have you back here watching our videos. Thank you!
@@rcdriver not a problem sir. Keep on racing!!!
Great! Now go run it on that dirt track and show us how it handles with the center diff and 30k rear fluid. Wanna see how it does. 👍😁

I like the plastic better instead of breaking it comes back to its original shape if the aluminum bands you have to replace it

Nice upgrades fromTraxxas...keep em comming...
I did the same motor mount mod on my 4x4 VXL but I went with the option from King Headz since it uses a larger bearing than the Traxxas one.
Can you also do a how to vid on alignment for rustler 4x4 VXL?
Wish the metal diff had plastic spurs. You need to upgrade to hardened pinions to use steel spurs.
Loving the blue and Orange
I just used pure black grease inside my rear diff and a mix of 50/50 50k oil and black grease in the front. 😁
the exact video i needed thank you

@MrMKnigge I don't use the self righting feature anymore. It was neat the first couple times but the stress it puts on
watching this series has made me realize i don't need one of the new rustlers...i did all this to my stampede 4v4 lol....even has a similar stance
devilicous yea I think the real advantage the rusty 4x4 has is it’s lcg chassis but I still think the stampede 4x4 would be more fun because it can do more w more ground clearance
Worlds most expensive Rustler 4x4. But hey it looks cool. Lol

Yeeee got here early :) been following your build and making mine similar but blue and green parts
I'm upgrading to a spektrum brushless motor and esc for 1/6 into my 4x4 stampede
Motor plate on my erevo get very hot... so don’t underestimate the heat dissipation.
Unless you put some TIM between that motor and motor plate you aren't going to shift that much heat. How about a series with off-brand upgrades? Maybe build a second one and compare the two?
Hardlydan it does transfer heat it gets to the temp of the engine itself. I have the plate and i checked with a temp gun.
Great video!
Love the vids always
Nice rustler
So basically, the truck is finally the way they should have made it to begin with.
Pretty much! Upgrading is half the fun though.
Great video. I wished you would do one on a Kraton 6s
Arrma is doodoo.

I wish that i got the money to do things like This, i got the normal 2wd rustler and there is now a absima brushless motor in it.

👍Great video what shocks are you using?
I went with RPM A arms and GPM steel axels. Also strc motor plate. You are missing a engine heatsink /fan to add to the cooling.
supboy666 Temps did get high on a few runs but not critical. But a fan is a good idea for many.
RCDriver_Online i run a 14T pinion and 3s and most days here are 90+ degrees so I have integy dual fan heatsink to keep it extra cool.
Hot racing fans on my ESC and motor....ice cold runs
@@redblue40rc33 just get a castle motor runs much cooler without the need for fans. The Velenion motor is good and fast but runs hot. Im running 120A Firma ESC which has a built in fan and is crazy fast but makes the stock motor very hot close to 200 degrees.

What has been the total cost of this project so far?
Evan Fuller nothing! Thanks to the sponsorship! Ha
Probably like the price of another rustler
I had hoped he would include pricing with the parts he showcases, it's the only thing missing in his videos imo

Is there any locker options for the rear diff?
all the rear diff's i have pulled apart have black grease in them not oil.
So if I get this stock it will distribute the power evenly to all 4 wheels? And how many teeth does it have?

Is that center diff good idea for bashing and jumping? Or is ir better to leave the slipper for that usage?
For bashing and jumping, I would leave the stock slipper, especially if you're running offroad.
Do you mind sharing what diff oil you used?
Should put it on an indoor track and then when the weather is good edit in the bashing footage.

Does anyone know the part number for a rebuild kit for the center diff? Like the gasket and o rings?
is the body hard to put on 4x4 vxl rustler because i'm thinking about buying one?

I was told that the did that you got can only handle 2s. Is that true?
RCDriver_Online How can I bias the power to the rear. Thinking about the new Hoss center diff will it fit in
When tuning center diffs, a thicker oil will allow more power to go to the rear, and a thinner oil will allow more power to go to the front. Also, the center diff shown in the video is the same one used in the Hoss (although I think the oil used may be different).
Does this center diff also work with the Slash 4x4?

Aluminum is better except for a arms
Too bad they dont come ready to run race spec ready. Id pay 700 for that rustler and im poor
Well for 700 you could easily build a fantastic rig.
