I agree.. no one else explains anything. We all know what grease does.. duh. This is real info to make and educated decision. Hats off to you brother 🔥
You should really try first with factory setup, because oil weight can really change A LOT between cars. Like in a E Revo 2 its about 30k and 20M in the center so with 8k in the center the front tires are going to explode lol. Anyway good video for begginners it's always useful
i added 200k diff fluid to my redcat landslide 4s last night and boy was i not expecting it to be so loose in the rear,but it was putting a smile on my face because thats kind of what i wanted,great video bro.
I read in an rc article heaviest in the front, mid weight in the center and lightest in the rear. As in 500 rear diff, 1000 center diff and 1500 on front diff. This is for aggressive and still have control.
perfect video for all the questions I had especially the initial setup for beginners. actually seeing the individual differentials would have been a nice touch. thanks for the video!

@@Modelshoponline im using 1/8 Xray Xb8 nitro kit..i often using 3k,7k,8k,10k dift oil..also using 15k diff oil but rarely..im just race kit only in the track..if not running in the track i just put display in my rc workshop..😁😁😁😁
I have a XRT that's stupidly over powered lol but that was the goal.. but right now I don't know what diff fluid is in there.. I know it's stock. It has an 800 kv motor with max 5 running 12s.. I want to know ur opinion in going like 500k fluid in front, 20mil in center and 1mil in the rear. I'm looking for more of speed runs not so much of track.
I was amazed by the diff fluids in my X-Maxx 8s…. Front 10k, Rear 30k and the torque biasing center a whopping 20 million! Crazy! Changing all the diff fluids now.

My rc car understeers badly under high speed corners and my guess is when the weight transfers to the rear the center dif sends all the power to the front and do you think using grease in the center diff would help out on understeer Or would it damage it?
I've been looking everywhere for a clear non convoluted explanation on diff fluid and you nailed it! Thank you so much for taking the time to help educate us. Keep up the good work!
This video was very well explained I’m new to Rc Can u tell me what diff oil I should use in arrma typhon 3s which only has front and rear diff it’s a buggy but I use it on tarmac more and speed Thank u
Thank you for your comment Chris. Start with 50,000wt in the front and 5,000-10,000wt in the rear. Depending on your driving style and preference you can tune it from here.
RCexplained thank you for your time and knowledge, I will try this method , and will let you know out come so u have an idea the out come with this Rc too , thanks again .
just P. X I tried 50.000 wt - 10,000the handling was so so good I could stay on the power more in corners , it felt great . I like doing speed rounds tho and I lost 4 mph Which was a bummer, It made the typhon less noise to I have lots of video of typhon see what you think bud
Nice vid mate! Would be a 20m Center Fluid, 100k rear and 200k front setup good on the outcast 8s? I ask myself, will this setup force to much wheelies?
@@RCexplained hey bro, ive been using your videos to increase my knowledge, because they are excellent. can you recommend a front centre and rear diff fluid set up for truggy :1:8 scale converted from nitro to brushless, running on very high bite surface like tarmac. your feedback is VERY Appreciated.
@@RCexplained hi bro , many thanks for the feedback, because I'm using this truggy on tarmac, I'm looking for fast acceleration, with some good handling. I was going to go 7k 15k 4k . Original set up was 5k 10k 3k. Once again thankyou bro. Any feedback is appreciated.
My suggestion will give you more bite but can result in too much bite and getting sideways easy. Your selection will be easier to handle the power. Your decision completely depends on what your preference is and then adjust from there.
superb detailed description. learnt a lot. my 1 question about silicon diff oil is this: can I thoroughly mix 10ml of 10k and 10ml of 20k to get 20ml of 15k ? would save a lot of money as you would just need the lowest and highest and then mix everything inbetween...? budget bashing saves lives
Thanks for this video. I juts got my daughter a Team Corally Sketer for bashing around with me in my EXB Kraton and my mate with a V5 Kraton and the diffs are so aggressive. On gravel it just spins out even with mild throttle the rear acting like a locker with its 20K fluid causing it to spin out on her. The base set up you suggested is exactly what the Team Corally support said to use. Hopefully these changes will make it way easier to drive.. Keep up the great videos..
A video about ball diff vs gear diff might be also interesting! There are many threads about what is the effective/dynamic difference about those, and nobody seems to agree on the why, but tends to agree that ball diff is better at low grip conditions than a gear diff (even with low viscosity silicone oil). Maybe it's the left-right power transfer that it might be inherently faster in a ball diff? or maybe the gear diff oil changes propierties the faster the gears rotate, compared to the ball friction? I don't know why.
I think it would be a challenging video to make. I don't really see any advantage a ball diff has over a gear diff. Maybe it being lighter? There's a reason these are fading away and not really used in anything other then small RC's.
@@RCexplained One small advantage is the lack of gear backlash. Since it's just plates pressing on balls there's no play like a gear diff can have. A bigger advantage in my opinion is that when a gear diff starts to unload is becomes easier for it to continue to unload. A ball diff unloads at more or less linear rate. Last advantage I can think of is that ball diffs won't fade or change during a race unless you set it too loose and it slips.
Although it’s common sense and ties into your wonderful video I’m surprise ya didn’t touch on locked or spooled diffs and the 500,000 and 1 million fluids for the noober
Uh oh. On the recommendation of someone I got 500k for center and 80k for front and rear in a redcat Kaiju. Have I just screwed up the whole setup? 😳😳😳
Extremely well delivered video, your competence is awesome, I just purchased the New Arrma Kraton EXB with the Castle 1717 8S 1650KV setup, with a Futaba HPS-CB700 servo and I’ll use a 17th pinion. What Front/Center/Rear Diff oil weights would you start with as well as the shocks front and rear also. I’ll run it as an 8S so it may be a bit heavier than expected. BTW I’m not s huge basher or jumper I just like having the capabilities if I so chose.
Hey Cleveland Coleman, I'm not sure what the stock weights used in the new Kraton are. Typically I prefer to have the front and center differential heavier than stock. What I would do in your case is run the Kraton with the stock fluids to see how it performs and adjust from there. As for the suspension setup, here too I prefer to have a higher weight oil in the struts with stiffer spring rates. My setups are usually heavier than stock requiring stiffer springs with heavier oil. For jumping, heavier weighted oil and spring rates will help absorb the large jumps otherwise it will be easy to bottom the Kraton out on these larger jumps.
This is a cracking vid I've been reading up on this as I've got my first buggy that I fancy setting up for racing around I now see there is not really one ideal set up and it needs changing every different surface and it's going to take time to master the number for the different terrain you video is one of the videos that I have watch and can marry up with what I've read so far
Hey rc clan, thanks for the comment. You are definitely correct in that there is no real one ideal setup. I do tend to prefer a specific style regardless of what I am running. However I do change things up if racing a buggy vs an on road car for example.
I Have A Arrma Kraton V5, I Want It To Keep It From Not Doing Wheelies.. I Hate When I'm Trying Do Speed Runs Or A Drag Race, It Wheelie, Even When I'm Slowly Moving The Throttle...🙁 What Is Your Suggestion?
Believe that the offset in diff weights makes a more favorable and driver friendly car to control. The car is more forgiving with lack of skill from the driver. It’s almost like cheating. Yes, it’s all about making the fastest, best handling car to beat the next guy. But I think making front and rear a true 50/50 split like most true 4wd set ups creates a better driver. 50/50 is as raw and pure as it gets. Once the driver skill can keep up with that animalistic car, they’ll beat anybody any day. Anybody can drive a forgiving car setup and stay fast.
Hello, what weight oils would you recommend for a maverick quantum r on road truck 1/8 scale? I don’t want it to drift, I want it to hook up like a touring car. Thanks
I have a question. If you can help. You mentioned diff oils f5 c7 r3. Now the question I have is how come 1/8th oils are thinner than 1/10th. Would the following oils f5 c7 r3 work well in 1/10th
Great video. However I think that the car will almost always get the most amount of traction with the centre diff locked, regardless of the surface it’s running on.
Hi Mo, I see what you are saying. The same can be said for all differentials on the car. At the same rate, having a locked center differential and sending 50% of the power towards the rear end on a loose surface can be highly undesirable. Reducing the power to the rear wheels will increase the traction at the rear end and decrease traction at the front end. However, too much power on the front end will not result in abrupt power oversteer and loss of control. It can be a big balancing act dependent on personal preference.
@@RCexplained hello, if you would. How does the center diff transfer power to the front? If the diff is already unloading at the rear diff because its lost traction won't this just continue as it's open diff until the rear end finds traction?. If I lock the center diff, will this prevent unloading at the rear diff as power is distributed 50/50 with no bias giving best overall performance? -Mojave off-road only.
So lighter fluid equals easier to drive and not as hard on your motor to a point, heavier equals a lot of acceleration but less control and less sharp turning, heavier in front , I have a truggy with no center diff or slipper clutch , do I just re open my diffs they were nearly locked and miserable
I have a 2wd Traxxas Slash with a velineon vxl that is a street car. Im planning to swap out the entire transmission and im putting a hot racing sealed diff. What fluid size do you recomend?
@@RCexplained "correct units" wth are you even trying to ask? Yes in the front diff I use 50,000 weight FIFTY THOUSAND and in the middle I use 200,000 TWO HUNDRED THOUSAND weight, and in the rear 20,000 TWENTY THOUSAND weight... This stuff is THICK! When you have power running through them diffs from a Hobbywing Max6 1650 combo spinning huge Dboots Copperhead 2 tires you need the thick fluid not the thin runny stuff you talked about. So yes I am talking in "correct units"...
Confirmed, you aren't comparing the same units. Units in video are not wt. They are cSt. It's like comparing megabits to megabytes. More info in the description.
@@RCexplained dang dude really.... Your math is incorrect to begin with. So in reality you need to learn to do the fkn math I don't need to I know what units I am referring to. As well what I use is no where near the thin sewing machine oil you have in your diffs no comparison. Now get off your soap box!
I've never really gotten in to tuning my diffs and have always been the type to adjust to my RC rather than trying to adjust my RC to me. I've blown a few front tires and have realized that I need to put thicker differential fluid in the center. I have a few questions about differential fluid / grease. What is the difference between diff fluid / grease? I'm assuming that diff fluid actually goes inside of the diff, and grease goes in side of the diff box. Is diff fluid and diff oil the same thing and are two words that get used interchangeably? Also, you mentioned that 7k-8k is a good setup for starters on the center, but yet I've heard of people crazy numbers like 1,000,000 in the center. Why is there such a huge gap with those numbers? I can only assume that there is no universal rating system, where a number directly correlates to the thickness. Not every RC manufacture makes their own diff fluid, which means you could be running a Redcat RC with Team Associated, an Arrma with Losi fluid and so on. So with that being said, are differential fluids the same across all brands (similarly to car oil) in terms of the number to viscosity ratings? Or would 8k from one brand be thicker / thinner than another brand?
This guy is referring to small 1/10 scale buggies on a race track. I use 50k front, 20k rear, 200k middle however my RC is 1/8 Kraton EXB and has a HUGE 6th scale esc/motor combo turning HUGE monster truck tires. With the thicker middle fluid it allows me to wheelie easy. The brand of silicone diff fluid is of no worry if it is labeled as 10k it is 10k just like auto oil rating. Cheers~
now, how do you feel about all competition chassis 1/10th scale using a spool in the front? even the expensive ones.... RCexplain it please.. i have asked this so many times without a real answer anywhere, how can they compete with a spool instead of diff? is it because they count on the inner tire being in the air in sharp corners?
Great video thank you! You recommend around 5,000 weight front, 7,000 weight mid and 3,000 weight rear as a base. I’m trying to buy some oil but it’s only in CST, can you convert this for me? I see some people saying 5,000 weight is 50,000 CST etc is that correct? So I’ll need a 50,000 CST front, 70,000 CST mid and 30,000 CST rear to match your weight recommendation? Thanks in advance 👍🏻
There's no perfect conversion. Stick with a multiplier of about 10. It varies significantly from brand to brand. EDIT: I have updated description to reflect cSt recommendations. I may have said "weight" but meant cSt.
Doing center Diff on U4 Losi Lasernut, doing the 500K. will see how it goes. Saw another fellow youtuber use it and he likes it. You think its overkill?
It's not necessarily over kill. Really what it comes down to is personal preference. There is no right or wrong. I would say the same if you said you are using 2,000,000 in the center diff. Try it out and tune from there.
Thank you for the great video. Lots of good information. I am building an Arrma Kraton V4 6s piece by piece with many upgrades and I was looking for a little advice in my front middle and rear differential weight?
Hi Ed, thanks for your comment. You can try using 10k in the center, 7k in the front and 5k in the rear. This can be a good place to start. From here you will want to fine tune according to your own personal preferences.
Ed, Just to let you know, the Kraton 6S V4 comes with 100,000CST in the center diff and 10K front and rear. I just bought a bunch of different weights to try in my new 6S V4, but dang 10K seems really thin compared to "stock". Not saying it isn't sound advice, cause whom am I to question (first rc since I was but a child in the early '90's), just wanted to let you know where ARRMA starts out.
@@mainmanmustard My friend has Kraton like you and suggest me for Sledge which is similar 20/20/10 for our dirt track. Your setup can be similar. I had 20milion in the central before :-D He just seen my Sledge and make me to change. I finished build with Max6y bumper and better radio, but have still no time to test. Maybe today if weather will be good.
Hi I need some advice. I rebuilt the center diff in my Losi Tenaciy MT and used Lucas Xtreme Heavy Duty grease (green) to fill it and now almost all of the power is going to the front wheels. What is the issue? Is it too thick or too thin? What should I use instead?
Hi RocknRidin, Heavy Duty Grease is still way too thin. Use a minimum of 15-20 K weight fluid in the center differential. If you are looking for even more power sent to the rear end, experiment with 30K or higher.
I have a 1/12 scale truck and it isn’t the fastest but I mainly use it in moderate off-roady terrain. It only has front and rear diffs and I’m planning to put 15k in the fronts and 7k in the back. I wanted to know if that seemed logical for what I want to do with my truck.

You bet!
Nice video, but at 2:27, you're backwards on viscosity. A higher viscosity or more viscous oil is thicker. Lower viscosity is thinner or runnier.

Weight is dependant on size of RC. Your Mohave is not a light vehicle. Principles are all the same.

This is a cracking vid I've been reading up on this as I've got my first buggy that I fancy setting up for racing around I now see there is not really one ideal set up and it needs changing every different surface and it's going to take time to master the number for the different terrain you video is one of the videos that I have watch and can marry up with what I've read so far
Hey rc clan, thanks for the comment. You are definitely correct in that there is no real one ideal setup. I do tend to prefer a specific style regardless of what I am running. However I do change things up if racing a buggy vs an on road car for example.
Thank you for this video.
What if I don't have a center diff? I have an armma Typhon 3s .
Hi Scott, not sure what you mean. If you are viewing the video, you must have 1 of the 3 diffs talked about in this video.
50,000 weight what lol 😂
Great info. I’m currently setting my losi 8ight t diffs to 10-10-07
Excellent!
I Have A Arrma Kraton V5, I Want It To Keep It From Not Doing Wheelies.. I Hate When I'm Trying Do Speed Runs Or A Drag Race, It Wheelie, Even When I'm Slowly Moving The Throttle...🙁 What Is Your Suggestion?
very informative. well done.
Hey Cyclopsfpv. Thanks for the comment.
Video was perfect👌
Thank you Philly Dee!
Believe that the offset in diff weights makes a more favorable and driver friendly car to control. The car is more forgiving with lack of skill from the driver. It’s almost like cheating. Yes, it’s all about making the fastest, best handling car to beat the next guy. But I think making front and rear a true 50/50 split like most true 4wd set ups creates a better driver. 50/50 is as raw and pure as it gets. Once the driver skill can keep up with that animalistic car, they’ll beat anybody any day. Anybody can drive a forgiving car setup and stay fast.
Huge help! Thank you.
Then why does Traxxas use 20 million in their center diffs on e Revo? Being a dirt based truck wouldn't they want to use a lighter fluid?
Guy suggesting using 3k wt in the back, while im putting 300k in my shopping cart. Yep, professional
Hello, what weight oils would you recommend for a maverick quantum r on road truck 1/8 scale? I don’t want it to drift, I want it to hook up like a touring car. Thanks
I have a question. If you can help. You mentioned diff oils f5 c7 r3.
Now the question I have is how come 1/8th oils are thinner than 1/10th.
Would the following oils f5 c7 r3 work well in 1/10th
Great video. However I think that the car will almost always get the most amount of traction with the centre diff locked, regardless of the surface it’s running on.
Hi Mo, I see what you are saying. The same can be said for all differentials on the car. At the same rate, having a locked center differential and sending 50% of the power towards the rear end on a loose surface can be highly undesirable. Reducing the power to the rear wheels will increase the traction at the rear end and decrease traction at the front end. However, too much power on the front end will not result in abrupt power oversteer and loss of control. It can be a big balancing act dependent on personal preference.
@@RCexplained hello, if you would. How does the center diff transfer power to the front? If the diff is already unloading at the rear diff because its lost traction won't this just continue as it's open diff until the rear end finds traction?. If I lock the center diff, will this prevent unloading at the rear diff as power is distributed 50/50 with no bias giving best overall performance? -Mojave off-road only.
Awesome. Thank you!
You're welcome!
So lighter fluid equals easier to drive and not as hard on your motor to a point, heavier equals a lot of acceleration but less control and less sharp turning, heavier in front , I have a truggy with no center diff or slipper clutch , do I just re open my diffs they were nearly locked and miserable
Wow. Best explanation I have heard. Great details.
Glad it was helpful!
very informative video thanks. WHAT kind of oil should I use in my new ARRMA Typhon 6S v5? 1/8 scale. THANKS
These are the best rc vids period. Thanks!
Wow, thanks!
Great nice video you have answered my question
Glad I could help
I have a 2wd Traxxas Slash with a velineon vxl that is a street car. Im planning to swap out the entire transmission and im putting a hot racing sealed diff. What fluid size do you recomend?
Nicely put. I have a armor felony with a different rear differential which one will give me the more top speed 14/45 rear diff .15/42 front gear
I use wheel bearing grease in center 50 or 60 k in front 500k in rear exb kraton actually thinking about doing grease in rear as well
HAHAHA yea ok... I use 50,000 in front, 20,000 in rear, and 200,000 in middle. But then again I have a 1/8 Kraton EXB with loads of power!
Are you comparing correct units? Sounds like you are not.
@@RCexplained "correct units" wth are you even trying to ask? Yes in the front diff I use 50,000 weight FIFTY THOUSAND and in the middle I use 200,000 TWO HUNDRED THOUSAND weight, and in the rear 20,000 TWENTY THOUSAND weight... This stuff is THICK! When you have power running through them diffs from a Hobbywing Max6 1650 combo spinning huge Dboots Copperhead 2 tires you need the thick fluid not the thin runny stuff you talked about. So yes I am talking in "correct units"...
Confirmed, you aren't comparing the same units. Units in video are not wt. They are cSt. It's like comparing megabits to megabytes. More info in the description.
@@RCexplained dang dude really.... Your math is incorrect to begin with. So in reality you need to learn to do the fkn math I don't need to I know what units I am referring to. As well what I use is no where near the thin sewing machine oil you have in your diffs no comparison. Now get off your soap box!
Great Video!
Thank you!
I have a kaiju, what would you recommend diff should I use in my front and rear diffs ? Need help please.
Tyical 3? Have 10 cars and none of them has a Center diff.... 🤔
So clear and helpful, thank you.
Glad it was helpful!
Thanks for all your knowledge
You bet!
Thank you So Much! Needed this as my purchase arrived dry diffs! Can't wait to oil them up!
Yes sir, thank you for this great info.
You are very welcome
What weight would you recommend for the traxxas maxx front and rear diff mainly off-road driving
What weight oil would you recommend for a infraction in drag racing
I'm going to be snooping around here ah'bit!!!
But if you're poor, you won't have oil issues haha
I've never really gotten in to tuning my diffs and have always been the type to adjust to my RC rather than trying to adjust my RC to me. I've blown a few front tires and have realized that I need to put thicker differential fluid in the center.
I have a few questions about differential fluid / grease. What is the difference between diff fluid / grease? I'm assuming that diff fluid actually goes inside of the diff, and grease goes in side of the diff box.
Is diff fluid and diff oil the same thing and are two words that get used interchangeably?
Also, you mentioned that 7k-8k is a good setup for starters on the center, but yet I've heard of people crazy numbers like 1,000,000 in the center. Why is there such a huge gap with those numbers? I can only assume that there is no universal rating system, where a number directly correlates to the thickness.
Not every RC manufacture makes their own diff fluid, which means you could be running a Redcat RC with Team Associated, an Arrma with Losi fluid and so on. So with that being said, are differential fluids the same across all brands (similarly to car oil) in terms of the number to viscosity ratings? Or would 8k from one brand be thicker / thinner than another brand?
This guy is referring to small 1/10 scale buggies on a race track. I use 50k front, 20k rear, 200k middle however my RC is 1/8 Kraton EXB and has a HUGE 6th scale esc/motor combo turning HUGE monster truck tires. With the thicker middle fluid it allows me to wheelie easy.
The brand of silicone diff fluid is of no worry if it is labeled as 10k it is 10k just like auto oil rating.
Cheers~
now, how do you feel about all competition chassis 1/10th scale using a spool in the front? even the expensive ones.... RCexplain it please.. i have asked this so many times without a real answer anywhere, how can they compete with a spool instead of diff? is it because they count on the inner tire being in the air in sharp corners?
The rock crawler or climber seem to lock or use heavier diff
Awesome RCeXplained
Thank you just P. X! Appreciate the comment!
Great video thank you! You recommend around 5,000 weight front, 7,000 weight mid and 3,000 weight rear as a base. I’m trying to buy some oil but it’s only in CST, can you convert this for me? I see some people saying 5,000 weight is 50,000 CST etc is that correct? So I’ll need a 50,000 CST front, 70,000 CST mid and 30,000 CST rear to match your weight recommendation?
Thanks in advance 👍🏻
There's no perfect conversion. Stick with a multiplier of about 10. It varies significantly from brand to brand. EDIT: I have updated description to reflect cSt recommendations. I may have said "weight" but meant cSt.
is the grease protect the plastic gear of the rc differential?
What are you trying to protect the differential from? Differential fluid works very well.
can the grease can protect the crashing of plastic gear inside the differential
@@johnmarklucing7106 All the differentials I've used have metal spider gears.
Doing center Diff on U4 Losi Lasernut, doing the 500K. will see how it goes. Saw another fellow youtuber use it and he likes it. You think its overkill?
It's not necessarily over kill. Really what it comes down to is personal preference. There is no right or wrong. I would say the same if you said you are using 2,000,000 in the center diff. Try it out and tune from there.
How would these guidelines change if you have no centre diff? Still 5000 front and 3000 rear?
Correct
Thank you for the great video. Lots of good information. I am building an Arrma Kraton V4 6s piece by piece with many upgrades and I was looking for a little advice in my front middle and rear differential weight?
Hi Ed, thanks for your comment. You can try using 10k in the center, 7k in the front and 5k in the rear. This can be a good place to start. From here you will want to fine tune according to your own personal preferences.
@@RCexplained Thank you
Ed, Just to let you know, the Kraton 6S V4 comes with 100,000CST in the center diff and 10K front and rear. I just bought a bunch of different weights to try in my new 6S V4, but dang 10K seems really thin compared to "stock". Not saying it isn't sound advice, cause whom am I to question (first rc since I was but a child in the early '90's), just wanted to let you know where ARRMA starts out.
@@RCexplained on a infraction v2 what would you recommend in the front middle and rear Thanks for the video 👍
@@mainmanmustard My friend has Kraton like you and suggest me for Sledge which is similar 20/20/10 for our dirt track. Your setup can be similar. I had 20milion in the central before :-D He just seen my Sledge and make me to change. I finished build with Max6y bumper and better radio, but have still no time to test. Maybe today if weather will be good.
We want a spool for straight line acceleration lol
Very helpful and informative!
Hi I need some advice. I rebuilt the center diff in my Losi Tenaciy MT and used Lucas Xtreme Heavy Duty grease (green) to fill it and now almost all of the power is going to the front wheels.
What is the issue? Is it too thick or too thin? What should I use instead?
Hi RocknRidin, Heavy Duty Grease is still way too thin. Use a minimum of 15-20 K weight fluid in the center differential. If you are looking for even more power sent to the rear end, experiment with 30K or higher.
I have a 1/12 scale truck and it isn’t the fastest but I mainly use it in moderate off-roady terrain. It only has front and rear diffs and I’m planning to put 15k in the fronts and 7k in the back. I wanted to know if that seemed logical for what I want to do with my truck.
That can work well. It depends on the performance that you are after. Try it out and adjust from there.
