[@-jmg001-]

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.

[@RCexplained]

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.

[@marinearmeni]

@@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.

[@asproductions6400]

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?

[@g4ry26]

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

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.

[@RCexplained]

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.

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

[@kevink8153]

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.

Hey Kevin, thank you for the comment. You are correct, I didn't catch this while editing. It should have been said as "less viscous" in the video.

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?

It's really a preference of the driver. I do like the center diff to be quite solid. Give it a shot and see how you like it.

[@surfside75]

Weights seem lite. My Mojave comes with 10k 100k 10k . Changing to 50k 200k 30k -so good, I came back to watch again. Thanks👍

[@RCexplained]

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

[@Andrew-hh3ol]

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

[@ISIAH_STL]

What weight oil would you recommend for a infraction in drag racing

[@relaxingmusic7301]

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 have two sets of front & rear differentials. Both were purchased online for the same RC truck. The front diff is identical to the rear diff on this vehicle. The front diff is identical with the rear diff in set #1 and are also identical in set #2, however each set come from a different manufacturer & the internal spider gears seem to differ slightly from one manufacturer to the other. The differentials from each manufacturer look identical on the outside, however when I open up the diffs to see the spider gears I notice one manufacturer's product has more teeth & smaller teeth than the other manufacturer's product which has larger teeth but less of them. I'm now stuck with the dilemma of deciding which set to use. How will the diffs containing spider gears with more yet smaller teeth perform compared to the diffs containing spider gears with less yet bigger teeth?

[@ubreakitirepairit3569]

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?

[@Abyssdiver]

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~

[@RCexplained]

If it's a 1/10 scale, I would run 5k in the rear.

@@RCexplained ok that's what I have. Its a sc6.1 and I run dirt oval with it. Not off road. Thanks for the reply 👍

Thanks for the video! I just got a losi rey raptor, im new to this! My rear diff sun gears were stripped just after two charges on 3s batteries. Truck is brand new; hobby shop i got it from said that its because i pin the accelerator when i just and land. I left the store thinking about it. I dont really jump the truck, just have been using in on my grass front yard and driveway. and the jumps have been from sidewalk to street. thats like 8 inches. which is nothing. just wanted your opinion. hobby shop wanted to charge me 60 an hour to fix it plus parts. So i just ordered parts from them and i am fixing it my self. I am just trying to figure out and understand why those diff gears were stripped so soon. Do you have any input? Thanks!!! when i opend the rear diff, the oil was thick and it was all over gears but definitely not full of it. grease looked metalic

[@RCexplained]

It does not sound like there is a reason that you should be having any diff trouble. Were the spider gears completely stripped or are they stripped in a specific spot?

[@cashmiller2999]

RCexplained the gears that were stripped are the sun gears. The two bigger ones in the end of the diff. The other 4 smaller ones look good. This is in the rear diff Thanks for the reply!

[@RCexplained]

@@cashmiller2999 I don't see a reason those gears would strip, especially given the fact that you don't have added stress from using throttle while landing a big jump.

What happens when you use million weight in the center, front and rear 10k in a typhon v4 6s?

[@RCexplained]

The power distribution front vs rear will be more balanced which means you will be able to get a significant amount of power to the rear wheels. 10k in the front will allow for more stability in the turns but will also allow more power to go to the wheel with less traction. Same idea with the rear however more power going to the wheel with no traction will keep you out of trouble. If it was heavier in the rear, the typhon could be more unstable under heavier acceleration. Diff oil is all about personal preference. I prefer to go light in the rear, heavy in the center and mid weight in the front.

[@Rob9947]

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?

[@RCexplained]

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.

hi there, what set up would u recommend on the arrma kraton 8s? and traxxas maxx 4s? thank you very much

[@RCexplained]

I've found that the stock settings perform quite well. More specifically to my driving style I usually go a bit heavier oil in the front and center diffs.

[@markcumming8849]

Very well explained, appreciated.

Hello i have Corally Kronos and i am interested for fluid in differentials because the car on 6s is brutal the car constantly rises i wont more power in front diferincial du you have any solution original fluid front 7500,centre 5000,rear3000 Thanks and regards from Slovenia

[@RCexplained]

Hi Herman, what do you mean that the "car constantly rises"?

[@hermanzarn8263]

@@RCexplained with throttle 70% or 80% on 6s it raises it to the rear wheels or even turns it over

[@RCexplained]

If you want to get more power to the front wheels vs rear wheels, go with a lighter weight in the center differential. If you want more power to the rear wheels go with a heavier weight fluid.

Hi bro..what is your recomended for diff oil 1/8 Nitto buggy using C Hub??...for front,center & rear..👍👍🙏🙏

[@RCexplained]

My recommendation based on my personal driving style for 1/8 or 1/10 scale RC cars is to use: 7-10k weight in the front differential. 10-15k weight in the center differential 5k weight in the rear differential

@@RCexplained oh i have one more question...the diff you recomneded is suitable or not with C Hub car or Pivot Hub car?..because someone said that if Pivot Hub car must using different diff oil setting from the C Hub car..they said that see Pivot Hub car is more aggresive & will oversteer when to take sharp corner..for C Hub car dont have any problem on corner but not aggresive like Pivot Hub car..can you explaind it to me...other people said Pivot Hub car must using heavy oil diff to control the oversteer problem..i also see also when the pro driver have problem overtseer with the Pivot Hun car..you can see the different if C Hub & Pivot Hub while on sharp corner then exit corner accelerate 🙏🙏🙏🙏

Hi Mustakim, I have never considered 2 different weighted oils for those different conditions.
