Boost Performance: Discover Why Locking Your RC Vehicle's Differential is a Must-Try!

[@seancook4317]

will locking my 2wd xl-5 stock rustler make it do wheelies? it kind of can now, but i have to reverse first and then it will , but would locked one do it without going backwards, i thought about getting the 272R transmission and maybe that would help better, i dunno anything about rc trucks right now (i like this channel because of that, and because it's fun and interesting to watch)

[@mprovedtuning]

swap in a $40 amazon esc/motor combo and it will.

[@Powerpickle68]

Before locking, try thicker fluid. Most differentials in ready to run rc cars have fluid that is too thin.

[@LassoKid7777]

Too thin or none at all

[@patriotcontainers4349]

I ended up buying the scorched lockers and havent had any issues yet that i know of. I kept my old diffs just incase i want to go with 20mil of ear plugs to try out. I noticed no more ballooning and my tires were lasting longer

[@RCexplained]

Sounds really good!

[@Turtlefry]

Thanks for the info. All of the TRX4 that i have, have transmitter diff lock control. The old and new Bronco and the Defender. Not sure about the Sports or High Trail version.

[@markcole6475]

4x4 off road crawlers are different animals than a basher…ya want all the wheels locked for better traction and unlock diffs for tighter turns..(if applicable) Bashers benefit from a locked center diff but unlocked drive axles for better turning .. Air control is benefitted with locked center diff also.

[@insomnia7337]

TRX4 Sport does not have the ability to switch. Always locked. Likes to flip over if you go too fast on a turn :)

[@shaenadunham9437]

The hightrail does have locking unlocked diffs . I. Actually trying to just bypass this and manually lock mine in and leave it. I keep burning out the micro servos. And just issues I don't Need or want to Deal with . Besides that I mainly crawl around areas where full lock is needed anyway. 10:48

[@ikariku]

Great video. Your edition has been improved!

[@RCexplained]

Glad you think so!

[@josephcaruana9165]

I increased the thickness of the oil especially the front butI was thinking, to try out the exb diffs because they are stronger but unfortunately the ratio is a bit low and I do not like to make the center prop shafts spin very fast!

[@josephcaruana9165]

Kindly, what do you think regarding drag racing with a 4wd car like a Limitless with a diff lock instead of the center diff and some prefer to use 2 or 4 million in the front diff and 2 or 1 million oil in the rear. Others lock the front and others lock both diffs. Drag cars are only used in straight line so one would like to try and take an advantage because although the car would be perfectly balanced it sometimes pulls to one side from the start line on full throttle! So they to prefer to have diffs locked so the power would not go to one side or spinning the other wheels with less load!

[@RCexplained]

The limitless doesn't have a center diff. As for front and rear, it's a personal preference. I'm not super comfortable with the both rear tires locked together but you may need this to extract maximum acceleration.

[@scottstalmack146]

What an awesome channel I've learned so much from these videos. So i have a spool center diff with a 50t (same as stock) that ive tried in my talion exb thays heavily built and i loved it but took it out cause I thought the spool would be more likely to break diff pins and cups when bashing. Is this true and also would silicon earplugs crammed in the center diff be better as it would still basically be locked but also have a dumping affect to absorb some impacts.

[@RCexplained]

Using a spool can indeed increase the likelihood of breaking parts when bashing. It doesn't mean you will but if the car gets in to a high stress load situation, this is where the potential to break stuff increases. Using earplugs in the diff can serve to dampen some of this load and may be a good balance between using a spool vs a differential. It's impossible to know if your driving style could subject components on your vehicle to breakage.

[@Hungrybird474]

I ve broken the plastic diff cup screws . They shear off if they become loose so it’s good to check and shim like everyone says . Luckily not the Kraton 6s yet but a hbx 16980sa thst gets a 3s battery and is too much power imo for the little guy

[@Hungrybird474]

What number for the center . I heard 200k ?

[@SkunkCity_RC]

I run 200k

[@P0110X]

you could buy two or three differentials, prepare each with different oil, maybe one with 100k, other with 200k and a last one with 500k and then compare results. There are also 1M and 2M, or also ear plugs

[@laserbeam1620]

I use 500k in my center diff rc cars. 1 million would probably be better though lol

[@FarmerFpv]

That is good and all for bashing and speed runs. For racing, you need to tune your diffs for every specific track. In racing you want to unload the front more to pull you around the turns. Also in high-bite terrain locked center diff can cause you to constantly do wheelies. Other than doing speed runs people overpower their bashers and never use all that power efficiently. For jumping at skate parks and huge off-road ramp booters I do like locked center diff. You only have so much room to build speed.

[@johnbravo7542]

Yeah,I agree with you👍

[@RCexplained]

Great points! There is no one size fits all. It's also very much a personal preference.

[@rexrcs]

Correct, all fastest awd cars in real life have center differentials… this advice isnt fully correct

[@murrijuana2842]

Wheelies? Hahaha, learn to drive... champ

[@chaoticadventure]

I prefer ear plugs in the center.

[@RCexplained]

Perfect!

[@LassoKid7777]

I packed my diffs with grease and it's never felt better , nice positive drive, otherwise it was unstable at high speeds on track obviously cause the wheels aren't spinning at the same speed, so grease those diffs!!!

[@xboxice2005]

i prefer to have oil filled than locked, if i want it near lock i use thick fluid :)

[@RCexplained]

Great point!

[@martins2657]

Performance is not all, when you have a technical track, you need adjusted oils in differentials according to. Nobody wants drifting tank on the track. Im ridding the Serpent SRX8e-Pro. Also on bash i put lighter oils into the Sledge.

[@Macgyver46]

Interesting, I race a TLR tuned typhon and put ear plugs in my center diff. Then again my local track dirt is way different then any track I've seen in videos. Very dusty loose material unless heavily watered. I can't keep on the track running pin tires, I have to run off road tires like badlands to consistently get around this track.

[@laserbeam1620]

You should be using ball diffs on a track either way.

[@murrijuana2842]

Hahahahahaha nope!!! Old out dated tech. Just like slippers... learn to drive instead of handicapping your car.

[@AsurasWrath164]

​@@murrijuana2842you have no clue! To this day balldiffs are better on a dirt track than gear diffs in a 2wdbuggy.

[@NUeB_RCFPV]

Less video effects would be more fun to watch. Thanks.

[@D.J_RC]

WRONG!

[@AsurasWrath164]

​@@D.J_RCno, he's right! Especially as most of the editing doesn't make sense whatsoever.

[@RazorRC]

I like your channel, but sorry -- locking your center diff is about the worst thing you can do for an off-road buggy.

[@furyianman5157]

Pretty sure it's an opinion. Not a fact. But thanks!

[@AsurasWrath164]

​@furyianman5157 what are you talking about? Locking your center diff in a buggy would only make sense if you use said vehicle for a complete unusual application. But for bashing around or running on a track it is indeed the worst thing you can do. 🤦‍♂️

[@budmansdragracingchannel2726]

​@AsurasWrath164 then why do so many people including racers do it?

[@EYESWIDEOPEN00]

Are you by chance taking it to the extreme from a simple choice of words perspective though? When you tell people that they need to find what oils and what works best for them and so on, the term itself is a percentage based term. Thicker oil/fluid, even if it's only a 10k increase, you are still indeed locking the differential up more. Racers have done the same type of videos to explain your steering input v traction in the rear so i wouldn't read into it too much. Traxxas sells 1 million weight, they even fill their centre diffs with it for offroad vehicles

[@RazorRC]

@@EYESWIDEOPEN00 locked means locked. It can’t move. If it can move some, it’s “limited slip”.
