Center diff , spur gear ratio and shims. If you punch it from a dead stop often it’s impossible to prevent the gears from chewing up .

[@RCKnockout]

Yeah the diffs that come stock aren’t very durable. These are better but I’m sure I could still strip these gears if I tried hard enough

[@gumby754]

@@RCKnockout I forgot to mention, some can prolly contest. The bulkheads if you screw them down to tight it can make a space 2-6mm’s where the meet in the center on the bottom side . I believe this could cause left to right movement with the diff as you drive maybe aluminum bulkheads would help with not spreading apart like the softer plastic .

[@RCKnockout]

@@gumby754 that’s true I don’t like the design with the screw holding the two bulkhead halves together

[@wyattuitermarkt5608]

Protip the first thing I do when I work on my rc cars is take off the tires it makes the car easier to move around and is best to just get them out of the way that’s just from my experiences tho so do whatever makes you happy I guess, lovin the content tho keep it up

[@RCKnockout]

Thanks for the tip. You’re probably right it would have been easier with the wheels and tires off. Thanks I’m glad you’re enjoying the content

[@HeadBassVTEC]

I run a "big block" 1406 castle motor and 3s most of the time in my mini and I am really not eating through diffs that much

[@RCKnockout]

That’s impressive…the stock diffs haven’t faired well for me

[@Todd_G_FPV]

I shimmed my rear stock diff and never had a problem again on 3s but I loosened my slipper a bit

i guess I am kind of off topic but does anybody know a good place to stream newly released movies online ?

[@arturoalfredo6165]

@Everett Joseph i watch on FlixZone. Just search on google for it :)

[@sebbbou5455]

you meant the slipper on the diff you loosened a bit? And you shimmed only the rear one? Thanks for any more info!

[@Todd_G_FPV]

@@sebbbou5455 slipper clutch is on the spur gear which is the gear next to the motor gear. And shimmed the rear diff only yes

[@PLASMA_2005]

Lol on 3s BIG BLOCK... they don't hold so good... tho my rear has been fine so far after replacement and bearings... tho my front is shot now... so getting one of these hr in the back stock in the front is what ima do lol

[@hotracinghelpdesk7243]

Excellent video friend, Great energy and honest chatter. I am always seeking good instructional videos for our customers and this one fits the bill. If you have any other HR videos, feel free to send me links. If they are helpful, I will likely send you viewers. Also, how about these parts? It's been some time, are they holding up?

[@RCKnockout]

Thank you! They are still holding up well! I do have install videos for the 32p gear conversion on the Slash 2wd as well as the Hot Racing Sway bar Kit on the Slash 2wd

[@earthling1984]

Do you run on 3S? My MERV is like 13 years old or so. Back when I first got it, I did replace the diffs once. After running a few runs on 3s and doing standing backflips and such. Since then I have basically just stuck to 2s. More than enough speed for the vehicle, and haven't had another diff break since.

[@RCKnockout]

Yeah I run 3s quite a bit of the time

[@Widflyinghigh]

MERV Owner. Appreciate this video, I was wondering about those myself, for the price and all. Really glad your trying those. Look forward to seeing how they work out. I have not had any diff problems, and run 3S, but starting to jump a bit more, so anticipating the need.

[@RCKnockout]

I still need to test them out. Hopefully they’ll be good considering how expensive they are 🤞

[@Todd_G_FPV]

Shim the stock one and if that gets destroyed try these lol

[@Todd_G_FPV]

Shimmed my stock one and its running strong on 3s

[@Widflyinghigh]

@@Todd_G_FPV . Let me just ask this. I see lots of old posts for old MERVS saying shim the diffs. I have disassembled the disc several times, adding different fluids for different results. I'm just not having any diff problems. I don't see the need to shim the diffs. Everything in there fits well. I even bought the shims, but don't really want to put in them in there since everything seems to be working fine. Why do I need to shim the diffs in 2021? What symptoms need fixed that the shims will fix currently on newer models with newer bell housing? Just asking because you mentioned it. Thanks.

[@Todd_G_FPV]

@@Widflyinghigh they will wear out faster without the shim but if its working fine don't mess with it lol I got my merv last year and it stripped running two nimh in series after a few runs. Got a new diff, shimmed it and now I run 3s on every run

[@mikegrigarauskas9136]

Its a great up grade just have to make sure to geta shim kit also or you'll just blow those also I have done it 2 times this will be the 3 hot racing dif I have to putting the front

[@RCKnockout]

Yeah it’s a must do upgrade for the 1/16 vxl e revo for sure

[@anarochrc986]

I just bought this for my erevo 1/16th

[@RCKnockout]

Nice! They’ve held up well for me

[@jordanrutherford1766]

Same problem here. Can strip a stock diff without even trying. I love my mini summit but hate the weak diffs.

[@RCKnockout]

Yeah I’ve had no issues since installing these….they’re expensive but they definitely seem to be holding up

[@jordanrutherford1766]

@@RCKnockout I will definitely have to pick some up I would love to worry less when moderately - light bashing. New to the channel and I can't wait to check out all the 1/10 Summit vids! I bought a second hand 1/10 Summit with a castle 2200kv motor run on 6S. Got huge 4.0 Rox Loxs.Its my first big rc and I love it. Subscribed!

[@RCKnockout]

@@jordanrutherford1766 should hold up with these diffs In it…..appreciate it man! Yeah the 1/10 summit is definitely a cool machine!!

[@DivineSadist]

Shimmed my diffs and theyve been great. Only running 2s. Considering replacing my rear with a helical, seems redundant and not cost effective to have one in the fron, hows the handling with the front helical installed? Im curious, but i feel like it would be worse.

[@RCKnockout]

I haven’t noticed any handling difference with the helical gears

[@donniemarks94]

After a hand full of runs with my lil revo I noticed the front diff slips a bit when turning the wheels by hand, easy runs to nothing crazy, no jumping or crashing

[@RCKnockout]

If it hasn’t stripped yet you might be able to shim it….I recommend the upgrade though…..the stock diffs are pretty weak

[@donniemarks94]

@@RCKnockout yea that’s exactly what I was thinking because it does work properly once it catches the gear lol

[@RCKnockout]

@@donniemarks94 yeah it’s probably just a very loose gear mesh

[@ekimusman2]

hey, man. what noticeable differences did you take away when running with the spiral diffs? worth it? how'd they run with the center diff?

[@RCKnockout]

They hold up well….I was constantly stripping the stock ones….they work well with the center diff too

[@PLASMA_2005]

When you fill the diffs your supposed to get rid of as much air as possible, I usually directly inject into slots etc. Or take a gear out to get underneath then put it back, I also find spinning the gears helps to move fluid underneath ALOT Also it is going to be hard to turn for the first bit but it's also a small shaft with little to hold too

[@RCKnockout]

Thanks for the advice 👍😉

[@gourobkundu2173]

The e revo 2.0 is my dream rc car. I really want to have it.

[@RCKnockout]

I haven’t heard a lot of buzz around it. From my understanding it’s not the most durable rig

[@gourobkundu2173]

@@RCKnockout Yes. Thats why i am in a dillema. Whether to get the maxx 4s or the e revo 2.0 Both are incredible cars, but i have a little bit of nostalgia with the revo. So there is an emotion. And rationally thinking, the maxx is a better option. Man, i am soo messed up and confused. Feel like getting both of them, but it will be highly out of budget. Anyways , both of them are pretty expensive.

[@Todd_G_FPV]

@@gourobkundu2173 its your money just get what you think looks better. E revo 2.0 is actually pretty durable once u fix the rear rod ends or just don't beat the living crap out of it and itll be fine lol

I like your video and I am thinking of upgading because of it but I dont see a follow up unless I missed it I have had to replace so many of those normal gears you said this thing should be indestruckdable did it live up to that???????????????????????? Thanks Mark

[@RCKnockout]

I haven’t had an update video yet but so far so good. It’s still going strong after 4-5 runs

[@fry9847]

I know this was a year ago so that hopefully means that you've tested them did they work well if so I will be putting them in my mini

[@RCKnockout]

Yeah they’re still holding up really well

[@RFHX2_6.0]

Has the diff fluid leaked out? That’s odd how the HR diff doesn’t have the recess to accommodate the larger O-rings to seal the diff fluid in.

[@RCKnockout]

No I don’t think it’s leaked out as of yet anyway

[@edwardredmond6476]

I have the same diffs and I put 20 million in my diffs and a slipper elementer and shims for the diff and all hardened transmission gears. Bullet proof and supper amazing to drive now you can just shim the stock diffs and you will be good for a long time. But I went over kill with my car . But shims are a must it should be the first thing you do out of the box . And servo. Lol the stock is junk 😂🤣

[@RCKnockout]

Yeah I found out pretty quick that the stock Servo was garbage lol 😂

[@alexcrowder1673]

My diffs obliterated themselves during my 1st run with my new motor even though i shimmed them. To be fair its a 2850kv 3670 sized can running 4s lol. Its meant for a car literally twice the length of the revo. So I got the hot racing diffs and hardened gears like 6 months ago, but i have been dreading installing them because i have the t bone racing chassis and its a pain in the butt to line it back up after taking it off lol. There are these little metal pieces that you basically have to ballance upright, all at the same time and then somehow stop them from tipping over while you install the skidplate. Its a nightmare lol. Its just so many extra steps and replacing the diffs is kind of a pain as it is lol. I basically have to disassemble the whole thing to get in there as it is.

[@sebbbou5455]

Hi great video! I just bought this diff and i’m wondering if i still to shim this diff like the stock ones??

It’s not a bad idea to at least try to…..mine was pretty tight and didn’t have much slop in it though

[@RCKnockout]

It is a nightmare….this chassis as well as the 1/10 revo and Summit chassis are the worst Traxxas chassis to work on

[@SpeedSyko]

I bought this car when they first came out. It was a insane tank on 3 s never broke it. I just bought one, broke a shaft in under 1 minute. I’m selling it. Now the diffs go? There cheeping out on quality big time. Sad.

@@SpeedSyko so you think the diffs in the original 1/16 erevo are better than the new erevos?

[@SpeedSyko]

@@RCKnockout it seemed to be, I remember ripping my first vxl on 3s hard. I never replaced an axle. Maybe it was bad luck? I’m modifying it so it won’t happen again. I had to do mip axles in my stampede 4x4. If you have any tricks, let me know. Thanks!

[@RCKnockout]

@@SpeedSyko actually I think I’ve only broken one driveshaft on my 1/16 e revo. It’s just the diffs that’s been the problem for me. I’m not really sure how to make a 1/16 Revo into an ultimate basher? I’m sure it’s possible though

You took the wrong screws off the shocks initially and took more apart than you needed to. Maybe it’s me coming from WW2 watch restoration but these screws are reasonably sized. If you want to see tiny work on a woman’s watch from the 1940s.
