- Опубликовано: 16 авг 2018
- Welcome back to Budget 1/28 Micro Touring Car project.
Stage 4 of modification: this is end of chapter 1 of this project where I complete everything essential to run this car at a good and steady pace.
In this episode I'm filling diffs and shocks with gear diff. grease.
You can use any of this thick grease, for example I use Kyosho:

![How to Use Mini-Z Body with WLtoys 1/28 [Budget Touring Car Stage 6]](http://i.ytimg.com/vi/-gCJEXXWBEo/mqdefault.jpg)
Great review of everything possible on the 1/27 and 1/28 cars maintenance and upgrades market. Keep it up my friend, this is not only useful for beginners, as well that it is for advanced rc-drivers. Somehow you put the dot on every “i“ each time you uploaded a new tutorial video. Really fine and excellent work, kind regards from the Netherlands.
Man your videos are so great! I bought it and have cleaned and sanded the differentials and packed them with grease and put grease in the shocks too. It makes a world of difference without all that rolling resistance! Another mod that I did to mine is to raise the height of the front body mount so the body doesn’t get caught on bumps. Keep up the amazing work!
1:13 I used normal ball bearing grease, the one that gets used on bikes. The car is more controllable and with the stage 1 mod the motor doesn't want to melt itself. Old videos but the quality it's still there and the mods are cheap and effective, stage 1 and 2 should be on the list of every wltoys mini car owner
glad i watch this i’m going try to grease my HBX 2188a shocks thanks a lot .
I think you just saved me the headache of buying this thing. Thanks
With this low price, you can expect low quality parts.
Seriously, get the Atomic AMZ. It's a much better car and you don't have to pull everything out and check it because you'll have to build it from kit.
Quality is much better, handling is much better, everything's better. ruclips.net/video/u7Jsw8IW-zY/видео.html
WLtoys is good as a car for learning and to get into hobby if you are on a really tight budget... at the beginning. The cost can spiral out of control pretty easily.
More, more, more i cant get enough from your contet i Like it so much nice Video!
Great videos man, thank you so much!
Your Video's have been great on so many micro cars I have the K989 and we run them at our local track all the time. The toe is fine on mine for carpet racing, but have recently gone through and rebuilt mine, I added better diffs, a brushless system and some other stuff. my question is I have been playing with some different Tire and Wheel combinations, and curious if there is a way to have adjustable camber so I could tune it for the different tires. I have tried some of the 3d printed kits out there and the problem is some are not very good. I am looking for a more precise way to do it. Thank you for any help you may be able to give me on this.
Rick
You can cut and drill the upper arms with 1.5mm drill bit then use M2 threaded rod to make them adjustable. However this will weaken the parts a lot which is fine on a drift car but for touring, I'm not so sure.
Great vidéo ; thank you :-)
Hi Beaver. Are the replacement diffs and shaft pinion replacement listed in your notes the same parts for the wltoys 284131? I have a 284131 and want to have spares on hand.
Yes, they are. All the parts are the same. K989, K989 and 284131 are the same car with different bodies.
@@BeaversHobby thanks Mr Beaver 😎
Pour la graisse , je mettrais bien de l'huile d'olive !!! :-)
I wonder if we can just build on an atomik front end to get better steering.
Yes, you can. Mount the bell crank on the top plate, play around a bit with the ball heads and you can make it fit.
So glad I found your channel before running my model to death immediately.thanks appreciate it alot.
How often do you have to replace the plastic gears? I looked and can't find an upgrade anywhere.
Btw love the videos keep it up!
The original gears lasted about 10 battery packs for me.
After I modded it with other plastic gear and replace the diff with Mini-Q/Mini-Z diff, it's still holding up to this day. Not that I play it very much but with different plastic than the original it's much more durable.
Mr Beaver,
Please help:
What Ball differential should I order for Wltoys 284131 drift truck that is good/best?
Ball diff is not really for drifting. Get front one way and rear locked www.aliexpress.com/item/1005001671065507.html or just front one way www.aliexpress.com/item/1005001670938865.html and glue the rear diff. You'll need long CVD for the one way too bit.ly/3m1i4bd .
Here's my video to mod this chassis for drifting (it's the same car). ruclips.net/video/j9pO35iaqfo/видео.html
great video i love the wl toys
In the previous video I saw that you lost a part...what is ur experience about the build quality so far..?
This old version has pretty bad parts quality and fitting. If you get one right now you'll get a better car with good ball caps so you won't have to fix those (which could lead to broken parts). Only the diffs need fixing or replacing. Here's the video of the new version. ruclips.net/video/D6VeUNGfVkg/видео.html
Are you running the shocks with or without the compressor spacer?
I only have spacer in the back and tool the front out. If the front is too soft then you can either file down the original spacer so the shock has less resistance but not too soft, or make your own custom spacer from plastic sheet.
Hi i can’t find any information on the range of kyosho 1000-30000 grease do you know if it can be used in 1/10 and 1/8 scale nitro diffs. Great vids.✌🏻
Yes, it can be used in 1/10 and 1/8. I think they made the grease for big cars, we just use it for small cars as well.
Hi there. There is absolutely no information about that type of kyosho grease on the interweb your’s is the only video thats based on the product. I have now ordered the kyosho ring gear grease and the kyosho 15000 grease for the front and centre diffs and i will use the red 5000 grease in the rear diff on my 1992 kyosho usa1 nitro crusher. Thank you
Do you think the aluminum bulkheads and kyosho ball differential will smooth out and fix the transmission?
Just the ball diffs will do. If the aluminium bulkhead is made incorrectly or had any imperfection it'll be very hard to fix.
Is it good to change to a metal diff for wltoys ?
No, its' not. After using it for a while it chew my gears to pieces so I'm back to plastic.
2m cst. got it.
Hi, what number grease do you use in the front and back for a 1:24 drift RC build? Thank you
Front: Kyosho diff. gear grease #15000
Rear: Kyosho diff. gear grease #30000
Hello Beaver, would it not be better to lock the front diff like on 1/10 touring car?
I think it's depends on driver's preference.
Those stock differentials are less expensive than the grease....you can’t imagine how much I would like to see somebody put honey in the differential and see how it works.
What do you people think? Could that work?
You can put any sticky grease in it, it'll work. Before this I used to mix my own stuff from things I find in my house.
Beaver's Hobby wow, thank you for responding! I have some other questions though: if I want to have this car as a budget touring car, is it better to use the mini z (the normal black ones you showed) differentials with longer CV drive shafts or the cheap adjustable banggood Wl toys ball differentials? Do I have to get other ball bearings for the differentials?
What shocks or springs are compatible? And what Offset would work well on a small track similar to yours?
I planned on getting the mini z rims and foam tires, I hope they have good grip?
I really hope you can give me some answers on those questions and that I haven’t asked something you already told us, because I want to buy the Wl toys K989 and tuning parts soon, as a winter project.
Greetings from Germany and have a good day!
@@hobbypyromane2.05 Find ball differential but somewhere else and not banggood. That one is pretty bad. I got it here. ruclips.net/video/5fvx6Uw8mSU/видео.html And I'm not terribly impressed with it.
I've been told the red one on aliexpress is good.
Shocks from JJRC Q35 is compatible but there's no difference. Just apply gear diff grease to the shaft like in this vid and adjust the clips on the shocks to change tension. If you want to change the spring then Mini-Z AWD DWS springs work (part number MDW100-01) However you'll have to add more clips to the shocks because the springs are shorter than original. There's a way to get better shocks. You need to change the ball heads to 4mm and use Atomic AMR long shocks. They hold the grease better than WLtoys'.
Wheel offset also depends on the body you use. What I run normally is 1.5mm offset narrow at the front and 0mm offset wide at the back. Good width, good tracking and turning circle. Foam tyres should be good but again, depends on your track surface.
The body I use is now Mini-Z Corvette ZR1. It doesn't need shock tower mod but it needs custom front lip. Which reminds me I have to make an video update on this project.
my k969 makes a beeping noise from the motor presumably, is this fixable?
Unfortunately no, the beeping/buzzing when driving is from the ESC and it's normal to brushed systems.
Thanks for the reply. Now I am less worried ;)
@@warmageddon6460 My pleasure.
Boa tarde. teria a composição em alumínio para a troca? se sim, qual site? O Mini Z as peças desgastam com facilidade como o WLtoys K989? obrigado.
Aluminium are only available for suspension arms and such which I don't recommend because they gives you more problem than solving it. So the ones I recommend are knuckle and shock tower.
Front knuckles bit.ly/2WXw5ih
Rear knuckles bit.ly/2L9D2pp
Shock towers bit.ly/2XvDdlt
As for the gear that wears out no, there's no metal upgrade for it.
Mini-Z gears are more durable than WLtoys. Actually Mini-Q is more durable than WLtoys too.
😎👍 Try tamiya anti wear grease best stuff ever!
Thanks. I'm using Tamiya white grease on centre pinions and gear boxes. I think it's standard grease. Gotta find one of this anti ware quick.
check out my videos linked below for anti wear grease up one racing makes a nice one and tamiyas is even thicker it works great in open diffs and makes them more like oil filled diffs and you can tune the diffs by how much you coat the gears and internal pins or parts also. also works great in friction shocks...Best 2 anti wear greases I have used all others stink and are not good I found. ruclips.net/video/ubxK7hFv9a4/видео.html ruclips.net/video/bLwvIQhQAQc/видео.html
Same effect, different brand. But it's still nice to know some other brands out there I can find if I move to other location. I use Kyosho because it's easy to find here where I live.
good video
Which diff should I upgrade more, does the front diff require an upgrade more or the rear. Thanks 🙏
They are equally important but it depends on what you want to do. If you want to drive around normally but want something reliable you can replace both diffs with standard Mini-Z gear differential then upgrade the CVD with "27mm" long CVD.
If you want to drift then you can lock the standard diffs and keep using them then upgrade the front to one way if you want.
As for full blown racing I highly recommend you upgrade both diffs to Mini-Z (or Mini-Z AWD compatible from Atomic or GL) ball differentials and upgrade the CVD with "27mm" long CVD.
@@BeaversHobby thanks 🙏 really enjoying the content too!
@@jsquire470 My pleasure.
can i make this car into drift car? and what upgrade do i have to make?
thank you
Absolutely! Instead of changing the tyres to grip tyres (from episode 3), you can use Mini-Z wheels bit.ly/2WSecRf with Mini-Z drift tyres bit.ly/2I3a74k. Then lock all the diffs and it can drift instantly.
If you want full drift setup, I have a video for it too. ruclips.net/video/zB3pUN9XiSw/видео.html
ps. This car has many versions of the same chassis from touring (K989), drift (K969), monster truck (P929), etc.
Where can I find that 8 tooth pinion gear and do you have any mod ideas for the wltoys 1/24 drivetrain thanks love the videos
I got it from Tamiya Mini 4WD motor pinion set and plastic gear set fro small car/robot like this. bit.ly/359tyVb
As for the 1/24 drivetrain, Just free it up and it'll be alright. No need to do anything drastic.
@@BeaversHobby thank you very much sir
@@kevinconnelly2300 My pleasure.
For plastic gears is there a house hold item that can be alternative for lube?
Teflon, PTFE or ceramic grease will do fine. I got it from a DIY shop. Check your local electronics or educational shops that sell stuff for Arduino & Raspberry Pi robot building parts.
@@BeaversHobby thanks
@@AngeloDenwillPetate My pleasure.
8 tooth pinion, what pitch though? Is it 8T 48pitch? Could you provide a link for the 8t brass pinion gear too please?
Thanks for th great videos!!!
It's 50 pitch. For centre shaft there's no metal upgrade but you can mod it out of Mini 4WD metal gear. www.1999.co.jp/eng/10117288
What's the reasoning for the different lengths of the shafts? And will they all work the same and fit?
Because one of the original diffs was broken and original parts are brittle so I upgraded it to Mini-Q differential (Mini-Z AWD diff, essentially) and because this car is wide chassis while the diff is for narrow chassis so I have to use the long shafts to make it work.
You can use long shafts with original diffs too.
Check out stage 1 video for more info about the chassis.
@@BeaversHobby awesome thanks dude, also could you help me with finding some cheap 11mm rims and tires I've been looking everywhere and can't find any want to upgrade from the stock 8.5mm

Great videos. I have rebuilt the stock diff and suspension, on my 989.its an improvement. I now want to up grade the diff.Does the mini q ball diff fit the wltoys 989? Or should I go with the one wltoys metal one from Bangood. The miniq is cheaper? Thanks
Mini-Q ball diff fits WLtoys but you need long swing shafts (CVD) because it's Mini-Z size, here's the tutorial. ruclips.net/video/BLAHvTAa6nM/видео.html
Mini-Q diff isn't cheaper but it performs better. It also depends on where you drive, if you are brutal with the throttle and rough running surface.
You can try WLtoys all metal ball diff however the quality is random. You might get one that works really well or doesn't work at all like this. ruclips.net/video/5fvx6Uw8mSU/видео.html
Wl toys has a upgraded ball diff on bang good part #1395101. Do you think the stock dog bones will work with this or have to order longer ones? They don't have a length listed. Thanks!
Looks like stock dog bones will work with ball diff.
@@BeaversHobby ok, thankyou
Is 1/28 parts is the same with 1/24 parts? It's hard to find 1/24 parts in internet.
No, as far as I know they are not the same. At least most of them aren't compatible. Which part are you looking for?
The differential for WL A242, mine was damaged, both front and rear so my car can't run right now. I also looking for the metal based differential so the durability is longer and stronger. Do you have link for the products? Or maybe the plastic one?
Here's the plastic diffs goo.gl/hdg8wd
As for metal upgrade I haven't seen any of it yet.
Thanks for the link, man. Can't wait to see your next video.
For the fat, I would use olive oil !!! :-)
Ummm... organic!
@@BeaversHobby ; it's bad ? :-/
@@filsdedieu100 I've accidentally spilled vegetable oil on my bicycle and it was squeaking ever since so just be careful with vegetable-based oil. If it works, it works.
@@BeaversHobby ; I don't know if it works. But I know that olive oil (Olea europaea var. Europaea) is also anti bacteria so it does not rot. But maybe it will harden too much over time . The easiest way is to put on a good grease as you advise :-)
@@filsdedieu100 Just a stuff that made for the application is always the best.
Luckily my diffs and gears are still holding out on my P929. Runs well even on 1/10th rc tracks :)
Very lucky! Mine didn't last that long though. P929 also handles very well outdoor.
What I found was the diff cups and gear loosened even with a tight screw. Had to superglue the gear to the diff outdrives to prevent slipping.
@@rccartips Basically you've locked it. Solid axle/spool works too so that should be fine.
No I did not lock the diff. I glued the diff gear to the diff drive cup as it was slipping there.
@@rccartips Ah, now I get it! Great job fixing that to have a working diff.
Hey dude is there any wltoys body on eBay like the bmw body?(I know they don’t sell I anymore)
Right now, no. Even Mini-Z BMW bodies are nowhere to be found.
However, you can find a plastic model or another toy with 98mm wheelbase and make body mounts with magnet.
Beaver's Hobby thanks so much but I found a lancer body on eBay and banggood

@@tomwright943 Nice! I got the Lamborghini and it is a bit longer than 98mm. I guess I should have got the Porsche instead
Nice videos, I would like to buy W989 but it might be too fast for indoor driving for me. What options there are to slow down this car, change gearing, limit transmitter throtle movement mechanically, is there something I could tweak witx transmitter electronics? is throtle made with potentiometer & ADC or something totally different? can I change to less speedy motor?
So how far should i go if i only want drive it outside?
Just fix the car like in stage 1 and 2 is enough to run. No need to change the tyres or fill the shocks. If you are talking about the transmission range it's about 50 metres.
