- In this Wltoys K989 1/28 Rc drift project episode 9 we are going to upgrade the gear ratio... Explaining spur gears at 0:25 installing reduction gear at 3:18 Speed test at 6:42 Drift test at 7:00
By changing to a smaller drive shaft gear and a bigger spur gear to improve the top speeds of the drift car feeling like drifting in second gear or third gear without doing any mods keeping it simple
Making the Wltoys k989 drift easy around long corners and be really fast Rc car at a race track beating the Kyosho mini z easily
In the two sets of spur and reduction gears, you also get spare gears for the stock parts of the k989 that I recommend you buy now
Since we don't know how long Wltoys while keep on producing spare parts for this great 1/28 Rc drift car
Each set of gears cost only 3 dollars and if you don't want the spare parts and your only interested in upgrading the top speeds than you can buy just one set of spur gears and you get the smaller 27 teeth reduction gear inside the set
Making this a very cheap Wltoys k989 upgrade but also very good improvement without having to do any motor mods making it easy and keeping the possibility to change back to stock later if you want

You don't have Pay extra... it's still the same old price!
It just helps to pay the channel bills... Thank you for your support :D
Always looking forward to your videos, they are the best K989 resource on TH-cam. I have four K989's using your mods and tips. Keep up the work. Kudos
Thank you Tomas Mozer apriciate your comment 😃
Wow you have 4 k989 that's nice
Are they all drift cars or also for racing?
How To DIY Rc One drifter two racers and one for spares.
I think HTDRc would agree that Beavers Hobby is also a good channel to watch for this project.
of course, i like beavers hobby and recommend him to watch if your interested in drifting the k989 we have a lot of the same content but different style
I see that's smart idea luckily it comes with so many upgrade parts
even found metal arms and c hubs special made for the k989, not the mini Q
but very expensive for the size of course
you probably also visit a local racetrack if you have so many?
Great tutorial on changing the Spur and Reduction gear. Nice modification. Thanks for the video and Happy Drifting!
well thank you sir we do ower best and it's still not the end of the project we have more upgrade and mods coming it's such a fun car thx for the comment :D
Very nice work~!
Well done~!
First Like!!!
hahaha probably first view too :D:D:D
thanks :D
Hi, 4 days ago I purchased this fantastic K989 and it seems to me that in my car the sprockets are made of metal or am I wrong?
Thumbs up from me bud.. Enjoyed the video and this part of the upgrade. Definitely noticing drifting a little easier now. a great looking car as I am concerned.. Thanks for sharing
I'm not sure Faster is better but I'm gonna try this mod and also try the low speed mod .... see what work best for me .... Did you notice any temperature changes when installing the Bigger Motor pinion and smaller spur ? deff need these bags of gears .
the motor is always running warm no matter what gear you use and temprature stays very simmeler and its good to try them all and see what you prefer the most it defantly makes a big difference have a good weekend
How do I get the metal gear off the motor
Complimenti bel video tutorial 👌🏼 Quindi con questa modifica hai notato che va più veloce?
15T, 29T VS 19T, 27T
Which faster ?
Cheers ,Dave.
Another great installment in this series - Such a versatile car for modding so more 989 parts inbound :)
Get that body on the car - its naked!
well MrE I only pick Rc cars with lot's of spare parts and upgrade possibility's
we like to build test improve and test some more :D
lets be honest if you can't do any mods where is the fun right?
I hear that,brother!
Spectacular video.....
thank you E will i'm glad it entertains you but we got something better coming
soon you get to see some flying wing video's i'm sure you going to like those more :D
If it Flies, it has my attention...lol
Hi Guys. In my WLToys 979 box it had another packet with a longer differential gear which I will use to elongate the chassis but also a 27, 21,19, 15 size gear. Did anyone else get these?
yes MrE also got that extra package it means you have the new version from this year and you also have metal dog-bones the old version came with plastic and broke the first day
the extra gears you get with the car is what I'm using in this video
the 27T is for the drive shaft and fits good with the 19T spur gear mend for the motor
Very Very Very Very nice vedeo!!!
if you really want some top speed then this is the way to go and a 4wd drift car like this extra power but your throttle control becomes more sensitive
if you install the one-way diff and get more oversteer you like to have less top speed and a more linear throttle control that's why this upgrade is better for a race car than a drift car :D
So in the motor gears bag there are 3 for motors, 15T, 19T and 21T. Interesting... I thought there were 4 from 15, 17 (stock), 19 and 21.
No, it's 16t and not 15t plus a 19t and 21t with a 27t reduction gear all in one bag
the stock spur gear is 17T
I think I see 15 stamped on the gear. Anyway, the point is there are 4 but the 4th one isn't what I expect. This is actually better. Just buy this one bag and you get all possible gear ratio.
yep super cheap upgrade i used the 27T reduction gear and 19T spur gear
but i wonder if a stock 28t reduction gear works with the smallest 16T spur gear?
it's 16T of camera i used a magnifying glass to read it lol
Yep, stamp is hard too read.
You can adjust your gear mesh by moving the motor in and out. The holes for motor mount is relatively long. I've used 15T in my car without any mods. Now that I use 12T I had to widen the holes a bit.
cool you wend for maximum acceleration is that because of all the extra weight of the ESC and receiver or you just like to have maximum torque?
Hola perdona ... queria saber si existen actualmente esas piezas pero metalicas ? Me gustan tus videos
no metal is heavy is no good keep it lightweight is very important
Do u know why the driving tooth gear grinds by the diff :(
Fine tuning my gears have np
hello, how can i remove the diff? I loosend the 2 screwes bu the other 2 metal pins i cant.
i have a vid showing you how check my channel for diff rebuild
Awesome men
cool man!
thanks dude
Man I love this little thing! How much did it actually cost with all the mods?
so far 21 on the car and 25 on parts most parts cost only 3 dollar a piece is next to nothing
and the plastic is really strong nothing broke yet after driving like we stole it and jumping at the skate park it's a pretty good car except the diff spider gears are really small and worn out fast if you don't maintenance and fine tune of course but for drifting you lock the rear anyway and the front diff can be replaced with a metal one way diff but it's not an easy upgrade and we got some difficulties with it... coming up in next week
Ok so i want one to drift i know the 969 is for drift and 989 is for rally but will the 989 drift like the 969 out of box with a change of tires or will i need other parts i want 989 to drift and rally but if drift is better ill probly pic up 969 first and 989 later but if i can get just as good drift action ill get 989
you need tyres and lock the rear diff to drift
if you want it to drift perfect you need extra parts as shown in the k989 drift project series we made
@@HowToDIYRc ok thank you ill probly get 969 and summer get 989 and build to do better in the dirt
@@HowToDIYRc do you know if they make oil filld shocks for the cars and also will any part you put on the 989 fit the 969
i dident find oil shocks but all the upgrade parts fit on both cars under the body they are same :D
@@HowToDIYRc ok awsome thanks did you find any better shocks to make the 989 perform better in the dirt
Hello my friend! Do you know if the kyosho mini z and the wl toys share the same size drive shaft? I would like to replace the plastic planetary gears with metal ones. Thank you any info is very much appreciated.
I'm sorry I don't know if they fit sorry Sir
Thank you for such a fast reply. I have pulled up pics of both that I found and both seem to be very different. Your videos are very informative. Thank you for your time and patience
We always try to help where we can if possible
if you really want a full metal setup than the mini-Q is something interesting for you
got a metal one-way diff and metal locked diff for the rear and metal planetary gears coming with the locked rear diff the only problems is it don't fit on the Wltoys k989 only the one-way diff
Yes I've looked into the mini z quote a few times. I may just purchase one because by the time I'm done purchasing all the upgrades for the wl toys it will be just about the same expense. Kyosho is a great brand!
ya but also very expansive i'm thinking about buying a sinohobby mini Q
already have all the metal diff's hire
You are confusing the gear names and product information.
WLtoys part # K989-31 is the Reduction Gears (27 & 29 teeth).
WLtoys part # K989-32 is the.*MOTOR* gears (15, 17, 19 & 21 teeth)
Technically, both of these are "spur gears", since that's the KIND of gear (not the position)
Just use the manufacturer's names, and it makes it much easier to understand.
thx :D
