YASS! been waiting for this series so much, since im also going to do this conversion

[@BeaversHobby]

I'm also glad it's finally up and running. This car has been sitting in pieces for months.

[@dankforest]

I have an old Tamiya Fox (renamed NovaFox) its a rwd buggy 1:10. It has an awesome oldschool brushed motor(revolution losi) im thinking of coverting it to a drift car. Its really fun with drift tires. So i think if i add gyro and replace servo and all but engine it will glide. BUT it wont be original 1984. Should it do it or leave alone?

[@BeaversHobby]

That's a tough question. Personally I'd leave it be because it's a vintage Tamiya and I have a soft spot for that. Then it'll get something like 3Racing Sakura D5 for RWD drift.

[@cheddarcheese8945]

Haha ive been watching your channel the day or so binge watching video after video , good work man awesome to see mini rwd ,i just ordered one last week but im in nz and shipping takes a whole month haha buy then should have plan set also going to convert to 1/24 scale to suit rx-7 model i built

[@Trifle165]

SUN JAE LEE Hey man, do you have any stl files for making a RWD drift Mini z?

[@almightyalan8942]

Personally since it's small I would reduce Ackerman to hold angle longer at higher speeds, I repositioned the hole where the steering rods connect to the wheel hub, try to have positive toe into parallel toe at full lock. Just my opinion

[@BeaversHobby]

Thanks for the suggestion. I'll look in to that.

[@AllaboutTheWoodrows]

Dude your ideas or knowledge is on point

[@theghaniya]

Thanks bro very helping, im trying to convert mine. Specially on steering system

[@sontoshi25]

Hey man! Thanks again for this vid, I'm binge watching literally everyday and learning alot from you. Quick question though, do you know if upgrading to metal steering cups/knuckles is better than plastic? Because mine keeps on breaking, it's the 2nd time already in a month, and ordering each time I break the part is kind of frustrating. (I accidentally keep on breaking it when removing the link rods, I don't know a better/efficient way than converting to metal. What do you think?

[@BeaversHobby]

Yes, the knuckle is a good upgrade to improve the durability. However make sure the ball heads are OK and don't have thick collar otherwise they will get stuck and won't have full movement for the suspension. You might have to grind the underside of the ball heads down in that case.

[@HeySkipper]

Hi beav! I ordered 2 mini q ball diff for the WLTOYS k989. Do i need special cups or the atomic universal shafts to install them? Can you post a link of the items i will need to get the ball diff in? You have been so helpful with these cars:) thank you for sharing your knowledge.

[@BeaversHobby]

Yes, you'll need long swing shafts. Atomic's are constantly out of stock most of the time so I also give you the link for RC-Aurora www.miracle-mart.com/store/index.php?main_page=product_info&cPath=67_74_1029&products_id=13988 ppm-rcracing.com/products/Wide-Crooked-Angle-Universal-Shaft-for-Mini%252dZ-%286061-Black-x-4-Pcs-Long%29.html

[@gtrckt]

Hi Beaver, at 7:00 I saw your upper swing arm was modified. Do you think it's important to include the mod to increase caber for front wheel?

[@BeaversHobby]

Not really. Standard camber will do fine. This is carried over from my previous project.

[@gtrckt]

@@BeaversHobby I’m relieved that I don’t have to do this mod. But isn’t a lot of RWD cars (eg atomic DRZ) shows quite a bit of front wheel camber?

[@BeaversHobby]

@@gtrckt Yes, but it depends on chassis to chassis and driver's preference. Some of them just work with 0 camber. You can also use rounded POM tyres instead as well.

[@gtrckt]

[@loga_912]

Hey, is there any other mods to make more steering angle in the k989? I want to keep it 4wd but wanting more steering angle. I changed the ballhead position from the servo horn. Is there any other ways?

[@BeaversHobby]

Make monoshoock for more clearance. You can also move the steering ball on the knuckle forward.

[@jensv.791]

Hey beaver würde es was bringen auf der Hinterachse auch ein monoshock System zu installieren?

[@BeaversHobby]

I've seen people doing it. I guess it's for rolling effect but I don't know how effective it is for controlling the car. I do monoshock on the front so I can have more clearance for steering. The rear doesn't need that.

[@harryfp1494]

I had an idea last night for a third bearing system that would hold the stock cut driveshaft in a bearing cup that is screwed into stock motor sper plate

[@BeaversHobby]

2 bearings would do if the shaft is short enough. You only need the front and the back of the shaft and it got that already. I just cut my screw really long.

[@brianstevens2244]

Where can I get the servo horn. I have everything else, please help or point me in the right direction

[@BeaversHobby]

It's from afrc 5g servo or powerhd 5g. However the angle is not enough and in the end I made my own extension to a straight horn. Check out part 3 and 4 for more info.

[@BeaversHobby]

Sorry, I have no plan for 1/24 at the moment. I might change my mind later though once I run out things to do on 1/28.

[@justinaldrich692]

@@BeaversHobby I hear you, good point. Keep on having fun. Thanks again for sharing.

[@pinkfactory2667]

is it possible to increase the steering angle without doing all this, is it that just by cutting the part of the cell and moving the pivot point of the ball joints this could be enough?

[@BeaversHobby]

Unfortunately, no. Simply moving pivot point isn't enough for RWD drifting. Even this is still not enough and you can see in my 3rd update how to make enough steering angle. However you don't have to move the servo if you don't want, just make the horn long enough and it should be fine.

[@tomwright943]

Hi beaver😊👍, I am just wondering....... is there a particular reason that not many people seem to do the mono shock mod on the rear of these cars? Thank you

[@BeaversHobby]

I think because the wheels are not really independent to each other so the handling will be compromised. The main reason to do this is to move the shock away from steering.

[@tomwright943]

Ok thank you 😊👍

[@Funcentric]

Nice setup. What is the difference between an external gyro like the one you have vs one that’s built into the receiver? Any advantage of an external one? I have a fly sky FS-BS3 on the way and wondering if an external gyro would be better and if so, how.

[@BeaversHobby]

Separated gyro unit is usually more responsive and accurate than built-in. However I haven't tried the new stuffs yet and these are what I know based on my experience with old stuffs. New ones like FS-BS3 and RC4GS might work just as good already.

[@Funcentric]

@@BeaversHobby I see. Okay, thank you. I did some further research and found that the external gyro allows adjustability within the unit itself whereas the ones built into the receiver are controlled only by the transmitter.

[@BeaversHobby]

@@Funcentric Some expensive gyro can adjust endpoint independent to the transmitter too.

[@cityofplant]

Do I need to install gyro for rwd to work properly? My car just spin out without one.

[@BeaversHobby]

Yes, a gyro is necessary for RWD drift.

[@jab84r]

[@haydnholder7090]

How do how get the front to grip like that? No matter what more weight or less weight and steering input the car just goes straight, ive got a ton of angle and everything just can't get the front to grip

[@BeaversHobby]

If no matter what you do the front just won't grip then you'll have to check the tyres contact and possibly put M2 screw into the lower arm to adjust the ride height and in turn, tyre contact.

[@haydnholder7090]

@@BeaversHobby thanks Ill give it a try! The ride height in the front is pretty low would it help if i rased it, im running a concrete in the garage maybe the front of the chassis is dragging on the uneven surface 🤔

[@BeaversHobby]

@@haydnholder7090 It's really hard to run this car on a rough surface already so getting RWD drift to work is going to be difficult. Anyway, check the front contact is the main thing. You'll need it to have tyre contact when you turn. The ball cap on the steering could be too tight and it pulls the arm up too so check that as well.

[@haydnholder7090]

Mod the steering still make me confuse😂 can i use gyc 300 gyro??

[@BeaversHobby]

GYC300 probably works. You can try but I don't know how fast it responses. As for steering modification, there are 5 steps. Starting from 1. doing up the servo horn with 2 holes at the top. 2. Cut the back off front bulk head. 3. Mod the steering knuckle. 4. making monoshock. and 5. stick the gyro down.

[@dilabbila9225]

What brushless motor did u use in this project ? And Esc tnx !

[@BeaversHobby]

[@goingcrazy00]

Does this shock mod make it more able to fit mini z bodies? And you could get it a couple mm lower if you remove the nuts on the bottom on the ball head and cut the shaft of the ball head by 2mm.

[@BeaversHobby]

No, the monoshock actually makes the front higher at the bulkhead/gearbox area. To make the front lower to fit Mini-Z bodies is lowering the front shock tower like this one. kzbin.info/www/bejne/Y5ime3iOjbx1e9E

[@goingcrazy00]

@@BeaversHobby but then you can't get the steering angle because the shock is in the way right?

[@BeaversHobby]

@@goingcrazy00 If the wheels has a bit of offset like 1.5 it'll get enough steering to drift in AWD. Doing monoshock is for extreme steering angle in case you do CS mod at high ratio, eg. more than 2.0 (rear wheels spin 2 times while the front spin 1 time).

[@goingcrazy00]

@@BeaversHobby you still do the C's mod on RWD? Don't you remove the dif in front and remove the center shaft for RWD?

[@BeaversHobby]

@@goingcrazy00 The CS mod is only for AWD. I'm sorry I was confused from talking you you in the previous video with out of the box K969 and all. For RWD, yes, this shock configuration is one of the few ways you get enough steering. Otherwise it won't work. However it's even harder to fit a Mini-Z body. ps. I'm still waiting for Camaro ZL1 to come out though. That one should be great on WLtoys.

How does it drive compared to the atomic rwd

It's still far off. This one only slides without spinning. Too violent with the control and there's no way to recover unlike Atomic DRZ where I'm in control most of the time.

[@glowiever]

Isnt that too much toe out? Also looks like too rear-heavy though

[@BeaversHobby]

Yes, toe is too much because the linkages I use can't extend too far. I really have to do something about it. Rear heavy is pretty nice though. I saw a lot of people hanging the battery at the back but didn't think it'd help until I tried. It makes the car a bit lazy to go in to drift and slow to in transition. But it's more stable and won't spin as easily.
