This HBX 12891 DUNE THUNDER 1/12 scale electric desert truck / buggy was sent to me by rcmoment.com
Thank you very much!
In this video:
The HBX 12891 DUNE THUNDER 4WD sand buggy handles very well with its oil filled shocks. But it's just not fast enough for my liking. So I did what I always do in such situations: brushless conversion! It may be the first brushless 12891 in the world. The messy wiring will be tidied up in the next part. And the Arduino DIY Open Source receiver will be mounted, using a 3D printed mount, which will be designed in Autodesk Fusion 360.

YEAH !! Brushless conversion !! Since i waited for someone to do it
I‘m glad you like it. I think it‘s the first brushless conversion video about this buggy. Stay tuned for part 2. The receiver mount is already 3D printed.
TheDIYGuy999 yes it's first ever brushless conversion on this buggy
Very detailed, excellent video!
Thank you.
Thankyou thankyou. I follow your guide in purchasing things, n mr Frank in assembling things. Soooo freakin fast, my rear HBX 12812 flip over due to fast sudden brake. I run at 50-75% speed, noob here. Dumbo RC gives me 15% speed for my kids also to play. Very nice
You're welcome
Awesome job my friend, I may do this to my hbx dune thunder
Thanks. Yes, you should. This thing is just too slow in stock condition.
TheDIYGuy999 I agree I just done a speed test on mine the other day and it only clicked up 27kph on my gps speed reader. Video on my channel
Wow.. so fast and stable.. this brand good build..
Sure is
Fantastic UGRADE video again my freind. Keep up the Mods brother 👍😁👍
Thanks, man. Part 2 of this mod will follow soon.
Look forward to seeing your videos mate 👍😁👍
Awesome!
Thanks
The Haiboxing 12891 DUNE THUNDER has a very nice suspension with oil filled shocks. Unfortunately it's a bit slow. So in this video I will show you, how to do a brushless conversion. If you like this video, like, subscribe and turn on notifications, so you will not miss the upcoming part 2 of this video. See you!
TheDIYGuy999 I see there’s a racerstar 2440 motor with 6080kv, do you think the batteries will be okay getting the faster motor? Is there a reason you went with the 4600?
No, they will not. Also, the 6080kV motor does have less torque. So go for the 4600kV version.
TheDIYGuy999 awesome! Thanks for the info, I appreciate it
TheDIYGuy999 follow up! Does this ESC allow for a higher voltage? Say an 11.1v battery source? Or will it burn up? I have a similar car. It’s the hbx 12812 or the redact KT12. All the same chassis.
Nice upgraded
Thanks
thanks for the video
i got the HBX Dune Thunder and after a short wile it stop going. the perment red lite started to flash
every once in a wile it become permenent again but only for a second
do you have an advice for me? thank u
Hi! Is the original remote still good after the upgrade? Or I would need a new one? THANKS! Great tutorial, I will definately do the conversion with my son!
No, you need a new one
Wow! That’s a fast Dune Thunder. Barely recognize it when it’s running that fast :-)
😂, netx time I should use 4k. What is your 4k camera? The speed is reasonable, but still not crazy fast.
TheDIYGuy999 Yeah the speed and acceleration looks very good. Fast but still controllable. I just use my phone for 4K :-) I only use it for small and simple one-takes. In edited videos I use 1080 60 fps.
The original servo worked with the new esc? And about the original transmitter and receiver?
No, you have to replace these components with standard RC cmponents
i have to ask you, did you shift the gears and use the second gear in the video?
This buggy does not have a 2 speed transmission. The version you mean is the THRUSTER, which looks very similar.
Hello thanks for the video. Did the spur gear can handle the power of the brushless motor? Thanks for your reply
You're welcome. Yes, I never had an issue with the gears
Ok. Thanks for your quick response. You are still using the plastic now.
I watched again this vid bcz i just get this truck ! Is this truck very durable with this brushless system in ?
I never had an issue so far. Everything is very durable.
@@TheDIYGuy999 damn, i got some hbx models, and damn i looooove this brand so much !
I saw a comment that had a link to original JST connectors to 3 wire for using original lights but can not find it anymore.. can you help?
See: www.banggood.com/search/dupont.html?p=NZ29024828314201605E
my apologies sir I was thinking of the 12889 thruster. with that in mind why did you buy this one and not the 12889 thruster?
No problem. I did not buy it, it was sent to me by rcmoment.com for review. I have to say, I prefer this version with its 4 wheel independent suspension. You can find a discount coupon in the description.
oh if i were gonna buy one it would be the 12889, but i am not gonna buy one i have way to many projects going on right now if you go to my channel you will see what i am working on. as soon as i get a good camera to do my videos i will continue with my project.
I have a Racestar 2445 5400kv and 25a esc laying around. Do you think this would work in this?
It should work but may destroy your gears
Will I need the open source hardware if so where can I get it from u don’t mention it in the links
I tink I have mentioned in the comments, that you can use any other standard 2.4GHz remote. If you want to build your own, you can find the software and the pcb files on my github
Super Video. Ich brauche mal deine Hilfe,unzwar wollte ich wissen ob dein ESC das mit macht und ob es doll heiß/warm wird? Ich habe die gleiche Kombi verbaut und mein ESC wird warm. Ist das normal? Wäre super wenn du mir helfen könntest :-)
Danke. Ein bisschen warm wird er schon, das ist normal. Der Motor wird auch warm, alles funktioniert aber wie es soll.
Super danke für die Antwort :-) Ich war mit halt unsicher ob das normal ist. Weil man sagt ja eigentlich das der Motor nicht mehr Ampere zieher darf als das ESC gibt? Stimmt das so? Weil den 2440 Motor gibts ja mit 6080 Kv und der zieht ja 47 Ampere. Das macht doch das 35 A ESC nicht lange mit oder?
Add pipo for more. Speed
It's possible to change just the motor?
No, if you want it faster, you have to use a brushless motor / ESC. A brushless motor has more power in the same can size.
Nice en usefull video 😄
I,m a newbie to the RC world Just ordert de car a week ago and yesterday i realised i need to have the 2440 and the 35A esc to 😈 zo ordert that yesterday also ordert the Servo don,t know why but you also put IT in so i think you had your reasons.
So no i,m thinking what spareparts would be usefull
Because when something breaks IT takes 2-4 weeks to get it Here
(Netherlands)
The car comes ready to run, but with brushed motor, so it's not the fastest. If you want to do a brushless conversion, you also need a 2.4GHz transmitter and receiver.
I have not ordered any spare parts so far. Everything is still in one piece. You can find the spare parts list here: www.banggood.com/search/hbx-12891.html?p=NZ29024828314201605E
The dogbones, hubs, differentials and gears could make sense to have on stock.
Thanks for the info! Why does the original receiver/transmitter doesn't work with the brushless??
Maby because the transmitter is in the esc of the brushed motor?
Does IT matters howmany channels? Just a noob here 😁 en any advise for a easy installing transmitter receiver whit the Wright functions?
Is this upgrade parts will work with HBX 12889?
I don't have this buggy, so I'm not 100% sure. But it looks like the motor and the servo are the same size.
Nice!
Thanks. Stay tuned for part 2 of this conversion!
Yeah shure
How about a drifting video with drift assist module?
As I said: this buggy handles very well with its oil filled shocks and it's 4WD. So a stability control system is not even required. But I may try it anyway. BTW: part 2 will be available in a couple of minutes!
Your videos are great! Which ever car is your favorite?
Thanks. I like everything, that‘s fast and handling well. For example the WLtoys 12428 is reasonable in stock condition. Or this one, it only was a bit underpowered. You can always find discount coupons in my review videos.
TheDIYGuy999 you have another cars (jlb, a959) which one is the best in your opinion?
In general I prefer bigger cars, 1/12 scale upwards. They just handle better and can be used for trail runs. But they are more expensive to maintain. The JLB for example is great fun to drive but it just eats gears. I hope that this issue was solved with the last modifcation (see video)
TheDIYGuy999 I like the architecture of this car. The balance is perfect I think. The motor and most weights (batteries) are well balanced. I am wondering if it is possible how to create the solution for 1 battery instead of 2. Ideally to put the most weights (batteries) so lowest possible to the ground (centre of gravity). Maybe using 3d print to put the battery under the car?
Using 1 big battery instead of 2 18650 cells is pretty much impossible in this car, because you would destroy the good balance, if you mount it on the top of the chassis. And below the chassis is no room left. The stock 18650 cells are working fine with the 35A Racerstar brushless ESC. You can also buy high discharge 18650 cells, which are suitable for this car. The link is in the description. And yes, I will use a 3D printed part in episode 2 of this video. Stay tuned.
does this car use the same spur/reduction gear as a959?
No, it is entirely different. Spare parts: www.banggood.com/search/12891.html?p=NZ29024828314201605E
TheDIYGuy999 I see but if you only need the spur you have to buy whole package. m.banggood.com/HBX-12891-Parts-112-Spur-gearPinion-Gear-Motor-GuardSteering-Bushings-12602R-p-1182330.html?rmmds=search so I was wondering is the spur of a959 will fit to hbx
Ziemlich schnell
40kmh vlt?
Ich schätze 50km/h. Im Originalzustand läuft er 35.
TheDIYGuy999 ok
First. First like too.
Congratulations! And thanks for the like.
