The time has arrived when RC enthusiasts are equally stoked about private people releasing their 3D printable projects as established RC companies releasing their new products! Great work!
Chretze well not really
@@mojaverc1585 you're just not with it then :( lol sorry
Project like this for peeps actually can make this hobby ultra pleasant, because you don't need to search for parts and order and wait and spend tons of money just to get back on the road or bashing. You print and go again. Genius!
Brilliant!! I love that torque dampening shaft idea.
Absolutely wonderful
Inspiring ! I literally ordered my first 3d printer and the parts to try and make that rc car :p. A video of the assembly would be amazing if someone can film his ! Thanks so much for sharing your work !
Parts order from Banggood took so long I am still only part way through the build of a V3. Am already loving the improved axle and frame design on the V4.
I will persist with the V3 as my son can't wait to drive it. Looking forward to start a V4.
Thank you!
Hey man! it's looking really good! can't wait to get my printer up and running and do this. Keep up the good work!
Its beautiful. Respect for sticking to the same project for 4 versions and following it through this far - takes some persistence! Great bit of engineering really well done. I love it.
Thank you!
I'm waiting for the last version maybe one day I will build it! Nice job!
Thanks man, been waiting for a while for this release, you rock!
The flexible driveshaft idea is brilliant!
Thank you! I was so glad when I came up with the idea it's so much simpler than what I did before
Absolutely incredible, this video earned my subscription, and I can't believe how much time and effort you must have spent not only designing it, but also making the files available to others as well as creating clear, detailed instructions. This is truly a work of art, and I can't wait to see what you make in the future! Keep up the fantastic work!
Thank you so much! 😀
mine, too ;)
Just came across this video and subscribed. Incredible work! Really looking forward to seeing your future progress and this gives me one more reason to buy a 3D printer. 😁
Tremendous work!
Ok that's very cool . I've seen one 3d printed RC car on another channel but this is just WOW . Can't wait to see what you have lined up next .
Great Work Man! Keep up your awesome designs.
Loving the cars and keep it up 👍
Been waiting a year for this! Finally!
Amazing!
This is really cool! Try reducing the preload on the shocks to straighten out the neutral position of the arms when it is under its own weight. Right now they sit at a very steep angle
Very cool
Thanks friend!
from Thailand
Dude! Good work!
Just stumbled on your vids and thank god I did. Awesome projects man, subscribed and looking forward to future updates!!
Thank you! 😀
Very nice design man! Waiting for the next!!
Excelente.
Bellissimo progetto!!molto bravo!!
Getting better and better each time I see this project!
Thank you! I've got some bigger stuff in the pipe, stay tuned! 😀
I was printing the Tarmo 3 as the Tarmo 4 came out. But I already finished the third model and improve it. I was a little bit disappointed, the spars always breaks! 😭
(If you want you can watch my experience)
I can't wait to make the next version.
Looks very nice.👌
Sooo great! Can’t wait to print it :-)
this is the BEAST! OMG, best!
This inspires me very much.
You have taken this thing to a whole new level good job
Thank you 😁
Wow! You just won't believe the change you made on me. I have started to learn Fusion 360 . Thanks for the inspiration
😁 I'm glad you liked it! Share your designs to the subreddit if you make something I want to see it! 😀
Bro i love all your versions. Awesome work.
Thank you! 😀
YESSSSS FINALLY
So cool 👍😎👍
it turned out really cool ;)
Hello. Great construction and project documentation even better. I am very impressed with your enthusiasm and talent. I started construction a few days ago benefiting from the free time and the holiday period. Regards, live long and prosper :)
hey, that's a really nice constructed car model. Great design!
Thanks 😀
last parts are printing today... OO BOYYY
This is so cool. I'm working on some parts to make rc components fit to Lego. So this is very interesting to me
Nice! 😀 Post what you make to the subreddit so we can all see it!
@@EngineeringNS the car is almost finished. I am just waiting for the wheel hubs to do the first driving
Wow It is the first time I see your work.
Ould you please make a tatra truck with their unique driveline. You cound make it so it easy to make it 4x4 , 6x6 and 8x8. Thanks
Great work !
For my next project I will consider it! 😀
Great work. I can imagine how much time you put in. I decided to take this on. I am new in 3d printing. Your posted STL's have round pads which exceed my build plate. I am using a flashforge creator pro 2. How can I get rid of those round pads on the chassis? What CAD are you using?
Really cool design. With such awesome projects, it's a pity you don't post more often. Have you ever considered designing a 3D printed RC tank?
I know there are already many designs on Thingiverse...your iteration would be interesting to see.
This is so Awesome that makes me want to buy a 3D printer, so cool.
Trust me you wont regret it
SanraS Uzumaki ender 3 bro. Just got mine 3 days ago. It’s kickass
@@user-cx5no9oi2w how big is it?
♥Engineering Nonsense
Hey awesome job!!! I already started to print parts and I've seen your BOM of non printed component, but please share also the inner electronics you're running!!! :) That would be great to start from ground up! Astonishing design and performances!!!
Inner electronics? 🤔 There really isn't anything threre other than what is on the BOM--What do you mean?
@@EngineeringNS Having just looked at the non-printed BOM I cannot see any parts relating to the wireless control of the vehicle? Any information regarding how you control the Tarmo 4 would be really useful as I am just looking to start my own RC project! Thanks 😊
@@EngineeringNS I just meant some more info about the combo transmitter/receiver, but nevermind, I figure it out! Just excuse an RC newbie dumb question! XD
A torsion bar style torque damper in the main drive line? Awesome. Patent it before some unscrupulous RC Company steals it them sues you for using it (Hint: Traxxas)
Haha gotta have money in order to play the game. Let's hope the don't pull that crap. Have they done it before?
Are the shock towers also 3d printed??? Awesome build
have you consider designing a rock crawler vertion of this 3d printed cars? it will be rad!
Hey i really aprechiate your work! I build this car for the past few weeks and it works very good, but it has a bit of a hard time when its starts to drive than it needs 1 - 2 seconds till it start to drive.
Sorry if something is written wrong, but i am an 12 year old boy from germany.
Wow it's really amazing! Do you think it would be possible for you to integrate a Brushless inrunner motor in the next rendition? To my knowledge they seem to deliver the most performance in RC cars. 🤔
I haven't yet decided, I tried an in runner on early versions of Tarmo4, and the performance was disappointing, but that being said it wasn't a high end motor. I believe there are photos of it on my Instagram and a few videos.
Theoretically an outrunner should perform better, it's just the selection of larger outrunners is not as great.
aye man dont make annual updates, make em every month, this is really good
TOO MUCH PRESSURE
great video. It would be great to see the video assembly of this machine.
Do you use regular PLA?
Yup regular pla
Wtf? How do you not have more subs my man?
Thanks man i hope i can build one just as good as yours though this will be my first build.
Best of luck to you make sure to share your progress with me I want to see it!
@@EngineeringNS Thanks will do!
Hi
First I would like to thank you for your endless effort and persistance with building 3d printed cars.
I have just found out about tarmo3 and ordered some parts, so my question is - do you think the motor and esc from tarmo 3 could be used in tarmo 4 or it will be underpowered, didn't start printing yet so I'm on a turnpoint now - to go with tarmo3 or tarmo4
Thanks in advance
The ESC should work fine, the motor will be slightly underpowered. It is half the power of the new one. You can always build it and if it is underpowered just buy the new motor it should be aveilable for about the same price. You will need to build some sort of adaptor though since the motors do not mount in the same way.
Is this designed to allow a custom body to attach somewhere?
No, but I tried to make the wheelbase such that it can be more easily adapted to accept a body. You just need to design body mounts for it that's all.
I don't know if anyone has already told you that, but, in order to improve torsional stiffness to you axis you need to put a 45 degree helical design. In alternative you can make a pipe. The cross section you made isn't the right one for torsional stiffness. That will bring a big improvement if you don't want the axis to twist.
Lol it is supposed to twist that's the whole point. That's why I designed it that way. You are talking about the drive shaft, right? 🤔
That's my 'torque damper' it reduces torque spikes and stops parts from breaking. It's part of the design and it actually works really well.
@@EngineeringNS I Imagined it was for that but i wasn't sure
Nice design because you don't achieve the isteresys of material
wow you are awsome
can i use other tpu based filaments or they dont flex enough?
They flex too much. The cheetah is very hard. You can use other brands but they must also be very hard. I believe the spec is 95a shore hardness
@@EngineeringNS Did you use the same Traxxas diff gears for the back diff?
Back diff is picked uses no internal gears. Both rear wheels turn together.
Woow nice design. I will do one in the future. I see a lot of bouncing in the suspension. Considering your experience, is it due to the soft wheels? I am comparing with the previous version. Bye from Spain.
Possibly from the tires. I don't actually have much experience RC cars, so I can't be 100% sure.
Cool project, thx!!
Just started to print some of the parts.
Will it make sense to print tarmo 4 or will you release V5 soon?
i was also wondering that too (:
how would you compare the strenght of the diff bulkhead? Is the front stronger or the rear? I noticed that they differ in design
Any particular reason you use outrunner motors on these? I don't see those on RC cars too often.
What filament are you using for the body? I love the look of that.
Just regular PLA, Marble colored
Hi, I am designing something similar and I was wondering how you did the steering. like the part at the end of the two arms that hold the wheel on. I saw two bolts in the video but from that angle, it looked like the bolts would have to go through each other. I really can't wrap my head around how that would work. Plz, help.
Hi, what gear material do you use and how much backlash? I struggle to design long lasting gears for my trophy truck.
almost done with tarmo3 and I have two tarmo4 s going
First video for me but u won me as a subscriber. It is what I always wanted to design but never did as i know how much time it takes. Thumbs up
Is there any way I can help you with? I have an old HPI Savage S25, MT-2, and a few more and I have experience, thoughts and ideas to share with you if you wish.
Yes, please! 😀 I have shared thr CAD files and on the subreddit some people have already improved some parts that I am incorporating into the next version.
If you would like to, take a look at things and if you see something that needs to be improved, have a go at it!
Hi, firstly thnx for good project. I started to building tarmo4 but I need shock absorber size. Whats the size of the shock absorbers.
Check the BOM or the subreddit
This is awesome. Just found this. If you need some wheel/tires, I have a TON of decent 1/8 scale buggy and 1/8 scale truggy wheel/tire combos. I don't know what type of setup you prefer, but if it will help you move the project along, I'd be happy to donate some for you.
Thank you for the offer! I have found some wheels though. If you want to see the current state of version 5, check out my Instagram or the subreddit where I've posted photos of what it currently looks like 😁
only seeing the footage the tarmo3 actually looks way more stable in its motion and seems like it can go faster without the rear pulling out to the side 🤔
Part of that is the tires on tarmo4 make it less stable. But Tarmo4 is much faster and more fun to drive.
Has anyone else finished printing yet? I feel like I have been printing nonstop since it was released :) Let's see some updates from the community!
Check the subreddit 😁
can you also print this part
Differential Gear set Traxxas
5382X
?
Thinking about making a nice scale 2020 Defender body for this platform. Nobody has made an RC one yet
That would be cool. I want to see it if you make it
Very cool! Would you please consider making a video of how you designed and iterated on some key parts like the drive shafts and the torque dampener? Also please consider adding an alternative 3D model site other than Thingiverse it's basically unusable and could go down permanently any day now.
Yes I will be adding the project to a few other sites soon. I'm super unhappy with Thingiverse--Which is sad since it's the best site.
Where did you hear that it may go down from? 🤔
I will be making an instructable soon on how to assemble the car. It's difficult though since my time is so limited atm between school, senior design and work and family.
@@EngineeringNS Hey, its great to see this project. I have some RC parts such as a Mamba X ESC, 1406 castle motor and full size 2s lipo battery. Could I get it to fit in this build?
That's a good question! I really have no idea 😂. You can try opening the cad files (linked in general instructions) and see if your parts will fit with them by making simple standins
@@EngineeringNS Good idea, I should have thought of that I am an official Solidworks Associate, lol. Great design by the way, it will be interesting to see how the design holds out with these high end parts. I might have to reduce motor torque as for the car I usually have the motor in, the entire driveline had to be replaced with thick steel to handle the torque.
Wow, now I want to see how it turns out too! 😀 If you decide to do it, definitely make sure to post pictures to the subreddit' so I can see it✌️
Hello, could you tell me the measurements of the trolley in general?
Hey,im planning in making a similar car like yours,but instead of one motor,i'am plannig unsing 4 of then,one in which wheel. Which motor can i use?the one you used in your car is a little bit overkill
with this tires its looks like rock bouncer...
What shocks do you reccomend?
has anyone done a 4 motor rc car?
this is very cool, but a lot of parts to distribute the force mechanically
Marc Frank the handling would be crap and you would need extremely advanced technology to make it so it acts like it has diffs. Never mind how weak it would be with all the complicated design that would be necessary.
@@mojaverc1585 oh yes diffs are an interesting problem
i build drones, so i don't think the technology is that advanced ;)
and i think it'd actually be more durable, because there are no diffs to break and the space thats needed for the central turning rod thingy
can be used structurally
What i mean by advanced technology is how the esc’s would need to sense more amp draw and then give less power to the motor which is counter intuitive because usually if there is more amp draw from the motor the esc will just draw more amps from the battery. Anyway as you said you are a drone builder so it probably doesn’t seen to be too complicated for you. There are so many things to consider and standpoints and views that could be justified in one way or another that would hurt my brain in terms of how a 4 motor car would need to be designed and the pros and cons and so forth that I am going to end this here before we start to have discussions that get so in depth that it is useless to talk about unless the design is actually manifested.
Wow I just realised how long my and confusing my sentences were. Oops
I'm with Marc, someone should definitely do (probably has done it). It could be as simple scaling down certain motors when inputting steering. Would be quite ready to do with a flight controller.
My question is would you go for motors in the wheels themselves (would have lots of unsprung weight), or motors where the diffs currently are (would still have a shaft to the wheel which we were trying to get rid of)?
Why do you need elastic shaft ?
Do you know exact reason why old o
ones kept breaking?
It wasn't the shaft that was breaking, it was other parts. The shaft flexing reduces torque spikes in the system and stops other parts from breaking.
What did you print the model in? PLA OR ASA?
Also, I built your Tarmo3, but the end cups keep burning out, the axels are fine, any suggestions? Would the new ninja flex torq damper fix this issue on the T3?
I actually designed a remix for tarmo3 that uses the torque damper design from Tarmo4 for those who didn't want to build a whole new car. The car is still built with PLA. I never had the issues you are having--there are other people who have similar issues and I am still not sure what the cause is.
could your provide an assembly video
Do you know if ninjaflex filament will work instead of the ninjatek cheetah for the torque dampener?
Ninjaflex is too soft and will not work. Cheetah is very very hard
Thanks, I have some cheetah coming
You giving out those prints for free proves that great people still exists.
What software did you use to design the car?
I used a software called OnShape 😁 thanks
@@EngineeringNS can you use fusion 360 ??
If required, can I ask for your guidance since I am not yet eligible to apply for a related course at my age in my place, and I don't know if anyone I know can help🥺🥺🥺🥺🥺
I am sorry, but my time is quite limited. If you're trying to learn CAD, onshape is free and they also have free tutorials that show you how to do everything.
Looks great, any idea what the max speed is now?
It's hard to say. I want to say its in the mid 40's (mph) but I don't have any way to test so I dont know. It's theoretical speed given the KV of the motor and the gear ratio was in the 60's if I remember correctly--Of course there are many losses and much friction so that is not realistic.
@@EngineeringNS Strap your phone on with GPS speedometer app? There's a few that can log speed and plot it as a graph or save the max.
@@jotham123 I thought about doing that, but my phone is rather expensive lol
@@EngineeringNS I understand :)
@@EngineeringNS Maybe you could find one of those speed limit signs with the screen on it that tells you how fast you're going and drive past. Haha. Or find a nice state trooper with a radar gun...
Will you be making a v5? If so will it be anytime soon?
Yes, I am working on Tarmo5. Just made a post about it on Instagram, if you want to see photos
Time to take it to a skate park and send it to the moon!
2:58 As bayrakları
kardeşim doğduğun ülke başkası ile aynı diye as bayrakları dememelisin bence çünkü insan başka insanların başarılarıyla değil kendi başarıları ile övünmeli yoksa kendinden öncekilerin yaptığıyla övünürken yerinde sayarsın
You need to 3d print a vacuum for that floor.
Yes I do! haha that house is under construction so there is a lot of space and a lot of dust! Fun to drive in though since the car drifts with very little throttle. 😀
Assume all parts are printed perfect 1 time off, how much filament needed for tarmo4? And how many types of fillement needed?
One spool of PLA, and probably less than 250grams of 95A shore hardness tpu
очень круто!!!!!
I have a 6374 and 12s lipo lying around that I want to build an rc car around but I had big trouble finding parts. Can this platform handle the power?
I am guessing not 😂😂 that's over 1kw of power, no? 🤔 It would be interesting to see what mods need to be made to go from 3s to 12s and from a 680w motor to one with well over 1kw of power.
Fpv camera?
Hi, are there other motors that fit in the motor holder?
Yes but they are also outrunners. You can always design your own motor mount to fit any motor you want
*This is very dangerous...*
That thing would take over my whole life if I feel weak and want to do one...
Its too late for me brother. Run while you still can.
@@EngineeringNS LOL :D
is it fast?
Is there an estimate on how much filament it takes to print the entire thing?
I think 1 1kg spool of 1.75mm
