Hi, I bought your kit and I noticed that the ESC didn't have any connectors to connect to the motor or battery with. Do I have to solder on my own connectors, or is there a simpler way to do it?
@@blueechodragon99 Sure no prob. For battery connection I'd recommend XT60 (or whatever matches the battery you have). For the motor leads I'd recommend matching the 3.5mm bullet/banana plugs that are on the D3542 motor you got. Here are some amazon links for ya: www.amazon.com/dp/B07XKHJ5SK/ www.amazon.com/dp/B07VRZR5TL/
Really like your channel. Building Tarmo4 following your build guide as well. Do you have plans for sharing smaller scale 3D printed RC cars in the future as well? Or a boat maybe?
Hey, thanks for the positive note and I hope you're finding the Tarmo4 build fun! I definitely would like to do a boat and some minis at some point and a quadcopter and a plane and a tank and a robot dog... lol. I've already got the next few cars on the go though so it'll be a bit before I get to all that.
hi, I'm from Vietnam and i'm a fan of your channel. I'm planning to make your design - The tarmo 4. The problem is.... in Vietnam we don't have the differential gear Traxxas 5832x for front diff. So my question: is there any replacement for this?? I have used the 3d printing differential but it is easily broken. Hope u can help me with this!! thank you
MkUltra is more solid for sure but requires more non-3dprinted parts. The Tarmo4 is cool but there's definitely issues with drivetrain reliability when using a powerful battery.
hi , i am from india and i am a fan of your content , i am planing to make a simple 3d printed rc car , can you please make a video on "should you build the GAMMA - a printed in place rc car" , you will find the files and the video of that car on a channel named " under engineered"
Hey man you're gonna want at least a 20kg standard size metal gear servo for this model, not a little 9G micro. I'm not sure if the mount would fit a 2212 motor but from a minor amount of internet sleuthing a 2212 doesn't look like it would be a good fit. The design specs call for a D3542 so that's what I installed and is what I'd recommend. Are you trying to repurpose an old drone, if so I don't think this model would be your best bet for that.
I haven't had any issues with the axles at all printed in the normal orientation so I think those are fine. I found the bell housings snap regularly on my build so a 45 degree orientation should help that. I think the more important issue though was that the bell housings didn't fit super securely into the diff gear and if they aren't VERY secure they will wobble a tiny bit, cause too much stress, and then bust. I had more issues with the rear locked diff so I actually glued the rear bell housings into the rear diff gear to make 100% sure they were tight and I haven't had issues with them since even printed in normal orientation. I even tried the reinforced bell housings with screws in them that you can find on thingiverse but I still had issues with them busting until I made sure they were super secure.
If you want to ruin your free time: open RC trial truck. It's awesome but mine is 12 kg and the stock motor is to weak. But you can move little birches in the woods.
To build a 3-D printed vehicle, it needs to be unique or why bother. There is a whole RC vehicle world out there full of off the shelf stuff. I was interested in what thehardwareguy did because he uses a motor for each wheel. He also has a complex control board full of custom software. It isn't necessary to re-invent the wheel by designing parts that are already out there and proven. Your name suggests you print RC stuff. I thought if I went to your site, your kits would include all of the printed parts. Not everyone interested in alternatives to store bought RC vehicles has a 3-D printer.
Some good points. IMO one of the big benefits of 3D printed RC vehicles is that the replacement parts are almost free if you can print them yourself. Generally the plastics we use aren't as strong as the injection molded ones companies like Traxxas and Arrma sell so 3D models break much more easily. I could definitely sell a complete 3D printed vehicle but without the ability to fix it yourself I'm not sure that most people would be happy with it. However, designs and 3D plastics are getting better rapidly so this could change quickly.
@@kodak_jack No tanks yet but I did do a tractor not too long ago and a snowmobile and a humvee. Slowly branching out into other things. Will check out that tank, thanks for the suggestion!
Build kits for the Tarmo4 are now available on our store here: rcprinter.com/products/tarmo4-build-kits
I wish this came sooner.

It really is!

You could go with the locked diff front and back but it wouldn't turn as well.
Tarmo 4 or MK Ultra ? which one is more solid and more simple to build ? I think the problem is to find all parts in France. Thanks
MkUltra is more solid for sure but requires more non-3dprinted parts. The Tarmo4 is cool but there's definitely issues with drivetrain reliability when using a powerful battery.
@@rcprinter Oh ok, thanks you for you feedback, I'm French and it's complicated to know all in you're video. I will choose the MKULTRA model.
I've had one of these bad boys printed out for like half a year now, just haven't gotten around to actually building it
New month starts tomorrow and it's a weekend... as good a time as any to get cracking on it!
@@rcprinter true, true... I may do just that!

I'll check it out.
What if i dont use that traxxas front gear set ? or can i print that
I'd say the traxxas front gear is super important for this build. I'd recommend taking a look at the T5 tho, its much more robust.
Do you have some link for the bumpers? Thanks for your great video
Theres a list of great mods here: github.com/buldo/awesome-tarmo4
do u share the shock towers u made anywhere online?
Hi I didn't make the towers myself. I think I used the extended ones here: www.thingiverse.com/thing:4306573/files
original engine mount fits on 2212? is 9g servo compatible for steering?

Where did you get the high shock towers?
I think it's the ones in this designers mod files... www.thingiverse.com/thing:4306573/files
Do you print the bell housings at a 45o angle? (and Axles)
I haven't had any issues with the axles at all printed in the normal orientation so I think those are fine. I found the bell housings snap regularly on my build so a 45 degree orientation should help that. I think the more important issue though was that the bell housings didn't fit super securely into the diff gear and if they aren't VERY secure they will wobble a tiny bit, cause too much stress, and then bust.

@@rcprinter Do you get into other RC stuff that’s 3D printed. How about a 3D tank like the one on Thingiverse called NoTanks?
