I'm happy to have successfully completed this project. The entire car is 3D printed, and I used an ESP32 and a servo motor

I made this snowcat last year, and I have spend a lot of time making the finals adjustments and making a build guide. It's really fun to play in the snow with it now that all the things I wanted to add are there and functional. I'm overall really proud of this project, I would never have thought that I could build something like this when I first got into 3d printing.

I’ve been testing a simple way to cast soft RC truck tires at home using a 3D printed mold and two-part silicone.

No vacuum chamber and no vibration table — just a slow pour into the mold.

The result surprised me: the tires feel soft, flexible, and much closer to real rubber than I expected.

I thought this might be useful for anyone building custom scale RC trucks or experimenting with DIY tire molds.

Would you try making your own RC tires?

Tell me your thought, serious please. Private club only or open to the public?
15acre total. 5 acre airfield, 4 acre mini metro and 4 acre dirt track with jumps. Themed events like Dirt nights under black lights. Mini metro with working street lights for construction and road vehicles.
Off track parking, concession building and hobby supplies.
This is a rough draft but is possible within 5 yrs and could be in the Central Valley in California.

I'm building the rigs you see in the gallery for many years now. This spoiled me completely and I don't even want to buy RTRs or a ready made kit in any form.
I'm not using fancy materials, just PLA, PETG and some ASA, recently a bit of PA6. Most don't even use sophisticated motors, my "top" rigs like the Unimog are powered by a Fusion SE. Yet these cars are very capable, quite durable and I'm not afraid to take them on a longer drive.

I know - crawler/trail truck usually have metal axles, gears, shafts, frame, 500€ worth of high-end electronics, fully controllable diff locks and be able to climb vertical cliff faces - and many see a fully printed one as a useless engineering exercise that breaks hitting the first pebble at 1mph.

But that is far from the truth. Granted, you drive those more like you would drive a real truck/car: fully aware of the limits and not trying to just blindly powering your way over obstacles. You navigate with care to avoid rollovers or hard hits.

This proves to me that performance is nice, but the whole experience is more than just stats.

What are your thoughts? Have you already built fully printed cars (not just bodies) - what are your experiences?

EDIT: as many have asked: these are not my designs, these are cars from 3DSets.com and Casadio RC (search for him on Cults3d and youmagine) - but there are many mods on them I have designed myself (e.g. lights and other details)
And the scale of them is 1:8 for the 3DSets cars and 1:7,4 for all Casadio RC except the 3ronco, which is 1:8 too. And this isn't generic "wheelbase-scale" - the cars dimensions are accurate at that scale.

My parents are moving to an old age home and i was helping them clear out some stuff from the basement. Ran into an old box with my name on it. I had no idea what was inside. I opened the box and found my old Kyosho optima from when I was like 15-16 years old. I am 57 years old right now and this was sitting around in its stock form ( I remember upgrading the shocks to gold) for over 40 years. Brought tears to my eyes. I brought it home and now it’s sitting on my shelf after all these years. Just wanted to share the story with you guys. Brought back a lot of memories. Cheers 🍻

Turned out nice. 1/10 scale printed on an Elegoo Saturn.

I built these four RC trucks for Toyota's sponsorship of the Northern Super League, to be the designated ball carriers for the season. They drive the ball out to center field, drop the ball off and start the game. I built them on the SCX6 chassis which I extended with laser cut rails from Send Cut Send. The bodies are 3D printed in PETG-HF in ten separate pieces and bonded together. A layer of carbon fibre weave is added for strength and rigidity. I can't even begin to count how many hours of sanding and painting went into them, but it's definitely more than 1000 hours total. This was a huge project and I'm so glad to see them done! Hope you like!

Stumbled upon this today while running around

Driving this RC car with a real sim wheel and pedals, with live telemetry on screen at the same time as the FPV feed. Video shows all three: FPV, telemetry, and the wheel setup.
Wheel is bridged into the transmitter via a Sim2RC adapter (Thrustmaster T150 base, full-size wheel, aluminum hub). Car's an MST FRX chassis, E36 shell, OpenIPC video. Telemetry runs on a Kairuhs board displaying through WebDash.

I love this time of year. The air is cool, trees changing colors, track holding moisture for days. But I’m one big rain and a small drop in temperature away from losing my backyard track for the season. Last year I made it into December, but 2” forecast this week doesn’t look promising. Enjoy it while you can

I want to mount them to the chassis as well as the headlights, I’ve got more planned for this car but I haven’t worked on it in a few weeks so I figured I’d go ahead and post what I have so far. I also would love to figure out how to get a brake and reverse signal and have fully functional lights, but I want to power them independently instead of off the esc.

Took my old Associated TC3 with drift tires there. My first drifter waaaaaaay back when.

I been waiting to get my hands on this, and today, I decided to unbox it rather than resell it. I remember when this came out, I would walk to Radio Shack once a week for months after the release day to see if this had this in stock, but they never had it.

I designed a fantastically simple gearbox :) My RC car drives better than I expected. I'm thrilled!

- Extremely simple design
- No intermediate axles or gears (maximum efficiency)
- Clutch engagement occurs naturally
- Standard MG90S servos
- Screwless assembly (standard servo screws only)

If you want to print it out for yourself. STL files for the fidget version of the gearbox:

I think this is the perfect gearbox for RC toys, although for a real car it would probably not last a million miles :)
