Meet SMARC2 (Screwless Modular Remote Controlled Car), the awesome offspring of the SMARS Project! This design is all about keeping things simple and hassle-free. Picture this: the chassis is one single print model, including the steering system and all the other parts just snap into place effortlessly.
I've made SMARC2 with a focus on easy assembly and minimal fuss. By using components I already had and only buying the essentials, I've kept costs down. Sure, it might not have the highest performance compared to other models out there, but here's the thing: it won't break the bank or have you drowning in a list of parts longer than your arm.
In less time than it takes to make a cup of coffee, you can have SMARC2 up and running, ready to zip around your home with a grin-inducing joy! Who needs complications when you can have fun and simplicity rolled into one awesome ride?

Tips:
For the best result, some parts should be soldered but If you don’t have a soldering iron, you can just wrap the wire 6-8 times on the contacts and block it with a shrink tube.
The battery wires have some dedicated path inside the chassis, don’t solder both ends of the battery contacts before mounting them otherwise it will not be possible to route the cable in the optimal way
By bypassing the ESC, and connecting directly the JST connectors is possible to make the car go forward without any electronics control, so it will work like a “Let's & Go
“ Car
If the project gets enough interest I will further develop this branch of the SMAR system, future upgrades include:
Aesthetic:
body kit
Tail and front bumpers
New rims design
Functional
Custom motor with optimal gear ratio
Quick swap battery holder
Rims compatible with "some Danish construction blocks" tires (more grip)
Wifi control
And more according to your suggestions!
All further upgrades will be included in this purchase, I am trying to apply a reverse model compared to the SMARS robot due to high copyright infringement.
Hope you like the design and if you have any questions, feel free to ask :)
