Description

Lotus 11 - Cyberbrick - 11 km/h of Pure Direct-Drive Racing

This small, fast, and intentionally simple RC car is inspired by the legendary race cars of the golden era of Formula 1. Clean lines, a low-profile silhouette, and uncompromising performance — reduced to what truly matters: speed.

🚀 Maximum Efficiency Through Direct Drive

Unlike many other models, this design completely eliminates 3D-printed gear reductions and transmission stages.
The motors transfer power directly to the wheels — with no power loss from gears.

The result:

⚡ Up to 11 km/h top speed
🔥 Extremely responsive acceleration
🧩 Fewer parts = less friction = more performance
🛠️ Simple assembly and high reliability

Thanks to this uncompromising direct-drive concept, this car is one of the fastest for its size — possibly even the fastest CyberBrick car on MakerWorld.

🎯 Focused on What Matters

This project stands for:

Minimalism
Performance
Lightweight construction
Easy maintenance

No unnecessary ballast. No complex gearbox. Just motor, wheels, and speed.

If you're looking for a compact, fast, and straightforward RC project that combines retro racing vibes with modern 3D printing technology, this model is for you. Super fast, super simple!

Improvement ideas and add-on suggestions are very welcome in the comments!
I’ll do my best to develop and implement your ideas during the next holidays.

All Maker's Supply parts required for the car are listed in the instructions.

Nice model, deserved a boost! Some minor issues with the steering rod, I uploaded my fix. The .json also has some issues. Also the size of the holes that the reciever is mounted to is to big for the screws. Maybe instead of the 2 screws the designer could make 4 pins to push the reciever onto. (drone flight controller style)

Thanks for the boosts! Your review means a lot to me. I will try to solve the problem with the oversized screw holes with your idea. Could you please briefly describe what problems you think the .json file has

Replying to @rutr4_ :

For me forward and reverse was mixed up which was strange, not sure if that´s a "me" problem. To fix it I changed in the cyberbrick software under Remote, then under Left stick, change motor 2 to positive and motor 1 to negative. Under Lotus11, under Angular Servo, change Speed to 70, Max Angle to 80 and offset to -1 (offset might be different for you). Realy like the model, is so fast :-)

@Snowboard_Pro

where can I find this model for the upgraded steering rod pls and thank you

@HaiDii

Try using printed bearings

@Snowboard_Pro

what file did you use?

I have uploaded the file for this wheel

@Snowboard_Pro

found it last night. Thank you!!!

Very cool little RC car. When I get another boost it is coming your way. I didn't have any of the bearings or O-rings and didn't want to wait for my next Bambu order, so I remixed the wheels to use just a screw hole for the front axle and added foaming TPU 65a tires with fuzzy skin. It has too much rolling resistance to get started on carpet without a push, but it zips right along on any hard surface. I had a little trouble with the front steering rod flexing too much at the gear so I reprinted the nose cone with the space below the steering rod filled in, so it couldn't flex away from the gear. That fixed the issue. Thanks for sharing the model.

@Iplaychess5

I am having the same issue with the steering. If you wouldn't mind I would really appreciate it if you could upload the updated nose cone file. I feel like giving up on this project but I want to make sure I tried every option! Thanks!

@dkjnk2009

Replying to @Iplaychess5 :

I uploaded it as a print profile, which should appear once the "verifying" process is complete.

Amazing model. With Cyberbrick, it doesnt get lighter and smaller then this. Also it is pretty fast. And being direct drive, it is a very nice cool factor :)

looks more like the lotus 22

First of all, thank you very much for the really great model. I reinforced the motor mount a bit so that the nubs for the circuit board don't break off so easily. I also modified the front a bit so that the toothed rack can run without friction. And I used a different remote control than the standard one: https://makerworld.com/en/models/1543267-cyberbrick-pistol-remote-controller#profileId-1619972. I would be happy to send you the .STL's and the .JSON file

This is going to be my first Cyberbrick project and if it turns out well, I will boost it twice.(It turned out well. 4/5)

@rutr4_

And how did it turn out?

Replying to @rutr4_ :

I just got the supplies and will be building it throughout this week.

@Verstappen175

so it's pretty good but the steering does this thing when I steer to much to the left and it gets of the gear

The designer has replied

@Verstappen175

so it doesn't center

@Verstappen175

mabey if the bar had more teeth?

@rutr4_

Check the available print profiles, there you will find an improved version of the steering rod by another user

@Swords30

what other parts are you using ?? Such as the motors and the components. i see the instructions and bill of material , but not all is listed. can you list the rest

The designer has replied

@rutr4_

I have added a parts list to the instructions Makerworld is reviewing the change and will likely approve it shortly

@Swords30

Replying to @rutr4_ :

please specific on which cyberbrick to order. I will be building this awesome kit and would like to make sure I order the right kit . thanks for the creation really awesome

@rutr4_

Replying to @Swords30 :

The parts list is now available. Please note, for example, that 9 PCS of screws are used from the 100 PCS AA050, and not 9x AA050 (100 PCS x 9 = 900 PCS). Have fun!
