Rebel 787 C1 - 1:24 Quad-Motor Cyberbrick Racer

Four motors - 16.1 km/h.

The Rebel 787-C1 is a high-performance 1:24 scale indoor/outdoor micro racer designed for builders who want uncompromising mechanical performance from a CyberBrick build.

Inspired by the legendary four-rotor endurance race cars of the 1990s, it translates that iconic engineering into a synchronized quad-motor powertrain .

🏁 Why print this

- Lightning-Fast Single Color Print: A complete single-color layout prints in just around 7 hours . - A1 Mini Friendly: E verything fits comfortably on a single 180 × 180 mm build plate. - Pure Living Room Performance: With a measured top speed of 16.1 km/h , this isn't just a display model—it handles beautifully and is genuinely fun to drive indoors or on smooth outdoor surfaces. - An Accessible Tribute: One of the easiest and most accessible ways to own a fully functional RC version of this endurance racing legend. ----------------------------------------------------------

⏱️ Friction-Free Print, Quick Assembly (Under 30 Mins), video guided firmware flashing

Never set up RC electronics before? No stress. The step-by-step PDF guide holds your hand through the entire mechanical build, and the video tutorial walks you through step by step flashing the firmware and binding your controller. You'll comfortably go from a box of printed parts to a fully functional racer—zero guesswork required.

🤓 The Nerd Zone ( Engineering Highlights)

- Quad-Motor "4-Rotor" Power: Two synchronized core logic boards drive four independent rear motors, delivering explosive acceleration and a scale-speed experience worthy of its legendary inspiration. - True Monocoque Design: The body is the chassis. By engineering structural screw points directly into the body lines, the car sheds 25 grams of dead weight, resulting in a featherweight 225g (including the battery) . - True Mechanical Differential & Low-Friction Drivetrain: A custom-designed open differential, paired with low-friction POM gears and precision steel pins, minimizes drivetrain losses for smooth, efficient power delivery. - Pan-Car Style Rear Suspension: The rear motor pod is integrated into a flexible pan-car-style suspension that allows the drivetrain to articulate independently of the chassis. This helps all four tires stay planted over uneven surfaces, improving grip and stability at high speed. ------------------------------------------------------------------------------

❓ Frequently Asked Questions (FAQ)

Q: What extra hardware do I need if I already have the Cyberbrick Ultimate Hardware Kit ZK003?

A: In this case You only need two additional items to complete the build, direct links can be found in the BOM:

- 1x Power Splitter Cable (2-Pin XH2.54 Male to Dual XH2.54 Female) - 1x Micro Steel Bearings – EA004

Q: Which version of the CyberBrick Official Standard Remote should I print?

A: I strongly recommend printing the Lithium Battery Version Standard Remote of the official remote for the best stability and performance:

- If you already own the Cyberbrick Ultimate Hardware Kit ZK003: You already have the extra Li-ion battery included for the Remote! - If you are buying hardware now: A Li-ion Battery is listed in the BOM widget, this is optional. Keep it checked in for the best remote performance, or uncheck it to save ~ €4.59 if you plan to build the standard AAA remote.

- If you decide to not buy the optional Li-ion battery and build the AAA remote: If you experience unexpected remote shut-offs, simply plug a USB-C phone charger or power bank directly into the remote board while driving for a stable power supply. ------------------------------------------------------------------------------

Clean The Buildplate

Before print, clean the buildplate thoroughly by hot water and liquid soap (NOT IPA!!!) There are a lots of parts on a single buildplate in this model (especially the single color profile), and cleaning the plate can prevent possible print failures.
