Introduction

A hearts project of mine. We could never afford one of the higher priced RC-models back then. And all the cheap ones would break way to easy and were not worth the investment, so:

My mission is to deliver something high quality with a low-price tag with the option to customize!

Hardware

• High amount of printed parts

• Standard and easily accessible non-printed parts (hardwarestore)

Electronics

• 2x550, 21T, brushed motors (legacy fun)

• 2x5200 mAh LiPo batterie

• 2xRadiolink Cool 9030 ESC 

Design

• Rigid and robust through continous threaded rod

• Segmented modular frame (from front to back)

  • bumper

  • steering

  • suspension

  • camber modul

  • motor unit

  • ESC unit

  • battery and electronics housing

  • suspension

  • spoiler

• Vehicle technology taken into account

  • Ackermann steering (30°)

  • Toe in-/(rear) and out (front) (1.5°)

  • Caster (sperate modul) (9°)

  • Camber (increasing linearly throughout the suspension travel) (0°@25% and 5.3°@100%)

• Steeringknuckles and suspension printed

• High torque capable constant-velocity joints

• Ball or plain bearings on all moving parts

• Enclosed and active cooled motor and electronics housing

• Internal cable routing

• Weight and rebound adjustable suspension

• Triple limited slip Differential

  • Adjustable with an mixture of silicone grease and oil

• Weight distribution optimized design

  • symetrical

Requirements

• Knowledge of Printing with various materials and settings (ASA, PA)

• A little metalworking like cutting rods, tubing and drilling holes XD

Release Date

• When it’s done…

Most of the information on this page may are already out of date at the time of publication. A lot of testing is going on at the moment and this is an teaser to get some feedback about new ideas and how much the community likes it. So feel free to comment...

Development (problems and difficulties)

• Melting bevelgears -> alternative materials like PA

• open cv-joints -> no lubrication (binds dust and forms an abrasive paste) or protective sleeve (material, design)???

• liquid lubriaction of motorgearbox -> seal design on two plane faces?

• Batterycase for LiPos (6s NiMh battery are used at the moment) done!

• Shock absorber need dustwiper done!

• 3D-Printed tires -> TPU not viable -> hybrid tire with tpu core and bike tire outer layer

Changelog

• 23.04.2026: initial creation / teaser of version 2.0 / CVJ for printing (everything started with that)

  • CVJ-BOM:  6x6mm steelball, 6xM2x10 screw

• 26.04.2026: design and development status added

• 16.05.2026: complete remake of suspension linkage and steering. overall size reduced by 10%. New Design added in pictures.
