Description
New, find the motorized flatbed with ramps to replace the tank

This project represents a considerable number of work hours, a boost is always motivating (and free)😊

🛠️ Project Overview
After several years of testing - and many failures - my model is finally ready
The initial objective was twofold
- Maximize the number of 3D Printed parts
- while maintaining a robust and reliable model for use
🔧 Design Evolution
First versions
The first drafts featured 3D Printed leaf springs.
Their performance was very satisfactory during initial outings, but these springs proved fragile: frequent breakages and deformations required regular replacements.
👉 For this reason, the project evolved towards a more durable 4-link suspension.
Transmission
The first models were equipped with locked differentials (corresponding axles are available on my MakerWorld page).
However, this configuration put significant strain on the mechanics, causing breakages and severely limiting the steering angle.
👉 The choice therefore fell on open differentials
- first, small-sized, adapted to thinner axles,
- then finally 1/10 standard differentials, offering a better compromise between robustness and reliability.
- The complete axles are available here
🚛 Design
The cabin is largely inspired by Russian Ural trucks, with a deliberately raw and functional aesthetic.
📦 Required Hardware (excluding 3D Printed parts)
Here is the list of components to provide in addition to the parts to be printed
- 1x Injora transfer case
- 1x Injora or Lesu type planetary gearbox
- 1x 540 - 21T motor or similar
- 1x ESC suitable for the motor (used here: Hobbywing 1080)
- 1x 2S or 3S battery
- 2x standard servos, 20 kg minimum
- 1x Y-cable for servo
- 8x8 axles (available here)
- 4 driveshafts or print these
- 8x 90mm shock absorbers
- M3 screws
8x 1.9" – Ø ~120 mm tires
The provided instructions are quite basic but should largely help in understanding the assembly
Subsequently, I will surely provide other modules for the rear besides the tank
