A semi-realistic, fully functional tank model inspired by the T-90M platform. Built using hybrid materials and practical engineering, this project focuses on real mechanical behavior scaled down into a compact, intimidating form.
The T90M Functional Tank Model is designed to replicate core behaviors of a modern main battle tank while staying within the limits of DIY fabrication and accessible components.
This is not just a display model—it is a working system with mobility, turret control, and stabilization features.

| Aspect | Status |
|---|---|
| Mobility | Stable, torque-focused movement |
| Turning | Differential track steering |
| Stability | Cannon stabilizer (in testing) |
| Durability | Reinforced hybrid structure |
- No fixed scale standard (affects part compatibility)
- Speed limited due to high gear ratio (torque-focused setup)
- Stabilization system still experimental
- Track efficiency depends on alignment and tension
- Add suspension system for terrain handling
- Optimize track design and material durability
- Improve stabilization accuracy (possibly sensor-based)
- Integrate camera or FPV system
- Enhance turret realism (recoil system, smoother rotation)
- Base chassis completed
- Functional drive system
- Basic turret and cannon control
- Stabilizer refinement
- Structural reinforcement
- Visual detailing
