This is my first MOC. Besides the gearbox, it´s my own design.
4 RC functions:
1. Drive (L-motor)
2. Steering (L-motor)
3. Cabin tilt (L-motor)
4. Sequential gearbox N+1+2+3 (Servo-motor)
The gearbox is a modified version of a gearbox constructed by DurianObried (only gearbox-not shift mechanism).
The shift mechanism is a modified version of Jaco4´s design.
It works very well and shifts gear fast.
Front and rear suspension, small turning radius and working steering wheel.

Here is a picture on the gearbox shift mechanism. To the left you can see the servomotor shifting the gearbox.
