VZ Chassis SPEED HACK ⚡ Ultimate Upgrade (Cross Spear 02) | Part 2/3

In this episode, we dive straight into the heart of the VZ Chassis: the drivetrain. I replace the stock internals with high-efficiency, race-ready upgrades designed to reduce friction, improve power transfer, and deliver smoother, faster lap times.
You’ll see exactly which motor, gears, bearings, and shafts I use — plus practical tuning tips you can apply to your own Mini 4WD build, whether you’re racing Japan Cup style or just chasing max performance.
This is where the Cross Spear 02 starts to feel like a true premium competition machine.
