Multi-wheeled vehicles (more than 4 wheels)

Also I should add, the copy translation only uses a bool value, and I can’t really find a proper way to offset the wheels. I’d prefer to simply be able to copy only Z axis movement, but that does not seem to be an option in the copy bone node…
Any time I try with adding physics bodies to the extra wheels, the vehicle either barrels forward and intense speeds, or flies into the air… and I’m too much of a noob to know why or how to fix it, right now.
