I've had it in multiple variations for a couple years. Now it's a Cab-Over (COE/flatnose) with 6 solid axles and 2 steer axles.
Previously, it was a long-nose with 4 solid axles, 2 sprung axles, and 2 steer axles, and before that, the steer axles were turned by an electric motor (replaced by physical steering wheel).
The drive ratio is 16 turns of the motor to 1 turn of the wheels. Steering ratio is about 3 turns lock to lock.
And By The Way, I'm 5'10".
In these pictures, I'd say it's about 30 pounds total. The chassis is fully boxed, with a support core going from the nose to the front of the electric drive motor (3 layers of supports).
