Here’s the “Hobo” F-7A underframe’s rear end. The unit’s motor is mounted over the rear truck. The round housing down the center would hold the pair of batteries. To get her rolling, one need only flip the red switch protruding from the middle portion of the fuel tank area.
Looking at the underframe from the head, there’s no speculating the origin of the “Hobo” mechanics. JAPAN is stamped on the front section of the underframe. The same place that provided so much excellent quality brass over the years may also be credited with giving the hobby world this gem.
This is a close up view of the underside front truck. The truck sideframes are cast of a brittle plastic, not unlike bakelite pieces I’ve seen. I assume to insulate the model from pulling in any current from the rails and also to avoid any possible shorts, the wheels are made of rubber. The years have not been kind and this F-7A is no longer road-worthy, thanks to the deteriorating state of the wheelsets.
No rubber-band belts for the “Hobo” F-7A, as one can see this is a direct-drive mechanism. The motor housed above the rear truck includes a worm drive that extends down to the truck and makes contact with a cog on the axle. Similar to the front truck, the rear trucks also feature rubber wheels.
