Using this model is quite straightforward. Just connect it to a DC power source using an analog controller to get it running. When handling the model, be gentle as it's a fragile item. Since it's brass, it might be a bit heavier than other models. For maintenance, keep it in a dry and clean place to prevent further tarnishing. If you notice any excessive noise from the motor or gearbox, it's a good idea to stop using it and check for any loose parts. When storing, keep it in its original box and foam to protect it from bumps and scratches. Remember, this model is rare and long out of production, so take good care of it.
