Using this model is easy. Just connect it to your DC - analog power source and watch it run. Since it's a delicate model, handle it with care to avoid any damage. When not in use, store it in the original box to protect it from dust and scratches. For maintenance, keep an eye on the wheel wear. Although it currently has minimal wear, over time, you might need to check and clean the wheels. The gearbox was recently serviced, but if you notice any unusual noise or issues with the running, it's a good idea to get it checked by a professional. Also, since it's a custom - painted model, avoid touching the paint directly to prevent any scratches or damage to the finish.
