Using this model is easy. Just connect it to a compatible analog - DC power source, and it will start running smoothly. When handling the model, be gentle as it's heavy and fragile. To maintain it, keep it in a dry place away from direct sunlight to prevent any potential damage to the unpainted body. Regularly check the wheels for any debris, as the wheel wear is currently almost none and you want to keep it that way. If you need to replace any parts, you can use the spare parts that come with the model. And remember, if you're not satisfied with your purchase, you can return it within 30 days, but you'll be responsible for the return shipping costs unless the item arrives damaged.
