Using this model is straightforward. Just connect it to an appropriate analog DC power source and watch it run. Since it's a delicate model, handle it with care to avoid any damage. When storing, keep it in the original box and foam to protect it from dust and scratches. Regularly check the wheels for any signs of excessive wear and clean them gently if needed. The motor doesn't make much noise, but if you notice an increase in noise over time, it might be a sign that something needs attention. If you're shipping it back, follow the standard return process and make sure to pack it well to prevent damage during transit. And remember, if you're not satisfied, you can get a refund within 30 days.
