Using this model is straightforward. Just connect it to a DC power source as it's an analog - DC only model. You'll find that the gears have been cleaned and lubed, so it runs well with great slow - speed control. When handling the model, be careful as it has some red staining from the foam and mild tarnish. Avoid rough handling to prevent any further damage. For maintenance, you can periodically check the gears to make sure they're still well - lubricated. If you notice an increase in the motor/gearbox noise, it might be a sign that it needs a bit more lube. Keep it in the original box and pick n' pluck foam when not in use to protect it from dust and scratches. And remember, if you're not satisfied with your purchase, you have a 30 - day no - questions - asked money back policy, though you'll be responsible for return shipping unless the item arrives damaged.
