First, the model airplane is afraid of scratching. Just like the clothes we wear, even the best materials are afraid of scratching. When using the arch, please avoid sharp objects such as branches in the air and iron hooks on communication cables.

Second, if you need to move the model airplane, please lift it before moving it. If it is dragged on the ground for a long time, it is easy to wear.

Third, the opening ceremony is probably inseparable from shooting and fireworks.

Fourth, there is floating soil on the model airplane, which can be cleaned with tools such as brooms; If it is mud, you can clean it with a wet cloth.
