Only the mod will be shipped. This is a lightweight mod for the ATK F1 ultimate / extreme. It's for those who want to make it as light as possible. In the photos, white is for the ultimate and black is for the extreme. When fixing the board and screws, it's better to hold the area near the screws on the part side firmly. When fixing the body and the bottom, try to get them to fit together well, and adjust the tightness of the screws. The support material has been removed, but please handle the fine details yourself. Due to improvements, the shape of the details may differ from the photos.
