There are again holes with spacing 30,5x30,5mm and 20x20mm. Under the stack, there is a space to place a small capacitor. The arms are cut from 5mm thick carbon. The camera is mounted in carbon sidewalls that also protect it. The frame weighs 121 grams, which is very good for a 7" drone. The frame is especially suitable for building an analog drone.
