Redesign the Head unit. As mentioned in my previous designs, I am surely not a fans of the default head modules of the Modio. So I try to make one myself. I get the concept of the head (Swallow.slt) from Birds. . When detached, it can transform into a light aircraft "The Swallow" . For the overall design, I aim to design a robot that let people feel it is light and fast. For the convenience of making, it was separated into three files. The body part is actually the "The Air Stepper" I designed, you may delete the two big "Fan" to conserve the material
