I'm making this for a design project. I'm putting acrylic pieces on the top and bottom to hold my components, that's the reason that there isn't a bottom or lid. I have a version with the lid, but I would have to look through previous iterations. The drone uses A2212 Motors as well as a 6200 mAh 2S LiPo (Ovonic) battery. I'm using an ESP32 for wireless control of the drone.
