Inside, you can see the motor controllers (red), the flight controller (green), the battery (blue), and the receiver (gray). I don't think I forgot any parts but I'm honestly not sure.
|Top is held on by a few screws|
|Section view. Wiring between motors/controllers will run through the hollow tube arms and up through the holes at the bottom center.|
|Printed a draft of the bottom on Rufus. After this I made a few modifications to avoid unnecessary support material.|
