Dusty: Inside "Dusty"

You can open up Dusty by removing the screws underneath.

The phillips head screws are deeply set so a long screwdriver is recommended.

Once you pull it apart you'll see the guts. (excuse the crappy photos)

The Top (Brains)

The Bottom (Empty Space)
As you can see there isn't all that much inside. The electronics don't take up much space. The majority of it is wiring connecting all the switches to the main board.

You'll note that the propeller is attached to the top part.

The bottom has lots of room for your custom equipment.
