It didn’t look like a helicopter, though it did have those eight rotors. It was built of black foam, with a bumper of some other black material around its edge, and two rows of four holes, in which the rotors were installed. It stood on four slanted wire legs now, about six inches above the table. Its four batteries, currently charging at a wall socket, slotted into each of the corners, equalizing weight. It had a slender, streamlined black plastic fuselage underneath, housing the camera and electronics.
