I didn't build it, Angel. I just got photos off the net.
Check out Atlantis Model and Toy Company's website. The old Aurora Invaders UFO is available. Wave makes a 1/48 Adamski-type Flying Saucer
It comes with clear domes so you can install LEDs. I have the 1/72 Haunebu German Flying Saucer. It's the same kit, parts and sizewise, as the Adamski kit, except for the clear domes. Another couple of cool flying saucer kits are the 1/35 Moebius 913 LIS Jupiter 2,
which is 18" in diameter, and the 1/72 Polar Lights812 Forbidden Planet C-57D Space Cruiser
This kit is 28" in diameter. The upper and lower domes are molded in clear styrene.
I have two Jupiter 2s with lighting kits and a C-57D which will receive the lighting treatment also. I bought a couple hundred feet of fiber optic filament in various diameters to use in illuminating the flashing panel lights in the J2 and C-57D.
