Griff,
Well yes, yes they do! And to further prove it here's some more.
The front nacelle lights pass through shaved down "lenses" shown earlier which then sit behind clear domes. Now the rear lights shine through cut down domes which are multifaceted and create a very nice scattered light effect. I like the visual interest as compared to "bare LEDs" and also this way not only does the light get further "effects" but you never see the LEDs themselves.
The model will sit upon a stereo plug which will allow more than just a straight power feed. This way I can hide a micro switch upon the model itslef to control the plasma weapon and the base will hold switches for interior lighting and nacelles as well as making the thrusters controllable.
The tubing has hole cut in it to peg the stereo plug to help it from ever pulling out of the tubing which can happen even when epoxied in place. The outer styrene was chosen since paint adheres better though there will be a metal tube within that for further strength.
The plugin will sit angled within the hull so that the display will allow viewing of the prominent bird on the bottom while it can also swivel or just be popped off the stand/pole so that you can still fly it about the room when the mood strikes! And with me, that's quite often.
