Gunther sent in a new Excalibur render with some crazy textures. It might look like every other fighter at first, but there are some cool features on closer inspection. The model is well done and some of the original purple highlights are retained. Some kind of mystery material makes up the ship's skin, and it's topped off with some reflective fins and a wacky cockpit dome. It's certainly different!
Here's a render I made from my Excalibur version. Hope you like it!
