Yep, those are CCBS shinguards (from the Star Wars buildable figures, I think) on this Vic Viper by F@bz. Don't they look fabulous?
This is a really unusual color scheme and F@bz pulled it off beautifully. I'm in love with that trans-lime windscreen, the design of the front prongs, and all those lovely greebles around the engines and guns. Everywhere you look there are innovative part uses and techniques - for example, I love the way the tailfin uses some SNOT to fit right into the slope of the rear canopy; the choice of dark gray "log bricks" as exhaust ports; the lime-and-blue "racing stripe" on one of the prongs... Some well-chosen stickers from official sets complete the model. A fantastic build and one of my personal favorite NoVVember builds I've seen!
