RE: Maybe if I post this I'll be shamed into finishing it..
The inspiration for this model can in fact be traced in part to the Cobra, though they don't really look that much alike. I have the plans for the Cobra always within reach in the shop so I can go "hmmm, maybe I should build one or something like it". The Cobra is a hair smaller yet, but the fuselage could stand to be thinned down a bit. It was designed some time ago when micro gear was not so readily available and compact. A buddy built one for electric but it has some "issues" that so far have rendered it unflyable.
The wing cores for this model are actually stolen from an Estes Astro Blaster kit.. it's some modified SD something or other that seems pretty clean and works well enough. I used a section from the middle of each panel making the span 26" and took out the sweep.
One of those ~20" span Cobras on a honking 1cc would be a severe test of pilot skill and eyesight.
