Is anyone working on a possible design for a flyable model of the Falcon Heavy, successfully launched in February of 2018? Is it doable to yoke three body tubes together side-by-side and somehow have them peel off and return to the ground separately? Could a model consisting of three side-by-side tubes fly straight, or would one have to add fins of some kind to keep it straight? I've always wondered about using clear Plexiglass for fins, to minimize their appearance and maximize the illusion that they're not there. Musk's design is so unusual that I'm pretty pumped about the prospect of modeling it. Thanks!
