    Technically it is Vega, but close enough. I planked it with very thin strips of wood and call it Ye Olde Amish Rocket. It even has an outhouse for a launch lug.

    This one has two wraps of 7 oz glass and fiberglass fins. Should handle and 29mm thrown at it. Just needs a lot of filling and sanding. It will be a sleeper in stock paint. Anyone have unused Bertha dacals laying around? 0615181732.jpeg

    I haven't built it, but I think I did the exact same RockSim design.
