The Semroc SLS Arcas is a scale model of the Atlantic Research Corporation ARCAS research sounding rocket. The real ARCAS rockets were 4.5" in diameter, so with it's 2.25" diameter main tube the Semroc ARCAS is exactly 1/2 the size of the real thing! Built from heavy-duty body tubing and laser-cut basswood fins, this model is built to fly on anything from D to H motors. Motor mount adapters to fly various size motors are included in the kit.
