One of the classic late-1970s Centuri model rockets, the Excalibur 2 two-stage sport model, photographed a few moments before launch in northeast Switzerland on April 16, 1986. For this flight, the booster was powered by an Estes C6-0 motor while the upper stage used an Estes C6-7 motor. The rocket performed flawlessly, but windy conditions, combined with the comparatively high altitude achieved, caused much drift during the recovery phase. A second flight by the same rocket that day was thus made without the booster and with the lower power of an Estes B6-4 motor in the upper stage.
The Excalibur 2 was a development of Centuri's earlier, beautifully sleek Excalibur, a single-stage model rocket styled to look like the sounding rockets of the day. Excalibur 2 measured 724 mm in length and 23 mm in diameter. The kit came with a plastic nose cone and Centuri's own Pass-Port staging connector.
