Just wondering if anyone out there remembers if the Viking Mark II (circa 1978 by Tom Williams of Craft) with the 12% semi-symmetrical airfoil had a wider speed range than the 11 1/2% flat-bottomed Mark I Viking? I want to build a Nostalgia kit but am hoping for something that has a wide speed range for those windy days and not suffer too much drag with ballest on board. Would the Dynaflite Bird of Time be a better candidate? Thanks in Advance, Skye Malcolm - Columbus, Ohio RCSE-List facilities provided by Model Airplane News.
