zip Comments After Five Years of Bloop Does the Prandtl flying wing have a lower maximum speed than other designs? PaulS1950, To minimise the induced drag longer wing spans are desirable they have weaker tip vortices and thus a lower drag penalty. . The basic idea of limiting the wing loading is to limit the stall speed and thus the destructive energy involved in a forced landing. Can the Spiritual Weapon spell be used as cover? Handling and performance are very refined with responsive controls, which are through a single center column controlling throttle, ground and in-flight steering. c) 4 Birch CNC cut wooden ribs (used as end cap ribs on wing).
