Default Booster Assembly 2

... trial fitting the fins and trailing edge flaps. The fins are made from a balsa laminate composed of two 3/32 inch thick sheets. The grain is offset just enough to resist splitting. This also helps to avoid flutter by increasing their torsional stiffness (not alot, but it helps). The trailing edge flaps will be fixed at the same angle as the Orbiter elevons, only down instead of up. Probably about 5-6 degrees.
