A method for fabricating an IC board without a ring structure is provided. In another aspect, the beam includes a support surface defining first and second landing regions, which are in contact with and support a membrane. The distal end is located above the center of mass of the aircraft, when the lever is in the vertical position to establish a gravity pendulum, and forward of the center of drag of the aircraft, when the lever is in the horizontal position, to establish a drag pendulum.
