Abstract
A glider, comprising a tubular body open at each end and having a leading edge and a trailing edge, has a two-ring frame assembly disposed about the perimeter of the leading edge to provide body shape and rigidity. A two-ring frame assembly comprises a base ring and a clamping ring configured to matingly engage the base ring. The base ring is placed about the inner perimeter of the leading edge of the tubular body and the clamping ring is placeable about the outer perimeter of the leading edge of the tubular body to retain the tubular body between the base and the clamping ring when the rings are matingly engaged.
