ABSTRACT:
Aircraft components utilize flexible fluted extruded twin wall plastic sheet to form aileron hinges, horizontal stabilizers and elevators, vertical stabilizers and rudders, compound landing gear, struts, and control systems which are lighter in weight and lower in cost than previously available structures. The landing gear has damping characteristics superior to previous gear. The invention is particularly well suited to remotely controlled flying model aircraft.
