Upon opening the Twinstar scale helicopter, you will find the major fiberglass and clear component parts
and hardware bags.  Hardware is identified by the size of the fastener or part.  This is done for ease of
assembly.  Be careful when opening bags as not to lose any hardware, whenever possible, keep all screws
