Sporting Code Section 4 contains the rules and regulations for FAI recognised activities in model aircraft and space models. These regulations are the responsibility of the FAI Aeromodelling Commission (CIAM) and complement the General Section which contains the rules and regulations common to all FAI activities.
Section 4 is split into volumes to ease downloading the regulations for specific activities. Volume ABR gives the General Rules for CIAM activities, competitions and records that are applicable for each activity. The specific volumes contain all CIAM documents for the activity concerned: Official classes, World Cup rules, provisional classes, guide for organisers and judges. The specific activities and related volumes are shown in the tables below.
