3.3 RULES

  1. Detailed rules for both the Nationals and the BOS are published separately.
  2. Rules will be based upon Section 7A of the FAI Sporting Code 
  3. These may be varied if local conditions necessitate this but a basic principle shall be that no additional rule or variation will be retroactive.
  4. The BOS rules should be relaxed in order to help in making these competitions less intimidating for pilots new to this level of competition.
