The 2007 edition of volumes ABR and F7 of Section 4 of the FAI Sporting Code which were originally published on 22 December 2006 were missing a few updates which have now been added to the documents. The revised documents are now available for downloading on the website at http://www.fai.org/aeromodelling/documents/sc4 We recommend that those of you who already downloaded the documents before the release of the 'revision 1' versions get the updated files. We apologize for any inconvenience this is causing and thank you for your understanding.
