RADIO CONTROL PRECISION AEROBATICS RULE BOOK 2018 - 19 Forward The Radio Control Precision Aerobatics rulebook has been updated to reflect changes made to the rules by both FAI (found at www.fai.org/fai-documents) and the Precision Aerobatics Committee. This is the official document governing Precision Aerobatics in Canada. The intent to any set of rules is to have a pre-determined guideline by which you can attend an event and reasonably know what to expect. If the rules are such that they are unreasonable or unmanageable then there is a pre-determined path to change or update those rules to reflect what the group of persons who utilize them needs. The content of this rulebook is only as effective as the ability and dedication of its users to understand and apply its regulations. It is not perfect, but it should reflect the actual practice of Radio Control Model Aerobatics in Canada. Should you have any questions or suggestions to enhance the rules or the book, contact your local committee member or the Chairman. The FAI rule book has not been duplicated in this document. the FAI sporting code for F3 Aeromodelling can be downloaded here https://www.fai.org/page/ciam-code Page 2 Precision Aerobatics Rulebook
