Don,
The first result of a Google search for "2018 FAI F1D rules" is a link to a
PDF copy of the FAI free flight rule book. Links can change and I don't
think the AMA should be responsible for keeping that information updated,
especially when it's so incredibly easy to find the rules on the FAI
website.
Regards,
Jake
