It is unreasonable IMO for the AMA or anyone else to think just because
you are a AMA member you cant fly certain types of models when not
at a AMA chartered site. IMO I dont think the AMA cares what you do
as long as you dont file a claim with them if you arent supposed to.

As far as them being dragged into a suit seems like it would be a easy
case to beat if they could show the AMA member was operating outside
the safety code especially if the member admitted to such.
