I tend to agree that a 400 foot limit is coming at some point in the future, that being said what I think may happen will be an incident with a full scale that takes place over 400 feet and if the modeler is let off the hook because
they are a AMA member and someone else that is not a AMA member that does the same thing is hung out to dry I think then we will see a 400 foot limit on all UAS.
