The IMAA appears to be in their death throws because it was the only SIG that excluded anyone that was not an IMAA member from their events. Clubs wisely dropped the IMAA requirement to fly at their Giant Scale events for financial reasons mostly. Then they seem to have eliminated the IMAA forum that use to be on the their web site. I guess things have reached a state where they no longer allow non-members to view minutes of their meetings to get some flavor of what they are doing, membership numbers, etc.
In a day when you can shake a giant scale plane out of the box and fly it the same week one has to wonder if the IMAA has any revelance in the modeling community.
