I guess all that stuff could be considered or just turn it in...

IMAA has unfortunately... or fortunately depending on how you look at it, been rendered obsolete...

They have been a great success, as the average modeler today is quite familiar with the larger scale model in one way or another.

No longer are 1/4 scale 80 incher models the "Big Plane" they once were. The "big bird" event now rarely require IMAA...and really, why should they?
