Evaluating the Layout

posted by Model Aviation Staff November 9, 2011 In our recent meeting we completely reevaluated how we should layout and categorize the AMA content and news we publish each month. We'll continue to include favorite sections such as "In The Air" and "AMA News," but you'll find those sections may have a slightly different look and include expanded content. We invite you to share your thoughts as we redesign your Model Aviation magazine.
