Purpose
    The International Miniature Aircraft Association, Inc. (IMAA) is formed for the purpose of fostering and advancing the operation of large scale radio controlled model aircraft in a setting where informality and safety of operations prevail. Additionally, it is formed to create an atmosphere where pleasure, recreation, fellowship, and co-mingling can be fostered and found to exist amongst individuals enjoying the sport of building and flying large scale radio controlled model aircraft.

Who are We?

    Although IMAA is a standalone association, we are also the Academy of Model Aeronautics' (AMA) largest special interest group *. AMA is the world's largest sport aviation organization, representing a membership of almost 155,000 from every walk of life, income level and age group. AMA is a self-supporting, non-profit organization whose purpose is to promote development of model aviation as a recognized sport and worthwhile recreation activity.

    * Note: The IMAA was made a SIG (Special Interest Group) of the AMA in October, 1983.

What is Large or Giant Scale?

    The concept of large or giant scale is generally considered to apply to radio controlled model aircraft with minimum wingspans of eighty (80) inches for monoplanes and sixty (60) inches for multi-wing aircraft. Ducted Fan and Turbine aircraft with one hundred forty (140) inches combined length and width, measured from wing tip to wing tip at the widest point perpendicular to the fuselage and added to the length of the fuselage, excluding any protrusions. Autogyros with 50 inches for a single rotor, 80 inches for a dual rotor. Quarter (1/4) scale replica's or larger with proper documentation (minimum 3 view drawing of an actual person carrying aircraft) which do not fit the size requirements will be permitted. However, the concept does not encompass radio controlled model aircraft so large as to have the potential of carrying a human being.
