Define "Giant Scale" See edit...

The term "giant scale" gets thrown around a bit. For an airframe to be giant does it have to be a certain wing span or a percentage of the full scale airframe?

I'm working, very slowly, on a 20% Zlin 526 AS. It is an 83 inch wing.

Thank you!


OK, never mind... I just answered my own question with about 30 seconds of Googling Here is a cut and paste from the IMAA web site. There is more but this is the jest of it.

" This concept of "large" 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 replicas 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. "

Looks like my Zlin qualifies.
