Does "Giant Scale" start by % or by a minimum wingspan?

Define Giant Scale please. Minimum wingspan or minimum % of scale size? See avatar at left. He's a midget in that plane. He's about 2% too small.

Re: Does "Giant Scale" start by % or by a minimum wingspan?

According to the IMAA:
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.

Thanks SleepyC, You are going to piss off my wife though. She's not going to like hearing that my 22.5% Yak 54 is not Giant Scale ! For everybody watching this 72"=22.43% of 26'9" wingspan full sizer.

You should have picked an 72" Edge or Extra instead of a 72" Yak. The single place Edge and Extra have a full scale span of just over 24' so you'd be 25% with those models.

Pretty sure no one would doubt a six foot monoplane as a quarter scale. Even if it ain't.

Back when I got started anything six foot and up was large or "giant" .

Sleepy Stated the facts, but my 1/4 scale Giles was 73" wingspan and I beleive it was IMAA legal 25%

Depends on the full scale plane.

A full scale Giles is a lot smaller than a full scale Yak.

Same with an Ultimate.
