Default Define Giant Scale

Maybe it's my search skills..... I can't find a definition.

What defines "Giant Scale"?

Is it wing span, a percentage of scale, engine size etc.

I will be building a 20% scale Zlin 526 some time in the next year or so. Is this "Giant"?


Thanks
Ken

Probably not. 20% is only 1/5 scale or 1:5. I'd be willing to bet that giant scale is more like 30% (1/3 or 1:3).

Per IMAA: 80" w/s monoplane, 60" w/s biplane, or true 1/4 scale, (ie 25%), for prop planes. 140" combined w/s and length for jets. This definition was set about in the 70s or 80s, when 80" really was a "giant" airplane. kinda hard to call a 72" Extra a Giant, but it qualifys, because it's 1/4 scale.

A Stitts Sky Baby has a w/s of 12ft. which means a 36"w/s model is concidered true 1/4 scale and IMAA legal.

The Zlin is 83 inches, so I guess it is "Giant" by the definition.

Back in the early days of R/C, just about anything larger than a .60 size plane was considered a "giant" plane. But now days 80 or so inches is a very common size to see at the flying field. Like my old Great Planes Ryan STA is about 82 inches but its hard to get worked up about it's size when my flying buddy has his 40% Piper Cub parked next to it. I have a 96 inch Craft Air Butterfly with an O.S. 15 on it. Is that giant scale? ha, ha. All kidding aside, your Zlin is a very nice size, and you should fly it at the "big bird" events if you want to. Just remember, when planes get up around 80 inches or larger, the hardware, servos, and linkages should be given careful consideration as to their strength and ability to hold up to the increased loads involved.

The easist way to define GS is if it won't fit in your car and you need a trailer, thats Giant Scale. Dennis

I like that!!!

It may be a year before I even start on the Zlin. I am at the present collecting information for the build. Short kit is avaialbve fron Lazer Design, Plans from Air age, Cowl and Canopy from Traplet, and all the other fixins yet to be determined. Had some good info come from another member here just the other day, about 13 meg worth! I had the Sig Zlin many years ago and decided I wanted something other that the "die smash" Sig kit.

My goal is to have one scale airplane and one scale Helicopter........ along with my daily flyers

Dennis has it right, if you cant get a 80in. one piece wing in your 6ft. PU box you got a giant. Leroy

P.S. Thats why 40's and 60's are so popular.
