jsc models

and how you gonna verify that the scale drawing you are working from is accurate?
hunh? hunh?
how ya?
hunh?

The A-series are based on doubling the surface of the paper, so going from A-4 to A-3 will lead to the lineair size increase of the square root of 2, so blowing up your model will make it 1.4142 larger, that's approximately 141%. Going from A-4 to A-2 will make twice as big.

thats close enough for me.i just do it anyways but wondered what scale of finished models would be.dont need the figures to be that accurate as im not designing

a 1/32 Herc?

Thats gonna be a big model.

lol its already done.just waiting engines and undercarriage to go on,i will scrounge a camera and post some shots when its finished.

yup fat albert ended up with a length of 36 inches and a wingspan of 45 inches.now i just need a bigger shed so i can give the coastguard and israeli hers the same treatment

But only because of the essential condition that the the aspect ratio (ratio of length to width) of the sheet is retained whilst doubling the surface area.

Yes, db-sa, the ratio between the long side and the short side is in the A-series always the square root of 2, so two A-4's put alongside their long sides will give an A-3 with sides showing the same aspect ration, sq root 2, thereby doubling the surface.

ok this is all getting too technical foe me as a mere builder.air dave gave me a close enough answer for my purposes

currently building
jsc uss iowa -at a3 size
schreiber 1;200 bremen
air daves fat albert hercules blown up to a3 size

They also have different scale models

yes i have a few of those models thanks
