If I was to build a 1/72 scale B-29 the scale works out to be 1" on the model=72" on the real thing if I am correct. Now, what about weight? It has to be calculated differently. If an empty B-29 is 70,140 pounds than by using this method, the model would be 974 pounds. (one pound of the kit = 72 pounds on the real thing) Kind of heavy to put on a shelf. Does anyone know how to scale weight? I dont think I am going to scale the weight but it is an interesting question I think.
If you can make a 1/72 B-29 tire weigh 7 lbs, i want to see pictures.
Well, what you do is scratch build every single part in a B-29 out of the same material as the original. Then, when you get done, weigh it and you’ll know how much the scale weight is [:p]
To answer your question, I have no idea. 974 pounds for a 1/72 scale plane sounds kind of heavy, but I guess it could be correct. 70,140 pounds is a whole lot of weight!
No it wouldn’t work out that way. There are a number of considerations that you would have to take into account that do not translate into an x,y,z scale issue.
Weights of material do not translate
it would probably take less than 1 lb of aluminum alloy to accurately construct 1/72nd scale b-29.
(to make a 7lb tire, cast it in lead)
