Downscaling The Centuri Hornet to a Card Stock Model Part 2

Downscale models are sometimes a compromise.
You work with all the information you have available and hope you capture the feel of the original and as close to scale as possible.

The original Centuri kit was 19.8" tall as listed in the catalog.
Current Estes specs say the Hornet re-issue is 19.25" tall.
Is the Estes model shorter overall or are they not including the overhanging engine mount and engine hook? That would add 1/2" to the length and closer to the Centuri height.
Since this is to be a miniature of the Centuri version, I'll go with the 19.8" height and subtract 1/2" for the engine mount overhang.


Here's a screen capture from the Centuri instructions.
I drew in a rectangular box that was .736 high, the outside diameter of the downscale BT-20.
The screen capture from the instructions was set over the box and the body tube in the drawing was enlarged to the size of the BT-20 rectangle.

Sometimes these exploded drawings aren't accurate or to scale of the finished kit. If you don't have the original kit,some guesswork is involved.
With what information I can get from the catalogs and instructions, it'll be real close.

The JimZ fin drawing show the full sized fin root length at 2.25"
Divide that by 1.8 and the downscale fin root length will be 1.25"
The available die-cut fin drawing was sized to the shorter 1.25" root edge.
