Thanks, this is the furthest I've gone down the rabbit hole with a foam board plane. It's been a good use of the cold weather.
I think they are still a thing, used them when I built balsa.

Mr SPEED!
I was wondering 😂😂😂Because I wanted to keep it scale and not extend the nose I printed the radial at 50% infill to get a balance weight of 160g

Wow. Nicely done!
I saw you mentioned Fusion 360, and it looks like you model in surfaces? I have been 3d modeling since the FPS game 'Unreal Tournament' came out with its map making program. I also worked in the machining industry as a mschinist and programmer with time in a lot of CADCAM software, but I haven't done much surface modeling. I really need to learn that in Fusion.
This was done in solids. Haven't had much success in flattening surfaces using fusion and meshmixer. I'm working on a Lockheed Vega that has a really simple fuselage and not getting good results.
Current work flow is: model in fusion (all in mm), import the left half of an oval section into meshmixer and flatten it, export as svg and open in inkscape and it's consistently small and needs to be scaled up by 133.33%. Just experimented with one section and it was good on the former at one end but small on the other. Frustrating.

Try this...
In Inkscape, make sure your units are set to mm (CTRL + SHIFT + D).
The scale should be set to 3.77953.
But why are you using Meshmixer to flatten? Are you just trying to generate the wireframe geometry at a cross-section of your model? If that is what you are doing, you can simply create a plane through the area of your model you want to create a cross-section of. Then create a sketch on that plane. In the sketch, use the PROJECT tool to create a sketch through the parts of the model where they contact that plane (select the entire model). Then you simply export that sketch as a dxf.
I'm trying to flatten a section of skin. I think @Mr Man may be winning me over to onshape. It has a native process that is straight forward. Here's his video (a picture is worth....)

Oh, I see. Duh.
For your scaling problem, have you tried DXF instead of SVG? With SVG, it is based on your resolution. DXF's are based on actual measurements.
Importing to Inkscape should ask you for the scaling method to use to import the file. If there is an option to get the scale from the file, try that. If not, manually set it to mm.

More than one way to skin a cat 😉
I've been digging around to learn about this process, because this is a pretty useful process I could see coming in handy for various projects, and I found there are ways you can do this in Fusion too. Blender is another program that can unwrap complex surfaces and create a flattened surfaces with its included "Paper Model" addon. But Blender is a really powerful program, with a LOT of tools. I have yet to sink my teeth into that monster of a program.
