RE: Scale Propeller Availability
You have all the information you need along the bottom... except a decent vertical datum line, say through the hub center.
You have the horizontal reference lines/layers. You've already marked (roughly) each section with a pink pen.
These individual measurements are transposed over the plan view., one layer at a time.
The only reference point you have unfortunatly is the trailing edge... but that is a minor problem
Having said that, I can see that the airfoil section are non to accurate.
It's doable...Yet why? It's simpler the other way.
