Does anybody have an accurate CAD drawing of the P51 D profile that they are willing to share?

Geoff,

CAD? Are you looking for a "vector" file? Is a profile scale model your goal?

I do this stuff all the time, been drawing vector line art for various reasons. Mostly for laser cutting.

Here's the thing. Making an accurate drawing in CAD requires tracing an outline of a drawing that's scanned into the drawing program.

One must realize that the accuracy must be in the supplied drawing itself.

The example below was for a customer who wanted plans, or at least really close scale outlines and some detail, at 122" in span. No plans were available for this model.

However, he supplied great art with sharp lines which I could scan and do this drawing. Actually a photograph of the drawing on my monitor.

Sent out full size rolled paper drawings.

I see no difficulty with your request.

Charles, I like to use scale outlines—albeit different scales to get the right moments—on semi-scale stunters. I've been thinking about building a Mustang for some time and was inspired by one in the English RC magazine RCM&E which uses crutch construction and does not have flat sides.

Thanks Charles but if it has to be drawn afresh, I can do ity myself. It's a long term project for me so there is no rush and, given my interest in Reno racers, there are some very tempting aircraft that could be modelled. However, I plan to model this Australian-built Mustang that operates out of the RAAF museum at Point Cook in Victoria.
