For over ten years Hugh Thomson has published marvelous posts in his blog about the historical aircraft. Just look there to see the P-51 Mustang, F6F Hellcat, F4F Wildcat and B-25 Mitchell CAD models and – what is sometimes even more important – compiled datasheets of their ordinates. The true, accurate geometrical data are usually dispersed and difficult to reconcile in the thousand sheets of the faded out, barely readable original blueprints. Hugh studied them all and is providing this information in the easy-to-use form. If you need such data on any of these aircraft – visit his page and choose any of these packages, or just make there a donation, to support his future projects!
Below I am enclosing some screenshots of his research work:
Note that Hugh is also providing complete sets of the original blueprints scans. This is much better option than buying them from the source that I previously recommended (plans.aero – in this post). The big advantage is that by sending an e-mail to Hugh you are not contacting an impersonal Internet portal. Here is a real mechanical engineer, a specialist, who worked with these scans and knows all “pros and cons” of each package. Before buying any of these aircraft blueprints you can ask Hugh about its details, blueprint quality, image resolution. Highly recommended!
