This June I started working on a new (fourth) edition of my book about aircraft computer models. Actually, I am finishing its first volume (“Preparations”). It describes how to prepare accurate reference drawings of a historical airplane, on the example of the P-40. Below you can see two of its pages (as they appear my screen):
Comparing to the third edition, I altered here the proposed workflow, using Inkscape as my basic tool. I also wrote more about eventual errors, which you can find in typical scale plans. In the appendices I included a section about the original P-40 blueprints, which is based on the posts from this blog. Here is the link to the excerpt from this publication. It contains the table of contents. I expect to release this book in January 2021. (I will write a post, when it will be available).
