I am about to begin a book on unmanned vehicles and wanted to include a few types from ardupilot forum for reference and need some images. Reference to the link will of course be provided.
I saw that Ardupilot has mentioned the content as CC-by-SA. However, I would like to get clarification or permission to use images in my book. (country of origin of the book will be India).
Please help. Thank you so much.
