I would like to inform if there are books on scale technicks and especially in Pre WWII Planes.
Rigging, Stitching, Pinking etc.
Also if there is any Video i would appreciate to know about it.
Finally i am interesting also for a book or a video for covering technicks and especially for fabric coverings.
Thank you all very much for your time.

Dave Platt's "Black Art" videos are supposed to be very good. I've never seen them but I've seen his airplanes and WOW!

Model Airplane News publishes a widely available book on scale detailing that includes an article on how to do rib stitching:

But you'll learn more from following the build-alongs by the master builders on the following site than you would from any book!
