I had to make an account here, I just bought the sabre and it's my first experience with DCS. I love the details.
Here are some good books I can recommend:
Best overall work
Sabres over MiG Alley by Ken Werrell
Good pictures, development and combat history
F-86 Sabre by Robert F. Dorr
Good small book, has tech and tactics etc
Sabre vs MiG Osprey Duel
Good for Technical info regarding various models
F-86 in Action
Hope this helps you get started. I have a few more on order that I have not read yet.
