You are correct, the Aviatik C.I can handle the N.11 fairly well. I found that if I acted aggressively when they attacked that it confused their attack and gave me a good chance of going on the offensive. Remember, you can also fire forward to some extent and that really messes with their heads.
Yeah, it does! My intrepid pilot had a scrap with two N10s the other day and nearly bagged his second victory. I do get a little upset with my gunner though, when he fixates on the one that's further away. Also, he tends to forget about his second gun!
I'm "Stutter Free" At Last! God bless WOFF, and all who fly with her!
