If nothing else it would seem that turning right with a Dr.1 on your butt is not a good idea. Turning left seems to give the Dr.1 pilot more problems, especially if you can make it a climbing left. I suspect that may be rather difficult in the Camel however.
Straining myself to think of a plane that has a tendency to pull to the left and has an excellent climbing turn.
Ding dong, it's Noop 28 o'clock!
Oh and what big fat targets these slow turning Dr. 1 pseudo-Richthofens will be!
