After a couple of very short campaign with the Camel I was determined to learn to fly this plane.
I spent a week of just QC with the Camel, I am not sure how many hours but at least 8 after which I felt I was finally starting to get a good grasp of the plane although I would still spin or stall occasionaly (sometimes on purpose)
The tips that I have found to work for me, lots of left rudder, easy and smooth on the controls, throttling back while making any hard maneuver throttle back up when you are going straight and level. There is not a lot of feedback for the sim to give you a feel for when you are close to the edge, but with lots of cockpit time you will get better.
