I would additionally recomment to learn the plane at slowest possible speeds near stall. It takes some time I think (in 1946 it was a lot easier to fly a 109 at 120kmph and still have good controls), but if you can comfortably control the 109 near stall speeds, you will have no problems at high speeds either. At the moment I see many players struggling with their planes, be it Hurricane, Spit or 109 at the low speed regime, so everyone is facing the new behavior of CloD compared to 1946. It is really fun to scissor in a 109 with a Hurricane and watching the Hurri having the same problems as you have. The most pilots never tried or needed to manouver their planes at these near stall speeds, so I often find myself stalling out simutanously with my opponent at lower than 100m.
It`s fun, you can almost see the surpised faces of the Hurricane and Spit Pilots, when they meet a 109 not running like hell, but trying to fly slower than them - and it`s good a good exercise. I am slowly staring to get the hang of the 109, but there are still some suprises left.
