luthier, the historical performance btw 109/spitfire/huricane is NOT simulated in CoD

Zapatista you said :

"- had similar level flight speeds and climb rates to the spitfires at low and medium altitudes (except at high altitude where they had an advantage initially),
- could spiral climb out of reach of a chasing spitfire, the combined climb/rudder action was a unique strenght for that plane model (shape/size/wheight) during most of the war"

This is confusing how can the 109 have a similar climb performance in normal climbs but better climb performance in a spiral climb ?

What is a combined Climb/rudder action ? Any rudder other than that that ensures balanced flight will increase drag and therefore reduce climb performance.
