Just some online thoughts..
With current FMs I find the FWs best turning ability between 325-400kph.
When a spit, tempest.. etc uses the vertical I don't follow, but stay level/horizontal and build up my speed, then flip vertical for a quick burst, then down again for speed.
There are times I cut throttle back and play around at stall speed as the allied aircraft do have major difficulty in this area - But I've always said this... and like Gaston I've been 'shot down' verbally for 'heresy'... but many allied a/c have died at this point
you work it out
