Spitfire rudder

I have the impression that the rudder of the spit is not very effective. Obviously at higher speeds and higher altitudes it is supposed to get less effective but I found that it almost gets ineffective then and it is not much effective at lower speeds and on ground.

Is this realistic? Just asking.


P.S.: The rudder of the 109 works fine for me so it is not a hardware or control stuff for me.
