I realise Il-2s implementation of this is not great, however, a competent pilot will trim as he fights, and pre-empt situations. I suggest you start flying the P-38 to learn how to do that effectively.

I bought a X52 more than 3 years ago. The stick has non-contact sensors on the main axes. That makes the use of exponential output tables unnecessary. I use the 10, 20, 30... 100 - linear output.
I found out very soon after that, the trimming is no longer indispensable. Stick forces on a X52 are quite a bit lower than on a P38, you ll agree. Once the jerky character of the exponential output has been removed, I didnt feel a real need for trim. Other, more energy sensitive friends of mine still do.
Trim tabs DO influence the control surface effect in real life, too. Take a look at their picture somewhere; deflecting the control surface, they deflect the airstream in the oposite direction slightly. And more, the trimming has a price in drag, too- no matter if you do it with a tab or the stick. ( It s more with the stick, cause your hand not so steady, etc)
As for the game-in my experience trimming does reduce the maximum throw of a control, even if that should not be so. A plane I always trim is the Japanese Ki43- it has a strong nose up tendency, too. Trimming the nose down reduces the maximum upward throw of the elevatror strongly. Shouldn't be like that, but it is.
All that said- the upward trim is a minor problem, compared to the stability of the 4.10 Spit.
