ridiculous uncontrollable engine torque on airplane models.

This is because the Bf 109 tail is a vertical aerofoil tuned to cancel the engine torque at apporoximately cruise to combat power settings in the 400-500 km/h range. Slower than that and this vertical "wing" does not produce enough sideways "lift", so you need right rudder. Faster than that and the sideways lift on the tail is swinging the nose too far to the right, so you need left rudder now to cancel it.

 

That explains it.  

Anyway....  While I'm here.....

 

Do you know if the P-51 has a similar vertical stabilizer design?  I mean that thing needs right trim and right rudder to keep it on the runway, then the moment the gear is up, it switches left.   (Yes, this is with combat-approved fuel levels.) Come to think of it, the whole plane flies like a bobble head mounted on a spring at the center of the radiator scoop. Of all the planes in IL-2, it definitely wins the Trim Queen award as in, you need to trim it constantly and don't accidentally over-trim it if you're changing speed range, altitude and orientation attitude rapidly or you'll pay.

Not that I'm aware of, but it might have some other aerodynamic quirk. I'm starting to pay more attention recently to centering the ball and trim generally, but I haven't noticed anything weird about the Mustang. I used to fly it ignoring trim completely without issues. If it's too bouncy try adding some curves to your axes?

agreed, the fw190s pull right then at 30% throttle pull hard left.

has to be a bug.

This is because the 190s rudder is partially trimmed to the right by default.

 

At 30 throttle, the trim moves the plane right.

At 100 throttle the torque is more powerful than the trim and the plane moves left.

One of the beautiful things about flying is the way different effects come together and become more apparent in terms of their effects in some situations, while disappearing from your perception in others. People expect a linear behavior, then it isn't there and they get perplexed. It's just natural.

I've got some pretty strong curves in the axes to start.  It brings me to a point where I wish there could be custom curves that can be saved for each plane. 

For the most part, if you have a good amount of time to climb out without having to maneuver too much, you can trim the P-51 for hands-free flight. Granted, "hands-free" still requires some minimal correction inputs but, that is kind of the nature of almost any fighter at it's ideal straight-and-level cruise speed.  The P-51 seems to take some extra work to get to that point though.
