rudder trim not working?

Hello all,

I've really been enjoying the 109 lately, but for the life of me, I can't figure out how to get the rudder trim to work.

I see in the controls there's the "One Notch" left and right. But those key's don't seem to do anything. And it won't allow me to bind those controls to my HOTAS since the binding boxes to the right of the "keyboard" is all "white'd" out ... if that's even a word.

There also doesn't seem to be an Axis command for it.

Am I doing something wrong? What am I missing?

Thanks guys

The 109 doesn't have inflight adjustable rudder trim - just stabilator.

Ground adjustable rudder and aileron trim tabs can be tuned in the "Special" options of the module. The elevator trim tab, which is also ground adjustable IRL, is not adjustable in any way in DCS (probably due to flight model limitations )

That answers that. thank you. I'll have to do some test flights to see what tab settings keep the aircraft coordinated at a normal cruise speed (or a little higher) I always have issues with keeping the ball centered as I go in on a gun run, and especially when dive bombing.

Thanks again.

As I read from rw pilot notes, at higher speeds / dives, a good deal of left rudder was required, to the point of the saying that "109 pilots were chosen among those with a longer left leg ..." :-)

Shouldn't that be right rudder?

But otherwise, I read the same, that the 109 had a tendency to need constant right rudder in flight.

I see this reflected in the DCS 109 as well.

What is interesting, I am just reading Eric Brown's autobiography (very interesting read), and he mentions somewhere the very varying quality of trim in the different individual aircraft.

Some of them could hardly fly straight, others were like on rails.

Depends Sporg. At higher power settings, AoA, right rudder is required to counter the prop effects, but at cruise and higher speed lower power regimes, the asymmetric vertical fin airfoil and the aileron and rudder trim tabs over-compensate and the left tendencies turn to right tendencies, requiring left rudder...

Since most of the time the flights were performed under that regime, the stress on the left leg could become significant for 109 pilots...
