RudderTrim Offset Value

Hi Guys.

I hope somebody can help me or can link me to a helpfull topic.

A.t.m. i try to rebuild the RudderTrim Display  (Lower Pedestal)

Basicly i have done all stuff till now via FSUIPC Offsets ( Whatever Standard Range or the PMDG Table )

At the Rudder Trim i get a Problem.   Looks like the Information there is not supported.   BUT i see that CP-FLIGHT sells a Premade Panel taht is compatible to PMDG ( And other AddOns)   So the needed Data "should" be somewhere.

What i still do:

PMDG looks like have no offset in there own Range for that   (Same like ElevatorTrim for the Wheel and the Analog Gauge)

The FSUIPC Value for Elevator is for example 0BB2 and work fine. .......  For "RudderTrim" this would be "0C02" BUt this offset not act to the PMDG Trim Settings.

If i trim the Rudder in PMDG then the RAW Rudder Value (0BBC) will show the changing of Position.....    But this not helps cause it also show a moving of the Rudder when i use my Pedals.

Summary.  

Anybody knows a Offset, that show me a value i can use directly for that gauge  ( The Data that is used also internal in PMDG to run this virtual Display ??
