Wow, thanks a lot John for all this information!
As for the work-around discussed above disabling trim for the pitch axis to solve the issue in the NGX where moving the stab trim will also affect the deflection of the elevator I realized I’m not sure if this really is a work-around. This since disabling trim for the pitch axis of course also means you will no longer be able to feel if the aircraft is correctly trimmed or not but rather it will always be centered requiring the same amount of force to be moved along the pitch axis regardless of the stab trim value.
Or maybe I’m just tired not thinking straight 🙂
Will do some testing tomorrow.
