Nick,
One thing I’ve noticed on the ALP-46 is that pantograph control does not work. Works fine on the DCS remote.
Does it fail to raise and lower when direction changes and it's in automatic mode, or does it fail to raise and lower manually in manual mode, or both?
I have this engine and haven't seen this issue, however, I may not have run it with he most current app.
BTW, ensure that you have DCS 6.1 in the TIU, 1.1 firmware in the WIU and app version 3.1.0.
