Hi!
I have a similar problem. I have two networked X-Plane installs, one is Master and the other is Slave.
Master - displays front outside view + PFD + MFD
Slave - displays left and right outside view
Flight controls are attached to Master.
The problem is that the TBM model running on Slave lives its own life. It flies in sync with the Master, but TBM extra functions are not in sync. Like closing the door etc. I have to close the door twice - first in Master and then in Slave.
My question is - how to setup TBM in networked Master and Slave environments? Is it possible at all?
