I am not able to reproduce these stability problems on my own system. Can
someone summarize how to reproduce these problems and which version of
FlightGear they are using? Using udp socket communication and Fedora Core 8
here, things seem to be running really well for me.
the most significant problem seems to be that some important data isn't

There is an --native-ctrls= command line option to send a set of flight
control related properties. It works just like the --native-fdm option,
just remember to use a different port number.
For past projects, I've used the --props= option to accept property
configuration changes (things like weather effects and time of day.) You
can use this interface to read/write individual properties. I setup a
separate gui that was configured to know the ip addresses of all the slaves
so it could update them appropriately when I wanted to make a change. For
the time of day, this presupposes that all the computer clocks are pretty
closely in sync ... then you can send the same time offset to them (in
seconds) so they all can display the same time of day effects.
Is there an accepted, already existing solution to this? Or should we

I'm still interested in getting to the bottom of any master/slave problems
since this is a critical feature for some of my future day job work.
Best regards,
Curt.
