I have the same progrmme. It get from FlightGear terrain elevation and
send to FG airplane position, orientation, control deposition, etc. The only
difference is that I have to modify generic protocol for binary i/o.

Do you really run 2 FlightGear instances at a single PC at 1000Hz? Try
to run at 100Hz or less.
I think commans must be :
(master) fgfs --generic=socket,out,100,127.0.0.1,7755,udp,udptest
(slave) fgfs --generic=socket,in,100,,7755,udp,udptest --fdm=external
You may try to change host from "127.0.0.1" to "localhost" on master
instance.
If you using firewall make sure to open port 7755. I really had this problem
with firewall.
If this will not help, check udptest.xml as I have wrote. What is in
<input></input> tags.
With respect,
Alex
