Ubuntu 14.10, Flightgear 3.4, Nvidia GTX960
Hi - I wonder if anyone can help. I run Flightgear using dual computers. The main computer runs dual screens showing the view from the cockpit. A second computer runs Flightgear with FDM=null showing a view of the aircraft from outside ie chase view or something and FGpanel for instruments on a second monitor. All works brilliantly really - but I notice that for some aircraft the propellers on the second monitor remain stationary when the motors are started on the main computer (where the propellers always rotate when started). All other aspects of the aircraft appear to be transmitted to the second computer ie attitude, flaps go up and down and rudder and wheels move as expected - just the propellers get ignored! (propellers move on the second computer when it is running Flightgear on its own as a normal system).
C172 - propellers rotate on both computers
DHC6 - propellers do not rotate on second computer
DHC8 - propellers do not rotate on second computer
DHC2 - propellers rotate on both computers
C130 - propellers rotate on both computers
So I'm guessing that it's an aircraft problem rather than a generic Flightgear problem. However I don't know where to begin to try and solve it and wondered if someone who has built an aircraft could provide some advice. I'm not a Nasal programmer but I understand a bit of code - but not enough to know where to look or what to change if I found it. Any help appreciated.
