Hello,
I have installed the latest FG version (2016.1) in Windows. I have been testing the telnet interface to change parameters, as a first step to interface FG with an external controller. I have found that for the included model (Cessna 172p Skyhawk) I cannot change the throttle setting. If I select the option "start with engine on" the engine starts up and the throttle is automatically set to 0.2. If I use the mouse or the keyboard I can change it without any problem. However, if I start the telnet interface the throttle does not change. To be more precise, it seems to change for an instant, but immediately afterwards something internal resets it to its previous value. It is weird, because if I do the same to the elevator it changes without any problem. If I use another model (Dassault/Dornier Alphajet) the throttle does change. I am using the property "controls/engiens/engine/throttle".
Is there a bug in this specific plane? Is there some kind of workaround?
Regards,
JFM
