Hardware in the loop problem [express]

Hi

I am a student of aeronautical engineering, the next week I have a presentation of a work I’ve done with ArduPilot and RPI. For obvious reasons, I can not fly the plane in the presentation. To the more dynamic presentation, I thought about assembling the plane and install the HIL with FlightGear to see a simulation.

I can see how the FG communicates with MP, because the position and actions in the ‘FG’ are seen in the MP.

But the actions of the radio or autopilot to control the aircraft have no effect on the FG. Neither these actions move the actuators (ailerons, elevator, engine …), the actuators move perfectly until the moment to start the connection with FS.

The presentation is on Tuesday 26, I need your help please!
