Hello Erik, Are you sure the differential tail deflections can't be done in JSBSim? I was faced with a similar situation when I recently started re-working the YASim TSR-2, which shouldn't have any ailerons at all and what I've done is to bind the aileron input to the elevators, at the same time defining the input as 'split' so that the surfaces oppose each other in response to this control input. It seems to work well, apart from being too sensitive - I have to set the joystick aileron axis factor to 0.2 using a --prop entry on the command line to make it controlable but otherwise it seems fine. I'm not very familier with JSBSim so I don't know if a similar thing could be done.
