Testing new FGRotor and FGElectric mods, using Alpha-J's AH-1S model. It seems to fly right, but I'm no chopper pilot, so can't tell for sure. The JSBSim FDM uses a rotor governor system, designed by Thomas Kreitler, and the standard FlightGear throttle-slider-controls-collective feature. There are also key bindings for the rotor brake and clutch. I also added a kill switch that cuts power to the rotor, in order to test the free wheeling unit and autorotating behavior.
