Thomas Kreitler did most of the work. Originally I was using Jack Mermod's AH-1 model, but it was too advanced for my needs, so I borrowed the sound configuration, and studied the way Jack integrated the model with FlightGear. Note that some more work needs to be done with the propulsion models in JSBSim in order to get this finished. Until then the engines used here are electric, so you won't see turboshaft engine parameters. At sim start-up you'll be on the ground. The throttle slider on your joystick is your collective control. The slider should be full forward for minimum collective. You may have to jiggle the slider first to convince the simulator that is in fact full forward (since the start-up default assumes full aft slider). Press the "u" key to engage the rotor governor. Press "j" to close the rotor clutch. The rotors will spin up to operating speed. After landing, press "u" to disengage the rotor governor. The rotors will spin down slowly. You can brake them by pressing the "k" key to toggle the rotor brake.
