Hi Innis, This is Maik Justus' work and he's really done an excellent job of doing what you've described (thanks for the description btw). As far as I can tell he is not (yet?) modeling the engine or throttle in any detail. But given the limitations of joysticks, the "throttle axis" is probably the best place for the collective. The one in FlyII does the same thing. In the FlyII manual it suggests inverting the control mapping if your hardware has a lever, since the collective lever is usually pulled to go up. Any chance you could take some detailed helo cockpit photos while at work? :-) Best, Jim _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
