For an axis in the range [0-1] use something like this: <axis n="0"> <desc>Heading Bug</desc> <binding> <command>property-scale</command> <property>autopilot/settings/heading-bug-deg</property> <dead-band type="double">0.0</dead-band> <offset type="double">0.0</offset> <factor type="double">360.0</factor> </binding> </axis> For an axis in the range [-1,1] use this: <axis n="0"> <desc>Heading Bug</desc> <binding> <command>property-scale</command> <property>autopilot/settings/heading-bug-deg</property> <dead-band type="double">0.0</dead-band> <offset type="double">1.0</offset> <factor type="double">180.0</factor> </binding> </axis> Even a 10 bit pot axis will give better than 1/2 degree selection. Jitter might be a problem. ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
