Dave, I have not studied this carefully to fully answer your question, however you should start by using "min-deg" and "max-deg" since with "rotate" callbacks the units being output are not arbitrary, rather they are in fact degrees. For some time now, it is the standard in FlightGear/SimGear to try and include the type of units in the property names when they are known (e.g. -ft, -m, -deg). It is easy to forget though, when playing with animations.
