Got a response from Anne LAVRAND President / Sales Manager at eProps.  They think the prop is tuned where's it needs to be.  She even indicated that the WT9 with 912iS only gets 4800 on climb out and has been blessed by Rotax.

Thanks everyone for the advice.

Ok,  We're finally flying with our Just Aircraft Highlander with a Rotax 912is Sport engine and the 3 blade ground adjustable Durandal eProp.  We're currently seeing  5450-5500 RPM at WOT level cruise (Alt 3000ft and MAP is 26.5 inHg) and 5000-5050 RPM in sustained climbs.  This seems to be where eProps wants the WOT level flight RPM.  Should we decrease the prop to get our climb RPM up a little higher?  We realize we'll hurt our top end cruise speed and improve our climb performance.  We're also trying to balance the 912is engine with it's Power/ECO modes.  

What is everyone's thoughts here?

Kyle,  Did you ever hear back from the Highlander owner?

Kyle, Any Just Aircraft Highlanders using the E-Props in Australia?  In talking with E-Props, they've told me there are six Highlanders with E-props, but didn't say where.  Like the OP, I'm just looking for first hand knowledge.  We've just mounted our Rotax on the airframe, so we've got time to decide.
