We usuably cruise with 27" and about 4500 rpm if we are not in a
hurry, which is about 16 l/h fuel, and good for about 120 IAS.
I think for 30" you should go to about 5000 rpm. There is some curve
about that in some Rotax manual. Of course it also depends on the
balance of your prop (I have a two blade prop, and it feels just a bit
more rough in the area of 4600 to 4800 rpm, so I avoid that area.)
Frans
