The automatic cruse setting of the Airmaster controler gives us 118Kt IAS @
5000rpm and 25.5" for a 19 l/h consumption. Trimmed on a manuel mode we
can't have better than 120Kt IAS @ 4800 rpm and 26" for 18 l/H

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.)
