120 kts at 18.5 deg.  17 ltrs hr

How many revs. is that ?    I can only get 120 kts (set at 17 deg)  by going
up to 5300 where it is too noisy for comfort. To operate safely out of short
fields I put it down to 16 deg. last summer but the fuel consumption suffered
a lot in the cruise, so I have put it back to 17. I prefer to potter along
quietly at 100 to 105 kts under 5000 rpm  (digitally measured) and get
consumption down  nearer 12 ltr/hr.
