Hi guys
I hope many more rotax fliers chime in here.
On my 912 UL I usually run at 5200 on "fast cruise" and 5800 on takeoff, putting some pitch in for climb out at 5500.
But my manifold pressure in cruise is 27+ . It has always concerned me but everything seems to run and sound right.
I am using a 70 inch IVO IFA Ultralight. Fuel burn averages 15 litres hour. Just over 600 hours on mid 90's engine. No oil use. No repairs just plugs and filters.
In order to get my map lower I have to either reduce rpm or fly down hill. Not always practical choices .
Are these numbers about the same for everyone?
Cheers
Don
