Setting mixture levels?

[TomcatViP]

Yes I am gradually leaning for cruise from full to 50% (I use the "T" of the "shut" throttle sign as a mark)

Experience seems to show me that :
- leaning increase the range (rotol hurri) and can be seen even on the first tank
- on some hurri (depending on base and on the way you warm your eng) it's not advisable to set back to full rich for a fight and need to lean depending of your height to get some power during a significant time.

Before I realized that there was 4 tanks in the Hurri instead of just one a la Il2 I could stay airborne 45 min at alt only if I did lean the mixt during the cruise. Otherwise the tank gauge (in fact showing the first tank only) would be on the empty mark
