Suggestion: Set your hat switch (Left and right or up and down) to control prop pitch.... most times you are after a setting of 2.3 or 2.4 so, once you are in the air, if you set the prop pitch around there and keep an eye on it, it shouldn't be too difficult to maintain that pitch even in a combat situation. After awhile you will get used to it and know when to increase it or decrease it (To always maintain that magic reading) when climbing, diving etc.
The auto prop pitch in the 109 is working pretty well now so, on occasions where I can't be bothered, it is usually safe to switch to auto when in combat.... though you will get the best performance out of the bird using manual.
