Yes I am aware the 11.5 degree setting is approved. My aircraft is Normal Category and I have no complaints about the current setup. I am interested in what most people have their planes setup on and the differences in performance. For example, I can leave my prop in low rpm and start my taxi without getting the backfiring that some do with the 13 degree low stop. Curious as to the effect on takeoff and climb performance.
Why would you keep it in low RPM to taxi? Manuals say to advance after start and you have solid oil pressure. Rings and oil scavenge like RPM. Higher engine speed moves more oil around as well. Just wondering what you feel the advantages are for doing so.
Do you have Standard blower or 12-1 Blower gears?
Backfiring is a mixture thing. Just retard the throttle and it should go away and advance prop for more RPM and it shouldn't bark.
Only Prop setting specs are from TCDS and making 2250 RPM on the engine. Since you have a variety of blade lengths and prop profile and thicknesses from years of use and overhauls its a bit difficult to have any 2 A/C exactly the same. They often each have a personality.
