Trim is for cruise only. 1-1-1.15 ata level flight.

i want to clarify somethin neutral mean 0 on trim gage in bf109 right ???
so i tried that trim 0 1.05 ata it is not even remotly close to level flight i need to push stick a lot to maintain level flight when i centre stick bf pulls 3.5g at 400kph and loop is done quite fast i would say about 10s-15s
this is how look my controls during level flight with 1.05 ata
i think something is very wrong here then
and this tendency not change too much even at bigger ata the same at 1.1 1.2 1.3
only way to fly level is trim it all the way +2 and even then it has small tendency to pitch up

or you ment the whole trim range is for cruise only at 1.1 but if it is what you ment thne i can cruise with 1.4 ata with trim all way down so not realy any change in pitch during faster/more power flight

Trimmed level flight is possible only up to 1.1-1,15 ata (at the speed of level flight), i.e. cruise flight. For higher IAS stick input is necessary. "0" means 0 degrees of stab incidence and not more.

but if all of them?
hard to say what was "standard" in that war phase and situation, especially for 109 case...

nope. we only got it for ailerons and rudder, but not for the elevator for some strange reason.

i think it doesnt make much sense that they refuse to give us elevator trim tabs. they were there in real life, and im of the opinion, that this should not only be here for the 109, but for all warbirds on all surfaces where the real life counterpart had them.
