I dont use CT, man trim only......
The above image is how the a8 needs to be manually trimmed for level flight.
In a dive the nose up tendency is much greater. Trimming the elv all the way down doesnt prevent it from nosing up.
The a8 was very stable gun platform in AH. Now in AH2 you have to fight the nose up (some roll as well) to line up a shots.
I dont know about other planes but the a8 is bad....
