Maybe it's not an issue as such then, only I feel that trimming the aircraft is not as intuitive as I imagined it to be. I also use the hat switch to trim and manage to get by ok. I fly the Russian jets almost exclusively and if this is how they are meant to fly then that's fine.
Incidentally, I've noticed that the Russian aircraft have 'ТРИМ' marked on top of the stick, right above where the hat switch is located on most gaming sticks. Is this how the actual aircraft are trimmed then?
