I was discussing this with BIGNEWY on the ED Discord, and he suggested I make a thread on this.
I have noticed an "over trim" or "over sensitive" Roll Trim when trimming out asymmetric loads. What I mean by this is, it is next to impossible to trim out the unwanted roll due to how much roll trim is applied by just tapping the trim hat left and right. I find my self tapping left and right over and over in hope to counter the unwanted roll.
Heatblur did something to combat this early on in the EA release. They reduced how much roll and pitch was entered for every tap of the trim hat. They also enabled an accelerated trim function, ie. holding down the trim hat in any direction will increase how quick the trim hat trims the jet.
Hopefully this is something ED can incorporate, at least on the roll trim as pitch trim is hardly needed thanks to the FLCS.
