I have my x, y calibration setup so I have removed 10,000 from each end. To control the input I then have scaling enabled to slow down the first third of the input. Makes the nose very smooth with very little stick input.
I always backup my settings and other folders each month and just before installing a new patch. Usually I download the full install and uninstall the previous version. So I have a record of my x, y scaling settings for some time back.
With 2.31 my y-axis input became magnified to the point I was pulling into blackouts, wing stalls, and rapid E loss almost by looking at the joystick. On full zoom chasing drones, it looked like I was popping my nose up and down with almost no ability to hold a smooth center for shooting with very tiny stick inputs. Ground attacking tank drones with the Ju87-G2 was futile due to over compensating the y=axis of the nose trying to hold a steady AoA for a firing solution. This is because of the inertia from the BK3.5 under the wings. I have no potentiometer spiking in my Y-axis POT. I use DIView regularly to check this.
The Ju87-G2 is an excellent test of your joystick's smoothness or jumpiness offline on full zoom due to the inertia of the heavy guns under the wings. How smoothly can you make micro adjustments to hold for a firing solution?
The solution was in the y-axis scaling.
I had to pull my starting point for the initial curve down to 1\4 from 1\2 and reshape the left to right curve up to 100% with the first three sliders almost parallel before curving the rest up. With 2.31 the force describing the x-axis became "stronger" for a lack of a correct technical term.
