I sometimes react before I think!
That is how you ride a bicycle ! ! Try to think a few seconds ahead and have the correction ready for where you want to be after getting on top of the current divergence.
Before you know it you will be following a straight path and your cyclic movements will reduce to almost nothing.
Try a larger circuit on an airfield following taxiways and a runway.
Use the normal control menu to set up rudder, aileron and elevator trim on your keyboard or joystick buttons. On my number keypad I have 8 and 2 for elevator down and up, 4 and 6 for rudder left and right and 1 and 3 for aileron. Having no constant force on the joystick is much easier.
Well done and keep practising.
