The high power controller uses 5v reference because there is an amplifier for current measurement. This allows rudder feedback to be ratiometric. The regular controller uses 1.1v reference to get a better resolution on current current, which causes 1.1v reference for all adc measurements including rudder feedback.
I cannot just add resistors to the design. It would be bad for the hall sensor which draws a constant 13 milliamps. It would reduce resolution in other cases. It is better you add resistors if you need them for now. Eventually, if there is a controller specific for a particular actuator or something it could make sense.
As for "steering aid" the "absolute pilot" implementation makes use of rudder feedback in the control loop but I have no feedback or testing on this yet.
