Hello MP users,

I´m new in adjusting PID controllers and I´m not sure on how to adjust the rudder from y accelerometer. As far as  I understand this loop is being used during level flight, climb and descent to coordinate turns.

My first doubt when adjustin the inner loops (manual page 82) is whether or not the rest of the PID loops should set to zero

I set the rest of the PID loops to zero and I have adjusted the elevator and ailerons (with rudder from y acc with all values to 0) and my plane flight in a stable way but when I insert values in the rudder from y acc (with the fourth term set to zero to de-couple the yaw and roll axis as written in the MP Installation and Operation manual,page 83) the roll and pitch oscilates. Is it normal?

On the ground, should i receive any response from the rudder when I move the plane´s nose with values in the  "rudder from y acc" loop, with or without values in the feedforward i have no response in the rudder. Is it normal or am i´doing something wrong?

I have a rudder response (oppose to movement) only when i set values on the "rudder from heading" loop.

thanks in advance!
