[Paparazzi-devel] roll_trim

I set the roll trim and pitch trim in the airframe file like that:

     <define name="COMMAND_PITCH_TRIM" value="350"/>
      <define name="COMMAND_ROLL_TRIM" value="900"/>

I put the plane on a flat table and powered on. Then I set the roll trim from GCS which is same with airframe (900), then the ailerons move. Same situation for pitch trim. Since the setting value is same, I don't expext them to move. Our paparazzi version is v5.1_devel-126-g1757e2e-dirty.

We are using energy control loops, which updates the aircraft characteristics below. Although there is no variable about roll, can this situation be due to this?

By the way, we want to add the ac_characteristics to the telemetry. Did somebody add it before?

// Automatically found airplane characteristics
162 float ac_char_climb_max = 0.0f;
