(

float

pitch

)

stabilization_attitude_heli_indi_set_steadystate_pitch

Parameters

pitch

neutral pitch angle [deg].

Change the neutral pitch angle.

(

void

)

stabilization_attitude_heli_indi_set_steadystate_pitchroll

Updates the neutral pitch and roll angles and calculates the compensation quaternion.

(

float

roll

)

stabilization_attitude_heli_indi_set_steadystate_roll

Parameters

roll	neutral roll angle [deg].

Change the neutral roll angle. Especially useful for helicopters, since they need a small roll angle in hover to compensate the tail force.
