If the parameter value is too small, the FC will control the
airframe pitching and rolling on its axis too slowly, resulting in poor
stability .
If the value is too high, axial oscillations will occur.
Heading

Heading
Heading
Locking
(1) Locking
Locking
Locking Coefficient refers to the corrective action taken by the FC
to maintain flight heading hold.
If the value is too small, the heading hold will be too slow
resulting in directional drifting.
If the value is too high, heading hold will be carried out too
quickly resulting in oscillations.

Locking
Locking Continue refers to the degree of heading recovery given by
the controller in unit time .
If the value is too small, there will be a constant deviation between
the actual heading angle and the objective heading angle. This results
in difficulty to reach the objective flight heading angle.

But if the value is too high, the aircraft can experience oscillations
during flight.
Stability
(3) Stability
Stability
Stability Coefficient controls the degree of angular rate
convergence when the airframe moves vertically (Z axis).
This parameter prevents movement of the aircraft along this Z
axis, especially during changes in aircraft heading.
If the value is too small, the airframe will move in pitch and roll
axis, resulting in aircraft instability.
If the parameter value is too high, oscillation will occur.

Letter P represents the degree of movement control given by the
controller when there is a deviation between airframe position and
objective hovering position.
If the value is too small, hovering position recovery will be too slow
resulting in instability during a hover procedure.
If the value is too high, oscillations will occur when in the
hovering position.
Letter
(3) Letter
Letter
Letter I represents the degree of control to move in unit time given
by the controller when there is a deviation between airframe position
and objective hovering position.
If the value is too small, there will be a deviation between the
actual airframe position and objective hovering position, making it
more difficult to reach the objective hovering position.
If the value is too large, oscillations will easily occur during
aircraft hovering.

Letter
Letter D represents the degree of control given by the controller
which is used to prevent moving to the axis(X/Y) when the aircraft is
in flight.
If the value is too small, the heading hold function of the aircraft
will be poor when directional changes are carried out.
If the value is too high, oscillations will occur during flight.

Altitude
(1) Altitude
Altitude
Altitude Compensation is the degree of control to compensate power in the
process of positioning movement. That is, the amount of power used to change
airframe position during flight.
Example, when altitude is lost during de s cent, Altitude Compensation is used to
increase power to compensate the lost of propeller lifting force.
Note that if the descent altitude lost rate is too fast resulting in poor stability, you
should increase the value of this parameter.

Speed
Speed
Speed Control is the degree of input used to control the entry
speed rate to a target position.
T he aircraft will reach the destination with a certain speed when
near the target . The FY91Q will give a Speed Control input for either
deceleration or acceleration.
If the Speed Control value is too small, deceleration or
acceleration may be initiated too slowly resulting in the aircraft
deviating the objective hovering position.
