If the multicopter is capable of flying,
but its behavior is not entirely ideal, it
will be necessary to fine-tune the PID
gains of the stabilization loop - see the

Properties menu. Here you can edit
individual coefficients for each axis
separately.
Proportional coefficient – this is a basic parameter of stabilization.
The response of the control unit is directly proportional to the
desired rotation speed. If the multicopter is not sufficiently
stabilized in some axis, e.g. the pilot must always interfere with the
steering to keep the model in the air, increase this factor (at each
step, for example, by 20%). Once the oscillation starts, reduce the
proportional factor by 20%.
Integral coefficient - determines the weight of stabilization error
accumulated from the past. Thanks to integrating, the receiver is
able to return the model to its original orientation, even if it has
been previously displaced. Set this factor so that the model does
not tilt in the air in any axis and keeps a steady attitude in the Sport
or Acrobatic mode. If the coefficient is too high, slow but strong
oscillations might appear.
Derivative coefficient - The derivative component of the
stabilization loop responds to rapid changes in model orientation
and is able to suppress, for example, the effects of wind gusts. Edit
