Skills for Balance Mode and RTH Mode
The Arkbird flight control has an intelligent adaptive control algorithm, which automatically collects the throttle
for horizontal flight. If the rudder angle is installed properly, there is no need to adjust any parameters, but if you
want to achieve the most ideal state, you can debug according to the following methods:
After the first installation, enter the OSD menu to perform a level calibration. After calibration, tilt the flight
control 45 degrees left and right to observe whether the horizon movement in the OSD is correct. Whether it
quickly fits close to the actual horizon.
During the flight test, please test the flight with the default parameters first, make a ground
recording, observe the flight data and adjust the parameters through the OSD data.
Adjusting Balance Mode:
Purpose: Stick and SUB-TRIM back to center, plane can be able to flight forward levelly.
The control ctl value is equivalent to the mechanical movement angle of servo arm. Generally,
the default value is selected. However, if the control value is too large and plane shake obviously,
please reduce the ctl value or the movement angle of the servo arm of the corresponding channel.
When the joystick returns to the center, the head cannot be leveled, or the head is lowered or
raised. Please increase or decrease the value of the "angle of attack for level flight" (do not
use the joystick to fine-tune, otherwise the return mode will be inaccurate)
You can increase the yaw ctl (direction control value) appropriately to increase the heading
stability. Please increase this value if it is easy to be deflected by a crosswind, or if you
return home in S-shape when returning home.
Adjusting Return to Home Mode:
Switch to RTH Mode, important parameters
“RTH Angle,” “Roll Control Value,” “Pitch Control Value,” and
“Throttle Control Value”
shown on OSD shall be checked all the time. Flying to certain height, switch to RTH Mode
and check if these data are appropriate.
