10 Other FAQ：
Q: The fourth channel always has rudder output, does not return to the center.
A: Check if the steering correction function is enabled and turn off this mode;
Q: After the steering lock function is activated, the rudder drifts in one direction.
A: Check the installation direction and recalibrate the sensor. Fine tune the steering input on the
remote control;
Q: Both lights are on and off at the same time, and there is still rudder when the balance mode
joystick returns to the center.
A: Check the installation direction and recalibrate the sensor. If it still does not work, it may be
due to sensor damage;
Q: The throttle has a output, or when the throttle lever is at its lowest position, the throttle
beeps and does not work.
A: This is an incorrect setting for the ESC electric throttle stroke. Please unplug the propeller, fine
tune the throttle channel on the remote control to return to the center, and set the rudder to
100%. Then directly plug the electrical adjustment into channel 3 of the receiver, and refer to the
electrical adjustment manual to calibrate the electrical adjustment stroke.
Q： Cannot locate home, “Waiting GPS Home”
A： Seeing OSD “Waiting GPS Home” proves GPS wiring is OK, otherwise, please check GPS
wiring.
GPS’s white antenna shall face up; keep GPS away from Video TX and Camera. Some inferior
Video TX’s antenna will affect GPS, too. You can try to remove the casing of GPS, or put a layer of
tin foil paper under GPS to enhance the performance.
GPS can only work Outdoors, First time about 5-10 minutes, next power on of the same day
it would take less than 10seconds to locate.
Q： Plane tilts under Balance Mode / Manual Mode, can I adjust the radio TRIM?
A： First time installation, do a neutral point alignment. Radio stick and SUB-TRIM back to center,
adjust plane’s CG and travel angle to make plane balanced.
Arkbird can produce compensation when CG & travel angle is not appropriate, but it is not
mechanical stable, there would be hidden trouble under RTH mode. So firstly make sure plane
can fly stably in horizontal under Manual Mode.
Q：Inaccurate Return-To-Home
A： Adjust remote control rudder angle to 100% and sub-trim back to center. Check carefully in
reference to the “Debugging Skills for Balance and RTH Mode” chapter of our instructions.
Make ground video recordings. These data will tell you if the control values are proper and
will help you judge which parameter needs to be sub-trimmed.
