Max Dow
n to make plane pitch up and down smoothly. (Too prompt or slow are
improper)
4. Based on how far and high expect to fly, adjust

FAQ and Solutions
：
★
When switching to Balance Mode, the elevator will lift up a bit because the “Elevate Angle in a level flight”
in the menu is defaulted as 5°. Which means the plane will rise a bit in a level flight to ensure a level route.
★
If the CH1 has touched the edge but you cannot enter the menu, please check if the route setup is too small
on the remote control.
★
It’s normal when the direction of compass and return arrow is inaccurate while testing on the ground. The
data will be calibrated by GPS in 10s after the plane takes off.

incomplete
A

Q
：
Cannot locate home, displaying “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.
