on OSD2.0 or the ground terminal's yellow LED does not flash, try to change the PAL/NTSC format. When
applying NTSC, AAT ground module may need to upgrade.
3. Please reduce the motor vibration to keep the “vibration value” more than 70 (99 is the most ideal
situation).
4. The idle current is 0.8A while turning off the throttle, if the readout is wrong, please enter the OSD menu
and exit to reset the current value.
5. When Arkbird is auto piloting the plane(RTH mode、Cruise flight), the lower right will display Roll, Pitch
control Angle Value and Throttle Value, Adjust Autopilot if these angles not appropriate.
6. Pay attention to GPS satellite quantity, less than 7 will result mistake positioning.。
7. As Arkbird applies anti-interference inertial navigational compass, instead of magnetic compass, there is no
need to do manual calibration. But the flying direction on the compass is incorrect on the ground. 10
seconds after taking off, it will calibrate according to the GPS coordinate. Then compass gets normal.
8. The horizontal position should be identical with the actual horizon. If not, calibrate the sensor again.
7 Manual Mode
Radio Stick and SUB-TRIM back to center, set radio travel range as 100%.
Switching to Manual Mode, Arkbird will not participate control, set manual control’s reverse through radio,
adjust plane’s CG and travel angle, make sure plane can fly stably in horizontal without Autopilot.
Reverse Balance Mode assistant Control
Switching to Balance Mode by pushing CH5 to 100% and CH6 to 0%, if the neutral point is correct, rudder,
aileron and elevator shall be at the neutral position, otherwise, please check the neutral point again.(see OSD
menu -> CTL parameters)
1. Aileron: When rolling the plane to right, aileron shall produce a left compensation automatically, make
plane go back horizontal. On the contrary, when rolling to left, aileron will produce a right compensation. Please
see as below:
If the compensation direction is not correct, please adjust the Roll inverse in OSD menu -> Flight parameters.
2. Elevator: When pitching up the plane, elevator shall produce a down compensation automatically. On
the contrary, when pitching down, elevator will produce an up compensation. Please see as below:
