time, you will not be able to record new AB waypoints.
5.1.6 Auto-return-to-home mode
Auto-return-to-home mode provides the safety guarantee for long-distance flight
and FS protection.
1、Working condition
The working condition is as same as GPS-angle mode. FCU will record the
current position as the return-to-home waypoint when everytime users unclock the
aircraft. If the aircraft is in the mode, LED will be flashed green quickly.
2、Operation description
The automatic return-to-home mode can be triggered by control stick, also can be
triggered through lost control protection. When CH6 switch to one-key
return-to-home position or the FCU is in FS protection status, the aircraft will
automatically lift to a set altitude if the distance between the aircraft and the return
waypoint is more than 2m(if the current altitude is higher than the setting
return-to-home altitude, it takes the current altitude for return-to-home). During
return-to-home the aircraft won’t be interfered manually by the control stick channel.
After the aircraft arrives at the return-to-home waypoint, firstly it will hover for about
3 seconds, and then slowly land, at this time you can control the flight status of the
aircraft (but no response to throttle stick) by the ch1 ch2 ch4 channels, which making
the aircraft to seek a more suitable landing place. Until the aircraft landing completes,
the aircraft will lock automatically. If the distance between the aircraft and
return-to-homewaypoint is less than 2m, the aircraft will land and lock automatically.

Attentions
1. The premise of automatic return-to-home is that the aircraft return-to-home
waypoint has been recorded. If you need to use automatic return-to-home, please arm
it after searching satellite . You can refer to the appendix about LED tricolored light
indication and meaning.
2. When the aircraft is near people, we suggestted not to switch into the automatic
return-to-home mode in case of accident.

5.3 Introduction to the Functions of Remote Controller
5.3.1Arm And Disarm
1.Arm
You can arm the aircraft as is shown in following figure. The motor will be in an
idling status after being armed.
JIYI Robotics CO. Ltd
Page 24
24
2.Disarm
(1)Lmmediate disarmed
under all control modes, as long as motor is turned on, motors will stop spinning
immediately after you pull the sticks as it is shown in following figure.
Note:Do not pull the stick as is shown in the above figure during flight, otherwise the
motor will stop spinning immediately.
(2)Auto disarmed
a.No matter what flight mode it is in, if the aircraft doesn’t take off and at the same
time the throttle is put at lowest level after it is armed, and there are no operations in 3
seconds, the motors will be disarmed automatically.
b.Except in ATT-STA mode, FCU can auto recognize landing, and the aircraft will
stop automatically.
c.Except in ATT-STA mode, if the throttle is put at lowest level, the motor will not
stop spinning.
5.3.2Accelerometer calibration
Flight controller supports horizontal accelerometer calibration with remote controller,
and the calibration method is as follows.
1、Place aircraft horizontally.
2、Switch the return-to-home channel to the highest position, push the control stick of
the remote controller as ↘↗ (American style remote controller) or ↗↘ (Japanese
style remote controller), and when there is an alternating blinking of red, green and
yellow light, accelerometer calibration starts. The calibration will complete in 1 or 2
second(s), and then the LED light will blink normally.
5.3.3Compass Calibration
Flight controller supports compass calibration on remote controller.
JIYI Robotics CO. Ltd
Page 25
25
Quickly shift back and forward the 5thchannel before the fight controller is armed,
and then it will enter compass calibration mode. The solid yellow light indicates it is
in horizontal calibration. Place aircraft horizontally at the moment, and do clockwise
rotation around the axis along with the gravity direction. When the LED green light is
solid on, it enters in vertical direction calibration. Put the nose face-down, rotate the
aircraft round the axis along with the gravity direction until the LED red light, green
light and yellow light blink alternately, and that indicates calibration is completed.
After calibration is completed, it will exit from calibration mode automatically,
LED indicatorblinks normally.
Attentions:
When the flight field changes, you need to calibrate magnetic compass.
Before calibration, please check whether there’s strong magnetic interference
nearby or not.
5.3.4 Motor Test
Motor test function includes motor sequence test and movement direction test. It
is mainly used to inspect whether the installation sequence number and rotation
direction of motor are correctly or not . It can avoid the error installation and
accident from happening.
1、Motor Sequence Test
When the aircraft is disarmed, push the LH stick of the remote controller as ↙
prevent
and make the RH stick to do anti-clockwise circling (American style remote
controller), and then the motor sequence testing is triggering. Motors will start idling
spinning in sequence from No.1 motor to No.8 motor.
Japanese style remote controllers: 1. push the LH stick on the remote controller as
↙ and push the RH stick as ↘, keep them in the position. 2. And then push
sequentially the LH stick as ↖, the RH stick as ↙,the LH stick as ↙, the RH stick as
↘. The left rod sha
ll be maintained at the most left side and the right rod shall be
maintained at the most downward side during you push the sticks. Repeat the 4 stick
nd
pushing actions in the 2
step in sequence, the motor sequence test will be triggered.
Attention: Under normal conditions, motor sequence test can be triggered after one
time stick pushing action . But if the sticks are pushed in wrong positions, the motor
sequence test can only be triggered after repeating the 4 stick pushing actions in step
JIYI Robotics CO. Ltd

2th.
2、Move Direction Test
After the aircraft is armed, the propeller of the aircraft will spin lowly and
steadily in idle speed (power output will be shut down if there is no action in 3s). You
can judge whether the propeller rotates are in reverse direction or not by the remote
controller. For example, when you are pushing the front control stick under the idle
speed, the rear propeller of aircraft should start rotating while the front propeller of
aircraft should stop rotating. Likewise, when you are pushing the left control stick
under the idle speed, the left propeller of aircraft should stop rotating while the right
propeller of aircraft should start rotating.
5.3.5 Fail-safe Protection
Firstly you are required to set the FS protection of remote controller correctly
according to the user’s manual of remote controller.
Setting in the assiatant2 software (path : Base –RC) .When GPS satellite signal is
good, no matter what kind of aircraft is in, FCU will execute automatic
return-to-home if the signal of receiver is lost. If the signal of remote controller is
recovered during return-to-home, switch the flight mode control channel back and
forward to get control right if you want to control aircraft again.
