LEDs and Low-Voltage Alert
LEDs and Low-Voltage Alert
The red LEDs (LED1, LED2) indicate the forward direction of the aircraft.
The green LEDs (LED3, LED4) indicate the backward direction of the aircraft.
The LED5 is the back light of the aircraft.
Low-Voltage Protection:
1.During flight, when the back light turn (ourdoor with enough GPS signal), this
indicates battery voltage is low, and you should land the aircraft ASAP
2. During the flight when the back light flash (indoor with no GPS signal) quickly
,this indicates battery voltage is very low and you should land the aircraft ASAP
Otherwise, the aircraft is more likely to crash due to lack of power.
Usage of Battery and Charger
1. Before charging, please check carefully the battery charging terminal and the
charger socket. Be sure the convex side of the terminal faces upwards and the front of
the charger faces upwards too. Carefully plug the terminal in the charger socket. DO
NOT stubbornly plug the wrong side of the terminal into the charger socket so as to
damage the charger.

I.Flying warnings
1. For the first flying, beginners are strongly suggested taking necessary trainings by professionals or doing some pre-
exercises on simulators until you can skillfully operate the aircraft or the simulator and the remote controller
2. During flying, please make sure that Seraphi is always within sight and its back light always faces its operator so that he
could determine its flight attitude and adjust its flight directions when necessary.
3. During flying, what's more, please watch the flash of back light at any time and keep alert to Low-Voltage signals. Low-
Voltage Alert is to indicate that the battery cannot provide enough power for the aircraft and to warn you to land it is triggered
the aircraft to avoid or reduce crashes or other harmful consequences. ASAP
4. Sensors in the heart of SeraphI are damageable, so be sure not to hit or drop the aircraft heavily. Otherwise, the inertial
measuring unit (IMU) might be destroyed. If Seraphi flies in an abnormal way after being hit or dropped Seriously, please
return it to Yunyi-Flight to repair immediately.
Propeller Installation
The direction of the arrow on each propeller
indicates the rotation direction of the propeller
and the motor. Mount each propeller on the
corresponding motor with the same arrow. BE
SURE that the side with the arrow on each
propeller faces the sky. DO Not mount it
upside-down. Then screw down each nut.

II. Preparations for Flying
1. Before flying, please check whether the aircraft is in good condition , whether the rotation direction of all
the propellers are right, whether the motors and propellers are fixed well. Overload is strictly prohibited and
the maximum load is about 1.3kg.
2. Power on Seraphi and if back light flashes this indicate it is normal ,then it flashes slowly,this
indicate it find GPS (outdoor ), it can remember home point,if it Always flashes this indicate it
can not find GPS ( indoor or you can fly in attitude flight mode, weak GPS signal),
3. Be sure to observe the surroundings before flying. Choose an open space without obstruction and tall
buildings as flying field. Stay away from crowds, especially children. Place the aircraft over 4 meters away
from you and others to avoid accidental injuries.
4、we suggest the operator choose an open space without crowds and tall buildings as flying field. Safety
comes first. Be Sure to protect your eyes and other vulnerable parts of your body. We strongly suggest you
wear an eye shield to protect your eyes.
1. Make clear the nose and tail of the aircraft and make sure the back light of the aircraft faces towards the
operator. Switch on the remote controller, then power on the aircraft. waiting backligh ashes t fl or
(gps signal enough) and then release the right stick and keep it at the mid point ,Unlock and start the motors
in a natural state. Push the throttle stick (left stick) from the middle bottom ,then check whether all the four
propellers are rotating correctly. If all the propellers work well, contiune push until Seraphi takes off from
the ground. By pushing or pulling the throttle stick, Seraphi can ascend or descend in the air.
2. During flight, Seraphi might suffer side drift or nose rotation. Please use the Yaw stick (left stick) to adjust
the back light direction and keep it facing towards the operator. Make sure the aircraft and the transmitter
are in the same frame of reference and pull or push the roll and pitch stick (right stick) to adjust the flying
directions.
3.During the flight, you can switch to GPS Flight Mode(make sure GPS signal enough)
III.Taking off
Compass Calibration
The GPS module has a magnetic field sensor inside
for measuring the geomagnetic field, which is not the
same in different areas.
Calibrate the compass before the first flight or
when flying in a different area. Make sure to keep
away from ferromagnetic substance and other
electronic equipment when calibrating or flying.
If the calibration was successful, calibration mode will
exit automatically.
Please download the Operating Instructions and
software from the website (www.yunyi-flight.com)

1.When landing Seraphi, please carefully pull the left stick down slowly to lower the throttle little by little so
that the aircraft could land safely. If the aircraft falls too fast, please raise the throttle a bit in order to slow
down its falling speed. During landing, please always keep an eye on the flight height and flight movement.
Adjust the aircraft' position by slightly pulling or pushing the right stick so that the aircraft could land on the
desired destination. DO Not pull the throttle stick to the bottom quickly before you haven't landed the
aircraft completely on the ground, otherwise, the aircraft might suffer a rollover.
2.Slowly Pull the throttle stick (left stick) to the mid bottom point to land aircraft ,after Seraphi has
completely landed, .Lock and stop motors
1.Abnormal rotation of propellers
You have executed Unlock Motors procedure, but the aircraft abnormally shakes and the propellers won't
rotate. We advise you to lock and stop the motors and then unlock and restart them. Try again until the
propellers could rotate well. In case the propellers still can not rotate, have a try to push a propeller by hand
to aid its rotation. If they keep still again, please return the aircraft to Yunyi Flight to repair.
