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. Check wether the battery power is sufficient, 3S lipo battery when fully loaded voltage is 12.55V. when Start voltage alarm , indicates a
low battery, land and replace the battery
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.
III.Taking off
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.
whether all the four propellers are rotating correctly. If all the propellers work well,
ground. By pushing or pulling the throttle stick, Seraphi can ascend or descend .
2. During flight, Seraphi might suffer side drift or nose rotation. Please use the Yaw 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 to adjust the flying directions.
3. During the flight (flying), watch carefully the flashes of the backlight.
When Low-Voltage Protection is triggered. you
IV. Landing and Locking Motors
1.Pull down the throttle stick gently to descend ,when you find the descent too quick ,pull up the throttle to middle position or above to
reduce the speed . after landing, pull the throttle at lowest position, motors will be locked in 3-5 seconds automatically .
V. Possible Malfunctions and Solutions
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 . 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.
2.Seraphi fly to one direction abnormally
Please do horizontal calibration
NOTE:
1.In any Drop or rollover cases or the first use or did not use it for a long time . You should carry out this step. This will ensure a stable
flight .
2.you should ensure it put on a horizontal ground,do not move seraphi during calibrating.
3 When switching to GPS flight mode, observe seraphi movement ,if it fly to one direction abnormally , switch to Attitude mode
quickly, land aircraft, and carry out Compass calibration , and then try again.
Compass Calibration
Please calibrate the compass in follow cases:
1.When flying on GPS Flight Mode, the aircraft can not hover stably in the air or circles around unusually, or flies aside to one
direction abnormally;
2. When performing fly-home, the aircraft cannot return to the home point.
Tips:Do not Calibrate compass in the environment with Strong magnetics
The compass calibration software can be downloaded from http://www.yunyi-flight.com/data.asp
Unlock the motors
. Push the throttle stick from the middle bottom a little ,then check
should land the aircraft
ASAP.
continue push until Seraphi takes off from the
