GuiLin FeiYu Electronic Technology Co., Ltd. was established in August 2007 by co-foun-
ders came from Guilin Electronic and Technology University. We are engaged in develop-
ment, production, and sales of inertial measurement and automatic control electronic
products.
Relying on the rst-class Technology talents, solid technological accumulation and strong
development ability ,we successfully developed a series of inertial measurement tech-
nology, such as AHRS, UAV Autopilot and Aeromodelling Flight Stabilization System .All
the products are widely applied to electronic compass, robot, unmanned aerial vehicles,
ships, model aircraft electronics, as well as real-time attitude determination.

frame arm assembly (seT of 4)
1. Unpack the Arm pairs. Note the arms have different LED colours:
Blue, Red or Green.
2. Unpack these parts to complete 4 arm sets:
1. M3 x 5mm button head screws & M3 x 30mm pillars
2. Four motor mount plates
3. Four motors.
4. Four landing legs (not required for X4 Pro).
Figure 1: Ensure the LED lights are facing outwards during installation:
Note: when tting bolts into the motors and frame support arms, always secure
with threadlock to prevent bolts vibrating loose. Check the tightness of all bolts
regularly.

First attach the motor to the motor plate using four of the
bolts provided. The wires should point out over the ‛Feiyu’
name.
Next bolt 4 x 30mm support pillars to the inside of one arm (5 pillars for the X4 Pro). Insert
the motor plate into the second lowest row of slots on the frame sides and bolt the other
side in place. Make sure LEDs are facing outwards, and the FeiyuTech name is the right
way up.
Ensure all bolts are properly tightened and secured with thread lock.

Please note that the pillars are made of aluminum. Do not over tighten the bolts, or you
may strip the aluminum threads.
We recommend applying a little CA (Super Glue) to the motor slots for additio-
nal stiffness. Use the thin liquid version (not the thick gel version) and place a
small amount on the outside of the joint allowing it to run in.
Do not allow CA to drip onto the motors!

fuselage & soldering The arms
Figure 3: Solder (red arrows) the 4 arms on to the fuselage plate:
Note: the fuselage plate has a side marked “A” and “B”. Ensure side “A” is
always facing upwards.
At this point you must decide which colour LEDs
are going to be in which position on the aircraft.
You are free to arrange the arms by colour howe-
ver you like. The different colours help with visu-
al orientation during ying, so arrange them with
that in mind.
Start using the frame centre plate with the elec-
tronics installed, and facing upwards. Solder all
four arms to this plate. Ensure the arms are rm-
ly clamped when soldering and are at on the
centre plate.
12

Place your soldering iron in the ‛V’ created at the
solder point and melt some solder into it, then
spread it carefully along to get a solid joint.
Caution: Do not overheat the arm
contact points!
Once you have soldered all four arms in place, connect 3S Lipo balance plug to the socket
at the bottom of the fuselage, and the LEDs will light up. You may also check with a DC
meter at the solder point; it should indicate approximately 2.3 Volts.

programme esCs
The next job is to install your ESCs, but before you do this, they need to
be programmed and calibrated to your transmitter throttle.
To do this, you must connect your receiver directly to the ESC, do not
connect through the ight controller. You must also connect the ESC
to a motor, at this stage it doesn‘t matter which motor wire connects to
which.
Caution: Do not install a prop on the motor when programming your ESC!
You will need a LiPo battery to connect to the ESC for programming, and we
recommend it is fully charged as a low voltage may affect the programming pro-
cess.

esC programming – ThroTTle CalibraTion
You must also calibrate all your ESCs to your transmitter throttle. This is necessa-
ry as it is important that each motor combination produces as near as possible
the same output for a particular throttle setting as all the other motors, keeping
them balanced. Instructions are included with the ESCs but we have also inclu-
ded them here.
1. Switch on
transmitter,
move throttle
stick to top
2. Connect
battery pack to
ESC, and wait
for about 2
seconds
3. “Beep-Beep-”
tone emits, me-
ans the throttle
range highest
point has been
correctly conr-
med
4. Move thrott-
le stick to the
bottom, several
“beep-” tones
presents the
quantity of bat-
tery cells
5. A long “Beep-
” tone emits,
means throttle
range lowest
point has been
correctly conr-
med
Caution: Ensure that the throttle endpoints in your Tx are set to +100% and
-100% and there is no throttle curve activated during programming.
Caution: Once all programming has been done, reduce the throttle high end-
point in your Tx to +80%. This is very important, otherwise at full throttle the FC
will not be able to stabilise the machine.
Throttle range setting: Throttle range should be reset whenever a new transmit-
ter is being used
imporTanT noTe on powering The flighT ConTroller
and reCeiver
All the ESCs contain a BEC (Battery Elimination Circuit) which is able to supply power to
the ight controller and receiver. The power is supplied via the black and red wires in the
servo connection lead on the ESC. It is very imporatnt that the system is not powered by
more than one supply, as if the supplies are not balanced, it can cause an overload and
possibly a failure.
16

The best solution for powering the system is to use an external BEC* (not supplied), but if
you don‘t have one you can use the BECs built in to one of the ESCs.
To ensure only a single BEC power source is
supplied to the ight controller, you will need
to disconnect all the red power leads from
the ESCs, except ESC number 1. These can
be discon-nected by removing the red wire
pin from the servo plug. Carefully lift the tiny
platsic clip that holds the pin in place and
slide it out.
By removing the pin this way you should be
able to reinsert the pin again should you ever
need to reprogramme the ESC. Make sure all
loose red wires are carefully insulated!
* If you are using an external BEC, remember to disconnect the red wire from ALL the
ESCs.

insTall esCsand power disTribuTor
After soldering the 4 arms, install the
4 ESCs by connecting the 3 output
wires to the motor wires. At this stage, connect any of
the three wires from the ESC to any wire on the motor,
don’t worry about the motor rotation direction.
Run both the ESC servo leads and the power supply
leads to the middle fuselage.
Connect the power leads to the power splitter lead and
exit the Deans Plug through the bottom frame plate.

insTall frame CenTre plaTe
You can now install the middle frame plate. Take eight M3 x 25mm pil-
lars and bolt them to the underside of the lower frame plate, securing
with thread lock. Before installation, place a small piece of tape on the
underside of the middle frame plate (marked ‛B’) covering the
centre hole (for explanation, see ‛Hover Hold’ in ‛Pre Flight
Checks and Tips’ Section below).
Take the middle frame plate with the letter ‛A’ facing upwards, position plate on top of the
assembly, carefully align the slots with the four arms and slide carefully into position. Hol-
ding the frame plates rmly together, bolt through to the eight frame support pillars. Make
sure all slots are correctly inserted before tightening. Don’t forget to pull the 4 servo leads
from the ESCs out through the middle plate for later connection to the ight controller.
After installing the ESCs and frame centre plate, you can proceed to install the ight con-
troller as per instructions.

insTallaTion Tips for The fyeTeCh fy-91Q
After installing the FY-91Q according to the manual, rst check you have set the correct

FY-91Q).
Dip Switch position for X Type QUADCOPTER:
1 = OFF
2 = OFF
3 = ON
4 = OFF
Dip Switch position for CROSS Type QUADCOPTER:
1 = OFF
2 = OFF
3 = OFF
