Thank you for selecting Dualsky FC130 3-Axis Gyro.
This gyro equipped with latest MEMS gyro chipset,
32-bit MCU and Dualsky original algorithm. It features
at mini dimensions, high sensitivity and friendly user
interface, see more detailed features in below list:

● Original advanced airplane active attitude stabilization algorithm
● Original unique calibration procedure, precisely record mid-point of
each channel, stroke and direction
● Support single/double aileron, fly wing and V-tail aircraft
● Independent sensitivity adjustment of each axis
● Support advanced stability and head locking mode
● Optimized for 3D airplanes
● Support Futaba S. BUS Link
● Support mode switch via extra channel, can switch gyro off or
switch between different mode
● Programmable via button and LED
● Support analog and digital servo, support HS mode, allow full play
of digital servo performance
● Support HV input
Caution - FC130 will take over all control channels
except the throttle channel, if the setting of FC130 is
inappropriate, it might cause property damage or
damage yourself. Please read the caution items and the
rest of this manual carefully before using FC130.
● When install FC130 to new model, the “initial calibration” must be
done, otherwise the FC130 won’t work properly
● During test flight, please connect the “Mode” channel, in case of
the FC130 is not working properly, you can turn it off in time
● After adjust the trim of one channel, please do the “initial
calibration” again
● Recommend to use this gyro on electric powered model airplane or
unpowered model glider
● FC130 can only be used on nitro powered airplane which is
smaller than 70 grade. Too much vibration will effect the gyro, if the
airplane cannot maintain stable attitude, please turn off the gyro
immediately
● FC130 need 2~3 sec start-up time after connect to the power,
please remain the airplane still during this process
● Servos will only work after the FC130 start-up process finished,
this is normal
● Long time standby might cause the gyro “drifting”, it’s recommend
to connect the power to airplane shortly before flight

Packing List Install Instruction
1. FC130 install principal:
- 4 -- 3 -
Radio equipment
You need a 4-channel or higher transmitter. If transmitter only has 4
channels, FC130 will work under Normal Stability by default, cannot
switch mode or switch gyro off during flight. We recommend to use 5
channels or higher transmitter, so CH.5 (usually the GEAR channel)
can be used as switching mode channel.

connect to SYS port on FC130 when using S.BUS link. SYS port has
higher priority than other input ports. When SYS port is using, other
input ports won’t work, transmitter channel sequence must be the
same as following chart:

● FC130 supports 4.8V-8.4V power input, share same power input
with receiver, input power voltage should meet the requirements of
receiver, too. Power supply could be battery or ESC.
Calibration and ground test
1. Test flight the airplane without gyro
Airplane must pass test flight before install the gyro. Make sure all
control surface are working properly, airplane can fly straight (adjust
trim of each channel). Different than multi-copter, each control
surface of airplane has it’s own direction, neutral point and travel(end
point), these settings must be done before install/enable gyro.
2. Gyro calibration
After the test flight is done, the direction, neutral point and stroke of
each control surfaces are fixed, we need to do gyro “initial
calibration”, record these setting data into FC130. If you adjust these
setting after, we recommend you do “initial calibration” again to make
sure FC130 can control the airplane precisely.

Initial Calibration procedure as follow:
1. If transmitter has set dual rate(D/R), please switch to largest rate
2. Turn on transmitter, then connect the power to model
3. Wait LED1 for solid Green
4. Long press (2 sec) SET button on FC130 to enter the Setting
Mode
5. First item of Setting Mode is “initial calibration”, LED1 and LED2
are both solid Blue
6. Double click SET button to start the calibration:
Aileron to left, Green blink, record left travel of aileron
LED 2,Solid Blue Double click SET button,
Blue blink , record neutral point of each channel
LED 2, Solid Green
LED 2, Solid RED Aileron to right, Red blink, record right travel of aileron
LED 2, Solid Yellow
Pull Elevator, Yellow blink, record upper travel of elevator
LED 2, Solid Purple Push Elevator, Purple blink, record lower travel of elevator
LED 2, Solid CyanRudder to left, Cyan blink, record left travel of rudder
LED 2, Solid White Rudder to right, White blink, record right travel of rudder
7. After calibration finished, LED1 and LED2 return to soild Blue
8. Final step, long press (2 sec) SET button to save and exit Setting
Mode
3. Set SW mode switch
Please assign at 3-position switch to SW channel and make sure
this channel doesn’t have other function. Switch channel pulse width
range should be low 900~1300us, middle 1300~1700us, high
1700~2100us. Please refer to the below chart:
1700μs
900μs

H + 100% + 10%
Customizable stability (default: Normal)
M 0% + 10%

L -100% + 10%
Gyro disabled(OFF)
After correct setting, LED2 on FC130 will correspond to 3-position
switch as shown below. If it is not the same, please change the
direction of SW channel.
Caution: When install FC130 to new model, “initial calibration”
must be done, otherwise the unit won’t work properly.
!NOTE：Double click on SET button to skip unused channel

4. Ground Test
● After each “initial calibration”, please do a ground test
● Test if the SW mode switch is working properly. Do not turn on the
motor/engine, toggle the SW mode switch on the transmitter to
middle or high position (Low is gyro off), LED2 will turn Green for 0.5
sec, now FC130 is under Normal Stability.

FC130 Setting
● How to enter Setting Mode: Turn on radio controller, move the
throttle to lowest position; turn on power to the model, wait until the L1
LED finishes flashing Green and then changes to RED (Now the flight
control is in Lock Mode); press the “SET” button on the flight control to
enter Setting Mode. After you enter Setting Mode, L1 displays the
corresponding SETTING ITEM menu attributes (color), and L2
displays the corresponding SETTING VALUE menu attribute (color).

Mode can be changed in FC130 seing
If SW channel is not connected, FC130 will work under Normal
Stability mode by default. This mode can be set in FC130, but it
cannot be turned off. (Not recommended)
● Test gyro moving direction. Move the model on each axis,
corresponded control surface should have excursion the same as
moving direction. If moving direction is different, please run the
“initial calibration” again.
● Test transmitter moving direction. Toggle the stick (except the
throttle) to observe if each control surface moving at correct
direction.
● “SET” Button usage:
1) Long Press (more than 2 sec) under Lock Mode: enter Setting
Mode
2) Single Click under Setting Mode: switch between SETTING ITEM
3) Double Click (finish within 0.5 sec) under Setting Mode: change
SETTING VALUE
4) Long Press (more than 2 sec) under Setting Mode: Save and
Quit to Lock Mode
● Please check the below chart for all settings

Adjust the sensitivity
Different airplane, different flight speed need different Gain. Via 3
potentiometers on the FC130, you can adjust the Gain of each axis
easily. Rotate clockwise will increase the gain, rotate
count-clockwise will decrease the Gain. Please refer to below
diagram.
● Caution: Some settings will take effect after the FC130 is restarted. Cut the power to the FC130 and reconnect after 5 seconds to apply the new settings

AIL ELE RUD
+ - + - + -
● The default Gain of FC130 is suitable for 50 grade EP airplane, if
use on small airplane, Gain might be too low. Please increase Gain
accordingly.
● Correct Gain setting requires test flight to determine, it’s
recommend to use more conservative Gain (low) during test flight.
● At safety altitude, accelerate the airplane to its maximum speed,
observe if there are oscillation in Pitch, Roll and Yaw axis. If there
are oscillation, it indicates the gain is too high, please slow down the
airplane or turn off the gyro, adjust the gain after landing.
● Please do not adjust the Gain too much a time, it’s recommend to
adjust 5-10 degrees a time.
● Gain too low will cause the airplane become blunt, a basic principal
is ---- Gain cannot be too low to decrease the maximum travel of
control surface.
● Some 3D movements require high Gain under low speed, these
kind of Gain is not good for high speed flight. It’s recommend to use
switch to control the Gyro compensate timing.

请在使用本产品前仔细阅读注意事项和余下章节。
● 当FC130被安装到新的模型上时，必须执行“陀螺仪校
准程序”，否则将无法正常工作。
● 新模型试飞，请务必连接Mode通道，以便FC130工作不
正常时关闭陀螺仪功能。
● 当你调整过某通道的微调，行程或方向，请重新执行“
陀螺仪校准程序”。
● 推荐在电动飞机或无动力滑翔机上使用此系统。
● FC130只能用在70级以下油动飞机上。过大的震动可能
会影响系统的工作，如果模型姿态无法稳定，请及时关闭
陀螺仪功能并停止使用。
● 陀螺仪每次上电都有2-3秒初始化过程，请避免这个过
程中模型的晃动。
● 陀螺仪初始化结束后，舵机才会工作，这是正常情况。
● 长时间待机，陀螺仪会漂移，建议飞行前才接通模型电
源。
