FC151 Flight Control System
Instruction Manual
ＦＣ１５１固定翼飞行控制器使用说明书
Packing List
● Mini dimension, MEMS gyroscope and accelerometer in one
chip, only 8 grams
● 32-bit high performance ARM MCU
● Original advanced attitude stabilization algorithm
● Support single/double aileron, fly wing and V-tail aircraft
● Support flaperon mixing
● Support aerobatic/3D airplanes
● Independent sensitivity adjustment of all 3 axes
● Support Futaba S. BUS protocol
● Support mode switch via extra channel, can be switched
between different modes
● Program via button and LEDs
● Support HV inputs
Caution: FC151 will take over all control channels
except throttle, if the setting of FC151 is
inappropriate, it might cause property damage or
personal injury. Please read the caution items and
the rest of this manual carefully before using FC151.
● It's recommended using this gyro on electric powered airplane
models or unpowered glider models
You need an at least 4-channel transmitter. If transmitter only has
4 channels, FC151 will work in auto-level mode by default and
can’t change modes during flight. We recommend you for 5
channel transmitter so that the 5th channel (usually the GEAR
channel) can be used for mode selection.

Thank you for using Dualsky FC151 Flight Control
System. This gyro is equipped with latest MEMS
gyroscope & accelerometer chip, 32-bit MCU and
Dualsky original algorithm. It features at mini
dimensions, high sensitivity and friendly user
interface, more features are listed below:
● FC151 need 2~3 sec start-up time after powered on, please
keep the airplane still during the process
● Servos will only work after the FC151 start-up process ends,
this is normal.
● In auto-level mode, control surfaces of model which is still on
the ground may move to their maximum travel. This is Normal.

● FC151’s heading direction must be the same as airplane
heading direction
● FC151 must be mounted parallel to flight path, otherwise
airplane will yaw.
● FC151 should be installed inside of the airplane, close to the
receiver and CG.
● Install platform must be parallel to horizontal tail, solid
(recommend to use plywood), but do not use servo mount
platform.
● Use accessary double side tape to fix FC151, do not use strap,
patch or 3M Dual-Lock
● Do not wrap FC151 in foam
● FC151 cannot be touched by servo horn, linkage or other
moveable parts
● FC151 must stay away from motor, engine, ESC and batteries
● FC151 cannot be installed outside the airplane, such as wings or
tail

● Input/output signal wires are close to the top of FC151, middle
is VDD and bottom is GND.
● Input signal supports Futaba S.BUS and S.BUS2, only need
single-signal wire to connect SYS and receivers’ SBUS port.
SYS port has higher priority than other input ports. When using
SYS port, other input ports won’t work, transmitter channel
sequence must be the same as following chart:

4. FC151 Power Supply
● V-tail airplane
* V-TAIL
FC151 supports 4.8V-8.4V input voltage, share the same power
with receiver, input voltage should meet the requirements of
receiver, too. Power supply could be battery or ESC.
Set mode switch
Mode select switch is used for select
different flight modes. Please assign a
3-position switch to mode channel and
make sure that channel doesn’t have
other functions. Switch channel pulse
width range should be low
800~1340us, middle 1340~1700us,
high 1700~2200us. If the mode
channel is not connected, the FC151
will work in auto-level mode.

How to setup gains and correction directions?
There are 3 pots to adjust the correction directions and gains for
aileron (roll), elevator (pitch) and rudder (yaw) channel. please
see the sketch below.

● It needs a few testing fly to determine appropriate gains, we
recommend starting from conservative gains (low) first.
● Fly in aerobatic mode at safety altitude, accelerate the airplane
to its maximum speed to see if there is oscillation in pitch, roll or
yaw axis. Oscillation indicates the gain is too high, please slow
down the airplane, decreasing the Gain after landing.
● Please don't change too much gain at one time, We
recommend adjusting 5-10 degrees once.
Ground Test
● Please do a ground test before first flight.
● Test if the mode switch is working properly. Do not turn on the
motor/engine, toggle the mode switch on the transmitter to middle
position, LED2 will turn GREEN for 0.5sec, now FC151 is in
Aerobatic mode.
● Test transmitter moving direction. Move the sticks (except the
throttle) to see if each control surface is working rightly.
● Test gyro correction direction. Rotate the model on each axis,
corresponding control surface should act to against that rotation
(see below). If the action is wrong, please reverse the pot of that
axis.
Trim system
● First please trim model directly on your transmitter in gyro off
mode (do not switch to other modes in trimming). But if
transmitter trim is too large, please zero the trim and adjust the
FC151 Setting
1.How to enter Setting Mode: Turn on the transmitter, move
the throttle to its minimum; power on the model, wait until the L1
green LED ends flashing; Long Press “SET” button (2sec) to
enter Setting Mode. After that, L1 displays the corresponding
SETTING ITEM and L2 shows the corresponding SETTING
VALUE.
Roll & Aileron Movement
Pitch & Elevator Movement
Yaw & Rudder Movement
● There is no need to trim in Aerobatic mode if the model had
been trimmed well in gyro off mode.
● Do not trim in auto level mode, if model attitude in auto level
mode deviate from horizon after series of aerobatic maneuvers,
please switch to aerobatic mode or gyro off mode.
● If model attitude isn't horizontal in auto level mode all the time,
please check and adjust the mounting angle of FC151.
model by changing the length of the linkage between the servo
arm and the control horn.

● Long Press (more than 2 sec) : enter Setting Mode
● Single click in Setting Mode: switch between SETTING ITEM
● Double click (finish within 0.5sec) in Setting Mode: change

请在使用本产品前仔细阅读注意事项和余下章节。
●推荐在电动飞机或无动力滑翔机上使用此系统。
●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。
●自稳模式下，地面上静止的模型的舵面会向某个方向偏
转到最大，这是正常现象。
