input power with the receiver, the input voltage must also meet the
requirements of the receiver.

If you are using a 4-channel radio controller, the flight mode can be
set in FC450.
●Set the radio to “Airplane Mode”, turn off all the mixing functions,
set all channel’s D/R to 100%;
●Set all channel’s trim, sub-trim and mechanical trim to “0”;
●Set all channel’s direction according to the below chart;
●Please check the Diagram 6 for corresponding value of channel
direction.
Configuration
●The FC450 needs a 4-channel or higher radio controller to operate;
If you are using a 5-channel or higher radio controller, please sign
a 3-position or 2-position switch on the radio to CH5/GEAR
channel and make sure the switch doesn’t have other function, set
this switch to Low (Switch channel pulse width range should be:
low 900~1300μs, high 1300~2100μs). This channel is used to

ESC Initial Setting
Before install FC450, please finish the ESC initial setting. Make sure
ESCs and FC450 have the same stroke setting.If you use Dualsky ESC,
you can set all ESCs after FC450 installation by the following steps:
●Turn on the radio controller, push the throttle stick to the top, turn
on power to the quadcopter, when L1 shows blue in color, it means
the ESC is in initial setting mode;
●Wait until the ESC's long beep (it means the top point of throttle
has been confirmed), then pull the throttle stick to lowest point;
●Wait about 1 second for a short beep (it means the lowest point of
throttle has also been confirmed), the ESC initial setting is finished;
●Don't move the throttle stick after initial setting, turn the power off
to the quadcopter, then reconnect the power after 5 seconds, the
new setting will be applied.

FC450 Setting
●How to enter Setting Mode: Turn on radio controller, move the
throttle to lowest position; turn on power to the quadcopter, 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).
●“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 chart at the right side for all settings．
Some settings will take effect after the FC450 restarted. Cut the power to the quadcopter and reconnect after 5 seconds to apply the new settings.

Ground Test
●Set all sensitivity potentiometers on FC450 to neutral.
●CH5 is used to adjust flight mode, if you are using it, please toggle
the CH5 switch before flight, L2 LED will indicate the state of the
current switch position: blue indicates low stick input, green
indicates high stick input. Put the CH5 switch to low(auto level
flight mode).
Unlock & Propeller Direction Check
●Make sure your quadcopter's battery is fully charged, and you are
in a wide and flat area;
●Turn on the radio, pull the throttle stick to lowest position, plug in
the power to the quadcopter. L1 LED on FC450 Flight Control will
flash Green (initial startup process), don't move sticks on the radio
controller, keep the quadcopter still. When the L1 LED changes to
Red, it means the initial startup process has finished and the
quadcopter is now in Lock Mode (throttle will not operate). Move
the sticks as shown in the diagram 7 and hold for about 0.5 sec to
unlock the quadcopter. After unlock, motors will reach idle speed
for about 1 sec. If you don't do any stick movements during this
period after "unlock" (5-seconds) the quadcopter will return to Lock
Mode again.

●After unlock, push the throttle a fraction above idle speed, check if
the propellers run in correct direction like shown in below diagram.

●Direction check: Controlling the throttle, make sure the quadcopter
doesn't leave the ground. Slightly move each stick to observe if the
quadcopter moves with your stick input direction. If the direction is
opposite, please change the channel direction on the radio.
Low altitude Test Flight
●After unlock, control throttle to make the quadcopter maintain a 0.5
meter altitude. Observe if the quadcopter is stable. If it’s not stable,
you need to adjust the sensitivity of the FC450.
●The channel center point can differ depending on the choice of
radio brand, the installation of FC450 can also cause deviation. If
the quadcopter has deviation after take off, please adjust the trim
on radio to find the center position.
Adjust the sensitivity
●450 class quadcopter can use the default setting to get a good
flight performance.
●The weight on the quadcopter can differ depending on the choice
of battery. This will impact center of gravity, and the flight
characteristics. To improve flight performance you can address the
below.
●Normally, if the sensitivity is set too high on the “pitch” (elevator)
axis, the opposing axis (i.e., aileron) will vibrate; if the sensitivity is
set too low on the “pitch” (elevator) axis, the opposing axis (i.e.,
aileron) will respond with delay to stick movement.
●If the sensitivity is set too high on the rudder axis it will cause the
motors to over react, which will make the quadcopter unstable in
pitch and yaw direction; if the sensitivity is set too low on the
rudder axis, the quadcopter will have difficulty on tail lock.
●When adjusting the sensitivity, don’t change the setting value too
much, 5-10 degrees a time is enough. When you find a stable
range, then tweak it for optimum performance.
Caution
●Please don’t pull throttle to the lowest position during flight, it might
cause the motor suddenly be stopped and crash the quadcopter.
●When you fly in high maneuvering condition for a long time, the
external acceleration will cause the FC450 cannot maintain a
horizontal status. It’s normal, hovering the quadcopter for few
seconds, FC450 will adjust the quadcopter to complete horizontal.

● F450需要一台四通道或以上的遥控设备；
如果您使用五通道或以上的遥控器，请在遥控器上将
CH5 映射至三段或两段开关，行程设为100%，并确保在
遥控器中该通道没有用作其他功能。开关通道脉宽区间
为：低900-1300μs，高1300-2100μs。该通道用来调节四
旋翼的飞行模式。如果使用四通道遥控器，飞行模式可
在飞控设定项中设定；
● 设定遥控器为固定翼模式，如果遥控器有混控功能，请
关闭所有混控，将各通道行程都设为100%；
● 各通道的电子微调（TRIM或SUBTRIM菜单）和摇杆的机
械微调都归“0”；
● 如下图6所示，根据品牌设定遥控器各通道正反向。

电调行程设定
在安装F450前请设定电调行程，确保您的行程设定是在相
同条件下进行。如果使用双天电调，可以在安装完成后统
一设定电调，具体步骤如下：
● 开启遥控器，将油门推至最高，接通四旋翼飞行器的电
源，L1蓝灯亮时，即进入电调行程设定模式；
● 等待电调发出“滴”声（长声），表明油门最高点已经
确认，此时应立即将油门收至最低；
● 等待约1秒，电调再次发出“滴”声（短声，约0.2秒），
表明油门最低点确认，即完成电调行程设定。电调设定
完成后请勿推高油门（为确保安全，建议设定完成后断
开电源）。
F450设置
● 如何进入设定模式：打开遥控器，油门收至最低，接通
四旋翼飞行器的电源，等待飞控L1绿灯闪烁结束红灯常
亮（此时为锁定状态）后，长按飞控上的“SET”按钮进
入设定模式。此时，L1的颜色指示设定项目，L2的颜色
指示该设定项当前设定值。
● 按键操作说明：
1.锁定状态下长按（大于两秒）：进入设定模式
2.设定状态下单击：改变设定项
3.设定状态下双击（双击有效间隔小于0.5秒）：改变该
项设定值
4.设定状态下长按：保存并退出

● 解锁后，将油门推至略高于怠速，查看螺旋桨旋转方向
是否与图7所示一致。
解锁与螺旋桨方向检查
● 确保您的四旋翼的动力电池电量充足，飞行器四周没有
障碍物；
● 打开遥控器，油门收至最低，接通四旋翼飞行器的电源。
飞控上的L1绿灯闪烁时为飞控初始化过程，此过程中请
勿拨动操纵杆，并保持飞行器静止。L1绿灯闪烁结束红
灯常亮后即进入锁定状态，此时推油门无效。执行图7中
的拨杆动作并保持约0.5秒即可解锁，解锁后电机保持怠
速约一秒。解锁后五秒内如不将油门推高或执行拨杆动
作，飞控将会重新进入锁定状态。
地面测试
● 飞控上的感度电位器都旋至中间。
● CH5通道用于调节飞行模式，如果接入了CH5通道，在飞
行前请拨动CH5通道的开关，观察飞控上的状态指示灯L2
显示是否正确(低：蓝灯，高：绿灯)，初次飞行请将遥
控器上的开关拨至高(自稳飞行)。

● 控制油门，保证飞行器不要离开地面，依次轻微拨动各
通道操纵杆，观察飞行器在地面的倾斜状态与操纵杆的
方向是否一致，如不一致，请在遥控器上更改相应通道
的正反。
调节感度
● 450级四旋翼使用飞控默认电位器感度即可很好的飞行。
● 不同的四旋翼飞行器因为重量、重心、马达和螺旋浆的
不同会导致感度也不同。
● 一般俯仰轴和横滚轴的感度过大会导致在该轴上的震荡；
感度过低会导致在该轴上的动作偏软，突然打杆时飞行
器停止不干脆、难以控制。
● 航向轴的感度过大会导致电机的加减速过于激烈，导致
其他方向上的不稳定；过低则对航向的锁定有影响，打
杆时飞行器停止不干脆。
● 每次感度调节请勿过大，每次旋转电位器5-10度即可，
基本稳定后可继续进行细微调节。
低高度试飞
● 解锁后推油门至飞行器离地约半米，查看飞行是否稳定，
如不稳定，需对飞控进行感度调节。
● 因为各品牌遥控器的中点偏差和飞控的安装偏差，飞行器
起飞后可能会偏向，此时可通过调节遥控器微调将飞行器
调节至理想状态。
注意事项
● 飞行过程中请勿将油门收到底，否则很容易因电机停转
导致摔机。
● 长时间高机动飞行时，由于外加速度影响，导致飞行器
的姿态不能完全水平，此为正常现象，悬停数秒钟后飞
控会恢复水平。
