Align 3GX V2.1 Setup

Swashplate Settings
Enter Setup Mode Turn on transmitter, press/hold SET, power on
heli, release SET before LEDs stop scrolling.
Setting 1 LED LED1 Lit
Setting Mechanical Travel and Neutral point setting
Setup Method 1.Servo on right side of heli frame is AIL, middle is
ELE, left side is PIT. Do not exchange AIL and PIT
connections, otherwise some compensation
feature may be reversed.
2.Confirm proper swashplate action with PIT, AIL,
and ELE commands.
3. If incorrect movements or servo has no
movement, please check servo connection to 3GX
as well as radio control system.
4. Adjust the maximum collective pitch using the
transmitter's swashplate mixing function (pitch
swash AFR). Do not adjust individual servos
endpoints through the servo ATV/AFR function.
Should any changes made to the endpoints or
subtrims on the transmitter in the future, the 3GX
flybarless system initial setup must be performed
again.

Speed Governor Settings
The 3GX needs to know the maximum and minimum positions of
the throttle and mechanical travel range, you have to set this
function whether you use it or not. Note: Swashplate settings
need to be completed and then set the governor function.
1. Reset throttle curve and pitch curve to default 0‐50‐100.
2. Confirm the transmitter is powered up, and throttle stick is at
lowest position.
3. Press and hold the SET button while powering up the receiver
until all 1~5 LED lights up. Release the SET button and GOV red
LED will light up.
4. Push the throttle stick on transmitter to the maximum top, and
in a few moments LED will go off and system power cycles,
indicating the completion of setup process.
LED1~5 all lit up
Speed governor setup
1. Ensure correct throttle servo direction and mechanical travel
range prior to connecting the governor.
2. Connect wires and install sensor magnet as shown in diagram.
3. When using standard parallel channel layout or S.BUS system to
connect the 3GX, speed setting is done through channel 7.
Turning channel 7 on or off will enable or disable governor
function. When satellite receivers are used, governor speed
setting is done through channel 5.
4. 3GX GOV LED will lit green when governor is active, red when
inactive.
5. 3GX throttle governor has throttle safety built in. If throttle
isn't lowered to minimum during 3GX startup, governor function
will not activate. Restart the 3GX with throttle lowered all the
way down.
6. The following two requirements must be met in order for
governor to activate:
(1) Governor switched on.
(2) Throttle position is at 30% or higher.

Rudder Settings
1. Push and hold the SET button for 2 second to enter the
rudder gyro setup mode while 3GX is turned on.
2. Each setting value is labeled on the 3GX control unit with
either green or red lettering, which corresponds to the STATUS
LED color. Subsequent setup mode is entered by a single press
of the SET button. Setup mode will exit if no activity is detected
in 10 seconds.
Wide/narrow servo band setting
1. 3GX Flybarless system is compatible with both the 760μs
narrow frame rate servos (such as Futaba S9256, S9251,
BLS251), as well as the standard 1520μs frame rate servos
(most others). Proper frame rate must be selected based on
your servo's specifications.
2. Push the ransmitter rudder stick left or right to select the
frame rate. For example, if rudder is pushed to the left (or
right) and STATUS LED turns green, the frame rate is set to
1520μs. To set it to 760μs, the rudder stick need to be pushed
from the center to the opposing end 3 times for the STATUS
LED to turn red, indic ating frame rate set to 760μs.
Flight Mode Setting
1.With 3GX in operation mode, push rudder to left or right, and
press the SET button for about a second.
2.After entering setting mode, the STATUS LED will flash specific
number of times to indicate specific settings.
3.During setting process, LED 1 to 5 indicate the rate of setting;
flashing LED represents 10%, while steady lit LED represents 20%.
For example, if LED 1 and LED2 are steady lit with LED3 flashing,
the set rate is 2*20+10=50%.
STATUS flashes green once
Cyclic pitch speed adjustment.
1. After entering setting mode, STATUS LED flashes once.
2. Aileron and elevator rate can be adjusted independently.
3. Moving the aileron stick will display aileron roll rate on the LED.
The more LEDs, the faster the roll rate. Moving the aileron stick
can increase or decrease the number of LEDs that lights up
between LED1 to LED5, which sets the aileron roll rate. Same
method is used to adjust the elevator flip rate when elevator stick
is moved.
4. Elevator flip rate is adjusted based on aileron roll rate. When
the difference between elevator flip rate and aileron roll rate
differs by 20% or more, 3GX will automatically adjust until the
error rate falls within range. Therefore, we recommend
adjustment aileron roll rate first, and then adjust elevator flip rate.
5 .Moving the related control stick, LED will automatically jump to
the set rate display of the specific stick function. For example,
moving the aileron stick, LED1 to LED5 will display aileron set rate.
Moving elevator stick, LED to LED5 will display elevator set rate.
