Introduction
The TG20 is a multi-function stabilizer for 360 video shooting, based on our
years of stabilizer development experience, is the most advanced 360 video
shooting stabilization platform to date. The technology built into the TG20 allows
the user easily use and bring world-class movement translation and stability to the
professional cinematographer's market.
TG20 comes with an independent high performance IMU module, no need
work with other controllers, so it can be use on any multi-rotors、drones、cars or
other platforms. High performance motor servo systems with position feedback
and IMU to communicate with our custom 32-bit processor, which processes
movement calculations in 0.001 seconds, this equates to control and stability
accuracy down to 0.01 degrees of translated movements, meaning your images
are going to be perfectly stable in all three axes of movement.
A GoPro power supply system built into TG20, it can be power 10 GoPro
simultaneously, so the customer no need worry about Gopro shooting time. A
buzzer can be generate sound synchronization signal for video post-processing
also comes with the TG20 .

Mounting the Gimbal to the Aircraft
Mounting the Extension Rod
Mounting the extension rod to the gimbal with the M3×12mm screws, fix the
screws tightly to prevent from loosening or dropping.
According to the specific use, one or two extension rod can be used. When
the diagonal size of the aircraft is within 850mm(including propeller size), one
extension rod is ok for use. When the diagonal dimension of the aircraft is above
1140mm, two extension rods needed.
Mounting the Damper Plate
Mounting the damper plate to the another end of the extension rod with the
M3×12mm screws, fix the screws tightly to prevent from loosening or dropping.

The Gimbal Safe Distance
The following figure takes the GoPro 4 as an example. The GoPro settings is:
the viewing angle is widest which is about 170 degrees, video aspect ratio is 4:3,
recording format is 30fps 2.7K or 60fps 1080p.
When there are 8 GoPro vertically mount onto the gimbal and the wide
viewing angle is in 4:3 mode, the minimum vertical safety distance is 30cm, the
viewing overlapping ratio of cameras is about 60%.

When there are 4 GoPro vertically mount onto the gimbal and the wide
viewing angle is in 4:3 mode, the minimum vertical safety distance is 45cm, the
viewing overlapping ratio of cameras is about 10%.
When there are 2 GoPro mount onto the gimbal bottom and the wide viewing
angle is in 4:3 mode, the minimum bottom safety distance is 18cm,the viewing
overlapping ratio of cameras is about 50%.

Pre-Flight Check
Ensure the gimbal is properly installed and attached to the aircraft, and
that the camera is mounted correctly and securely.
Before powering on, spin the gimbal through its complete rotation by
hand on each axis to ensure nothing blocking its movement.
Ensure all cables are connected correctly, without any plugged in
backwards or into the wrong ports.
Verify RC settings and a proper connection between the GCU and the RC
receiver.
Ensure the gimbal has been upgraded to the latest firmware.
Make sure that the gimbal is at horizontal resting before starting.

21 @2016 Accsoon. All Rights Reserved.
Flight Test
1. Make sure all connections and wiring are in good condition.
2.Make sure that the gimbal is at horizontal resting and stable when power-on.
3.After the power is on, the gimbal LED will be green. After 5 seconds, the gimbal
will start automatically, keep horizontal and move to the same direction as the
front of the aircraft.
4.When the gimbal is stationary, it means the initialization is complete and the
gimbal ready to use.
5.Turn on the remote controller ONLY after the gimbal initialized.
6.Toggle the assigned Wroking Modes switch on your TX and make sure it is work
properly.
7.If there is any abnormality after initialization, please refer to the Troubleshooting
section.

Please connect the gimbal and PC with a USB cable and then click "Refresh"
button, when the new COM port comes out, choose the right COM port, click
"Connect".
After success connection the COM port will turn to grey and the status will
display "ReadOK" with a green background which means all settings read out
from the gimbal, also the Firmware revision info displayed.
PC Assistant Menu
Default Settings: Reset all the settings to the factory settings.
Read Settings: Read the settings saved in the gimbal.
Write Settings: After change parameters, the gimbal will not save your
settings unless you write the configuration changes.
Restart: Restart the gimbal.
IMU Live Data
The IMU angles data and real time output chart.
Parameters
The parameters controls the behavior of the gimbal.
Power: This parameter will determine how powerful the gimbal will be in
holding the camera still. Slowly increase this setting until you feel an
oscillation, then reduce the setting until the oscillation subsides. It is
important to check that the setting you have set will not oscillate in any

orientation.
Speed: This parameter will determine how quickly the gimbal back to the
original position when it is not there due to any external force. Slowly increase
this setting meanwhile drag the axis to make it return to the original
position, until the gimbal back to the original position quickly and without
any vibration.
Trim: This parameter offers accuracy compensation when the gimbal is
working in dynamic, such as frequent vibrating in all direction or moving.
When the value is too high the gimbal will oscillate, then the value should
be decreased properly.
NOTE: Firstly adjust the power value, then the speed value and finally the trim
value.
Follow Deadband: Flollow deadband defines a range in degrees of handle or
aircraft movement which will be ignored. In practice, this means that you can
move the handle less than the deadband and the camera will not pan. Once
you exceed the pan follow deadband threshold, the camera will begin to pan.
Follow Speed: This parameter means how fast the gimbal follow the aircraft
or handle movements.
Working Mode
Pan Follow: The gimbal pan axis always tracks the aircraft or handle
orientation, which means when the aircraft or the handle rotated left or right,

the camera will move, smoothly following the aircraft or the handle rotation,
and stop at the appropriate angle.
Pan Lock: All three axes are in self-stabilized and the direction is locked.
Calibration
Gyro Cali: When you want to perform gyro calibration, click "Motor Off"
button and the gimbal will standby, then you keep the gimbal stationary
without any movement or vibration and click "Gyro Cali" button. The
calibration will complete in 10 seconds.
NOTE: Before doing calibration, please ensure that the temperature shows
"NORMAL" .
Pan ORNT Cali: You can change the pan axis original orientation by use the
"Pan ORNT Cali". Lets the gimbal in standby by click "standby" button, then
drag the pan axis to the orientation you wanted and then click "Pan ORNT
Cali", the gimbal will save new orientation.
Motor Switch
Motor Off: Click this button turn the motor off, the gimbal will go to standby.
NOTE: All calibrations can only be performed after the motor is turned off.
Motor On: Click this button turn the motor on and the gimbal will hold the
camera stable.

Troubleshooting
NO. The Problem The Cause What to DO
1 The gimbal keeps
drifting after
initialization.
(1)The TX trims are too
high
(2)The ambient
temperature is too low
(1)Adjust the TX trims
(2)Wait for 1 to 2 minutes to
make the IMU warm
2 Some axis can not
keep horizontal after
initialization
(1)The default
calibration is wrong
(2)There is drift in gyro
(1) Do gyro calibration by
PC Assistant software or do
an offline gyro calibration
by RC
(2)Please contact Accsoon
customer Service if it still
cannot keep horizontal or it
moves irregularly after
initialization
3 The gimbal cannot
keep horizontal after
initial power on if the
ambient temperature
is lower than 10
degree
(1)The IMU wram up
time isn't enough
(1)Warm the gimbal for 2 to
3 minutes and wait until it
goes almost horizontally,
then quickly power off the
gimbal and power on it
