Adjusting the gimbal parameters (GBL-T3)
Airpeak gimbal
setting guide
Correct adjustment of the gimbal is essential for proper use. Please review the
following explanation and make any necessary changes to the gimbal’s settings.
Please refer to Help Guide for the instructions on how to mount and use
the gimbal.
Preset of motor parameters ..................................................... 2
Important note: Be sure to do this before using the gimbal.
To use the gimbal correctly, you need to enter the appropriate motor
parameters for your camera and lens. This section describes how to apply
motor control presets all at once.
Manual adjustment of motor parameters ............................ 3
If the motor parameters of the gimbal do not match due to the dierence
in weight when the camera is equipped with accessories (such as a hood,
a filter, etc.) or the individual dierences in the gimbal, you need to manually
adjust the motor parameters. This section will teach you how to do this.
Calibration .................................................................................... 13
Normally, it is not necessary to do this calibration. Only do this if you
experience symptoms of drift, such as if the camera cannot be leveled,
if the angle gradually shifts, etc. Follow these steps to execute Gyro
calibration of the IMU sensor.

Preset of motor parameters
1. How to input motor parameters with Airpeak Flight
1Tap “Settings“ at the top right of the Airpeak Flight app screen.
2Tap [Gimbal] from the displayed setting menu.
3Tap [Main Tuning] to display the parameter setting screen for motor control.
4Each parameter value can be changed by moving the slide bar or tapping the value on the
right side and entering the value via the on-screen keyboard that is displayed.
2. Apply preset at once
1Tap “Settings” at the top right of the
Airpeak Flight app screen.
2Tap [Gimbal] from the displayed setting menu.
3Tap [Main Tuning] to display the parameter
setting screen for motor control.
4Tap [Start] in [Apply a preset] menu at the
top of the motor parameter setting screen.
5Select a camera and lens and apply motor
parameter presets.
Once applying preset has been done, refer
to Trouble Shooting in Manual adjustment
of motor parameters section as needed.

Note: The preset values of the motor parameters are
the values under the condition without a lens hood,
and with a filter attached.
Check “Compatibility” to know the camera body
and lens supported by this product.

Preset of motor parameters 2
If the motor parameters of the gimbal do not match due to the dierence in
weight when the camera is equipped with accessories (such as a hood, a filter,
etc.) or the individual dierences in the gimbal, you need to manually adjust
the motor parameters.
Please install PC software “gTuneDesktop” by Gremsy for motor parameters
adjustment.

1. About motor parameters
Stiffness
It is a parameter to control the horizontal stability
of gimbal. (Min: 0` Max: 255)
A higher value causes gimbal oscillation, while a
lower value causes decreased stability.
*This value varies depending on the model of
camera and lens used.
Gyro Filter, Output Filter
It is a parameter to control the eect on gimbal
oscillation control. (Min: 0` Max: 10)
A higher value can suppress oscillation but will
sacrifice horizontal stability.
Hold Strength
It is a parameter to control the holding strength
of gimbal position. (Min: 0` Max: 100)
The gimbal can hold the position with a higher
value, but oscillation will occur.
Gain
It is a parameter to control the speed of gimbal
returning to horizontal. (Min: 0` Max: 255)
The gimbal can be leveled quickly with a higher
value, but oscillation will occur.

2. Connect gimbal to PC
1Before motor parameter adjustment, please double check the gimbal is properly balanced.
If it is not balanced, refer to Startup Guide or Help Guide and try the balance adjustment again.
2Control cable needs to be disconnected during motor parameter adjustment. With the power
source of Airpeak turned o, disconnect one side of the control cable as shown in the image below.

4. Adjust motor parameters on each axis
Adjust the motor parameters on each axis in the following order to get a proper response without any
overshoot on the graph: TILT ROLL PAN
1Check the graph.
A. Press the [MONITOR] button to switch to the MONITOR screen.
B. Press the arrow button on the right side of the MONITOR screen to renew the graph.

2TILT axis parameter adjustment.
A. While holding the gimbal so that it doesn’t roll, push the TILT axis of the gimbal directly
by hand and move it up to +10 degrees (Angle of the TILT axis will be displayed at the top of
BASIC setting screen).
B. Quickly release your hand from the gimbal.
C. If an overshoot happens, increase the TILT value on the SETTINGS screen and move the
TILT axis +10 degrees again then check if the overshoot is eliminated (The recommended
incremental value is around 5).
D. Repeat steps B – C until there is no overshoot. Search for the minimum value, as gimbal
oscillation will occur when the value is too high.
E. Do the same sequence with the opposite direction (-10 degree) and set the TILT value.

Hint: In the left figure below, there is no overshoot in the positive direction, but there is in the
negative direction. Increase the TILT value to eliminate the overshoot in both direction as shown
in the figure on the right.
