After mounting the Orbit anti-vibration plate to the yaw motor, connect the gimbal to your multirotor frame. For
this you can use 12mm aluminum tube clamps (recommended).
6. GIMBAL BALANCING
Satisfactory stabilization performance is possible only with a properly balanced gimbal. In order to balance your gimbal
in all 3 axes, follow the rules below:
1. Mount the gimbal on your multirotor - it is crucial for a proper balancing and tuning process.
2. Put your multirotor on a stable, level surface.
3. Mount your camera with lens, battery, SD card etc. on the gimbal camera shelf –Photo 1.
a) With your camera mounted on the shelf, find a place where a camera shelf remains levelled to the ground.
4. Unscrew a little thumbscrews to balance the pitch axis - Photo 2.
b) First move bottom bar to find balance position then by moving top bar firmly secure camera , find a place
where a camera can stay put in every position of the pitch axis (e.g. rotate camera by 30 / 60/90 degrees,
if it stays in every position, balancing is made properly).
c) Once camera is properly balanced place upper support above camera hot shoe. Remove blind/cover from
hot shoe and in that place slide in bottom plate of support. Make sure that screws are properly tighten. –

5. Unscrew little thumbscrew to balance the roll axis.
a) By moving camera box to the left and to the right, find a place where a camera can stay put in every position
of the roll axis (e.g. rotate a camera by 10 / 20/30 degrees, if it stays in every position, balancing is made
properly) –Photo 4.
6. Unscrew a little thumbscrew to balance the yaw axis.
a) Tilt your multirotor frame by 20 degrees (left/right or forward/backward)
b) Hold the gimbal by thumbscrews under the yaw motor. By moving gimbal back and forth, find a place where
a gimbal can stay put in every position of the yaw axis (e.g. rotate a camera by 20 / 30/45 degrees, if it
remains put in every position, the balancing process was conducted properly) –Photo 5.
7. Make sure that all thumbscrews and screws are tighten properly.

7. ALEXMOS CONTROLLER
InfinityMR-S2 is equipped with a well-known AlexMos controller. It is advised that you will get to know AlexMos controller
manual before using the InfinityMR-S2 gimbal. HD Air Studio does not take responsibility for damages of a product caused
by the ignorance of AlexMos manual.
Each InfinityMR-S2 gimbal is running on a specially licensed firmware that enables the application of encoders. Every
AlexMos board has its unique serial number. In case of damaging a AlexMos controller, it is possible to transfer your
encoder license to another controller, but only after reporting the serial number to www.basecamelectronics.com.
All information about AlexMos controller can be found
here: www.basecamelectronics.com

8. GETTING STARTED
1. With a camera installed on the gimbal, connect the battery to the gimbal (red JST power plug). HD Air Studio
recommends to use a fully charged 4S LiPo battery as power source. 1
2. Make sure that your gimbal can freely rotate in all axes.
3. Switch on the gimbal by using a power switch.
4. Gimbal will turn on within 1-2 seconds and it is ready to use.
5. Gimbal by default is set to follow mode in the yaw axis (it will follow multirotor move in yaw/pan axis). In order
to change that, please refer to AlexMos Controller manual available at www.basecamelectronics.com
6. Gimbal by default can be operated via a standard PWM signal in two axes: pitch/tilt and yaw/pan. To control
those two axis, connect your radio control receiver by using two cables coming out the gimbal (RC_PITCH and
RC_YAW). RC_YAW cable has 3 wires: white - signal; red - 5V; black –ground. You can use this cable to power
your radio control receiver. RC_PITCH cable is only one wire: white –signal.
Connection Scheme
9. CHANGING ALEXMOS CONTROLLER DEAFAULT SETTINGS
1. Download AlexMos latest GUI configurator form www.basecamelectronics.com web site.
2. Make sure you have installed all necessary drivers on your PC/MAC.

3. Open AlexMos GUI configurator.
4. Make sure that a camera is properly installed on the gimbal. Gimbal has to be installed on a multirotor/drone
frame.
5. Connect USB cable to InfinityMR-S2 Gimbal.
6. Power on the gimbal.
7. Connect USB cable to PC/MAC
8. Choose proper USB port from the list available on GUI configurator and press „Connect” button.
9. Now you can change all settings of AlexMos controller.
10. NOTE: To change any setting of AlexMos controller refer to the manual available at
www.basecamelectronics.com
11. HD Air Studio recommends not to change any settings in „Encoders” tab without good knowledge of AlexMos
controller manual.
14S 1000mah Lipo battery allows to use a gimbal for 35-90min depending on the camera weight.
10. USING PPM-SUM, FUTABA S-BUS OR DSM2/DSMX RECEIVER
1. To enable the operation of all 3 axes and launch additional features available on AlexMos controller, you can use
PPM-SUM, Futaba S-BUS and DSM2/DSMX signal receivers. Connect your receiver using RC_PITCH cable (white
wire is a signal wire and should be connected to PPM-SUM, Futaba S-BUS, DSM2/DSMX signal port on your
receiver). To power your receiver you can use RC_YAW cable.
2. Open AlexMos GUI configurator and connect USB cable to the gimbal and PC/MAC.
3. Go to „RC” tab in AlexMos GUI configurator.
4. In „Input Mapping” section change „RC_ROLL pin mode” to desired PPM-SUM; Fustaba S-BUS or DSM2/DSMX
connection type.
5. Now you can choose any radio control virtual channel for each feature you want to enable.
E.g. If you use Futaba S-BUS, you need to select „Futaba s-bus RC_ROLL pin mode”. To operate the ROLL
axis you can use RC_VIRT_CH_9; to operate the PITCH axis you can use RC_VIRT_CH_10 and to operate the
YAW axis you can use RC_VIRT_CH_11. To operate CMD you can use RC_VIRT_CH_12. 

6. After all changes are introduced, press „Write” to save the settings.

11. TIPS FOR TUNING THE ALEXMOS CONTROLLER WITH ENCODERS
1. For a proper tuning of InfinityMR-S2 gimbal please refer to the AlexMos controller manual.
2. Make sure that encoders are calibrated properly. Remember - for tuning encoders you don’t need a very good
stabilization, big precision is not required. When gimbal is balanced, encoders calibrated, power source
connected and powers for motors set, you can enable auto-tuning. Firstly, run auto-tuning for all axes together
(the slider should be placed in the middle of scale). After that you can run auto-tuning for each axis separately
(start with the pitch, than roll, at the end yaw axis).
3. Any tuning of a gimbal should be conducted with a gimbal mounted to your multirotor with full equipment
installed on the gimbal (camera, battery, video, RC).
4. If after auto-tuning, you can still see some small jitters or buzzing it means you might need some manual tweaks
of PID values. It is good to refer to AlexMos manual. Notch filters might help to get rid of vibrations.
5. If you notice some problems with a drifting horizon, it is advisable to calibrate the temperature for IMUs. Again,
refer to the AlexMos manual. You can also try to set “gyro trust” to 140-160 (that will work just with encoders
enabled).
6. If is recommended to use lens support. If you have an option to use a lens that can be clamped with lens support
that will make the whole camera shelf even more rigid and will help in the tuning process.
