1. Introduction:
Brushless Gimbal is the next generation technology for high quality aerial photography. Senrigan GP-35
Brushless Gimbal is driven directly with two Brushless Motors for two axis movement roll and tilt without
gears or belts. The main advantages of this design compared to traditional actuators (servos) are the Brushless
Gimbals have no backlash in the gear or belt, and it provides the instantaneous response to the disturbance. Due
to lack of gears/ belts, this new Brushless Gimbal is extrenely easy to install and with low weight which is
perfect for aerial activities. The lower the weight, the longer the flying time you can achieve.
Differ than others, the motors and Gimbal Controller of Senrigan GP-35 Brushless Gimbal have been well test
and tuned of the PID parameter for GoPro 3 Cameras in the factory before selling. So no worries about the
setting or PID tuning of the Brushless Gimbal. Furthermore, GP-35 is designed to full fit DJI Phantom
Quadcopter with only two screws easily. There is no modification needed at all when using with GP-35. So this
is suitable for both beginners as well as professionals.
Last but not the least, GP-35 Gimbal comes with an AV Output cable which allows GoPro 3 camera to transmit
the video signal down to the ground by using an FPV system(not included). So that you will see what you are
exactly recording. At the same time, GP-35 has the newer Brushless Gimbal firmware installed which enable 90
degree tilting. This is very useful for professional aerial filming and FPV flying activities.
Features:
-Direct drive of Brushless Motors for both Roll and Tilt axis.
-Full fit to DJI Phantom Quadcopter without any modification.
-Simple and strong Mechanism Design.

Step 1.
Take off the Top cover of your Phantom. Please refer
to the manual of DJI Phantom.
Make sure the Power cable in the Phantom is passing
through the casing.
Step 2.
Solder the Male JST Connector to the Power cable of
the Phantom. (Important: Solder Red to red wire, and
black to brown wire!)

Insert the 1-wire End connector into F2 port of NAZA
controller in the Phantom. (Pay attention to the
position (use the Lowest Pin) of the connector.)
Step 7.
Please be noted that the 3-wire End connector is
useless when using the original Transmitter of
Phantom. You can just fix this connector on the
landing gear of Phantom for better appearance.
Step 8.
Connect the 4-wire End connector to the Gimbal
Controller Board. (Pay attention to the direction.)
Cover the Top Casing back to Phantom and now is
ready to setup the Gimbal Tilt control with the
Assistance Software of Phantom (NAZA).

7. Assembly Steps – Setup Manual Tilting on NAZA
Step 1.
Turn on the Transmitter and then power on the
Phantom. Then connect Phantom to the computer with
DJI Assistance Software. (For more details, please
refer to the manual of your Phantom.)
Step 2.
You can take this Gain values as reference if needed.
(You may need to adjust these values according to
your own situation.) The value of Pitch and Roll gain
must be lower than 110 so that the gimbal will work
with minimum vibration.
Step 3.
Setup the Gimbal function of your Phantom as shown
above as to control the Tilt axis of GP-35 Gimbal with
original Phantom Transmitter.
Step 4.
This is for reference only. (You can adjust these values
according to your own situation.)
Page 16 of 19
Step 5.
You will use the additional Channel on the back of
Phantom's transmitter to control the Tilt Axis of GP-35
Gimbal. You can use or DIY a flat rod to control this
channel, or you can order the DJI Phantom Upgrade
Kit in the near future.
Step 6.
Or you can add the DJI Phantom Upgrade Kit in the
near future. (This is optional.)

8. Power On Steps
Before Power On the Gimbal:
1. Please check the polarity of the JST connectors.
2. Make sure the IMU is installed on top of the Upper Camera Cover correctly.
Refer to IMU Mounting section.
3. Use only 3S 11.1V Lipo Battery for your Phantom.
4. The Brushless Gimbal Controller has been tuned perfectly to plug-n-play with GoPro 3 camera on
Phantom.There is no additional tuning needed.
Follow the following sequencies to power on your Senrigan-GP-35 Brushless Gimbal correctly.
Step 1.
Turn on your Phantom's Trnsmitter.
Step 2.
Power on the Phantom with 3S 11.1V Lipo Battery. Keep the whole machine steady when power on and wait
for around 5 seconds for the Phantom and the Gimbal to performance the initialization.
Step 3.
If the initialization step is successful, GP-35 Gimabl will level the Gopro 3 Camera slowly for both Tilt and
Roll axis. Otherwise power cycle the system and try again.
Step 4.
Ready to go.

10. Troubleshooting
Q1: Why does the gimbal not stabilize the camera?
A: Please refer to installation and make sure the IMU Unit is installed at right orientation and the motors
are connected to the right pins.
Q2: Why is the gimbal shaking?
A: Usually it is caused be wrong IMU facing, please make sure it is facing down. Refer to IMU Mounting
section.
Q3. Why is the captured video shaking?
A: Please ensure your Aircraft is well turned with minimum vibration before mounting the Gimbal. Sometimes
you may need to balance the props for your Aircraft too.
Q4: Do I need to upgrade to latest version of firmware or adjust any parameters?
A: It is not necessary to upgrade the firmware or adjust any parameters unless further instruction is given. The
Brushless Gimbal Controller is well tuned to plug-n-play with GoPro 3 Camera on Phantom to give the best
performance.
Q5: Where can I get more help for this product?
A: Please contact our distributors/ dealers for warranty and customer service.
