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.

6. Assembly Steps – Power Connection and Manually Tilting 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!) Step 3. Connect the JST connectors to the Gimbal Controller Board. Step 4. Name for each end of the Tilt and Roll Controlling Connector.
Step 5. Insert 1-wire End connector of the into the casing of the Phantom. Step 6. 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.
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. Step 4.
Step 5. Step 6. You will use the additional Channel on the back of Or you can add the DJI Phantom Upgrade Kit in the Phantom's transmitter to control the Tilt Axis of GP-35 near future. (This is optional.) 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.
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.
