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.

Step 9. Install the Lower Damper Plate onto the Rear Arm using Black Philip Screws. Pay attention to the installation direction of the Lower Damper Plate. (Apply little amount of Thread Locker when securing screw to metal parts.) Step 10. Complete assembly. Step 11. Insert the cable of the Tilt Motor into the hole of the Roll motor. Step 12. Close view for the wiring of the Tilt motor.
Step 13. Insert 6pcs Rubber Tension Damper Balls into the holes of Top Mounting Frame. Step 14. Complete assembly. Step 15. Install the Top Mounting Frame onto the bottom side of Phantom using 2pcs Silver Philip Screws. (Apply little amount of Thread Locker when securing screw to metal parts.) Step 16. Remove the cover layer of the foam tap on the BL Gimbal Controller.
Step 17. Stick the BL Gimbal Controller board on the Top Mounting Frame and secure it with 4pcs Nylon M3 Nuts. (Tighten the Nylon Nuts completely.) Step 18. Install the Gopro 3 camera onto the Upper Camera cover using the Side Camera Cover and secure it with 2pcs Silver Hex Cap Screw M2.5x6mm. (Apply little amount of Thread Locker when securing screw to metal parts.) Step 19. Complete assembly. Step 20. Connect the gimbal mount with 6pcs Rubber Tension Damper Balls.
Step 21. Insert the Motor Cables of Tilt and Roll Motors into the Connector Cases included. Pay attention to the position of each color of wires. Step 22. Connect the Titl and Roll Motors onto the Gimbal Controller Board. Follow the connect direction as shown above.
5. Assembly Steps – IMU Mounting Step 1. Prepare the IMU Unit. Step 2. Connect one end of the IMU Cable onto the IMU port of the Gimbal Controller Board. Step 3. Step 4. Stick the IMU Unit onto the Upper Camera cover Connect the other end of the IMU Cable into the IMU using double-sided foam tape. Check the double faced unit. adhesive tape regularly to ensure that the IMU is securely positioned. (Ensure the orientation of the IMU is installed correctly.
Step 5. Front view of GP-35 assembly. Step 5. Side view of GP-35 assembly.
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.
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.
