Alwarerc Senrigan GP-25 Lite Brushless Gimbal - Manual (Page 17)

7. CG Adjustment
Step 1.
After the assembly, you will need to check the balance
point of the GP-25 with camera mounted on it as to
obtain the best performance. Step 2.
Two axis (horizontal and vertical) can be adjusted with
two screws.
Step 3.
Use the closer slots when mounting with Gopro3 Cam. Step 4.
Use the outer slots when mounting with Gopro2 Cam.
Step 5.
With the camera mounted on the gimbal, the camera
must be steady at horizontal, roll +- 45 degree, tilt +-
45 degree when the CG is good. Otherwise go back to
step 4. to adjust the correct CG.
* This is very important for stable performance.
