1.0 Manual
G-2D Gimbal is a high-precision and portable Gimbal specifically designed for iLook, iLook+, GoPro series cameras by Walkera. Adopting aluminum alloy CNC precision machining , brushless motor drive, high accuracy intelligent electronic control system, it can be widely applied to film photography, advertising aerial photography etc

. The highly precise and stable structure can ensure the aircraft accurately control the mounted camera to keep stable during high-speed flying and take the best aerial photography pictures and videos. 

### 2.0 Installation Instructions (1) Use hexagon socket head screw(M3x8) to fix the Gimbal fixture underthe fuselage. (2) Use hexagon socket head screw(M2x3.5) to fix the Gimbal under the mounting bracket.

# Balance Note: (1) When Gimbal is assembled with camera and meet the 

# 1....--l} Accessory Gimbal barycenter is unbalanced, assemble Gimbal Balance Accessory is necessary. (2) Please make sure the Gimbal equipped with camera before

power on, otherwise it will effect the accuracy in calibration.

### (1) Stick position mode means adjust tilt and roll angle through transmitter tilt and roll stick. Turning switch**$J~1)** to 1 position, the tilt and roll angle will be changed in corresponding to the tilt and roll stick input, take the mid-position as start position, the more you put tilt and roll stick, the more the gimbal tilt and roll angle be changed and vice versa. The gimbal till and roll angle will 

### be 0" when the tilt and roll stick at the mid-point. (2) Stick rate mode means adjust till and roll change rate through transmitter tilt and roll slick. Turning switch ( o**~1)** to 0 position, the till and roll change rate will 

### be changed in corresponding to the lilt and roll stick input, take the mid-position as start position, the mons you put tilt and roll stick, the more the gimbal till and roll change rate be changed and vice versa. The gimbal tilt and roll rate will be 0 when the tilt and roll stick at the mid-point. Remark: When using transmitter knob adjust the gimbal till and rolling, suggest adopt the position mode(slide the switch to 1 position), same as the transmitterslick.

(4) Press FN key triple until Green LED keeps solid, adjusting parameters will be saved and exit PAM. Principle ofTilt Motor Output Power and Gain Control Adjusting: Underthe same load status, the tilt motor gain should decrease when you increase the output power while you can increase the lilt motor gain when the output power decreased. Therefore, you can get more tilt motor gain by decreasing the output power while the output power is enough to make the G-2D more stable. However, the G-2D anti-shaking abilitywill decrease either when you decrease the motor power. 7
