IMPORTANT: The first couple of flights, you may expereince the
aircraft drifting,
This is normal, please continue to fly the aircraft manually, while the
system inprove the calibration, after 5-10 minutes land, lock the motors,
this will save the improved settings.
Notice: The slight drifting may continue for a couple of batteries, you
will notice significant improvement in the GPShold & stability
after 4-5 batteries.
Notice: Always perform the calibration away from eletric fields and
metal surfaces.
Trivia: Different brands have different calibration processes, the
process is typically refered to as "the Calibration Dance".
8.0 G-3D 3-axis brushless Gimbal installation
IMPORTANT: REMOVE the battery from the Scout X4 while you install the gimbal
The gimbal is a high-performance eletromechanical design and should be handled with great care. AVOID using force when installing.
8.1 Prepare the G-3D gimbal,
M3x12 screw, spring.
8.2 Slide the gimbal unto the quik
mount rail, the gimbal shouldslide
from the front of the aircraft towards
the rear, gently move it as far back
as possible.
8.3 Install the springloaded
M3x12mm "finger screw" at the
front of the gimbal, this will
secure the gimbal.
8.4 Connect the 9pin white data
cable to the "complex data port"
on the bottom of the X4, then
connect the cable to the back of
the G-3D gimbal.

antenna into the camera, use the
included wrench to gently secure
the antenna, do not use force.
9.2 Release the two M2x4 screws
securing the camera mounting

Fix it with camera fixed frame
(ensure the gap close to the
lens), then screw the M2x4
screw to the camera fixed
frame again.
9.4 Connect the cameras power
cable to the power port on the
G-3D gimbal controller.
9.5 The iLook+ camera is now successfully
installed in your G-3D gimbal.
10.0 Motor Unlock
After succeeding in binding the code, under the stable mode, put the throttle control ball in the lowest position, and stir the direction control ball to the far left.
When the red LED indicator turn solid red, it means that the motor is unlocked. In this condition, if you turn upward the throttle control ball, the motor will run.
Note: For safety, the motors will automatically lock after 10 seconds. This means, if you do not start flying in 10 seconds,
you have to unlock the motors again.
11.0 Motor Lock
Put the throttle control ball in the lowest position and stir the direction control ball to the far right. When the red LED indicator light out, it means that
the motor is locked. In this condition, if you turn upward the throttle control ball, the motor will not run.
