1.2 Gimbal Camera
The EVO Max 4T integrates four sensor systems: a wide-angle camera, zoom camera,
infrared thermal imaging camera and laser rangefinder.
1.2.1 Introduction to the Gimbal Camera
The EVO Max 4T gimbal camera has a high-precision three-axis motor structure, which can
keep the camera stable when the aircraft is flying, thus ensuring image stability and clarity. The
mechanical rotation angle of the three-axis motor of the gimbal (pitch: -135°~45°; roll: -45°~45°;
Yaw: -45°~45°) is shown in Figure 1-6 here.

Chapter 1 Aircraft 7
EVO Max 4T User Manual
Table 1-7 Gimbal Camera Details
No. Name Description
1 Cylindrical Holes
The two cylindrical holes at the front of the gimbal camera are
used to fix one side of the gimbal camera to the two "fixed pins"
in the "aircraft nose gimbal cabin".
2 Yaw Axis Motor It is used to control the moving range of the camera to rotate
left or right with its own axis (mechanical range: -45°~45°).
3 Laser Range
Finder
The distance is accurately determined by measuring the time
from the start of the laser emission to the time when the laser
is reflected from the target.
4 Wide Angle
Camera
1/1.28" CMOS, 50 million effective pixels. The wide-angle
camera is used to capture images with a larger field of view
within a shorter shooting distance.
5 Dampener Mount Used to support dampeners and gimbal cameras, etc.
6 Dampener Used to buffer the vibration of the gimbal camera.
7 Roll Axis Motor Used to control the moving range of the camera to roll left or
right (mechanical range: -45°~45°).
8 Infrared Thermal
Imaging Camera
radiometric measurement range: -20℃to 150℃, 0℃to 550℃.
The infrared thermal imaging camera is used for radiometric
measurement and night vision, which can monitor the
temperature distribution of the measured target in real time, so
as to judge the state of the target.
9 Pitch Axis Motor
It is used to control the moving range of the camera up or down
(mechanical range: -135° to 45°, controllable movement range:
-90° to 30°).
10 Zoom Camera 1/2" CMOS, 48 million effective pixels. The zoom camera is used
to shoot distant scenes, making the distant scenes clearer.
11 Connector Cover
The protective cover above the connector is used to fix the
other side of the gimbal camera to the bottom of the aircraft
fuselage.
12 Connector
The connector of the gimbal camera is connected to the
connector slot at the bottom of the aircraft fuselage.
In order to ensure that the product can work normally, the ambient temperature during
use must be between -20°C and 50°C.
Be sure to use the gimbal protective cover to fix the gimbal camera, especia
lly when
transferring or storing the aircraft, to avoid da
mage to the gimbal camera due to
accidental rotation or bumping.
Please remove the protective cover of the gimbal before turning on the gimbal, otherwise
it may cause damage to the gimbal motor and circuit.
When turning on the power switch of the aircraft, the gimbal will automatically rotate to
perform self-check and calibration, please make sure there is no object near the gimbal to
