I. Product Introduction
The C13 is a compact high – definition three – light gimbal. It utilizes a new – generation imaging chip and is paired with a high – definition distortion – free camera. With an effective pixel count of 5 million, it boasts robust 2K video recording and photo – taking capabilities. It supports 30 – times digital zoom, bringing distant beautiful sceneries up close. Equipped with a thermal imaging camera with a resolution of 640×512, it offers a wide field of view and clear images, enabling long – distance observation of various heat sources. In combination with the laser ranging module, the effective ranging distance can reach up to 1 kilometer. The industrial – grade three – axis stabilization structure is adopted, which significantly reduces picture jitter, keeping the image in a stable state at all times. It can be applied in fields such as fire rescue, animal protection, and security monitoring.

V. Installation and Debugging
5.1 The schematic diagram of screw holes and their spacing is as follows:
Note: The screw specifications for the pan – tilt are M2.5*6, and the quantity is 4.
Do not hang the gimbal on the aircraft when it is not in use. Long – term hanging will accelerate the deformation of the shock – absorbing balls, resulting in a decline in shock – absorbing performance and the appearance of the “jello” effect.
When installing the gimbal, the shock – absorbing plates must be kept absolutely perpendicular and parallel to each other. Incorrect installation will cause the shock – absorbing balls to deform, leading to a decrease in shock – absorbing performance and failure of self – inspection.
5.2 Gimbal Working Modes
You can set the gimbal to the hoisting mode or the filp mode in the FPV settings.
Note: The hoisting mode is the default setting at the factory. Do not power on when it is installed in an inverted way.
Please place the gimbal correctly according to the working mode. Incorrect placement may cause damage to the gimbal motor.

5.4 Usage of C13
nstall and open the latest version of the Gimbal FPV software on the remote control. Software download address: http://file.skydroid.xin/SkydroidCameraFPV.apk
① Gimbal startup
After the gimbal is properly installed and fixed, power it on. The gimbal will start up. Please wait until the startup is complete.
② Open the Gimbal FPV software, select the C13, and click to enter.
③ Introduction to the Home Page of the Gimbal FPV
④ FLY GCS Screen Settings
On the top – left corner of the APP’s home page -> Common Settings -> Other Settings -> User Interface -> Video Window -> C13
5.5 Gimbal Parameter Settings
In the parameter settings, functions such as image parameters, color palette, and calibration can be configured.
5.5.1 Image Parameters
Some relevant camera picture parameters can be set.
5.5.2 Pan tilt Control
Click Parameter Settings -> Pan-tilt Control, there are target following and three control methods to choose from, and multiple methods can be selected simultaneously. (Target following cannot be used simultaneously with gesture control.)
①Gimbal target following: After selecting the target to follow, the C13 will automatically track the target.
②Virtual joystick control: You can use the virtual joystick to control the pan and tilt of the gimbal. It also supports functions such as one – key return to the center.
③Gesture control: Control the pan and tilt of the gimbal by swiping the screen.
④ Remote control channel control: Control the pan and tilt of the gimbal, as well as functions like taking photos and recording videos through customizing the remote control channels. (The remote control channels can be checked through the Remote Control Assistant -> Rudder Volume View.)
5.5.3 Correction of Pot Lid Effect
Note: The lid effect has been calibrated upon delivery. Due to the special calibration method, do not calibrate it yourself unless necessary. Before calibration, please contact the relevant technicians from Skydroid for confirmation.
Calibration method:
① Power on the C13 and let it preheat for more than five minutes.
② Select a panel with a flat surface, uniform temperature, even frosting, and low reflectivity.
③ Move the C13 close to and make contact with the target surface. It is optimal when the imaging of the target surface covers the entire field of view without any stray light entering.
④ Click “Calibrate the Lid Effect”, and the calibration is successful when the screen turns into a uniform gray.
5.5.4 Gimbal Calibration
Temperature Calibration: Calibrate the temperature of the pan – tilt during operation to prevent abnormal operation caused by a significant difference between the ambient temperature and the operating temperature of the Inertial Measurement Unit (IMU).
Horizontal Calibration: Place the pan – tilt on a horizontal plane and ensure it is in a stationary state.
Do not touch or shake the pan – tilt.
Vertical Calibration: After the horizontal calibration is completed, the pan – tilt will automatically pitch downwards. Ensure the pan – tilt is in a stationary state, do not touch or shake it, and then click “Calibrate”.
Pan – tilt Fine – tuning: Fine – tune the horizontal and pitch axes of the pan – tilt.
Note: The pan – tilt calibration has been completed before leaving the factory.
Do not click the calibration options unless there are problems with the pan – tilt.
5.5.5 Working Modes
You can set the gimbal to be hoisting mode or flip mode.
Note: Place the gimbal correctly according to the working mode. Incorrect placement may damage the gimbal motor.
5.5.6 Gimbal Speed
The control speed of the gimbal has two modes: constant – speed mode and variable – speed mode.
5.5.7 Color Palette
It is possible to adjust the imaging effect of the thermal imaging camera, with a total of eleven options available.
5.5.8 Laser Ranging
Click the ranging button to perform a single laser ranging. The effective ranging range is 5m to 1 km.
5.6 Set Encoding Mode
You can set screen flipping, view the camera version number, and set OSD display.
5.7 Firmware Upgrade
You can upgrade the gimbal firmware and camera firmware. Do not cut off the power or exit the upgrade interface during the upgrade process. (When upgrading the camera firmware, a TF card must be inserted into the C13.)
