Once is started, the selected function is switched from the joystick to the control knob. To return

BOAT Mode
In Boat mode, the SD4 can effectively be controlled like a boat on the surface of the water. With a
maximum surface speed of 1m/s.
Changing Gimbal Mode
Normally, gimbal cameras dynamically adjust the camera angle so that the recorded image remains flat
regardless of the orientation of the drone. On supported gimbal cameras, the gimbal can be locked in
position so that the camera is locked to the drone position. Press and hold the Gimbal Mode button to lock
the gimbal. Short press the Gimbal Mode button to return to normal balanced gimbal mode.
Payload Release (PL1-S) Switch
The SD4 remote control can accommodate two separate payload release mechanisms. To open a payload
release, short press the selected Payload button. To close the payload release, short press the Payload
button again.
The SD4 payload release (PL1-S) is equipped with an extension arm, which can be installed according to
different gimbal cameras. When used with gc3-s and gc2-s, PL1-S needs to install extension arm When
used with GC1 and FAC, it is better to remove the extension arm.
Low Battery Alarm Warnings
The SD4 has three battery alarm levels to help the pilot manage
the drone’s battery life.
Each time a battery
level alarm is activated, the remote control will beep and vibrate to alert the pilot.
Level 1 alarm:
The drone battery level has reached 14.6V. The remote control screen will display a large
battery icon in the middle of the screen to prompt you to return the drone if it is not nearby and prepare to
land. The Drone Status Indicators on the rear arms will flash a pattern of 3 yellow lights.
Level 2 alarm:
The drone battery level has reached 14.4V. The battery icon on the FPV screen will flash.
The battery level is now below 20% and you should plan to land the drone safely.
Level 3 alarm:
The drone battery level has reached 14.2V. After 10 seconds, the drone will initiate an in-
place Auto Landing to protect the drone and battery. The LED on the read arms will flash yellow constantly.
The FPV will display “FS” in the lower
-left corner to indicate that flight-safety mode is active.
Should it be necessary to prevent the Auto-Landing, switch the drone into ATTI mode to regain manual
control and land the drone. If the pilot continues to fly the drone below 14.2v there is a risk that the battery
will not be able to maintain flight and the drone will crash.
