Gyroscope Calibration
The gyroscope is used by the drone to sense its position and orientation. If the gyrospace is not well
calibrated the drone will not fly predictably or may constantly lean to one side. This must be corrected
immediately or the drone may increasingly become uncontrollable and crash. The drone may also display
the message “Gyro Calibration” on the remote controller screen. In all these situations, gyroscope calibration
is required.
Note: When the drone is floating on water, it is normal to intermittently see the “Gyro calibration” message - -
this id due to the motion of the water and does not indicate that calibration is required.
Preparation Before your First Flight (or in a new location)
The drone relies on very sensitive sensors to control flight positioning and stability.
Before your first flight, or if your flight is more than 100km from your last flight - you must perform a compass
calibration.
* If you are planning to fly the drone from a boat or pontoon platform, you must calibrate the drone
beforehand on stable ground.
10. Pre-Flight Inspections and Checks: batteries charged, propellers in good condition and correctly
fastened, all motors spin smoothly by manually rotating. battery cover is clean, free of dirt, sand, or any
other contaminants, drone fuselage is sealed and the membrane on the top of battery cover is in good
condition.
12. Unless it is an emergency, NEVER Lock or STOP the motors in flight as this will cause the drone to fall to
the ground and crash.
13. When the low battery level warning is activated, plan to return the drone and land safely before the
battery reaches a critical level.
14. If any obstacles are in the flight path of the drone during a Return Home process, control should be
regained by turning off the Return Home function.
15. If control of the drone feels slow or the drone pulls to one side, try switching to ATTI mode to check if the
drone flies level. In ATTI mode, although the drone will drift with the wind, the body of the drone should
remain level with no joystick input. If this check shows that the drone body is unbalanced, land the drone
and perform a gyroscope calibration.
Description
Illustration
How to calibrate the Gyroscope:
1. Place the drone on a stable horizontal surface free of vibration. Power on
the remote controller and the drone. Wait for initialization to complete.
2. Pull the left joystick down to the lowest position and then fast flick the right
joystick left and right continuously until “INITIALIZING......” appears on the FPV
screen.
3. The drone will now perform gyrocalibration. Do not move or disturb the
drone during this process. When the “INITIALIZING” message disappears from
the FPV display, the process is compete. Restart the aircraft.
* Gyro calibration on board a ship or on a moving platform will not succeed. Calibrate before boarding.
