12.4 OPTICAL FLOW
The optical flow system consists of optical flow lens modules. This system
will obtain the Drone's position through optical images, which will ensure
safe flights and accurate positioning. See below for reference, so you can
see where the optical flow camera is located on your Drone.
NOTE:
• Optical flow mode is good to fly indoors or outdoors with low GPS coverage
The measurement of accuracy whilst in the optical flow function can be affected if:
– You're flying fast at low altitude (below 0.5 metres) - the optical flow system may not
be able to locate the Drone.
– Flying over monochrome surfaces (such as pure black, pure white, red green), surfaces
with strong reflections, water or transparent surfaces
These factors can cause optical flow failure, which may cause the Drone to go into fixed
altitude mode.

13.1 GYROSCOPE CALIBRATION
Put the Drone on flat ground and pull both thumb sticks to the bottom
left corner together at the same time. (See picture for reference).
The indicator light will start flashing green,
rapidly which means calibration has started.
It will turn to solid green which confirms
the Gryroscope Calibration is complete.
