Aircraft Functions and Features
Obstacle Avoidance Sensor
Install the collision sensor to the bottom of the aircraft as per the below
diagram:
Collision avoidance will only work in Low speed mode. The sensor will work to
keep the drone around 2m away from any obstacles. Solid white objects (e.g.
walls) will be the easiest detected objects. Glass will not be detected. If an
object is detected the aircraft will move in the opposite direction to avoid it.
Smart Return
The aircraft can be made to return in a fixed direction by pressing and holding
the return button. When the aircraft is turned on it will remember the
direction it is oriented and upon activation of the Smart Return feature it will
fly back in that direction. NOTE: Be careful to orientate the aircraft with the
rear tail facing towards you if you want the aircraft to fly back towards you
using the smart return mode. You can retake full control of the aircraft at any
time by moving the control sticks. The aircraft will not return to where it
started, it will simply move in the direction it was orientated when turned on.
