Fitting Propeller Guards
It is recommended that until you are fully comfortable with the controls and
handling of the aircraft that you install the propeller guards. These will protect
the propellers and aircraft in the event of a crash or hard landing.
Place the propeller guard over the outside of
the propeller and attach it with the screw
provided.
The aircraft comes with a collision avoidance
system, but this will only function in Low
speed mode.
Propeller Installation
Insert the propeller over the motor spindle and use a screwdriver to
tighten the screw.
It is important for the correct blade to be placed on the correct
motor or the aircraft will not fly correctly. Each blade is marked with
an A or B to indicate which motor it corresponds to.
The white rotors are positioned at
the front, and the black at the rear.

Preparing for First Flight
1. Make sure both the transmitter and aircraft batteries are sufficiently
charged.
2. Find a suitable place to fly the aircraft, away from people, buildings and
vehicles.
3. Make sure the throttle stick is centred before turning on the transmitter.
Binding of Radio Transmitter & Receiver
1. Place the aircraft on a flat surface and insert the battery into the aircraft.
2. Turn on the controller.
3. The lights on the aircraft will flash repeatedly, hold the left stick down
until the transmitter binds with it. At this point the lights will illuminate
and stay on.
4. The aircraft is ready to fly.
The aircraft can be flown using either the radio control supplied or by using the
App on a smart device. For details on flying with the App, see page 14.
Sensitivity
The aircraft has 3 levels of sensitivity – High, Medium and Low. To change the
sensitivity, click the speed button. The controller will beep once when in Low
mode, twice when in medium mode and three times when in high mode.
10 of 16
High
In high sensitivity setting the aircraft will be more agile but more difficult to
control if you are new to flying.
Low
In low sensitivity setting the aircraft will be more docile and easier to control.
Medium
In medium mode the sensitivity will be between high and low.
Flight Instructions
Before your first flight make sure you are familiar with the controls of the
aircraft.
Left Joystick – Throttle & Rudder
Right Joystick – Elevator & Aileron
If the aircraft drifts in a particular direction you can trim the controls using the
trim buttons. Select the trim key opposite the direction of drift.
The aircraft can only take off and land by pressing the take off / land button
(click once to take off and once to land). Once the aircraft is airborne it will
hold a steady hover, you are now in control of the aircraft and can use the left
and right sticks to control it.

Note: Should the aircraft be left for a while with no control inputs it will go to
sleep, simply press and hold the take off/land button to reactivate the aircraft.
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.
12 of 16
Headless Flight
The aircraft can be made to fly in Headless Flight by pressing the headless flight
button (9). This will make the aircraft fly without a front or rear. It will fly in
the orientation of the pilot. If you move the right joystick right, the aircraft will
fly right. Move the joystick left and it will fly left. Move the joystick forwards
and the aircraft will fly away from you and pull it back to make it fly towards
you. It does not matter which direction the drone is facing in headless mode.
To calibrate the aircraft for headless flight, place it on a flat surface with the
front facing away from the operator. Then push both the left and right sticks
to the lower left at the same time and hold for 2 seconds.
The indicator lights on the aircraft will change from stable to a fast flickering
for 2 seconds before returning to solid.
Phone installation
Stretch the controller apart and slide your phone/tablet into the
middle of the device.
