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.
