Binding your DSSS series 2.4GHz R/C system
Place the transmitter and the receiver within one (1) metre of each other.
Do not press the bind button when the transmitter and receiver are bound, as it will break the bind!
1. Plug the bind plug into the receiver in
BATT. socket. Connect a power supply to
the receiver. The receiver’s LED will flash.
2. Press the transmitter’s bind button, then
turn on the transmitter.
3. The LED on the receiver will go solid.
This indicates that the bind is successful.
4. Remove the bind plug, the LED will flash.
5. Press the transmitter’s bind button again.
The indicator light will flash for a few seconds.
Once it turns green, the transmitter is ready
to use.
6. The receiver’s LED turns solid again,
which means that the radio system is bound
and ready to use.

Make sure the model’s CoG is within the range
shown here. In the ideal situaion, the CoG is
between 60~70mm from the leading edge of
the wing.
PRE-FLIGHT INSPECTION AND ADJUSTMENT
1. Install 8 ‘AA’ cells into the transmitter according to the battery’s polarity, then turn on the transmitter.
Install the full charged flight battery into the battery compartment of the fuselage and connect the battery
to the electronic speed controller (ESC).
2. The right stick of transmitter controls the aileron when pushed left or right: when you push the stick
to the left, the left aileron of plane will lift and the right aileron of plane will drop in response and vice versa
for when the aileron is pushed right.
Before flying, put the trim of aileron to the middle position and then adjust both the ailerons to the neutral
position with the control rod.
3 .The left stick on the transmitter controls the power of motor when pushed backwards for forwards
When holding the fuselage of the plane, please keep objects away from the propeller to avoid hurting
people or damaging the propeller. If you pull the left stick to the lowest position, the motor will stop.
Now the motor is on standby. You can check the motor by pushing the stick up slowly.
4. The up and down movement of the right stick of transmitter controls the movement of the elevator.
When you pull the stick back, the elevator of plane will lift and vice versa when you push the stick forward.
The best state before flying is the elevator sticks and trim are all in the neutral position.
5. The left stick on transmitter controls the rudder when you push the stick to the right, the rudder of
plane will turn right and vice versa when the stick is pushed left. The rudder stick and trim should be neutral
before flying.
6. If the servos and motor give no response during setup, please check all connections and make sure the
battery is fully charged and the transmitter and receiver are bound together.
7. Check the CoG of the model. The proper CoG position should be 60~70 mm away from the leading edge,
please refer to the picture. If in any doubt contact your dealer.
Note: The transmitter and receiver must be the same 2.4GHz protocol. Unmatched sets will not be
compatible and may cause loss of control.

IN-FLIGHT ADJUSTMENT
1. Before flight a radio range check should be conducted. A minimum distance of 200m between the radio
and model with the model on the ground whilst maintaining full control of the model is recommended.
If you cannot control the model at 200m, then do not fly!
2. Make sure both your flight pack, and your radio batteries are fully charged before attempting to fly.
3. During flight, if the model is ‘yawing’ to the right, adjust the rudder trim to the left to correct this.
If the model is ‘yawing’ to the left, then adjust the rudder trim to the right.
4. If the model is trying to drop its nose during flight, then adjust the elevator trim downwards to correct
this. If the model is trying to lift its nose, then adjust the elevator trim upwards.
Upon landing, if you have had to make excessive trim adjustments to the elevator, it is advisable to
double-check your centre of gravity.
If your centre of gravity is correct, then you may wish to check your elevator clevices and ensure
your control surfaces are level.
5. If the model is ‘banking’ to the left, then adjust the aileron trim to the right. If the model is ‘banking’
to the right, then adjust the aileron trim to the left.
HELPFUL TIPS
1. If you have a flight simulator we recommend that you practice with it before flying your radio control
model. It will give you an understanding of how the transmitter operates the model and increase
your chances of a successful first flight.
2. Before flight, check all control surfaces operate in the correct direction and move freely.
3. On your first flight, we recommend flying to a height of around 100m and reducing the throttle to
30%. This will allow you to get used to the way the model handles and performs.
4. When taking off, position yourself into the wind, this gives better airflow over the wings and allows
the model to take-off more easily.
5. Always fly your model in front of you, never fly behind yourself or over your head.
6. To increase flight times, spare battery packs are preferred over a larger battery as this will not
upset the performance or weight distribution of the model.
