Install Your Receiver
Binding is the process of programming the receiver to recognize the GUID (Globally
Unique Identifier) code of a single specific transmitter. When a receiver is bound to
a transmitter, the receiver will only respond to that specic transmitter. If you need to
rebind for any reason, please follow these steps:
1. With the transmitter switched ON
2. Power on the receiver,then press the bind button in 3 seconds.
3. Loose the bind button and wait for about 5 seconds.
4. The receiver LED will keep ashing, means it is binding.
5. After the receiver LED stop ashing, it means the binding is done.

Endpoint function allows to adjust max travel volume from -140% to 0%, 0% to 140%.
Endpoint setting works on Channel THRO, AILE, ELEV, RUDD, GEAR, AUX1, AUX2.
When you set endpoint volume smaller than sticker volume, the travel volume of the
particular channel will be adjusted according to the smaller endpoint. For example, if
you set max endpoint to +10%, when the sticker moves to +50%, the actual volume will
be only +5%.
It is the same case when you set endpoint volume higher than sticker volume, shown
as above illustration at right side.
The setting is based on the current model. When you set D/R under Model No.1, the
setting will only work under Model No.1.

Mixing Modes
Mixing modes allow you to mix several channels to be controlled together, changing
one channel to be a new functional channel.
EX7 comes with 3 different preset mixing modes. Follow below steps to set each
mode.
DUALAILE mixes channel 2 and channel 6. When controlling channel 2, channel 6 will
relatively react. Channel 2 only reacts to movement of stick, endpoint setting and sub-
trim setting. When you adjust endpoint or sub-trim setting of channel 2, it will apply to
channel 6 too.
ELEVON mixes channel 2 and channel 3. When controlling one channel, the other
one channel will relatively react.
V-TAIL mixes channel 3 and channel 4. When controlling one channel, the other one
channel will relatively react.

Perform Range Check
FHSS Radio Control System
FHSS is an advanced radio control system with better performance of anti-interference.
EX6 comes with FHSS system, its faster frequence prevents interference signal from
catching up. Therefore using this system allows the radio to work in a more stable
environment.

2.4GHz Trouble Shooting Guide
Problem Possible Cause Solution
The system is not
connected
Your transmitter and receiver
are too close Take transmitter 1 to 3 meters away from receiver
You are around metal objects Try in an area with less metal around
The model selected is not the
model bound to
Check the selected model and ensure you are bound
to the specic one
The model is not the bound
one Rebind your transmitter and receiver
The receiver not
responding during
operation
Low battery voltage Charge your battery
Loose or damaged wires or
connectors between battery
and receiver
Check the wires and connection between the battery
and receiver.
Repair or replace wires and/or connectors
As a precaution, an operational ground range check should be performed before the
rst ight each time out.
Performing a range check is a good way to detect problems that could cause loss
of control such as low batteries , defective or damaged radio components or radio
interference. This usually requires an assistant and should be done at actual ying site
you will be using.
Firstly, turn on the transmitter. Then install the fully charged battery in to the vehicle
and hold it in place with hook-and-loop strap. Connect the battery and install the hatch.
Remember, carefully not to "bump" the throttle stick. Otherwise the propeller will rotate
and possibly cause damage or injury.
With the antenna on the transmitter collapsed(not extended),begin walking away from
the model operating the controls in a predictable pattern(for example, turn elevator up,
and then down. Turn aileron and rudder right, and then left). While moving the control
surfaces, also vary motor rpm.
Remind your assistant to alert you if the controls fail to respond or if they move
suddenly or erratically. You should be able to matain control up to a distance of
approximately 100 feets(30 meters).
If the controls respond erratically or if anything else seems wrong, make certain all the
servo wires are securely connected to the receiver and that the transmitter and receiver
batteries are fully charged. If you can not nd a mechanical problem with the model, it
is slightly possible that there is radio interference somewhere in the area.One option
would be to try another range check at an alternate ying site.
After the range check, fully extend the anternna.
