Here is one of the most useful home screens. It shows graphically the servo outputs of the radio:
As a first step, we want to get to the Radio Setup and other screens that provide information and
enable the adjustment of settings relating to the basic functioning of the transmitter. Press the left
side of the cross-shaped navigation button for about half a second. We’ll call this LONG LEFT, as
opposed to a short press LEFT. You’ll soon get used to this very important difference.
You are now in screen 1 of 11, Radio Setup:
Channel Order: Using the DOWN part of the cross (we’ll call this the DOWN key from here on) go
to near the bottom of the page where you will see Channel Order. RETA, for example, means
Rudder, Elevator, Throttle, Aileron. This is the order in which the signals for the four primary
channels are sent, via the module, to the receiver, and thence to the servos.
This channel order determines the sequence of controls used throughout the transmitter for setting
up and editing all models and the sequence of channels used on your receiver for the connection
of your servos. To change it, highlight and use the LEFT and RIGHT keys to select the order you
want. For example, modules and receivers using the Spektrum protocol always use the sequence
TAER, as their failsafe arrangement requires the use of channel 1 for throttle.
Stick Mode: At the bottom of the Radio Setup screen you will see Mode, meaning the way in
which the sticks are set up to control the first four channels. This allows you to set the transmitter
programming to match the physical arrangement of its sticks. In many parts of the world, Mode 2 is
most popular. This has aileron and elevator (spring-centred) controlled by the right stick while
rudder (spring-centred) and throttle (friction) use the left stick. The other popular setup, Mode 1,
