The DX3.0 is
an improvement on the DX2.0, offering three
channels and a four model memory, as well
as the proven second generation 2.4GHz DSM
(Digital Spektrum Modulation) equipped computer
steering wheel radio system. As with all
the Spektrum system it offers security without
even having to think about it, unlike ordinary
2 channel radios. |

The DX3.0 system works
at 2400MHZ (2.4GHz) as opposed to the conventional
27 and 40 Mhz that has been in use for model
car since it first began. With a frequency
this high there are significant advantages.
The lower positioned frequencies are so far
away they cannot in any way interfere, or
be interfered with by Spektrum. Also the
ultra high frequency puts Spektrum well out
of the range of model-generated radio interference
like motors and ESC noise on electric powered
cars and engines, clutches and bearings on
gas powered cars. All the problematical issues
that can now occur using 27 and 40MHz radios
are completely eliminated with this radio.
So it’s bye-bye interference. |

Spektrum radios are smart,
they are aware of what is going on around them.
There’s no frequency crystals, no setting
frequencies, Spektrum takes care of all of
this for you. When you turn DX3.0 on it scans
to find one of the 2.4GHz’s 79 channels
that are free and then occupies and starts
to transmit on it, meantime its bound receiver
scans for the transmitter’s GUID, a unique
identification code that it shares with it.
When it finds this, the two lock and form a
totally secure RF link. In the unlikely event
of all 79 channels being occupied DX3.0 will
go into hold mode where it will not transmit
and interfere with any other 2.4GHz device,
but continue to scan until it finds a vacant
channel. |

The transmitter features a
clear LCD screen that allows you access to
all of the functions available. Servo reverse,
end point travel for both steering and throttle
and digital steering and throttle trims are
programmed via the digital trims, grip levers
and function buttons. Four-model memory with
a three-digit display is also programmed via
the screen and function buttons. Although not
supplied with the radio there is a charging
jack already installed should you wish to power
the transmitter with rechargeable batteries. |

The SR 3000 receiver is a
three-channel DSM receiver. When first set
up it has to be bound to the receiver and when
doing so failsafe settings (low throttle, left
turn possibly) are set to be automatically
reverted, should the signal be lost, rendering
the vehicle safe and recoverable. |

Two servos are included in
DX3. Both are race quality and speed units
however in gas car applications in particular
the Z590 high torque servo is intended for
use on the steering to deal with the extra
forces involved. |
