Spektrum DX7 2.4GHz
Transmitter Only
Special Price to Clear
DX7
for all types of Planes
and Helicopters
With
DX7 you can fly any
size plane or helicopter
that can be controlled
using a seven channel
radio system. The
Spektrum DX7 has been
tested by numerous
experienced pilots
in all types of environments
to be absolutely sure
it delivers 100% reliability
and performance.
Let the technology
do the work.
After all the radio
equipment is installed
into the plane, the
receiver of your DX7
is ‘bound’
to the transmitter,
a short simple process
that takes only a
few seconds. Once
done the two are linked
by a unique identification
code that means they
can only communicate
with each other. No
other Spektrum or
regular 35, 27 or
40MHz equipment will
recognise or interfere
with your DX7, and
conversely it won’t
interfere with anyone
else’s equipment.
ModelMatch™
It’s not uncommon
to forget to check
that the model that
is about to take off
is the one that’s
profiled in the transmitter
display. The consequences
can be disastrous
though. Once again
Spektrum redefines
flight safety with
ModelMatch™
by making this kind
of error a thing of
the past. With DX7
a profile code is
embedded into the
receiver and if it
doesn’t match
the one embedded in
the signal, indicated
by the model name
on the display, the
model’s controls
simply won’t
respond.
SmartSafe™
SmartSafe™
deals subtly differently
with two safety critical
scenarios, one of
which is especially
important for electric
powered planes. Fail-safe
settings are established
during the binding
process at the positions
of the sticks, usually
low throttle and neutral
on other channels.
The first scenario
is that the receiver
is turned on without
a signal from the
transmitter. In this
event all of the channels
go to the fail-safe
positions set during
the binding process
but the receiver doesn’t
send any signals out
on the throttle channel,
so the speed controller
cannot arm and start
the motor.
Once the transmitter
is turned on and an
RF link is established
the receiver will
send out a low throttle
signal and arm the
speed controller once
the stick is positioned
at low throttle. From
that point it functions,
as do the other channels,
as normal.
The second case scenario
is that the signal
is lost whilst both
transmitter and receiver
have an established
RF link. In this event,
as unlikely as it
is, SmartSafe™
will take the throttle
channel to its setting
programmed during
the binding process,
while all other channels
stay at last position
held.
DualLink™
for reliability
Aeroplanes are a
little more complicated
when it comes to retaining
a solid RF link to
than surface bound
craft because they
manoeuvre in three
dimensions. Surface
craft like boats and
cars are fixed in
one plane so orientation
to the receiver’s
aerial, while it’s
pointing at the sky
as it should, remains
constant ruling out
signal fade, a condition
that reduces range.
To solve just that
problem with aeroplanes
Spektrum employs the
use of two separate
radio channels and
receivers, each with
its own aerial. The
radio transmits the
signal on both frequencies
simultaneously and
because the two aerials
have different orientation
should one of those
signals be lost, for
even milliseconds,
due to its orientation
to the transmitter
the other one will
still be on-line.
The net result is
no loss of signal,
no interruption, no
dropouts, no problems.
A solid RF link is
there all the time.
DSM2™
DX7 features DSM2™,
which is second generation
DSM. DSM2 provides
all the benefits of
DSM but with the added
bonus of doing it
faster. By processing
the signal faster
than any PCM radio
system available today
and at 1024 bit resolution
the link that connects
pilot and plane is
sharpened making him
feel more in contact
and control of his
plane.
ServoSync™
A new feature on
DX7 that re-sequences
the bits of data based
on the type of mixing
selected. So if dual
elevators or 3-servo
CCPM has been set-up
ServoSync™ will
see to it that those
servos are performance
optimised by receiving
their impulses together.
This results in a
more positive feel
to control input.
Servo Compatibility
The DX7 system is
compatible with all
commercially available
servos as well as
electronic speed controllers
and gyros.
