TURN UP, TURN ON AND FLY.

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. As a natural evolution of DX6, DX7 has during its year and a half of development undergone thousands of test flights in over 200 different aircraft. From big scale planes to gas and glow helicopters, unlimited class sailplanes, all types and sizes of electrics and even in turbine powered jets Spektrum 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.

AR7000
The AR7000 dual receiver is at the core of the DX7’s sturdy RF link. Comprising two individual receivers joined by a 150mm lead, each receiver has an independent view of the signal environment. Data collected by each receiver is processed by patent pending Spektrum software, and combining the two streams results in the most accurate ‘picture’ of an RF signal ever produced. From a purely practical point of view both receivers collect their signals via very short 75mm aerials making it unnecessary to have them exposed externally and thus making installation much easier.

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.

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.

Servo Compatibility
The DX7 system is compatible with all commercially available servos as well as speed controllers and gyros.

AR6000 Compatibility
The DX7 is compatible with the AR6000 park flyer receiver so if you have this type of plane kitted out for DX6 you can now use the DX7 transmitter with the advantage of ModelMatch and a slightly faster response time.
