Overview 

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.

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.

Safety 

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.

Included in the Box

The heart of the reliability of DX7, the AR70000 twin receiver delivers a solid RF link and signal reception from further than the eye can see. Enabled with DSM2 it has seen a reduction in latency and along with a 1024 bit resolution makes DX7 faster and more responsive than any PCM system available today.

The four DS821 servos that come with the DX7 are suitable for a wide range of electric, petrol and glow aircraft delivering an impressive 72oz-inches of torque. A precision resin gear train provides competent transfer of the torque providing consistent, reliable performance flight after flight.
