You dont have to give up pro-class features just because you only need seven channels. The Spektrum™ DX7 system gives you programming for three model types, 250-model memory, voice alerts, a wireless trainer link and more.Programmable Voice AlertsThe DX7 lets you keep tabs on important functions without ever taking your eyes off what youre flying. You can program voice alerts to call out what flight mode youve chosen or report telemetry information on demand. If an alarm goes off, you wont have to look at the transmitter display to see whats happening. The DX7 will tell you.Wireless Trainer LinkThe wireless trainer link gives instructors the option to wirelessly buddy box with another DSM2®/DSMX® transmitter. Once bound to another transmitter, ModelMatch™ technology will allow the DX7 to re-link without having to go through the bind process again.250-Model MemoryThe enormous capacity of the DX7's on-board memory means you will rarely, if ever, need to juggle models between transmitter memory and your SD card.The model memory menu is easier to navigate too. Only memory slots with model settings saved to them will appear. You won't have to scroll through empty slots or move models around if one is deleted.Because the DX7 uses the same software platform as the DX6, DX9 and DX18 Gen 2, you can share model setups with owners of those transmitters as well.Fly Smarter with Built-In TelemetryThe built-in telemetry feature gives you real-time information on things like your model's battery voltage, signal quality, engine or motor temperature, airspeed, altitude and more.*Using the voice alert system, you can program the DX7 to tell you when specific telemetry values reach or exceed limits you define. You can also have it call out a sequence of telemetry values on demand with the flip of a switch. If you want to review telemetry after a flight, the DX7 can be set up to record the data to its SD card.* Requires a Spektrum telemetry module and telemetry sensors, sold separately.Includes Full-Range AR8000 ReceiverYou can take advantage of all seven channels right away with the included AR8000. This 8-channel DSMX® receiver is perfect for all types of aircraft, from warbirds to 3D helicopters. Its also compatible with the Spektrum Flight Log and telemetry modules.Programming FeaturesThe DX7 comes with an impressive list of programming features that rivals that of much more expensive transmitters.
