Based on the DX8 platform, the new DX7s has a 20 model memory, (helicopter or airplane) and is loaded with a number of valuable features not found in any other 7-channel in its class, making it the new radio of choice for 7-channel computer radio systems.
Building on the successful Spektrum DX7 radio, the DX7s has improved ergonomics and a much more expansive and user-friendly software base in AirWare. The new DX7s offers sophisticated programming to meet the demands of even the most experienced airplane and helicopter pilots. An easy-to-use rolling selector combined with intuitive software makes setting up models quick and easy.
The DX8 and is telemetry ready, the transmitter's screen displaying real-time telemetry including receiver battery voltage, signal quality and flight log data; which includes antenna fades, frame losses and holds (failsafes). External sensors (sold separately) allow rpm, external voltage and temperature to be displayed on screen in real time and alarms can be programmed to warn of low battery, over temperature, exceeded rpm and diminished RF signal strength.
The DX7s features a SD card slot allowing data transfer to and from the radio allowing the transfer of single and multiple models as well as firmware updates. This functionality gives the DX7s the opportunity and luxury of model presets, eliminating programming errors, and reducing the time to get new models flying.
The top switch locations have been changed to improve ergonomics, and the popular roller/selector is conveniently placed on the right side of the radio for easy thumb use for software navigation. Gimbals are quad ballraced for a smooth action and the DX7s is of course LiPo capable.
The DX7s features a built-in multi-chemistry charger designed to charge 4-cell NiMH and 2-cell LiPo batteries at a charge rate of 200mAh. The charge jack on the right side of the transmitter is non-polarity-critical, allowing the use any type of 12-volt supply to charge the battery regardless of connector polarity.
