The AR7000 dual receiver that pairs with the DX7 Transmitter is key to the systems incredibly robust RF link. Information from two receivers is processed by a patent-pending Spektrum software that takes information from each receiver and combines it to form the most vivid picture of an RF signal than has ever been possible before.

Featuring DSM technology and weighing in at only 7 grams, the AR6000 receiver is specifically designed for electric powered planes and helis. Better yet, it will deliver reliable range exceeding that of any other receiver sold specifically for parkflyers. Designed to work with Spektrum's DX6 transmitter. Features: DuaLink TM(patent pending) incorporates two receivers in one. Ultralight 7 grams. Compact design 39 x 39 x 9mm. Smart fail-safe prevents motor start up if Tx is off and gives low throttle if signal is lost. Short 3.75 inch antennas for mounting convenience. Easy bind plug.

The DS821 servo is a powerful, accurate sport digital servo recommended for RC airplane applications up to 1.20-size. For helicopters, the DS821 operates best with 30-size glow models, and up to 50-size electric. Loads and vibration in larger models may cause premature failure of the servo resulting in damage or injury to property and persons.

The DX7 Microlite system includes the feather-light, 3.5g AR6100 Microlite Receiver and three DS285 Digital Sub-Micro Servos. In addition to being the lightest receiver in its class, the AR6100 can be operated with a wide range of input voltage (3.5V - 9V). And the digitally precise DS285 servos offer more than enough speed and torque for any small electric application. The DX7 DSM2 transmitter features airplane and heli software, 20-model memory and all the programming functions you would ever need for anything requiring 7 channels. And the large dot matrix, LCD screen makes accessing and using the software simple and straightforward.
