Receiver - Spektrum AR7000 -DSM2 
The AR7000 Dual Receiver is capable of providing outstanding signal reception beyond visual range, so you can rest assured you have locked-in, precise control no matter how fast you fly.
This is the seven channel DSM2 receiver from Spektrum. Comprised of a compact main receiver that is linked to an even smaller satellite receiver by a 6" lead, the AR7000 acts as a pair of extremely sharp RF "eyes" that each take in a slightly different view of the signal environment. Information from both receivers is then processed by 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 in RC before.
