DX6 6 CHANNEL SYSTEM W/ AR610 RECEIVER SPM6700 ANOTHER BLOW TO THE STATUS QUO The DX6 has been designed from the ground up to deliver way more than you would ever expect from a 6-channel transmitter in its price range.

You also get other extras like voice alerts, a wireless trainer link and enough internal memory for up to 250 models.
