Bought a Phantom v 1.1.1 without a transmitter. I need some advice on which is the "right" transmitter to buy. Found an SR6 on eBay, but have no idea if it will work, and if it does, how to make it work. Second. If the SR6 will not work, then which is the right one to buy? I've heard the DR6 is correct. And finally. . . when I get the right one, how do I "link" them. Thanks.
