If you do by a 3GX, make sure it comes with the USB dongle. It's nessecery to upgrade the firmware!
One other thing, RX-2637H-D is for a motor driven tail without a servo so it wouldn't work with the rex anyways
i'm pretty sure that rcvr would work with a trex/clone you wouldn't even use that tail motor output. for the main motor all you would need is a brushless esc.
