Guys, please don't try to talk people into the DX7 for nearly double the price of the DX6i... That's obviously my opinion but here's why: I fly a DX6i with over 1000 flights on it problem free. I've owned the radio since the day it was released on the shelves. I use my DX6i & AR7200 (yes 7ch RX as I use a dual a123 redundant power setup) to fly my 30% Edge 540T giant scale and it works PERFECTLY. This includes a channel for opti-kill too. So there really is no point buying a DX7 (unless you're a heli flier possibly). If you need more than 6 channels, you're also at the point in this hobby where you need more than 7 as well. Buy at least an 8 or 10 channel radio and save the 1/2 step-up. Not to mention, the DX8 is on for $400 which makes it extremely superior to the 7 in every way. To top it off the DX6i is new and has more advanced programming than the 7 as well.

Anyway just a piece of advice for those recommending radios!
