Let the Spektrum bashing begin....

FWIW, I've never had a single problem with my DX6i, Ar500, Ar6200, and Ar6110e. Nothing, nada, zippo but flawless performance. I've used 4.8V, 6V, and lipo batteries with no issues whatsoever. I also used it with a BNF Blade Heli with zero issues and that is using a 1S 3.7v lipo.
